THE NEW & IMPROVED SPC TOKEN
We are excited to announce beta access to the new ERC-20 SPC token (v2) that comes with DeFi features!Modern Ethereum Decentralized Finance (DeFi) products require ERC-20 tokens to have certain features in order to be deposited, traded, borrowed, and more. Our current SpaceChain ERC-20 token lacks these standard API features that many DeFi products expect. But, with our upgraded ERC-20 token (v2), you’ll be able to unlock more financial products as it is plugged into DeFi instruments such as Uniswap and Balancer decentralized exchanges. You’ll also have access to other lending pools, collateral, and DEX style blockchain instruments.The advanced SPC token (v2) opens doors to better market outcomes that benefit all users of our ecosystem.Seamless and voluntaryThe entire upgrade process is permissionless and secure as it is handled 100 percent by smart contract on the Ethereum blockchain. The swap process is also optional and voluntary, allowing you to choose when and how much to upgrade.You may continue to hold your ERC-20 SPC tokens (v1) and swap to the SPC token (v2) today, tomorrow or 10 years from now. SPC (v1) can still be transferred to others, who can convert them to SPC (v2).One-to-one exchangeThe swap is on a 1:1 equal basis. This guarantees the Spacechain SPC token promise of keeping supply at 1 billion. The token upgrade process takes SPC tokens (v1) — either burning them or sending them to null address 0x0 — and mints the exact same number of SPC tokens (v2).Audited and certifiedWe are pleased to share that the security audit of SPC token (v2) has been completed successfully by Coinspect. They evaluated the security of the smart contract source code, deployment, and user tokens migration procedures. The assessment identified a risk scenario where added caution ━ additional confirmations ━ should be applied at the user level, and SpaceChain modified its upgrade instructions accordingly. No high or critical severity issues were found in this audit.Available on decentralized exchanges and moreThe SPC token (v2) is currently available on Uniswap, Balancer, 1inch, and HitBTC.Contract address and explorer for new SPC token (v2)Contract address: 0x86ed939b500e121c0c5f493f399084db596dad20Explorer: https://etherscan.io/token/0x86ed939b500e121c0c5f493f399084db596dad20RecommendationsWe suggest that you upgrade a small amount of SPC tokens first to verify that you understand the process and are able perform the swap correctly before risking larger amounts. This beta access is recommended for early adopters and risk takers who want to take advantage of the advanced benefits of the new SPC token (v2).The swap process (ERC-20 only)Follow this step-by-step guide to upgrade your tokens from SPC (v1) to SPC (v2).Connect ━ Connect your wallet via this application through metamask, or scan the QR code through any ethereum wallet.Send ━ Click “Send SPC to Vault” and approve the transaction from your wallet.Upgrade ━ Upgrade your token from v1 to v2. You can also verify the balance here.━━FAQQ1: Why is a token upgrade recommended?SpaceChain is encouraging all SPC token holders to migrate to SPC (v2), a new, more advanced token.Since the release of the original SpaceChain token on qtum (“SPCv1.QTUM”) and original SpaceChain token on Ethereum (“SPCv1.ETH”), many new DeFi financial products have been designed, requiring more advanced token features.The SPC token (v2) will be plugged into DeFi instruments such as Uniswap, Balancer, Kyber, and other lending pool, collateral, and DEX style blockchain instruments for SpaceChain token holders to use.This is intended to open a new door into token and market health incentives and programs that benefit all SpaceChain token holders.Q2: Does the total SPC token supply change?No. The token supply remains capped at 1 billion. Each SPC (v1) to SPC (v2) upgrade exchanges tokens on a 1:1 basis.The token upgrade process takes SPC tokens (v1) ━ either burning them or sending them to null address 0x0 — and mints the exact same number of SPC tokens (v2)Q3:Am I required to upgrade? What happens if I do not upgrade my tokens immediately?The upgrade process is opt-in and voluntary. You may hold and trade SPC tokens (v1) and always swap 1:1 SPC (v1) for SPC (v2), today, tomorrow or 10 years from nowQ4: What happens if I never upgrade my tokens?SPC (v1) can still be transferred to others, who can convert them to SPC (v2).Q5: Are exchanges required to upgrade?No. Each exchange may choose when to upgrade. It is expected that most exchanges will want to upgrade for a better ecosystem.Q6: What if I’m still holding on to SPC’s QRC20 tokens?You may swap them to SPC (v2) directly by filling up this form. We will contact you via the SpaceChain official email or Telegram account (@SpaceChain) to guide you through the process.Still got questions?

사진: 유럽 우주국우주/블록체인 업계 사상가들과의 시리즈 인터뷰 3편에서는, SpaceChain UK 기술 매니저인 Ziheng Xiang 과 흥미로운 대화를 나누었고, 회사와의 역할과 산업 전반의 향방에 대한 그의 견해에 대해 자세히 알아보았다.당신은 회사의 블록체인 기술과 양자 커뮤니케이션 전문가 입니다. SpaceChain체인 재단에서 여러분의 배경과 활동에 대해 자세히 알려주십시오.Ziheng: 개인적인 차원에서, 저는 제가 양자 의사소통에서 박사학위를 취득하기 위한 나의 지속적인 헌신을 설명해줄 학계의 중요성을 항상 강조해 온 사람으로 보고싶습니다. 이 노력은 반도체 양자점을 가진 단일 광자원을 만들어 광섬유 네트워크에 배치하는 것을 보아왔습니다. 최종 목표는 얽힌 단일 광자 쌍을 생성하는 것이며, 이는 보안 통신 및 양자 네트워크에 매우 유용합니다.전 SpaceChain 재단에서 블록체인과 우주기술의 적용에 대한 연구를 주도하고 있으며, 다양한 수단을 통해 양 영역의 통합을 옹호합니다. 이 애플리케이션의 예는 블록체인과 머신러닝이 시너지 효과를 발휘하여 EO (Earth Observation) 데이터를 분석하고 의료 데이터 내에서 블록체인의 프라이버시 보호를 제공하는 것에서 볼 수 있습니다.앞으로 몇 년 동안 우리가 보게 될 위성 기술의 발전은 무엇입니까? 그들은 신우주경제에 어떻게 적용하고 직접적으로 영향을 미칠 것입니까?Ziheng: 이것은 정부로부터 민간 기업 주도의 이익에 이르기까지 그리고 개인에서 네트워크로 연결된 벤처에 이르기까지 두 가지 차원에서 고려되어야 하는 극히 광범위한 질문입니다.앞으로 몇 년 동안, 우리는 일반인들이 위성 기술을 더 쉽게 접할 수 있게 되는 극적인 변화를 보게 될 것입니다. 개발자들은 또한 우리가 우주에서 진보를 할 수 있도록 하고 혁신의 효율성을 높일 것입니다. 이리듐과 스페이스X 는 이미 이 분야에서 거대한 발걸음을 내디뎠습니다. 위성 기반 네트워크의 전세계적 접근성은 최종 목표이며 우리는 그것을 향해 빠르게 나아가고 있습니다.이 모든 것이 산업계를 더욱 분산시키는 데 도움이 될 것입니다 –SpaceChain 재단의 핵심 가치 제안 중하나; 현재 우주 산업은 자원 부족으로 상업화의 장벽에 진면해 있지만, 이 모든 것이 곧 바뀔 것이라는 큰 전망이 있습니다. 지금은 기술자와 중소기업 모두에게 흥미진진한 시간입니다.Ziheng Xiang 은 로마에서 열린 NSE ExpoForum 2019의 사이버 보인 패널에 속해 있었다.SpaceChain 재단의 분산형 위성 인프라(DSI)와 그 이면에 있는 기술이 업계의 공백을 어떻게 메울 것인지에 대해 좀 더 자세히 설명해 주시겠습니까?Ziheng: 우리의 분산형 위성 인프라(DSI)는 여러 참여 주체가 소유하는 위성 별자리를 만드는 것을 목표로 합니다. 이리듐이나 스타링크와 같은 기존 또는 제안된 별자리와는 다른 DSI는 특별히 그 누구도 소유하지 않습니다. 진정한 오픈소스 블록체인 네트워크인 우리의 DSI는 그것의 운영과 유지관리에 기여하는 다른 당사자들이 있을 것이며 참여하는 인공위성은 본질적으로 블록체인 등록물인 게이트웨이를 통해 정보와 업무를 수신할 수 있게 됩니다.블록체인의 가장 중요한 부분 중 하나는 노드 간 합의에 이르는 메커니즘입니다. 우리는 DSI가 정보 동기화 및 기록 추적 가능하도록 하기 위해 이 개념을 사용하고 있으며 참가 위성은 관련 정보를 보고 공유하고 중계할 수 있게 됩니다. 또한 그것은 우주 기술 산업 전반에 걸쳐 신뢰와 자동화를 구축하는 방법입니다.2019 ESA의 PhiWeek 부트캠프에서 Ziheng Xiang이 블록체인의 우주 공간 개입에 대해 설명하고 있다.2019년 ESA의 PhiWeek부트캠프에서 멘토였습니다. 그것에 대해 우리에게 조금 더 공유해주실 수 있나요?Ziheng: PhiWeek 부트캠프는 유럽우주국(ESA)이 Phi-Week의 틀에서 주최합니다. 그것은 본질적으로 우주 기술에 대한 혁신적인 아이디어에 대해 참가자들이 협력하기 위한 워크숍이었습니다.SpaceChain재단의 지정 대표와 나는 멘토 역할을 채워 블록체인이 우주에서 사용될 수 있는 길을 둘러싼 화제를 불러일으키기 위해 초대받았습니다. 특정 산업 주제에 대한 논의는 물론 자문도 제공하고, 우리만의 기술을 공유하는 모습을 볼 수 있는 매우 생동감 넘치는 행사였습니다.지와 내가 한 프레젠테이션은 정말 감동적이었던 것 같습니다. 워크숍이 끝난 후 SpaceChain체인 재단과 함께 일하는 것에 관심을 보인 참가자가 몇 명 있었습니다.또한 우주 용어를 사용하고 주제를 지휘하는 것에 관여하고 있다는 피드백을 제공한 일부 참가자들에게 놀랐습니다!2019 ESA의 PhiWeek 부트캠프에서 Ziheng Xiang이 블록체인의 우주 공간 개입에 대해 설명하고 있다.향후 몇 년 동안 블록체인의 기술이 우주 산업과 어떻게 통합될 것으로 보십니까?Ziheng: 전 확실히 이 분야에서 많은 잠재력을 봅니다. 말하자면, 우리는 업계 전반의 효율성 향상과 보안 개선을 위해 잠시 기다려야 할 것입니다.블록체인은 상업화를 위해 우주산업에 금융과 제휴 이용사례를 가져오는 데 필수적인 역할을 합니다. 업계 내 블록체인의 발전을 위한 가장 중요한 원동력이라고 생각합니다.블록체인이 기여하는 시나리오가 아닌 중추적인 역할을 하는 탄탄한 애플리케이션 시나리오도 필요하며, 그것이 지금 우리가 연구하고 있는 것입니다.우주 산업에서 가장 흥미진진한 점은 무엇일까요?Ziheng: 어디서부터 시작해야 할까요? 전 이 흥미진진한 산업의 일원이라는 것이 매우 자랑스럽습니다. 우주의 1조분의 1이라도 발견하고 탐험하는 것이 얼마나 놀라운지 상상해 보세요. 우리가 매일매일 부딪치는 것이 비현실적이고 억지스럽게 보일 수도 있다는 것을 알지만, 나는 항상 우리가 어디까지 왔는지 반성하고 있습니다.제 생각에 그 산업은 또한 우리를 덜 자기 중심적으로 만들며, 우리는 단지 거대한 바다에 빠져 있을 뿐이라고 생각하게 합니다. 이것을 인정하는 것은 가치 있는 일이기도 하고 겸허한 일이기도 합니다.지금까지 SpaceChain에서 일해 본 경험은 어떠세요?Ziheng: 이런 말을 할 줄은 몰랐는데, 비디오 게임을 하는 것보다 훨씬 더 좋습니다!진지하게 생각해 보면, 이렇게 놀라운 플랫폼을 통해 기여하고 변화를 만드는 능력은 저를 극도로 만족하게 합니다. 또한 우리가 한 팀으로서 가까운 미래에 매우 높은 곳에 도달할 것이라고 생각합니다.스페이스체인 COO Alessandra Albano와 Fossa Systems의 CEO 및 공동창립자 Julian Fernandez의 인터뷰 시리즈를 확인해보세요.당신은 Ziheng 및 스페이스체인 팀원들을 만나볼 수 있으며, 스페이스 체인 웹사이트에서 Twitter혹은 newsletter를 구독하여 최신의 업데이트상황과 뉴스레터를 확인해 보세요.위성, 부트캠프 및 비디오 게임 was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

Of Satellites, Bootcamps an...
Photos: European Space AgencyIn the third instalment of our series of interviews with space and blockchain industry thought leaders, we had an interesting conversation with SpaceChain UK’s Technology Manager Ziheng Xiang and found out more about his role with the company and his views on where the overall industry is heading.You’re the blockchain technology and quantum communications expert in the company. Tell us more about your background and what you do in the SpaceChain Foundation.Ziheng: On a personal level, I would like to see myself as someone who has always placed an emphasis on the importance of academia, which would explain my continued dedication to obtaining my PhD in quantum communications. This endeavour has seen me creating a single photon source with semiconductor quantum dots and deploying it across an optical fibre network. The end-goal is to generate entangled single photon pairs — extremely useful for secure communication and quantum networks.At SpaceChain Foundation, I lead research on the application of blockchain and space technology, as well as champion the integration of both areas through various means. Examples of this application are seen in our synergic use of blockchain and machine learning to analyse Earth Observation (EO) data and the privacy protection of blockchain within healthcare data.What are the developments in satellite technology that we are going to see over the course of the next several years? How will they apply to and directly affect the New Space Economy?Ziheng: This is an extremely broad question that has to be considered on two levels; from government to private-led interests, and from individual to network-connected ventures.During the course of the next several years, we will see a dramatic shift toward satellite technology becoming more accessible to the average person. Developers will also make further advancements and increase efficiencies in innovation, allowing us to make progress in outer space. Iridium and SpaceX have already made giant steps forward in this field. World-wide accessibility of satellite-based networks is the end-goal and we are moving towards that rapidly.All this will help to make the industry more decentralised — one of SpaceChain Foundation’s key value propositions. At present, the space industry is facing barriers to commercialisation due to lack of resources but there is great promise that all this is about to change. These are exciting times for engineers and SMEs alike.Ziheng Xiang was part of the cybersecurity panel at NSE ExpoForum 2019 held in Rome.Can you share more about SpaceChain Foundation’s decentralised satellite infrastructure (DSI) and how the tech behind it will fill a gap in the industry.Ziheng: Our decentralised satellite infrastructure (DSI), aims to build a satellite constellation that is owned by multiple participating entities. Being different from the existing or proposed constellations such as Iridium or Starlink, the DSI is not owned by anyone in particular. A true open-source blockchain network, our DSI will have different parties contributing to the operation and maintenance of it. Participating satellites will be able to receive information and tasks through its gateway which is essentially a blockchain registry.One of the most integral parts of blockchain is its mechanism of reaching a consensus among its nodes. We are using this concept to make our DSI to be information-synchronized and record-trackable. The participating satellites will be able to view, share and relay the relevant information. It’s a way of building trust and automation across the space technologies industry.You were a mentor at the ESA’s PhiWeek bootcamp in 2019. Could you share with us more about that?Ziheng: The PhiWeek Bootcamp is hosted by the European Space Agency (ESA) in the framework of Phi-Week. It was essentially a workshop for participants to collaborate on innovative ideas for space technology.SpaceChain Foundation’s CEO Zee Zheng and I were invited to fill the role of mentors to create a buzz around the way in which blockchain could be used in space. It was a very lively event that saw us sharing our own technologies, providing advice as well as carrying out discussions on certain industry topics.I think that the presentation Zee and I gave was inspiring. There were a few participants that showed interest in working with SpaceChain Foundation after the workshop was over.I was also flattered by some of the participants who provided feedback that my use of terminology and command of the subject matter was engaging!Ziheng Xiang at ESA’s PhiWeek Bootcamp 2019 explaining the involvement of blockchain in space.How do you see blockchain technology integrating with the space industry over the course of the next several years?Ziheng: I definitely see lots of potential in this field. That being said, we are going to have to wait a while for heightened efficiencies and security improvements across the industry.Blockchain plays an integral role in bringing finance and affiliated use cases to the space industry for commercialisation. I think it is the most important driving force for advancements in blockchain within the industry.We also require solid application scenarios where blockchain plays a pivotal role instead of a contributing one, and that is something we are working on now.What excites you the most about the space industry?Ziheng: Where do I start? I am extremely proud to be part of this exciting industry. Imagine how amazing it would be to discover and explore even a trillionth of the Universe? I know what we tackle on a day-to-day basis may seem unrealistic and far-fetched, but I always reflect on how far we have come.I think the industry also makes us less egocentric, we are merely drops in the mighty ocean. Acknowledging this is both valuable and humbling.How has your experience working with SpaceChain been so far?Ziheng: I never thought I’d say this of anything, but it’s even better than playing video games!On a serious note, the ability to contribute and make a change through such an amazing platform makes me extremely content. I also think that we will reach great heights as a team in the foreseeable future.Check out our other interview series with SpaceChain COO Alessandra Albano and Fossa Systems CEO and co-founder Julian Fernandez.You can connect with Ziheng and the rest of our team as well as keep up-to-date with all of SpaceChain’s developments via Twitter and subscribe to our newsletter on our website for our latest news.Of Satellites, Bootcamps and Video Games was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

Covid-19 as seen from Outer...
Image Credit: Unsplash.comThe current global climate has propelled mankind into unprecedented times. Civilisation as we know it has been thrown into uncharted territory with global economies and entire nations scrambling for solutions to a pandemic that doesn’t seem to be relenting anytime soon.While the world awaits a vaccine for Covid-19, leaders have also identified the need for global participation to ensure that sound handling strategies are in place to protect us all during (and from) future outbreaks. A large part of these strategies lie in warning systems for early detection that will allow experts to implement rapid response measures before such incidents become widespread.We take a look at the pivotal role that satellite technology and Earth Observation Data (EOD) can play in the future mitigation and even prevention of such an outbreak, potentially saving the World from the wide-spreading effects of another pandemic:Image Credit: PixabayLocation is pivotal: To fight against the dreaded virusWe all know about the advantages of contact tracing in the fight against the dreaded virus. Governments have been quick to recognise the importance of leveraging technology to find out who went where and when after contracting Covid-19. Out of these three areas, the ‘where’ seems to be the most important when it comes to reducing the exponential spread of any disease.Satellite imaging takes this form of tracking to a whole new level. According to a scientist at the Institute for Disease Modeling in Seattle, tracked geospatial data (that can be extracted from satellite surveillance and images) provides specific characterisation of disease transmission, risk factors and forecasts of pathogen prevalence.This essentially means that through expert modelling and understanding of key data points, industry experts are able to monitor places where specific diseases are more likely to emerge due to their risk-factors. Areas where human beings have direct contact with wildlife are fertile grounds for Zoonotic (animal to human) diseases — often occurring when there are human-initiated changes to landscapes. An example of where satellite data can help is to identify such areas and monitor them closely from outer space to take preventative steps towards the occurrence of transmissions.Image Credit: Unsplash.comContainment is key: Pandemic status may have been avoidedIt is a foregone conclusion that several major powers failed to take the swift action necessary to contain Covid-19, leading to negative economic and health impacts with grave implications. That said, the necessary reliance on satellites has already been embraced by certain nations during the course of this disease.Contextualised data and geographical insights through technologies such as geofencing, GPS trackers and sensors have been increasingly acknowledged as being able to assist in the planning of health resources and responses in the case of a pandemic. An example of this was seen recently in Kerala, India, where after cases of the virus were reported, primary and secondary contact tracing was collated through geo-mapping that allowed authorities to respond in a timely manner. This could have been one of the main contributing factors to the nation’s low rates of contraction during the early stage of the disease.China also benefited greatly from the utilisation of satellite technology during the course of this pandemic. This was particularly seen in the government’s servicing of remote areas in Wuhan and Shantou. Telemedicine facilities were provided to patients in rural areas with the help of real-time imagery of patients that were then transmitted through a satellite moderator and processed to the communication satellite platform. This information was then sent back to the control centre.There is no doubt that this is not the last time the world will experience a pandemic. The way in which it will be handled, however, will differ greatly through data and surveillance techniques bolstered by advances in technology. The success of leveraging observation data from outer space will rely heavily on a concerted collaborative approach between the space industry as well as government bodies to ensure that the world learns from its mistakes and handles future outbreaks in a timely and efficient manner.Lessons learned: Covid-19 a catalyst for rapid digitalisation of healthcare industryImage Credits: FreePikIf one were to look at one positive effect that the pandemic has had on the world, it would be that it has brought about an urgency for governments and private enterprise to be operationally and technologically ready for any future phenomena of this magnitude. Through these tumultuous times, one thing that the world can be unanimous on is that the collation and analysis of data is critical in both the prevention and mitigation stages during such moments of crisis.Companies such as Healthwave are setting out to change the way medical professionals and patients share insights and exchange knowledge to help shape the way that healthcare is delivered. Their central mandate, which was particularly pertinent during the pandemic, is to essentially help achieve efficient and sustainable systems change, especially in healthcare settings where attempts to utilise patient experience data have often failed to gain traction.One roadblock experienced when collating data is that it is often an expensive exercise, taking up considerable resources due to their complexity and expert manpower required during the analysis stage. That being said, the digitalization of healthcare models has helped to offer professionals in the field with readily accessible data, gathered by an uptake in social media use as well as dramatic increase in internet usage during this period. It is no doubt that this data can function in tandem with that extracted from EO platforms to advance the healthcare industry forward and allow us to be better armed for any future pandemic of this nature.We’re extremely excited about SpaceChain Foundation’s ongoing contribution to the space observation sphere, with our company being touted by Elecnor DEIMOS as key enablers of a more robust EO data commercialisation platform. Our technical and strategy teams look forward to adding further value to the industry through our collaborations with organisations, such as the European Space Agency, and create a safer environment through advancements in technology.You can connect with SpaceChain as well as keep up-to-date with all of our developments via Twitter and subscribe to our newsletter on our website for our latest news.Covid-19 as seen from Outer Space: How Satellite Imaging may Prevent the next Pandemic was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

How the New Space Economy i...
Image Credit: PixabayWhen it comes to the potential for businesses to expand through the evolving space economy, the sky is literally the limit.Global business leaders have already begun to mirror this sentiment by pouring considerable resources into the outer space arena. Founder and CEO of Amazon billionaire Jeff Bezos, for example, is already investing more than USD one billion per year into his space transportation firm, Blue Origin. Initiatives like this will only increase participation in the sector, advancing the New Space Economy over the course of the next several years.We take a look at this playing field, touted to be worth one trillion USD by the end of 2020, exploring three major areas that will be instrumental in changing the face of multiple industries over the course of the next several years.Internet 2.0: Unrivalled Global AccessImage Credit: PixabayIt is an unfortunate fact that the World Wide Web does not serve the entire global population. More than half the world is still unconnected to the internet due to infrastructural as well as financial limitations in several rural areas.Private enterprises have taken on the challenge of bridging this gap in the foreseeable future with companies like SpaceX and Amazon setting out to launch a constellation of internet-beaming satellites. This will expand the reach of the internet to a large proportion of the population that lives in areas without the right infrastructure in place. It will also mitigate some of the issues in connectivity/outages that the internet has to grapple with (due to technological advances in satellite transmissions) as well as reduce costs for the end consumer.There is also the issue of the Earth eventually running out of space to store data. Data farms require physical real estate to store the troves of information that we produce daily, creating a need for developments (already in the works) to create a robust internet storage programme in outer space.AI and Beyond: No Longer the stuff of MoviesImage Credit: UnsplashWhen it comes to the space industry, artificial intelligence (AI) continues to be a tool that businesses find invaluable to create efficiencies and develop a competitive edge over others. Trained over time, AI models have proven to become highly skilled at executing specific tasks.Earth exploration data, for example, is an invaluable tool for both governments as well as private enterprises to accumulate crucial data. Advances in Earth-imaging data will increasingly provide vital insights to help in the calculation of macroeconomic activity, accurately measuring migrant flows and the impact of climate change. The role of AI in the process will play a vital role in the extracting of such information and then appropriating this data for a variety of applications and services.In order for the above-mentioned data collected to remain authentic and verifiable, the industry will see a heightened increase in demand for integrity verification software — an area that SpaceChain is currently addressing through its distributed ledger technology.Fintech’s New FrontierImage Credit: UnsplashThe global financial industry’s resistance to technological advances (due largely to regulatory and security factors) has been changing rapidly in the last few years. The increased adoption of new technologies to facilitate this shift has been fuelled largely through growing efforts by service providers to strengthen overall security across their respective platforms.When it comes to security, the blockchain world has provided both consumers and enterprises with heightened reassurance through various decentralised platforms. This is one area that SpaceChain is particularly excited about, with our very own industry-first blockchain hardware multisignature wallet technology being launched into outer space in December 2019.The launch was a first step in introducing a crypto wallet that will mitigate hardware threats associated with the hacking of fintech applications. It will cater to high-dollar clients, custodial services, exchanges, and enterprise customers — providing for an all-round secure experience through a truly innovative platform in outer space. You can read more about the science behind our infrastructure here.What does all this mean for businesses? The more people connected globally (through higher internet adoption) will translate to larger potential target audiences for businesses, elevated workforce figures as well as greater efficiency across the board. There will also be an increase in employment across the space industry to facilitate advancements through AI innovation, with heightened demand for data experts as well as analysts. The fintech industry will also slowly but steadily move towards bolstering security through decentralised platforms in outer space.Keep up-to-date with all of SpaceChain’s developments via Twitter and subscribe to our newsletter on our website for our latest news.How the New Space Economy is Going to Change YOUR Industry was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

Technical Summary of the CR...
Over the past year, the SpaceChain Technical Team has been focused on creating and launching a Bitcoin multisig payload to the International Space Station (ISS). This payload will demonstrate new levels of cybersecurity for transactions and new paradigms in asset custody.In a standard terrestrial blockchain transaction, one private key is used to complete a transaction which is then broadcast to the network. If that private key becomes known by a malicious entity, all of the funds can be lost. Multisig (multisignature) technology requires more than one private key approval in order to authorise a transaction, rendering the transaction vastly more secure than standard single-signature methods. Furthermore, multisig mechanism provides an effective way of managing accounts/assets that are jointly held by multiple parties. The SpaceChain implementation adds the remoteness and security of low-Earth orbit infrastructure to multisig to create something entirely new.A SpaceChain multisig transaction looks like this: a user creates a space multisig wallet and then initiates a transaction. Subsequently, the transaction is approved with his/her private key. The transaction is then sent up to the low-Earth orbit infrastructure, in this case the ISS, and the payload there approves the transaction with the private key that is generated and stored there. The transaction is then sent down to be broadcasted to the wider network to be included in the blockchain.With the SpaceChain payload, it is highly improbable that an attacker can gain physical access to the device, since it runs in orbit around the earth. In addition, the measurement, control and data transmission of the space payload uses the aerospace-specific encryption protocol, which makes the data very hard to be decrypted. Our payload also adopts the hardware architecture dedicated for the aerospace industry, increasing the difficulty of cracking due to the vast difference compared to terrestrial hardware. Furthermore, the private keys are only generated once after our bitcoin multisig payload is installed in the ISS. In addition, these private keys are stored in the bitcoin multisig payload which cannot be accessed by either SpaceChain or any other terrestrial parties. These processes make the transaction much more secure because it creates additional barriers for an attacker to overcome.The SpaceChain bitcoin multisig payload facilitates transactions and is not a full archival node meant to store all the transactions starting from the Bitcoin genesis block. This is a demonstration of cold storage multisig capabilities being extended to the low Earth orbit, the ISS and the new space economy.Technical Summary of the CRS-19 ISS Mission was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

SpaceChain AMA with Zee & J...
SpaceChain AMA with Zee & Jeff — Aug 28, 2020On Aug 28, the community came together on SpaceChain’s telegram channel to ask CEO Zee Zheng and CTO Jeff Garzik questions. We have compiled the AMA here from our SpaceChain English Community Telegram Group. Thank you for your participation.1. Can you outline the goals and activities for the rest of 2020 and early 2021?Zee: For SpaceChain, 2020 started with very strong momentum. Our ISS (International Space Station) launch last December helped validate our technology. We gained a lot of traction and recognition from our customers and partners. Unfortunately, the COVID-19 pandemic happened and there were some plans we had to pause or delay. However, we are still going ahead really strong. We are expecting another two launches with SpaceX vehicle in the next 9 to 12 months. We are also kicking off a couple of other blockchain and space projects with European Space Agency, Innovate UK and Enterprise Singapore. So stay tune.2. What are a few challenges SpaceChain is facing?Zee:We are leading the industry to explore the integration of blockchain and space technologies, so there is a lot of education that needs to be done. But, we are glad that we have made a lot of progress in that area. Last year, we collaborated with Satellite Applications Catapult to host a blockchain satellite education workshop in Oxford. And this year we did another workshop with Singapore Space Technology Association during GSTC 2020. It is exciting to see an increasing number of people who are interested in what we are doing.The space industry is very traditional and generally slow, while the blockchain industry is growing at a significant rate. To coordinate resources from both industries have been a challenge. We have been working with top institutions in the space industry and truly gained a lot of help as a startup.We have an awesome team that achieved a lot in the past three years, and we are looking forward to growing bigger and bigger. It has been difficult finding technical talents that understand both space and blockchain technologies. If you do know of anyone, do contact our admin.3. One thing I think you guys can improve on is promoting SpaceChain using social media and YouTube influencers. How are you guys getting the word out for this amazing project?Zee: Thank you so much for the advice. We have been doing AMAs, blog posts and social media campaigns frequently. And we are quite active on Twitter. Please follow our Twitter account at https://twitter.com/SpaceChain.4. How are you guys coming along for new exchanges? Out here in the U.S., we have no access for purchasing SPC tokens.Jeff: We are investigating what it takes to connect our token to Uniswap and other DEX exchanges for wider token access. I think plugging the SPC token into DeFi exchanges, and loans and other products will help with that.5. Blockstream recently sent bitcoin to an ex-NASA astronaut (on Earth) from space. So how is SpaceChain the first?Jeff: Our transaction was first, but we could not publicize it for several weeks.Zee: It is also different. The transaction we did was signed by an actual hardware that is installed inside the International Space Station. However, what Blockstream did was to utilize a satellite to broadcast blockchain information.6. Are you building a constellation of satellites? Isn’t it similar to what SpaceX’s Starlink is doing?Zee: We are not building our own constellation. However, we wish to work with other space companies to build a constellation that will be a decentralized infrastructure.Jeff: The Decentralized Satellite Infrastructure (DSI) is a mesh network in space. A blockchain registry is used to store public keys that enable satellite encryption in the network. This provides an economic, authentication and governance layer for any satellite owner to join the network as a node. This also allows multiple different types of satellites to form a single uber constellation, enabling multiple payloads on multiple satellites with multiple owners and tenants.The satellite industry has been single owner, single payload and single tenant for decades, and now that is changing. The DSI working group connects with launch partners, satellite manufacturing partners, and customers, and brings them all together. Users use the network by sending a request to a satellite via the blockchain enabled mesh network. Blockchain token payments are sent alongside the payload request, paying the satellite owner for their time.7. When can coin-related companies and ordinary people store BTC, ETH, and SPC in the space wallet?Zee: It is already happening. Like I mentioned earlier, we are having two SpaceX launches in the next 9 to 12 months, made possible by our exchange and wallet partners. For the last launch, we focused on Bitcoin. For future launches, we are going to expand to more blockchains and tokens, such as ETH, standard ERC tokens, and stable coins etc.8. Coin exchange hacking occurs frequently. Do you think the hacking problem can be solved by using SpaceChain’s space blockchain technology, which has a low transmission speed but high security?Zee: Hacking is one of the biggest threats for cryptocurrency. However, it is a common misunderstanding that “bitcoin was hacked”. It is wrong. Bitcoin was operating as it was designed, and it was always the people that do not manage it well that causes the cryptocurrency to get stolen. We are using our multisignature space technology to reduce human errors, provide longer time for responses and trace funds, and also offer an alternative method to transmit data when there is a critical or a large transaction to be done.9. How can we start building on SpaceChain’s technology and accessing the nodes to build our own apps? What is the process like and how does token utility come into play?Zee: We are releasing a SpaceChain hardware board for development. There will also be developer guideline released on GitHub. Our marketing team is working hard on preparing all the essential materials that you need for development and connecting with SpaceChain’s technology. Please follow our social channels for more details.10. What do you think are the advantages of blockchain in space than on Earth?Zee: There are still many places that do not have land infrastructure. And, blockchain in space can help as it is accessible through satellite infrastructure.* Note: This compilation of AMA questions & answers have been carefully revised to improve the grammar and readability.For more the latest updates, follow up on our social channels or subscribe to our newsletter at https://spacechain.com/subscribe.SpaceChain AMA with Zee & Jeff — Aug 28, 2020 was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

The Multisignature Wallet: ...
Photo by Shane Avery on UnsplashWith the global digital economy advancing at breakneck speeds, one of the most significant issues that innovators have had to grapple with is that of security. No industry is immune to the threat of cybercrimes, spawning entire teams of policy makers and regulators who are constantly creating new ways to remain one step ahead of financial fraud in today’s connected world.One way to combat this problem is by using the multisignature wallet — a secure storage medium for managing digital assets such as cryptocurrencies. Essentially, a multisig wallet adds layers of security to protect your digital assets, just like a joint bank account would in the physical world.Here are three reasons why each and every one of you should sign up for one moving forward:Keeps your digital assets more secure with multiple signaturesMoving back to the issue of cyber security, hackers of today are using sophisticated means of social engineering such as phishing to coerce their targets into providing their passwords for criminal purposes. This risk is highly negated when more than one signature is required to access your funds.The multisig wallet requires two or more sign-offs for any transaction to take place, reducing risks of theft or misappropriation considerably. Security is also enhanced by increasing the number of signatures.Gives you access to your funds even if you lose one passwordThere is no central repository of passwords for digital assets — this essentially means that with a single authentication account, no one can help you retrieve your password if it’s lost. According to the Wall Street Journal, a fifth of all Bitcoin (approximately US$20 billion as of 2018) is lost permanently. The multisig wallet wants to solve this issue.Using a simple analogy, say you sign up for a two-of-three signature wallet (where a minimum of two signatures are necessary to access the account), you may decide to keep one password on your computer, one written on a piece of paper in a safe deposit box and the third in your mobile phone.If you lose either your phone or computer, you can still access you funds with the other two keys kept in separate locations securely. And, if someone steals your phone, he/she will also need access to your computer or the safe deposit box to log into your account — the probability of this is highly unlikely.Protects you from security threats and facilitates better business processesCompanies that transact heavily in digital assets, for example, may not want one board member to have sole rights of funds at any given time. If they sign up for a four-of-five wallet, a board with five members will need the majority (80%) to agree before any financial decision is made. The adoption of such wallets will reduce the chance of internal fraud and disputes considerably.Though it is unlikely that the private keys of four of those five wallets are stolen, this undesirable situation may still take place, leading to the theft or misappropriate use of the wallet.Image by Free-Photos from PixabayTo further improve the security of a multisig service, SpaceChain uses a space node as one of the parties to approve a multisig transaction. The risk of physically destroying the space node is reduced greatly as it runs on orbit around the earth. In addition, the measurement, control and data transmission of the space node uses the aerospace-specific code encryption protocol and communication band, making the data hard to be decrypted.The space node also uses the hardware architecture and operating system tailored for the aerospace industry, which increases the difficulty of cracking. Thus, space nodes are one of the best choices for third-party nodes for multisig transactions.On December 5, 2019, SpaceChain launched a testbed for a two-of-three multisig transaction authentication in space aboard a SpaceX Falcon 9 rocket from the Kennedy Space Center. The payload was sent to the International Space Station and is the first blockchain hardware installed there. Read more here.Upon activation, the payload will demonstrate the receipt, authorisation, and retransmission of blockchain multisig transactions. SpaceChain’s implementation adds the remoteness and security of space infrastructure to blockchain technology to lay the foundation for a new generation of products built on its technology.Follow us on Twitter for more updates.

SpaceChain Executes First M...
Milestone advances SpaceChain vision of creating a decentralized orbital constellation for fintech applications and business transactions as part of the ESA Kick-start Activity programHARWELL, United Kingdom — August 18, 2020 — SpaceChain UK Limited (SpaceChain) today announced the successful execution of the first multisignature blockchain transaction in space, marking the completion of a significant milestone supported by the European Space Agency (ESA) Space Solutions as a Kick-start Activity. The transaction was performed by SpaceChain co-founder and CTO Jeff Garzik. The transaction slip has been made available for public viewing.In December 2019, SpaceChain launched a testbed for blockchain multisignature authentication service to the International Space Station (ISS) aboard a SpaceX Falcon 9 rocket via Nanoracks.The multisignature transaction was delivered through a blockchain hardware installed on the ISS — a powerful onboard computer supplied by GomSpace that was designed for state-of-the-art data processing.The ISS demonstration was also made possible by Nanoracks and its Space Act agreement with NASA. Nanoracks provided the necessary expertise and technology through its Nanolab platform, creating an efficient way for space utilization that is conducive for space research and testing.“Executing the multisignature transaction in space encapsulates our continuous efforts in building out an open-source blockchain-based satellite network that is secure and immutable,” said Jeff Garzik, SpaceChain co-founder and CTO. “SpaceChain aims to be the one-stop solutions provider for the integration of blockchain and space. As we continue to identify more use cases for blockchain-based satellite networks in space, we hope to bring blockchain to mass adoption.”SpaceChain has conducted stringent testing to ensure robust and reliable connectivity between the blockchain hardware in space and land-based infrastructure on Earth. With the added remoteness and security of space infrastructure, new digital products can be built upon the technology and use cases identified for digital banks and fintech companies.Upon initiating the multisignature transaction, the encrypted data was transmitted securely through a ground station to the ISS, which holds a private key to verify and approve the transaction.“It’s an incredible honor to be selected by SpaceChain as the main supplier for its blockchain hardware wallet. The success of the first multisignature blockchain transaction in space demonstrates the onboard computer’s capabilities in supporting decentralized constellations in space with unparalleled data processing performance,” said Niels Buus, CEO of GomSpace. “This milestone has built momentum for the use of space systems and services in the commercial market, and we are excited to further integrate our innovative technologies to help SpaceChain achieve its goals in space and beyond.”SpaceChain’s added security and resilience for integrated space and blockchain technology will provide a solid base for building out future solutions, as it continues to explore and develop applications based on its platform in collaboration with reputable and best-in-class alliance partners.About SpaceChainSpaceChain fosters decentralized infrastructure for the New Space Economy.

The Moon, Mars and Beyond: ...
In our latest series of interviews with space and blockchain industry thought leaders, we caught up with SpaceChain’s Chief Commercial Officer and UK Director Nick Trudgen to tap into his experience and find out about the future of the space and blockchain industries.What is your professional background and your role at SpaceChain Foundation?Nick: I come from a background in business development, law, and international investment. Prior to joining SpaceChain Foundation, I led the international department for a multi-national law firm in both Beijing and Shanghai. I was responsible for their international strategy, and establishing and maintaining relations with the firm’s partners as well as clients in the US, Europe, and Middle East. I also had the honor of setting up the firm’s Space Group, the first dedicated space law department within a mainland China law firm.Being part of the founding team at SpaceChain Foundation, I’ve been leading the company’s international business development. I am responsible for establishing partnerships with private space companies and government agencies. As Director of SpaceChain UK, I also manage our team there, being the conduit for communication between the UK office and the Singapore and Beijing offices, maintaining regular contact with the relevant stakeholders in the UK such as the UK Space Agency, Deimos Space UK, and Satellite Applications Catapult.I’m also responsible for managing SpaceChain UK’s technology development projects with the European Space Agency, and Innovate UK, and coordinating the execution of such projects with our various partners.How does the UK office differ from the company’s other global offices? Are there different areas of focus within each center?Nick: It goes without saying that each international office has a specialisation or area of focus that supports the company as a whole.Our team in the UK office, based at the Satellite Applications Catapult at Harwell campus, focuses on space and blockchain technology research and development for the European market. The SpaceChain UK team is made up of well-respected engineers in the fields of software development, quantum communications, aerospace etc. The team works closely with the European Space Agency and a number of other partner organisations and companies to develop innovative technology solutions for the European space and blockchain market.The team in the Beijing office manages technical operations within mainland China, while the team in the Singapore office is primarily responsible for handling the financial, human resources, and technical project management for the company. They also focus on developing marketing and media campaigns as well as supporting SpaceChain’s US missions such as our launching of a payload to the ISS in December 2019.We understand that you’re fluent in Mandarin. Tell us a bit about how this has helped the company collaborate across UK-China trade and investment interests.Nick: This is one question I get asked a lot. I must say that having a grasp of a foreign language as well as understanding the nuisances of a whole new culture is always key to immersing oneself fully into the country’s work environment.The space industry is particularly international, with most companies and organisations collaborating with partners from across the globe and with supply chains that stem anywhere from the UK, US, China, Singapore to Europe.SpaceChain Foundation itself has a multicultural team, and being able to speak Mandarin is extremely useful when building strong relationships with partners and stakeholders from around the world. China is becoming increasingly important as a center for innovation in both space and blockchain sectors, with world-leading initiatives such as the Tiangong space station, Chang’e lunar missions, Beidou GPS, and the announcement of the digital Renminbi, national blockchain network, and China’s leading role in blockchain-related patents at the WIPO.Having a sound knowledge of the Chinese language definitely provides a window into this exciting market and enables SpaceChain and our international partners to collaborate more effectively.Nick at the Kennedy Space Centre in Cape Canaveral, Florida, viewing SpaceChain’s launch to the International Space Station.How is the space and blockchain industry scene in the UK in terms of adoption and advancements?Nick: When it comes to space technology, the UK is one of the world leaders, especially in the manufacturing of small satellites.Surrey Satellite Technology (SSTL), for example, is a pioneer in the development of small satellites using commercial off-the-shelf (COTS) components and has achieved a range of world firsts. These include:The first modern microsatellite with in-orbit re-programmable computersFirst modular 50kg microsatellite designFirst satellites for South Korea, Portugal, Chile, Algeria, and NigeriaFirst microsatellite using GPS for onboard orbit determinationFirst microsatellite to take multispectral earth imagesFirst use of propulsion on a nanosatelliteFirst Galileo positioning satelliteFirst in-orbit demonstration of space debris capture (most recent).Looking towards the future, SSTL is planning the Lunar Pathfinder, a relay satellite for lunar missions that will be developed alongside the European Space Agency. We have a thriving space ecosystem centered within the Harwell space campus near Oxford, where the ESA European Centre for Space Applications and Telecommunications is located.The UK also played a crucial role at the beginning of the space age, through Goonhilly Earth Station’s role in broadcasting the Apollo moon landings and communicating with Telstar. Looking forward, it is also playing a key role in the development of the New Space Economy, with British company OneWeb building a mega constellation of internet satellites in low-earth orbit. The UK is also leading the way in Europe in the development of commercial spaceports, with horizontal and vertical launch locations currently being planned at Spaceport Cornwall, Space Hub Sutherland, and the Shetland Space Centre.In your opinion, how is the blockchain industry developing and where will it be in the next 10 years?Nick: After many years of hype, the blockchain industry is finally reaching a level of maturity where we are seeing a number of real-world applications across various sectors.When it comes to the space industry, SpaceChain and several other companies and organisations are developing innovative DLT solutions that leverage the potential benefits of blockchain technology. These cover the areas of transparency, efficiency, privacy, and resilience. It is definitely promising to see both NASA and the European Space Agency supporting the development of blockchain and DLT applications.NASA, for example, recently provided funding for the development of autonomous spacecraft that utilise blockchain to minimise human involvement. The European Space Agency has also provided funding for research into how blockchain can be used to verify the integrity and provenance of Earth Observation data.On the private enterprise front, companies such as ConsenSys Space, for example, is developing a project called TruSat which will utilise an open-source system to create a trusted distributed ledger of satellite orbital positions to help track space debris. In the US, SIMBA Chain is building a blockchain-based secure messaging and transaction platform for the Department of Defense.Over the next 10years, we are likely to see increased adoption of DLT across the space sector supply chain, as well as efforts by the ITU, IEEE, ISO etc to create common standards and protocols to ensure the security of distributed ledger technologies.What are the obstacles currently experienced across the blockchain industry?Nick: Adoption of blockchain technology — on a large scale — faces significant technical and regulatory challenges.In terms of its technology, there are issues with scalability and lack of interoperability. Also, due to blockchain’s distributed nature, transactions can be slow and inefficient, factors that limit its potential uses in real-world applications.The main regulatory challenges relate to issues of jurisdiction. This is because blockchain’s distributed ledger can cover many locations around the world, making it difficult to establish which jurisdictions’ laws and regulations apply. Various countries have faced difficulties in applying the existing regulatory framework, in particular in relation to digital assets and fundraising.There are also significant challenges in relation to privacy and data protection, with many arguing that blockchain technology is incompatible with the EU’s General Data Protection Regulation. For example, blockchain’s core attribute of enabling peer-to-peer transactions without the need for a central intermediary conflict with the central tenet of privacy law and data protection, which requires the safeguarding of users’ privacy and data.SpaceChain CCO and UK Director Nick Trudge at the World Internet China Conference 2019.What excites you the most about the space industry?Nick: The two things I’m most excited about are space tourism and the development of the lunar economy.It seems like the technology is already in place to make space tourism a reality. Virgin Galactic’s SpaceShipTwo recently completed its first flight over Spaceport America and the company has already sold out of tickets for its initial round of flights, with each trip costing 250,000 USD.There is clearly a big demand among potential space tourists and in the long term, space tourism will likely evolve into point-to-point suborbital space travel around the globe. Richard Branson has already spoken of Virgin Galactic’s plan to explore point-to-point travel in partnership with Boeing.Various countries are also planning to explore and establish long-term settlements on the moon, with the US Artemis, China’s Chang’e, India’s Chandrayaan, and Europe’s Moon Village among some of the government led lunar missions likely to make significant progress over the next decade.Various private companies such as ispace, SpaceIL, and OffWorld are also developing technologies needed for exploration and utilisation of lunar resources. It is likely that the development of the lunar economy will be carried out initially by robotic systems, with the extraction of lunar water to be used as fuel being the first crucial step in creating a sustainable lunar economy.How has your experience working with SpaceChain Foundation been so far?Nick: I have been extremely fortunate to be part of the SpaceChain Foundation team, which is made up of individuals who are genuinely passionate about their work.We are a very international group, with team members based around the world across Singapore, the UK, China, and the US. It’s extremely important that the space industry fosters international collaboration, as space missions are complex and require support from as many partners as possible. This is especially true for deep space and lunar exploration, which will require all nations to commit to cooperation and sharing of technology and resources.SpaceChain Foundation, with its multicultural and international background, is a good example of the type of company which will help push humanity forward on our voyage to the moon, Mars, and beyond.Check out our other interview series with SpaceChain Foundation COO Alessandra Albano and Fossa Systems CEO and co-founder Julian Fernandez.You can connect with Nick and the rest of our team as well as keep up-to-date with all of SpaceChain’s developments via Twitter and subscribe to our newsletter on our website for our latest news.The Moon, Mars and Beyond: Outer Space Tourism and Converting Water to Fuel was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

Image Source: UnsplashIn the midst of all the awe and wonder surrounding space travel, enthusiasts often ignore one of the greatest marvels of the industry — the underlying science that allows human-made objects to reach outer space and stay there.Sci-fi movies also tend to sensationalise the earth exploration sphere, focusing more on fiction (that sells more tickets) than scientific principles to advance their plots further. How do satellites dock in Earth’s orbit instead of continuing to fly into outer space? Why don’t satellites fall back onto earth? How does a satellite safely dock with another if it’s travelling at such fast speeds?Gravity (2013)How Satellites Reach Space and Stay ThereSatellites depend largely on balancing speed and gravity to reach their desired orbit. In short, they maintain their position by locking into speeds that are fast enough to defeat the downward pull of gravity.To reach outer space, a rocket (the vehicle that carries and drops off a satellite in space) must accelerate to at least 25,039 mph (40,320 kph) to completely escape Earth’s gravity. This amounts to moving at a speed of over 10,000 metres every second! It should be noted, however, that satellites need to maintain a balance in velocity so that they can orbit above the Earth. It is this very balance that prevents them from flying in a straight line off into space or falling back to Earth.In order to achieve the above, they need to travel at a speed that will facilitate orbital velocity — the term used to describe the balance between gravity’s pull on the satellite and the inertia of the satellite’s motion (the satellite’s tendency to keep going).A satellite orbiting closer to the Earth, for example, requires more velocity to resist the stronger gravitational pull. This considerably lower speed that satellites travel at is generally around the 17,000 mph (27,359 kph) mark, allowing them to orbit at an altitude of around 150 miles (242 kilometers) from the Earth’s surface.Image Source: PixabayWhen Two Satellites MeetThe term space rendezvous is used to describe the process whereby two spacecraft (one of which is often a space station) intentionally approach each other at a very close distance. This requires a precise match in orbital velocities and position vectors of the two objects, allowing for the entities to maintain safe distances.A space rendezvous is often accompanied by the practice of docking, whereby both entities come into physical contact with each other to create a link. This is an extremely delicate and dangerous procedure with little room for error — due to the high speeds at which satellites travel.SpaceX leveraged this process in the docking of the Dragon space capsule containing the SpaceChain blockchain hardware payload when it reached the International Space Station (ISS) in early December 2019. The first technological demonstration of blockchain hardware on the ISS, the payload will be used to demonstrate the receipt, authorisation, and retransmission of blockchain transactions.Keep up-to-date with all of SpaceChain’s developments via Twitter and subscribe to our newsletter on our website for our latest news.Satellites don’t Fly, They Fall: The Science of Keeping Objects in Orbit was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

Decentralised Satellite Inf...
Over the past decade we have witnessed a paradigm shift in the commercialisation of space with a vast array of companies entering the space industry. It is now possible to find service providers for every stage of a space mission, from chip designers and microsatellite vendors to launch providers and ground stations services. Companies from all over the globe are now ready to service space missions. However, the way each mission is designed and executed has not seen the same transformation. Most missions are still single vendor, single purpose, and not networked to other spacecraft, resulting in an inefficient allocation of resources. To get to the next stage of the space industry spacecraft need to have the ability to network together to create collaborative satellite constellations, but there are some technical challenges:A platform-based environment needs to be constructed with trust among various participating parties.Communication among satellites needs to follow a unified standard to enable a flexible and efficient information routing.SpaceChain Foundation aims to target these challenges, building an alliance consortium towards the creation of a Decentralised Satellite Infrastructure (DSI), a mesh-network of heterogeneous spacecraft owned and operated in Low Earth Orbit (LEO) by multiple parties in multiple jurisdictions. Spacecraft may join or depart the constellation at any time via a blockchain registry, as long as the crafts meet minimal economic, technical and regulatory requirements sufficient to ensure the long term health and resilience of the constellation.Blockchain Registry of DSIBlockchain technology supports the backbone of the DSI architecture via a Blockchain Registry. During the registry phase a satellite would certify that it met the minimum operational standards to be added to the network. Once approved the satellite would be assigned a private key and the ability to route and allocate DSI assignments via a smart-contract based blockchain bidding environment, ensuring transparency and trust.Satellite Mesh-network RoutingWith DSI, participating satellites will be able to support secure information transmission between distant parties, served as relays via a new Optical Link routing protocol. The routing protocol development focuses on how relay nodes are chosen for efficient information transmission between two distant satellites, as well as how a robust relay network could be established for the entire DSI network.Current inter-satellite communication is based mostly on RF signals. RF transmission requires a simple hardware setup but offers slow data transmission rates. Optical links, on the other hand, provide high communication speed but also require complicated hardware including source APT (acquisition, pointing and tracking) systems and detection modules. However, for long distance communication in space, optical links have outstanding performance compared with RF, making it a necessary component for future development of satellite technology. Thus, we aim to develop an effective optical inter-satellite link model which is easy for adaptation to a traditional satellite company.Hardware and Software StandardsSpaceChain Foundation will collaborate with partners and manufacturers to enable satellites to participate in DSI freely by developing standards related to:Processing power: Minimum processing requirements will be applied to the participating satellites to enable activities under the Blockchain registry, smart contract ‘bidding’, mesh-network support and routing protocol for the DSI.Data storage and encryption: Minimum storage capacity will be established for storing and synchronising DSI assignments, as well as uniform encryption standards.Optical link bandwidth and APT systems: Minimum bandwidth for optical links and minimum hardware for APT systems will be established to maintain robust connectivity and throughput.To enable high-speed communication, DSI would introduce optical communication links between participating satellites in addition to traditional RF communication, supported by an acquisition, pointing and tracking (APT) system. Mesh-network and routing protocols would support valid communication between satellites with RF and optical links via certain relay nodes.Collaboration with Geosynchronous Satellites and Deep Space ResearchInteroperability with geosynchronous satellites (GEO) as well as external constellations is one of the core development focuses for DSI. Although the majority of DSI satellites will be participating members of the LEO mesh-network, connections with GEO satellites and other unaffiliated external constellations would make a more robust network, as well as providing a relay for spacecraft operating in High Earth orbit or deep space.With improved communication speed among various nodes, DSI satellites could serve as receivers for information transmitted back from satellites in deep space. A potential collaboration could be established by sending deep space exploration satellites with optical communication modules, sending back information to DSI satellites or relay the information from other deep-space satellites received by its RF module.Decentralised Satellite Infrastructure was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

SpaceChain Foundation is excited to announce that our blockchain hardware embedded with the multisignature wallet technology has been installed on the International Space Station (ISS)! The installation was conducted by astronaut Jessica Meir, who is also a marine biologist, physiologist, and more recently, the participant of the first all women space walk.https://medium.com/media/3f5e2546ebf776acca7d511bb5ee9839/hrefOur second-generation blockchain hardware (Fig. 1) is housed in a 1U NanoLab (Fig. 2) that is designed by Nanoracks. Thanks to the modularised features of the hardware, astronaut Jessica Meir is able to easily plug the NanoLab into the research platform via a USB port to power up our hardware. This allows us to send data and command files from the ground station to our ISS hardware, and vice versa. Check out how the full installation was done here.Fig. 1: SpaceChain Foundation Blockchain Hardware — second-generation flight-tested ZYNQ board (IPC-A-610 Class 3), Linux OS, dual ARM Cortex processor, gigabyte ECC memory, and EMI shielding.Fig. 2: A 1U NanoLab module (10 cm x 10 cm x 10 cm). Photo: NanoracksWhy put blockchain in space?In a standard terrestrial blockchain transaction, one private key is used to complete a transaction which is then broadcast to the network. If that private key becomes known by a malicious entity, all of the funds can be lost. Multisig (multisignature) technology requires more than one private key approval in order to authorise a transaction, rendering the transaction vastly more secure than standard single-signature methods. Furthermore, multisig mechanism provides an effective way of managing accounts/assets that are jointly held by multiple parties. The SpaceChain Foundation implementation adds the remoteness and security of low-Earth orbit infrastructure to multisig to create something entirely new.“The integration of space and blockchain technologies has uncovered new possibilities and opportunities and we are very excited about the prospect of working closely with financial service providers, fintech and Bitcoin developers, IoT service providers, research institutions and space agencies in the coming months to further accelerate advancements within the ecosystem,” said Zee Zheng, SpaceChain co-founder and CEO.This opportunity was provided via Nanoracks and their Space Act Agreement with NASA.

The Open-Source Revolution ...
As part of our series of interviews with space and blockchain industry thought leaders, we had a chat with Fossa Systems’ Chief Executive Officer and Co-founder Julian Fernandez about issues around picosatellites, open-source space and the future of the space industry.Fossa Systems is dedicated to the development of open- source picosatellites enabling experimental worldwide IoT connectivity and democratising space. Learn more about Fossa Systems here and check out their GitHub repository.1. What made you decide to set up Fossa Systems?Julian: My interest in space and COTS hardware spans back to 2017 when I started working on femtosatellites (Sub 100g spacecraft). I have also worked on various IoT related projects for remote asset monitorisation. This last experience further taught me the need for remote IoT connectivity.Fossa Systems was initially created in response to the market need for inexpensive and fast solutions regarding worldwide connectivity. Our goal is to democratise access to space and telecommunications as a hardware manufacturer. This means developing inexpensive satellite platforms and operating these low-cost systems.We actually started Fossa Systems as a non-profit project on an online forum in 2018. Back then, we were students and needed a cheap way of getting to space.2. How does a free and open-source mentality contribute to the development of the New Space industry?Julian: Our name Fossa Systems indicates Free Open Source Software and Aerospace Systems. As such, open source is a major part of our business model. We believe it is imperative that we develop space technology in an open manner for the benefit of all.This can be perfectly linked to a successful business model as we are demonstrating with the launch of three satellites to this date. New Space is a rapidly developing and advancing industry where secrecy only constitutes an impediment to the general advancement of the market.3. Tell us more about the FossaSat-1 and FossaSat-2 satellites and their applications.Julian: Having learnt from the design of the FossaSat-1 satellite, which we launched in December 2019, we made improvements to the architecture and developed the FossaSat-2. This new picosatellite platform caters to the current market need for Low-Earth Orbit (LEO) telecommunications constellations and performance-oriented integrated solutions for customer payloads such as radio modules or Earth Observation (EO) sensors.Based on the PocketQube platform, the FossaSat-2 is only 5x5x5cm big, and weighs a mere 250g. Its compact size and weight greatly reduces the current cost for access to space. Plus, it costs under 40,000€ (USD$44,000) for access to a 500km LEO with existing brokers.Both the FossaSat-1 and FossaSat-2 are mainly used for telecommunications and are initially being tested with these payloads. But, they can also be used for other mission specific payloads such as EO cameras. In fact, the FossaSat-2 will be flying the first camera on a picosatellite into space.You can find out more about each satellite here.4. What will be the real-world applications for Fossa System’s work on LoRa technology for the internet of things?Julian: LoRa was successfully tested on the FossaSat-1 satellite that we launched in December 2019. LoRa allows 3€ terminals to communicate with a satellite within ISM band limitations. It truly constitutes a major breakthrough in modulations that will allow the creation of global low-power IoT constellations.We are currently planning on using our future LoRa services for remote asset management and other non-accessible terminals.5. Which partners have Fossa Systems worked with in developing and launching your picosatellites?Julian: Fossa Systems has been mostly funded by Everis Aerospace & Defense, a company of the NTT Data Group. We have worked with various large aerospace companies on the development of our technology and have most recently started working with the ESA Galileo Science Office for flying GNSS receivers on our satellites.6. What are some of the biggest challenges you have faced in building Fossa Systems?Julian: Building a New Space company definitely is not an easy job. It is such a new market and we are always adventuring into unknown territory. Our biggest challenge has already been undertaken with the launch of our first satellite. The next challenge is to establish ourselves as a respected and trustworthy hardware provider in the industry. We are also still studying the challenging possibility of offering services using our hardware in LEO.7. Can you share some of your plans for Fossa Systems for the next couple of years?Julian: Fossa Systems is in the process of registering a more formal commercial division to further advance the professional development of Fossa’s satellites in the growing market. Fossa Systems will always keep its initial values and objectives as a priority. We are opening our office in Madrid in the coming months and are looking to professionalise our production chain to take on more serious contracts.8. How do you see the space industry developing in the short and long term?Julian: With regards to the evolution of satellite size in the industry, we are definitely going to see further miniaturisation and advancement of COTS technology for LEO. I believe large mega constellations do not pose a serious risk to the market we are targeting regarding IoT, but they are starting to pose a serious risk to the cluttering of orbital planes.This year alone we have had three close calls between our FossaSat-1 and one of Elon Musk’s Starlink satellites. The COVID-19 pandemic also poses a serious effect on the short-term investment in satellite businesses (as apparent with the bankruptcy filing of OneWeb), but in the long term, I believe we will ultimately recover.9. Which space technology developments most excite you?Julian: We are very excited about the development of electric propulsion and are actually flying Pulsed Plasma Thrusters from Applied Ion Systems as one of our payloads. We look forward to seeing what electrospray technology brings to the table with regards to in-orbit manoeuvring technology.10. How do you see blockchain contributing to the space sector?Julian: Blockchain has actually been on Fossa System’s radar since its creation. We believe it will have and is already having a significant impact on the way we are able to safely communicate and store data in a decentralised manner. We are starting to see immense progress in this field such as the use of cubesats for carrying out blockchain transactions in space.11. What advice would you give to young entrepreneurs thinking about starting their own space startup?Julian: It is important to have a clear and differentiating goal when creating a startup. There are lots of competitors in the New Space market at this stage, and lots of them have years of experience behind them. Patience and determination is important, but what seems like the most important quality is speed. Clients expect fast turnaround solutions, and in this industry, you have to constantly run to keep up with the rest. In part, this is our philosophy at Fossa Systems which is quite distant to what we see in larger and older satellite hardware manufacturers.12. What are your thoughts about the Decentralised Satellite Infrastructure (DSI) that SpaceChain is leading and developing?Julian: As a hardware manufacturer and service provider, we see SpaceChain’s ideas of creating a DSI completely align with our ideas and values. We hope to be able to work with SpaceChain on implementing and getting their technology into LEO using our platforms.Click here to check out our other interview series with SpaceChain COO Alessandra Albano.Keep up-to-date with all of SpaceChain’s developments via Twitter and subscribe to our newsletter on our website for our latest news.The Open-Source Revolution in Outer Space was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

AMA with Jeff Garzik and Je...
Topic of Discussion: An open-source hardware platform for Direct Satellite-to-Devices CommunicationOn May 28, 2020, Jeff Garzik and Jeff Dionne held an AMA on Reddit.Jeff Garzik is the CTO of SpaceChain Foundation. He is known for being the key Bitcoin core developer who worked under Satoshi Nakamoto for two years. His work can be found in every bitcoin and miner.Jeff Dionne is the CEO of Core Semiconductor. He is known for uClinux, from which most embedded Linux systems are derived, and developing many other game-changing embedded systems hardware and software technologies.Garzik and Dionne have always been passionate about pushing the boundaries of space and blockchain applications; a few of the past projects they have worked on are Linux kernel and Bitcoin Core.They love to share more about their experiences being in their respective industries, such as the formation of the open-source industry, open hardware, fabless semiconductor development, nano-satellites, cryptocurrency, and more.In this AMA, they discuss their development for their latest project — an open-source hardware platform that is capable of providing a downlink to mobile phones and small devices directly from satellites in orbit — all without the use of a satellite dish on Earth or a third-party network.Here are some of the highlights:1. What is in your opinion the best node or process to target when optimising price to performance ratio and having a low digital chip volume? What processes can we expect from the first Silicon running J-Core?Dionne: It’s just my opinion… it depends on the application (maybe you can elaborate). At the moment with that caveat and in general terms, I’d probably say 55nm. It’s a commodity process and every fab offers it. But take that with a grain of salt, to properly answer the question I’d want to know the application but also the gate count, budget and what performance means to you. I’m assuming you’re talking about a general purpose embedded application with a CPU.We’re working on a customer project that has a chance to be the first tapeout for CoreSemi in late 2020. Depending on their volume, we’ll probably target 55nm, but we already have some (not portable) IP blocks in 152nm from a previous design we could leverage.There is also the idea that we might try and do a fully open (right down to the standard cells and IO pads) design that the community could reproduce. That would be 350nm, because shuttle runs are on the order of $10k.The first application processor for J-Core will likely be quad core on 28nm, but that is a ways out yet.2. That large process size sounds a lot like what https://libresilicon.com/ is targeting. Have you looked into them?Dionne: Yes, and also relevant is http://opencircuitdesign.com. Part of the problem with using smaller process nodes in a completely open design is the NDAs that are needed. There are actual fab design rule documents that can be had for older processes… Once the business model of completely open designs has been proven to the fabs, we are hoping the situation improves.Still doesn’t solve the issue that 180nm might be within reach of an open hardware Crowd Supply, but 28nm isn’t really.3. What is the current performance of your GNSS implementation in terms of sample per min, latency and accuracy? Is there room for some more light computation on the current JCore you are using like drone flight control or robot control?Dionne: The released GNSS RTL https://github.com/CoreSemi/gnss-baseband is designed to produce one output from the hardware engine to the host CPU every 1 ms. It’s the task of the software part to turn those raw samples into fix updates (for location). So the answer is updates can be as often as you take outputs from the software tracking loops and run the solution solver. We’ve not yet released the software side, probably that will take a few weeks or a month. We previously used this engine for precise timing, in overdetermined clock mode, and that isn’t in general what the community will want.In a drone application, a dual J-Core SoC on an FPGA is definitely sufficient, a configuration that is basically a sweet spot for size and cost of the chip. If we were to put that on an ASIC, you could use a fairly cheap process and have plenty of DSP capability for flight control etc.Would such a chip, or an FPGA board with a form factor useful for drone/robot control be something you think would be interesting?4. Today’s setup for precision GPS requires RTK, so you end up with additional hardware. People are flying drones or driving robots on RPi, and so the size wouldn’t be a problem for a Turtle board. There is hat for RPi for this kind of application, but they aren’t really open hardware ( https://emlid.com/navio/ ). Just finding which pins emlid use is not obvious… I would think there would be some interest in a high precision drone setup that fit in a RPi format.Dionne: Ok, thanks for the feedback. The receiver board that CoreSemi and SpaceChain put together fits on the Turtle Platform… We intend both of those to go up on Crowd Supply. We’re working on it, and we intend to do it in the next few months, but that has been slow going so no promises just yet.Hearing there is interest definitely helps.5. Did I miss the J32 release? If not when will it be out? Also how can the community help Core Semi?Dionne: Coming up this summer. Software generally takes longer than hardware, J2 is well tested and supported by everything from the compilers to OS and application side, J32 CPU hardware needs that complete package before it can see wide use.If we engage with the community to test and port software to the J32 platform (when released), that will be a great help in getting there. In the meantime, clone our repos, support our Crowd Supply, and support our partner SpaceChain whose support made these releases possible.6. I am interested in knowing why SpaceChain decided to invest in Core Semiconductor when it is less than 6 months old?Garzik: CoreSemi’s team and technology are much older than 6 months. The team has been involved in Linux and open source for 15+ years, and at the time had already developed a clean room implementation of the Hitachi SuperH processor (dubbed “J-core”), with themselves and some of the original Hitachi chip engineers.SpaceChain wanted to help that team revive and market this open source hardware, as a fresh base for a new line of chips that can be used in space as well as on the ground.SpaceChain has an interest in having open source hardware widely used — “with many eyes, all bugs are shallow” — investing in CoreSemi acts as a force multiplier for Spacechain and the whole open source ecosystem, which largely runs on closed processors today. The security value of open source means we can change that.7. How can CoreSemi justify going with J-Core (SuperH) when RISC-V is all the rage? What relationship do you see J-Core having with RISC-V?Dionne: We see J-Core and RISC-V existing in slightly different application spaces. J-Core arguably has better instruction set characteristics for deeply embedded applications (such as this GNSS / Downlink) and RISC-V is designed more as a competitor to ARM.Both cores have the goal of democratizing the space, the differences in design philosophy with J-Core (SHCompact ISA) being more like an x86 with highly encoded, compiler friendly instructions. No one can argue that approach doesn’t have application. IMHO RISC-V is emphasizing clean and simple, directly implemented pipelines. Having both gives us all choice. In fact some of SpaceChain’s engineers are core developers of a well known RISC-V implementation called Hummingbird E203.8. Because of COVID-19 there will be no in-person conferences where you could present J-Core and recent developments.Do you plan to do long form presentations/podcasts where you tell us about what’s next, why things always take longer, what sessions you learned etc?Dionne: Community engagement is important to us. We think given the constraints on in person presentations, the best plan seems to be a series of videos (YouTube and probably lbry.tv). Things do take longer than one imagines or would like, but the reason for that is never problems with the technology.One thing I’d say we’ve learned is that there is no substitute for clean, buildable and well documented releases of the technology that have a hardware platform people can get their hands on. That is different from the pure open source software only model, and it’s a limiting factor for growth of open hardware. So we set out to change that. Our plan to do that is this:Build a production version of the Jx FPGA platform (turtle board) (done)With our partner SpaceChain, develop an application people can use (GNSS, and Downlink for things like IoT command and control, cryptographic hashes for light wallets, etc). Make the ‘hat’ board for that open also (this announcement)Release the RTL (done), and then the software (in progress)Get these kits into the hands of developers so they can build on top of our workBegin publishing videos to show how to do that.Numbers 4 and 5 are obviously one response to the global situation, but also have the benefit of producing artifacts people can work from in the future.9. Garzik, I recall multi-tenant computing on satellites being mentioned. What do you see as use cases where tenants want to run code on satellites?Colour me naive but the only thing that strikes me is access to the sensor data of the satellite but I guess it would be cheaper to just send the complete data down and process it on some normal computer?Garzik: The existing satellite industry model is: one sat owner, one operator (often same as owner), and closed software, usually for a single purpose.With modern software sandboxing, we can open that model up, making a — arguably risky — move to permit customers to upload their software. That’s brand new to the satellite industry, even though it is familiar and boring to the mobile phone and blockchain industries, where multi-app is normal.Opening up the closed satellite industry model is key to making access to space less expensive and more egalitarian.10. Do you have any use case examples where it would make sense to run my code above the clouds and instead of in the cloud?Garzik: It was a point of economics: the more people that access a satellite, the lower the cost, which creates new business models that are not possible today due to higher costs, as well as making existing space business models much lower cost.With regards to use cases, there are a few categories:The software is associated with a specific type of satellite payload (usually a type of camera or other sensor), authenticating and encrypting the data directly at the physical source. Multiple tenants can securely share physical satellite resources. This can only be done at the physical device, which is located in space.Increasing the number of spacecraft throughout inner space, LEO/GEO, produces the need to avoid going space-to-ground-to-space for a number of different applications. In-space processing is faster due to the laws of physics.Elements of space settlement. Businesses that want to explore space jurisdictions have already existed, but never before had a meaningful way to truly operate off-planet in a way that matches the org’s decentralised / resilient goals.Those business models that were created by entrepreneurs, just as the Internet itself spawned many new businesses and business models not thought of when the pre-Web engineers were sending text-based email to each other.11. When can we see actual use cases for SpaceChain? Does it have any real use case since it is a utility token?Garzik: Space business occurs on frustratingly slow timescales! I wish the world would go faster.Ultimately, it takes a long time to build a space network.The space network will use tokens for (1) network registration, (2) network access, and (3) one of several payment methods for space-based activities such as remote sensing, remote imaging, transmission, data storage and more.We are working on that specific whitepaper right now. We call it “DSI”, the Decentralized Satellite Infrastructure. Keep an eye on https://github.com/dsi-org12. Will people be able to contribute to the whitepaper? I am very interested in contributing to the whitepaperGarzik: Yes, the whitepaper will be one of the repositories on the Github. It will be open to contributions for a couple months, then frozen.13. I’m curious how you are going to bring some kind of economic value to investors of SPC?Will it be for the usage of the network? Or are you planning to maybe move to some kind of DAO situation?Garzik: There are at least three targets for the SPC token: network access, network usage, and payment. The general thesis is that everyday SPC holders benefit from there being demand for the token, generated by people acquiring the token in order to use it for space services, both terrestrial services as well as in-space services being paid for with SPC.14. You keep claiming SpaceChain is open source and decentralized. So far there has never been any repository open to developers. Leave alone, not much peer review possible because there are no github updates. When Web 3.0 is evolving so fast how will you handle competition?What if SpaceChain takes too long and never takes off like how Dunvegan Systems never took off?Garzik: There are several repositories available at https://github.com/spacechain.More recently, thanks in part to SpaceChain, there are also repositories at https://github.com/coresemi and https://github.com/j-core.Lots of working code has been made available to the open source community. SpaceChain has also tested a lot of this code in space conditions, on the International Space Station and in the satellites SpaceChain has launched.Space is slow but progress is clear… and open.Check out the full AMA here.Keep up-to-date with all of SpaceChain’s developments via Twitter and subscribe to our newsletter on our website for our latest news.AMA with Jeff Garzik and Jeff Dionne was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

Space Law Decoded
All you need to know about how peace and order is kept in outer spaceImage Credit: PixabayThe topic of space law flows into several grey areas that stump even the most seasoned of professionals in the field. Are there set laws that govern the space realm? Who has intellectual property (IP) rights in outer space? Does any one country have more jurisdiction than the other? Is it the Wild West up there where anything and everything goes?The short answer to the above is that the arena is likened to a global commons, a realm of shared ownership such as the high seas, our overall atmosphere and the Antarctic. This basically means that every participating party or nation is responsible to cooperate in maintaining the landscape for the good of present and future civilisations.Image Credit: UnsplashFive treaties to maintain peace and orderThe United Nations Committee on the Peaceful Uses of Outer Space (UNCOPUOS) has five treaties in place that create parameters and boundaries to guide the industry forward.The first of these treaties, and perhaps the most well known of them among industry experts is the Outer Space Treaty of 1967. This basically presents principles for space exploration and operation, stating such terms as no nation can own space, the Moon or any other celestial body. Other terms of the treaty can be accessed here.The second treaty is the Rescue Agreement that outlines the obligations for any party that becomes aware that the personnel of a spacecraft are in danger. This means that if any participant in the space industry becomes aware that the personnel of a spacecraft are in distress, they must notify the launching authority and the Secretary General of the United Nations.The third treaty is the Liability Convention that establishes regulations for any damage in outer space. This was the treaty that was referred to when the Soviet Union was penalised after one of its nuclear-powered satellites crashed in Canada in 1978.UNCOPUOS has also established a fourth treaty named the Registration Convention that empowers the UN Secretary-General to maintain a register of all space objects.Last, but not least, is the Moon Agreement that requires all exploration and use of the Moon and other celestial bodies to be the province of all mankind, carried out for the benefit and in the interest of all countries. This basically means that the Moon should be used for the benefit of all states and all members within the international community.Image source: PixabayIntellectual property laws in outer spaceIt should be noted that several of the space treaties mentioned above were penned at a time when space exploration was still largely government driven. Since the landscape today has opened up considerably to private enterprise, many smaller businesses are concerned about their IP rights. It should be noted that the fundamentals of those treaties stay the same in this day and age.The Outer Space Treaty states that the national laws of the state in which a particular space object is registered in extends to the object. It also states that the country of registry retains jurisdiction and control over the space object and over any personnel thereof unless otherwise agreed among the launching States.This means that if a satellite is launched from Country A, or if a company from Country A purchases a launch, the satellite can be registered to Country A, and Country A’s (IP) laws will apply to the satellite.Image source: UnsplashLegal implementation an uphill taskAlthough seen largely as positive frameworks to regulate space travel, the space treaties in place have at times proven to be more effective in theory than when it comes to their implementation.Take the issue of space junk, for example, where damage caused by debris floating around in outer space is not covered explicitly by the five treaties. Establishing the causality of damage caused by space debris has also proven to be a challenge — it is often difficult to identify particulate debris and trace it back to the owner of the original launched object. This can become quite an issue of contention, seeing that there are [hyperlink to space junk blog] 34,000 debris objects in orbit that are larger than 10cm in size!Another example of where space law tends to remain ambiguous is when it comes to the militarisation of the industry. Although the Outer Space Treaty deems that space should be used exclusively for peaceful purposes, there is no prohibition on setting up military bases, conducting weapons testing, or bringing weapons into outer space. Opponents, however, feel that the construction of military bases in outer space could lead to war in the future and that legalities surrounding the issue should be made clear to maintain peace in outer space.Keep up-to-date with all of SpaceChain’s developments via Twitter and subscribe to our newsletter on our website for our latest news.Space Law Decoded was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

Moving towards a Decentrali...
In the first of our new series of interviews with space and blockchain industry thought leaders, we sat down with Chief Operating Officer Alessandra Albano to find out more about her role with SpaceChain and where the blockchain industry is heading in the foreseeable future.Could you tell us a bit about your professional background as well as your role with SpaceChain?Alessandra: I come from an operations background that has seen me specialise in designing and developing decentralised ecosystems for large blockchain projects. My areas of expertise also span from all matters of compliance to establishing strategic directions for clients across the blockchain space.At SpaceChain, my main role is to make sure that all processes are in place and run smoothly. It is my responsibility to plan all resource allocation and ensure that their distribution allows for maximum efficiency. I am also the go-to person when it comes to business strategy.On any given day, my role may see me involved in the evaluation of potential business opportunities and collaborations, product launches, commercialisation initiatives, public positioning of the company as well as the sourcing and acquisition of new talent. I also work closely with the R&D, partnership and tech teams to source funding and apply for grants as and when necessary.You recently conducted an inspiring workshop on how blockchain will be the next big disrupter in outer space. How will the integration of blockchain technology shape the evolution of the industry?Alessandra: It is evident that the space industry is becoming more and more of a conduit to allow legacy companies such as those in the defense and military spheres as well as publicly funded organisations to evolve into fully commercial enterprises.Many of these companies are currently going through tough times, feeling the economic impacts of a global pandemic. I strongly believe that innovation is the one factor that can create the bridge for these organisations to get back on track. This is where blockchain technology can play a large role, leveraging space infrastructure to enhance existing terrestrial blockchain networks (for example, by amplifying reach or increasing its resilience).Blockchain technology can also bolster and strengthen existing space infrastructure by enhancing the opportunities for secure data sharing amongst commercial partners. We will see a rapid shift towards blockchain solutions going far beyond cybersecurity and cryptocurrencies in the near future.In your opinion, what are the main challenges that the industry is facing, particularly when it comes to its overall governance?Alessandra: As with any industry that has experienced exponential growth during its (relative) infancy stage, I feel that one factor that the public needs to take into account is the fact that there will always be road bumps along the way. Many blockchain projects may seemingly be running out of steam, but if one were to take a closer look, there is still a lot of growth and innovation taking place behind the scenes. This may not be that obvious to the general public due to the incremental rate of this occurring.This is one of the main reasons behind a lot of stigma and lack of understanding across the industry. There is mind-blowing work being done by tech experts within the blockchain sphere, and the public needs to remain patient and trust that the sense of community and vision for the sector remains strong and unfazed through the development stage.The revolution of decentralised governance, which many are awaiting, will undoubtedly happen, but only after the technology itself becomes more resilient. After this, we will see more widespread and universal adoption by the wider business world.How will SpaceChain’s technology help to mitigate these challenges?Alessandra: Like everyone else in the blockchain community, we are working towards gaining visibility, trust and acceptance from legacy industry players. When it comes to SpaceChain, our main audience is the aerospace industry, which comes with its own set of challenges. We are essentially the only ones in this area (integrating blockchain in space) so the journey is a bit challenging but not one that we are not fully equipped to scale. This has been demonstrated in our success so far, working together with market leaders such as Nanoracks as well as collaborating in cutting edge research projects with companies like Deimos. A huge milestone for us was when we obtained funding and support from the European Space Agency (ESA).One of our main objectives is to prove that blockchain applications within the wider aerospace sector can bring benefits to existing players. We have already had three successful launches, released a groundbreaking industry-first OS that allows for multi-tenancy and earned our stripes as a space company with our custom-developed hardware.The next step will be centered on finding software applications for the industry using blockchain, and I can’t wait to find new ways to bolster and strengthen the entire community through our developments.What excites you most about the future of the blockchain industry?Alessandra: As I said earlier, the industry is still at its infancy stage. We are merely warming up and nowhere near experiencing its full potential.I would like to see examples of decentralised ecosystems running at capacity and economic implementations tested for mainstream adoption. I am extremely thrilled whenever I see tokenised applications starting to develop. An example that comes to mind is the Brave browser and its tokenised rewards system. Even closer to home (although geographical barriers mean little in the industry), we have the ride sharing Tada that rewards drivers and customers with utility tokens.The potential for such applications are limitless, and it will only be a question of time before widespread adoptions from existing businesses materialise. I am also looking forward to a fast track journey towards national digital currencies, which I hope will eventually succeed at mitigating the risks and impact of global recessions just like Satoshi intended when he conceived Bitcoin.What do you enjoy most about your role with SpaceChain?Alessandra: I would have to say that the one thing that makes me love coming to work is my team. They are a bunch of talented and considerate people and I feel extremely fortunate to work with them on a daily basis. Their keen sense of curiosity and reckless ambition are two factors that are so important in the industry we cover and if there is one team that can successfully integrate blockchain technology with the aerospace industry, this is the one.On another note, the work that we are doing is truly cutting-edge. We explore uncharted territories every day with our tech and this brings up a sense of contentment that is hard to describe. I hope that, as a team, we will be able to leave a mark and build something that will truly advance the New Space Economy.Finally, I have always been a bit of an AV Geek, from plane spotting to listening to ATC conversations as a hobby. Having the opportunity to make this my full-time job is a dream come true.You can connect with Alessandra and the rest of our team as well as keep up-to-date with all of SpaceChain’s developments via Twitter and subscribe to our newsletter on our website for our latest news.Moving towards a Decentralised Revolution in Outer Space was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

Space junk: Why it’s everyo...
Estimates by statistical models early last year show that there are over 34,000 debris objects in orbit that are larger than 10cm in size, 900,000 that are between 1cm and 10cm and 128 Million between 1mm and 1cm!Space junk, also called space debris and space garbage, refers to human-made objects in outer space — usually in the Earth orbit — that no longer serve any purpose. These objects typically come from satellites and spent rocket stages as well as the fragments from their disintegration, erosion and collisions. They also include non-functional spacecraft, abandoned launch vehicle stages, mission-related debris and fragmentation debris.With the space industry experiencing exponential growth over the course of the last few decades (coming from the increased number of launches), the amount of junk floating in outer space is enough to draw valid concern from analysts. This figure is touted to total around 8,000 tonnes, made up of thousands of defunct satellites as well as hundreds of thousands of smaller objects that are currently impossible to assess in definite terms due to their minute size.The main concern with an increasing amount of junk floating around in outer space are in the imminent collisions that may occur with existing satellites, causing catastrophic damage. The potential harm that may arise is exacerbated by the fact that these pieces of debris travel at breakneck speeds of over 17,000 mph, which is approximately 10 times the speed of a bullet. To confound matters further, one single crash could create even more debris, causing a much greater chance of more collisions in the future.Image Credit: NASAThe issue of responsibilityThere have been several incidents across the span of the last few decades that have raised eyebrows within the space community, posing questions on the legal responsibilities that nations have when it comes to the creation of space junk. One example of this was China’s 2007 anti-satellite test (ASAT), where it blew up one of its own weather satellites. Aside from causing considerable global military tension, the space industry was also concerned that the mission left behind more than 2,000 new debris elements of trackable size in low-earth orbit.Regulations surrounding the dumping of junk are far hazier in outer space than they are on Earth, with space debris mitigation not being explicitly addressed in the five United Nations (UN) treaties that deal with outer space and related activities across the sphere.That being said, a practical interpretation of the Outer Space Treaty shows that it is the duty of all nations involved in space exploration to do their part to mitigate debris, since it can hinder their right to freely explore and use outer space. The United Nations Committee on the Peaceful Uses of Outer Space also encourages all space participants to refer to its Debris Mitigation Guidelines that provides valuable strategies for the reduction of debris release during normal operations.Image Credit: PixabayJoint tracking efforts between government bodies and private enterpriseEfforts to track space junk have been made on both the government agency as well as private enterprise front.According to their website, NASA’s Orbital Debris Program Office (ODPO) conducts measurements of the orbital environment and implements mitigation measures to protect the users within it. The programme is aimed at creating an improved understanding of the orbital debris environment and measures that can be taken to control debris growth.On the commercial front, companies such as LeoLabs are monitoring up to 250,000 dangerous objects smaller than 10 centimeters (4 inches) wide that orbit Earth. This data will be key in assisting satellite operators and government agencies to avoid catastrophic collisions during their endeavours in outer space.Image Credit: PixabayTechnological advancements to reduce orbital debrisThe space industry has responded appropriately to growing concerns of increased debris floating in outer space, coming out with solutions that promise to solve the issue.The European Space Agency (ESA), commissioned the world’s first space debris removal program in late 2019. The initiative named ClearSpace-1 will help establish a new market for in-orbit servicing, as well as debris removal by launching the world’s first orbiting junk collector, a four-armed robot that tracks down space waste like Pac-Man in a maze, by 2025.A harpoon developed by Airbus Defence and Space in Stevenage, England, has also proven to clean-up orbital traffic lanes, collecting dead satellites and rockets and driving them back into Earth’s atmosphere to burn up.There has also been a myriad of proposed solutions made by private companies to solve space debris issues that could be rolled out over the span of the next several years. One such enterprise has a plan to work with governments and businesses to build a retrieval mechanism within a spacecraft before a launch. If the satellite fails prematurely, an Astroscale spacecraft would launch to intercept the defunct satellite and dispose of it.The issue of space junk is one that SpaceChain is constantly aware of. We strongly advocate for standard practices in dealing with deorbiting satellites and embrace any further advancement in technologies to deal with this problem.As always, you can keep up-to-date with all of SpaceChain’s exciting developments via Twitter.
