Identity HubAs promised, this version of Keepin is connected to a new service: the Identity Hub. We’ve talked about it in more detail in the educational series we created about Self-Sovereign Identity and Decentralized Identifiers. In short, Identity Hub is a decentralized, off-chain, personal datastore that puts control over personal data in the hands of the users. It allows users to store their sensitive data — identity information, official documents, app data, etc. — in a way that prevents anyone from using their data without their explicit permission and enables the user to share verified information with other members of the network.We are creating a service ready environment. Once the service providers are onboard, you will be able to access the services and share the information that you want while knowing exactly who has access to your information.2. Data VerificationTo share information, data has to be verified. With new Keepin v1.3, you are able to share your verified data as many times as needed. Keepin supports phone number (currently for Korean citizens only) and email verification at the moment.3. Data StorageKeepin v1.3 supports the storage of your Passport and Student ID information. Once you input your information, it will be stored on your device only, encrypted and connected to your META ID (your decentralized ID). Read more about decentralized ID (DID) in our educational series. We will be continuously adding more types of credential options to store.What’s NextDIDaaSMetadium is focusing on a more specialized business model focusing on identity access management for B2B/B2B2C: DIDaaS (Decentralized Identity as a Service). This will be included in the new version of Keepin to facilitate bringing new services and partners to the ecosystem.Service ProvidersWe are working on onboarding reliable and innovative service providers to open access to verified information sharing and exchange. The Keepin app and the Identity Hub provide an infrastructure for DID information exchange in a trustworthy, transparent and protected manner. These are the pillars of true self-sovereign identity system.Claim & AchievementAs we onboard new ecosystem players, the claim and achievement feature will roll out allowing you to make claims and get rewarded for your achievements. Please refer to the following video for details about the claim and achievement feature.https://medium.com/media/d837ebb3cbd316d51541b795353a0c18/hrefMetadium and all the solutions powered by Metadium comply with the latest data privacy policies, making our solutions safe for users and service providers.

A letter from Metadium CEO ...

Dear community,The year 2019 has been an irrefutably significant year for both the legacy and the early blockchain companies. Most of the early blockchain industry players realized the gap between the idealistic de-centralization business model and the reality of the existing industry ecosystem. However, many primary players from the legacy industry not only began to realize the real value of blockchain technology, but also publicly embarked on developing blockchain-based services. Some say that the decentralizing vision of the blockchain companies is over-valuated, others say it is totally under-valuated. I agree with this last thought.To realize the idea of decentralization, we need to change the rules of the game gradually and start building a new system that can support these changes. The benefits of these new rules and system should be acknowledged by the mass public.In the past two years, the industry tried to bring changes through a crowdfunding tool, called ICO, and I think it had half of success. While ICOs opened the door to a new way of funding, the initial supporters of the technology have turned their backs on the market due to excessive speculation. In addition, the uncertainty in government regulations, the prolonged bear market and the absence of business models are making the situation difficult for many projects. It’s a pity how the external uncertainties — like the lack of government regulation — are negatively affecting the evaluation of individual projects and limiting their potential. However, I also agree that the blockchain industry should reflect on its past practices and develop its own disciplines.Sensing such industry trends in the field and pursuing our company’s vision, our team has been quickly adopting and changing its form and direction. I’d like to share some of the high level business strategy changes, how they will impact our company’s business plan, and the progress we’ve been making around such changes.Before I end this letter, I want to express again my sincerest appreciation for all of your support and trust in our vision and the team. We’ve been working day and night to over-achieve our goals; and I have been always sympathetic of how you all have been persevering over the ups and downs throughout this challenging time. I wholeheartedly ask you to keep your poise and look at the industry and our company in the longer term. We won’t let you down.Sincerely yours,Justin ParkFollow us on Medium, Facebook, Twitter and join our Telegram Group to receive the latest updates.

Metadium Half-Year Progress...

Dear Metadians,We’re well into the second half of 2019. Our team took a look at the past eight months to evaluate what we have achieved and in which areas we must improve on to continue our effort to become a leader in bringing decentralized identity (DID) to the real world, and finally bringing the power to manage your identity back to yourself.Since the very beginning, Metadium has been on a mission to return the data ownership to its rightful owners. Your data is what makes your digital identity and, by extension, you. Our team fully recognizes the importance of one’s identity as it is at the heart of every service and product produced nowadays. The growing number of companies who are entering the blockchain identity management market is the proof that the problem Metadium aims to tackle is dire and its resolution will benefit millions and beyond. Despite the change is slow, our team is confident that we will and can deliver this to the mass public; and we are seeing many signs in the industry and market for such movement. We truly appreciate your support and interest in this great mission. We really hope that we can journey on together until we finally see our vision to unfold in our real life.Now let’s review the happenings of the first half of 2019.PRODUCT DEVELOPMENTThe core of all businesses lie on strong product backed by solid technology. Past eight months, our team’s foremost focus has been designing and developing product architecture and infrastructure of Metadium’s DID system. Actually, we over-achieved our milestones and very close to the completion of a fully functional and highly advanced DID system and solution. Here are some of the major milestones we achieved.Fundamentals of Metadium DID system for your reminderFebruary 2019 — Keepin v 1.0To give an access point to the mainnet after its launch and to streamline the token swap process for users, Metadium released Keepin v 1.0 on February 15 with the secure wallet feature available which can receive META and register other wallets holding META.March 2019 — Mainnet LaunchOn March 20, the Metadium Mainnet was launched three months ahead of the planned schedule. Despite the past year’s bear market, our team made sure to deliver on our promises. Some of the features of our mainnet include:Metadium client, gmet, is the command line interface for running a full Metadium node implemented in Go being forked from Ethereum, geth, source code.Metadium consensus mechanism: Stake-based Proof of Authority (PoA) with Raft leader selection algorithm up and running at authority nodes.Deployment on real network environment, running on 9 authority nodes deployed worldwide.A blockchain explorer (Mainnet and Testnet) to display addresses, transactions, and blocks. Metadium block explorer supports smart contract verification and read functions.Without installing Metadium client, gmet, users can reach out to Metadium blockchain via public Open API service (Mainnet and Testnet) around JSON RPC over both HTTPS and WebSockets.March 2019 — Keepin v 1.1Following upon the first release of Keepin that highlights a secure wallet function, after the stabilization of the mainnet, Metadium enabled the “Send” function to allow META coin holders to both send and receive META.May 2019 — Keepin v1.2In the latest version of Keepin we added the Meta ID feature, and by doing so it achieved its original purpose of being a gateway that protects your personal information and supports your sovereignty. The purpose of the Meta ID is to authenticate your identity while selectively sharing only necessary information. Right now, service providers can easily implement secure and reliable authentication system for their services with Meta ID whereas users can experience highly secure PKI-based authentication that outperforms ID/PW + 2 Factor Authentication with a simple biometric or PIN authentication.BUSINESS DEVELOPMENTApril, 2019 — Decentralized Identity Foundation (DIF)Metadium joined the DIF, an organization focused on developing the foundational elements necessary to establish an open ecosystem for decentralized identity and ensure interop between all participants. Companies like Microsoft, IBM, Sovrin, and Civic are members of DIF. It is not a surprise that we, as a company, put a big emphasis on security and safe management of personal data. To further research and develop the future standards that will apply to the protection of our identity, we joined the Decentralized Identity Foundation along with other major industry innovators.March, 2019 — Partnership with Unity TechnologiesTo lead decentralized identity management in game sector, we chose to partner with the most influential game developer community and real-time 3D (RT3D) development platform in the world, Unity Technologies. As a part of our partnership with Unity, we will be presenting Meta ID Software Development Kit (SDK) on Unity Asset Store in the near future. Millions of game developers will be able to implement Meta ID to provide decentralized virtual identity to their users.Business Development by CoinplugWe have decided to partner with Coinplug in order to lead mass adoption of Metadium’s DID system to public sector and enterprise level business ecosystem. Coinplug, being a leader in blockchain adoption in enterprise level companies and organizations, has successfully acquired and are currently working in the projects, which may establish the foundation for DID’s mass adoption. The most of its projects will include the use of DID architecture and infrastructure developed by Metadium team.College Certification Project with Korea Internet & Security Agency (KISA) and SK telecom consortiumDID-based internal mobile pay with Korea Post CenterDID-based scammer/phishing prevention service with Institute of Information & Communications Technology Planning & Evaluation (IITP)DID-based public security service and mydata market with Busan Blockchain De-regulatory ZoneCoinplug, as our regional business development partner, is continuing its effort to bring blockchain to real world applications, using solutions provided by Metadium team. Though we cannot disclose the details due to non-disclosure agreement with Coinplug, we can promise you that successes from Coinplug’s businesses using Metadium’s DID system will return to Metadium communities’ benefits.Business PartnershipsMetadium has been developing many different partnerships to establish a solid foundation to deploy DID system when the core product is ready. We will announce our partnership development strategy and our vision for our DID ecosystem with the current progress in the following post on the future plans. But for your reminder, please note the partnership is still only the beginning of what we are trying to achieve. The fruit of the partnership will require endless improvements on the product and efforts to work with the partners.OTHER ACTIVITIESFebruary, 2019 — META Token listed on Upbit and Bittrex InternationalOn February 20th, right before the mainnet launch, META got listed on major international exchanges — Upbit and Bittrex International which was another step towards expanding our presence in international communities.May, 2019 — Metadium Ambassador Program (MAP)Another initiative that we took in the first half of 2019 was Metadium Ambassador Program (MAP) that ran in multiple stages and had over 400 subscribers. Creators and Storytellers teams were active and challenged with various quests. The goal for this program was to create a vibrant and active community of professionals, creatives and enthusiasts who push the boundaries and constantly innovate.Metadium team attended lots of events like…TMI meetup, Ethcon 2019, Fintech Belgium, Consensus 2019, KuCoin Blockchain Day, and Pocket Gamer Connects among others.Again, we’d like to express our sincerest gratitude for your support and trust in our business. Innovation takes time, but we are strong and experienced team to finish this race with success.In our next post, we will share our plans for upcoming months and details of the projects we’re working on.Please stay tuned.Sincerely,Team MetadiumFollow us on Medium, Facebook, Twitter and join our Telegram Group to receive the latest updates.

Youtube AMA Recap with CEO ...

Here is a short summary of the biggest announcements, insights, and updates on Metadium.The video recap is available below.Dear Metadians,Last Thursday, our CEO Justin Park and CTO Jeffrey Song sat down to update the community about the current development of the project and shared plans for upcoming months. Here is a detailed break down of the YouTube Live AMA that we hosted on August 29, 2019.Q: Could you please give a brief summary of Q1 and Q2 of 2019?Justin: It’s been a busy year for us. In Q1 we launched our mainnet, went through the token swap process, released the first version of the Keepin App. During Q2 we spend a lot of time in R&D and business development to create more use cases. Next version of the Keepin with Meta ID was released. Listings are taking more time than we expected but it is on the way as well.Q: Could you please update us on the status of Korea Post project, and other government projects?Justin: Before the update, I would like to clarify that Metadium is a technical partner of Coinplug. The government projects are directly engaged with Coinplug, and Metadium, as a technical partner, is a DID solution and public chain provider. To give a short summary, Korea Post project is leveraging blockchain for local payment, and Seoul Metro is using the blockchain for house sharing.Q: There was also a partnership with Unity Asset Store earlier this year. Is the development of SDK going according to the schedule?Jeffrey: I can expect that a lot of people are waiting for the SDK to be released on Unity Asset Store. All the development has been done, and now it is in the evaluation process. Unity has a rigorous review process that takes some time. I believe it will be available in a week or two.Justin: I would like to add that our partnership with Unity is a strategic move to create an actual use case. Unity Asset Store has around 6 million developers, who might help us to increase the use cases of blockchain solutions. This is an opportunity to educate developers before the end users and we are very excited about this partnership.Q: How about the next version of Keepin? When can we expect it?Jeffrey: As you might know, this is going to be a fourth release of the Keepin. Right now we are in the last stage of the integration test, after that we will go through quality assurance tests and around mid September Keepin should be available on the App Store and Google Play.Q: Can you share with us some of the features that we can expect in the new version of Keepin?Jeffrey: Yes, as was announced we are fully compatible with w3c DID spec. We have registered our DID method to w3c DID Method Registry and have become the member of Decentralized Identity Foundation. There are two major features that will be added to next Keepin version. One is for the end point agent that is Keepin side and the other is a cloud agent that is Identity Hub. Basically all data management functions have been included into Keepin v1.3. Keepin also can encrypt the data and store it into the repository that is called Identity Hub for backup or to share the data with other service providers.Q: What is Identity Hub?Jeffrey: Identity Hub is a data repository. User can write data in the data repository, user encrypts it before storing in the Identity Hub and also can give a specific user access to the data. Even the Identity Hub operator can’t look at the data. Your data is fully protected. The reason to use Identity Hub is to connect the service provider and the user, giving a secure means of access that is GDPR compliant and prone to any interruptions.Justin: One use case of Identity Hub could be a decentralized social network. Let’s say there is a social network service like Facebook but decentralized. And there are all sorts of posts and data that belong to the user. Identity Hub is a database where users can store that data. And users can give permission to specific users and services to access that data.Q: How do you plan to deploy DID through the industry? Any companies confirmed to use it?Justin: I would say that this is the most difficult part, the go-to-market strategy, not only for DID but also the blockchain. As a result, we’ve been repositioning from B2C to B2B company and working on how to package the services to the organizations or service providers. Because the DID itself was not perceived as a service yet, we’re having a hard time educating and explaining it to different service providers. There will be some announcements later this quarter or early next quarter about the enterprise solutions.Q: Any events that you are planning to participate in? Any community focused events that you are planning for us?Justin: We all know that the blockchain projects all start with the community. Our marketing team is considering better ways to engage with the community. In the past, we’ve been heavily involved in events and organizing meetups, but it proved to be less effective. So we’re rethinking our strategy to build a healthy and supportive communication with the community. This type of AMA is one way to improve our communication. We’re planning to engage in more events and exhibitions as speakers. Jeffrey is going to be a moderator at the Digital Asset Exchange Expo in Busan next week, I’m going to be a speaker during Blockchain Week in September. We are taking various opportunities to showcase Metadium.Q: What is your plan for listings on exchanges?Justin: Surely, a lot of community members are curious about the listings. It is understandable and there are a couple of things I want to mention. First of all, we are considering only global tier-1 exchanges for listing, even if it takes some time. Hopefully that will happen during this year. And the second goal is to list KRW pair which is important for providing more room for liquidity of META coin.Q: What the Metadium team will be working on the next couple of months?Justin: As I mentioned earlier, we have slightly adjusted our positioning towards enterprise solutions. In Q3 and Q4, we are pushing hard on packaging our solutions for enterprises. It involved a lot of effort on R&D and business development sides.Q: Any plans with on-boarding new Block Producers?Justin: At the moment we are receiving a lot of inquiries to become a block producer for us, but we are intentionally not choosing anyone yet. We want to choose Block Producers who can actually contribute to our network and be a representative of Metadium as a Block Producer. This year we are not planning on on-boarding new block producers, some time next year possibly.Jeffrey: We’ve released our token economic paper. You can review how we are going to distribute the block rewards to BPs. It is based on government system and it is evenly distributed. If you go to our block explorer, you can see that the mining node is getting the reward periodically.Q: Are there any projects of Coinplug actually using Metadium Mainnet?Jeffrey: Metadium Mainnet is a public blockchain. It has the same technology that is used in the private sector. So for Coinplug side, we are preparing some wallet services that will be ready to operate on top of the Metadium blockchain using Keepin. We intend to make full use of public blockchain and Coinplug is supporting. And as you might know, there are six government projects with Coinplug and all of them are using Metadium blockchain, with different configurations — public and private.Q: Why is the name of the project Metadium?Justin: Community members ask that a lot as well as how to pronounce Metadium. “Meta” means data of the data, “dium” comes from stadium. We get “data of the data stadium”.Q: What can I do with META coins at the moment?Jeffrey: META is a fuel, gas of our network. We are also providing a tokenization platform. As Justin mentioned, we are pivoting to enterprise solutions and positioning it as an identity as a service — IDaaS.Q: Could you provide more details regarding the latest news about Busan Regulation-Free Blockchain Special Zone?Justin: Yes, I’m very happy to announce that Coinplug was chosen to be a part of Busan Regulation-Free Blockchain Special Zone and work on public safety. And together with Coinplug, Metadium has a chance to work with Korean government in this special zone. It is a great opportunity to deploy Metadium DID in the district.Video Recap of the AMAhttps://medium.com/media/d733808f0ad28e3fdbb2759f98a42896/hrefLove,Team MetadiumFollow us on Medium, Facebook, Twitter and join our Telegram Group to receive the latest updates.
