pwolf88 — Community Spotlight
pwolf88 — Community SpotlightPwolf88 has been an active member of the community since 2017. A regular contributor to the OmiseGO subreddit, Pwolf88 and the team at OMGPool have created valuable resources for the OMG community like the OmiseGO News Feed, his explanation of Plasma, and the staking rewards calculator. This month, we get to know Pwolf88 and how the OMGPool team work together for the good of the community.Question: First of all, are you a developer?pwolf88: I used to be. As a child, I was already living with a father and two brothers that were all obsessed with computers and technology. In college, I studied programming but after a couple years of experience, I soon realized I was more interested in the business and analytical part of things. I learned to program in Solidity though, but that was more to get a feeling of the technologies. I leave the actual coding to the experts.Question: What got you interested in blockchain, how did it start?pwolf88: A friend of mine told me about Ethereum in the summer of 2017, but mostly from an investment point of view. At that time, the whole concept of cryptocurrencies was just a big casino to me. I quickly decided to learn the fundamentals behind it, before losing even 1 dollar on it. Soon™ I discovered the enormous potential of smart contracts and Proof-of-Stake consensus networks, which led me to research OmiseGO. After getting involved in the OMG community, I was offered to join the OMGPool team, as it is developing in a very organic way with members of the community.Q: How does your team work together?pwolf88: We all have different backgrounds and skills, and are all working in the same direction so each task is dispatched quite easily. We are also a small team, so we can adapt quickly to our needs. It’s amazing how people can cooperate almost effortlessly, when they all believe in the same thing and have the same goal in their mind.Q: What projects have your team completed and are proud of?pwolf88: The Staking Rewards Calculator on our website is often referenced in the community for rewards speculation and it will be even more useful when staking is live to estimate revenue for stakers, just like mining calculators do for miners. But the thing we’re most proud of is how we’ve integrated with the community and can respond to the needs that various members may have. For instance, we implemented the OMG News Feed because we believed that there was just too much ‘fud’ on Reddit and other social networks that could kill the interest of new people wanting to learn about the fundamentals of OMG in a healthy manner.Q: What OmiseGO technology are you excited to develop on?pwolf88: We’re most excited about the entire reason OMGPool exists: Proof-of-Stake. It’s a superior incentive model to Proof-of-Work, both in its economic model and its technical sophistication. We hold the belief that over time, Proof-of-Stake systems will become the dominant crypto platforms because of their practicality and accessibility, especially through the use of smart-contract-enabled staking pools where you still hold true ownership over your assets, as opposed to entrusting them to a custodian.Q: What use cases are you looking forward to see using the white label eWallet?pwolf88: One day I would like to experience the opportunity to collect loyalty points from local and online businesses I use as a customer, or to cash out my crypto assets to fiat money in a local shop.Q: What inspires you when writing for the community? What brings about interest in doing so?pwolf88: I love to write about topics that are so new and groundbreaking. If I think about the potential of blockchain in this digital revolution we’re living in, it feels like we’re way overdue and we need this more than anything to really get started with things like smart cities, machine coordination, and virtual reality. To me, the digitalization of payments is crucial, but it’s only a first step towards this bigger world we’re about to see.See what pwolf88 and OMGPool are working on by visiting their WEBSITE and MEDIUM PAGE.

Get with the Program
The OmiseGO Developer Program (ODP)The OmiseGO Developer Program (ODP) is an initiative that is part of the product development process. The objective of the ODP is to systematically and carefully facilitate usage and thorough testing of Proof-of-Concepts (PoCs) and early stage products in order to gain feedback for improvement. The program is aimed towards those who would like to build their own products, such as games, financial service applications, and education platforms on top of the OMG Network. Applicants of the ODP will fall into the developer category and are willing to work with unpolished and early stage codebase. Early testers and integrators are given early access to the new products OmiseGO rolls out. Those in the program will also have opportunities to interact with each other and with the engineering team. ODP application timelineThe ODP is an ongoing program and applications are accepted on a rolling basis. The goal is for ODP participants to participate as Alpha testers for roll-outs before they are released to the public in Beta. What this means is that there is no real definite timeline or start and end dates. While we have no definite dates set, here’s what we have planned out within the next three months: End of February to beginning of April 2019:1. Whitelisted access to the Alpha release of the OMG Network with integration guide2. Access to a JS Starter Kit to start making transactions quickly on browsers3. Communication channel established with OmiseGO Engineers4. Early access to a ‘Getting Started Guide’ to the OMG Network Aside from this expect other supporting services and libraries in other languages to be rolled out as well. Beyond the alpha and beta Releases of our network, participants can expect interactive discourse with the product and engineering team at OmiseGO, including opportunities to share your opinions on what product and features you would like to see and build that will make your life as an integrator easier. Given that acceptance to the ODP will happen on a rolling basis, the acceptance criteria is subject to change with each phase of development. Applicants who have applied and have not gotten accepted can still expect to be contacted in the future.Sign up for the OmiseGO Developer Program today.Get with the Program was originally published in OmiseGO Network on Medium, where people are continuing the conversation by highlighting and responding to this story.

OmiseGO February Roundup
Alpha release (Ari)In February, we debuted our Alpha release (Ari) at ETH Denver. Ari is the conclusion of the current stage in our development cycle. It is the point in which we’ve become ready to start using our Plasma MoreVP implementation on a public Ethereum network with users.Ari, being on a public Ethereum network now allows us in tandem with partners, to test the integration of third-party apps with our Plasma MoreVP network. At ETHDenver Hoard ran an iteration of Plasma Dog with a limited-edition Bufficorn skin for the Hackathon.The Alpha release enables us to rigorously test and search for bugs on the network together with our partners like Hoard. Being on a public network allows more developers and entities to use and test our product allowing for a well-rounded feedback mechanism for creating iterations faster. In the first 24 hours of Hoard running their application on our network, we were able to test the capabilities and capacity of our system. Over 28.5k transactions were processed during that time.Read more about Alpha Release (Ari) on our blog.OmiseGO Developer ProgramTogether with the debut of Ari, we launched the OmiseGO Developer Program (ODP). The ODP is an initiative that is part of the product development process. The objective of this program is to facilitate the usage and thorough testing of our releases and other products.The ODP is an ongoing program and applications are accepted on a rolling basis. The program is aimed towards those who wish to build their own applications and programs on top of the OMG network. Early testers and integrators are given early access to test new products OmiseGO rolls out. As part of the program, testers and integrators can interact with one another and with the OmiseGO engineering team. There will also be opportunities to provide feedback, comments, and suggestions on what products and features should be built to make developer integration easier in future iterations.Sign up for the OmiseGO Developer Program todayTechnical UpdatesPlasmaEarly in the month, our engineers focused on the development of the in-flight exits for ERC-20s and transaction metadata support, and updated Elixir and our Exthereum dependency. The team monitored the performance of our testnet on Rinkeby. Satisfied with the overall network performance, the initial updates to omg-js were merged. In the process, several bugs involving geth were identified and fixed.The biggest news for February is the implementation of the Plasma MoreVP on a public Ethereum network –alpha release (Ari).For more details check out Plasma Updates #13 and #14OmiseGO eWallet SuiteWe start off the month of February with the release of eWallet version 1.1.0 of the iOS SDK. This version allows the iOS apps to utilize the eWallet’s v1.1 features, such as user signup and login, and password management directly from their apps. This update also enables providers to setup their eWallet system without an intermediary application that stores and manages users.During the second half of the month we focused on hashing out the technical design and strategy for Ethereum integration. This was a challenging task as it required consensus on how the eWallet would interact with the Ethereum network; everything from how public and private keys would be generated, stored, and retrieved for transaction signing, the strategy to operate on potentially thousands or more wallets, syncing token information and transactions and handling unexpected connectivity issues.Additionally, we also worked on the Elixir 1.8 and Ecto 3.0 upgrades. These items, though invisible to users, ensure that the backbone of the eWallet codebase will continue to receive the latest features, security and bug fixes.We started on our initial blockchain integration which determines how the eWallet generates new blockchain wallets. This lays the foundation of how the eWallet would interact with a blockchain client to retrieve wallet balances, tokens, perform transactions, and much more.And finally, we have worked on finalizing the scope and tasks for eWallet version 1.2 and v2.0 cycle. This marks the beginning of the Ethereum integration work which a lot of us have been anticipating.For more details on what the team worked on in February, check out eWallet Updates #17 and #18Mobile Money and Financial Inclusion Feb 26–27 2019OmiseGO’s Business Development Team presented the next generation financial services for mobile money to better serve end-users in Myanmar.

Tousthilagavathy — Develop ...
Tousthilagavathy — Developer SpotlightTousthilagavathy has been a member of the OMG community since October 2017. As an active member on the OmiseGO’s reddit, he has developed content made available to the OMG community including a comprehensive ELI5 OmiseGO whitepaper. This month, we got to know a bit more about Tousthilagavathy, his background, and how he got interested in the network.Question: What got you interested in developing, how did it start?Tousthilagavathy: I got hooked the first time I was introduced to computers at a young age. Programming fascinated me. I’ve always found abstraction, logic and deduction to be interesting. So, I guess that helped with the interest. I started developing with the Basica and C programming languages to do simple graphics.Q: What is your development process?Tousthilagavathy: Most of the development I do involves quite a bit of abstraction and research, so I follow the iterative development process it’s a lot of repetition till I’m happy with my design. I also use Scrum, for managing my product development.Q: What projects have you completed and are proud of?Tousthilagavathy: While I’ve completed a lot of projects, I have to say I’m most proud of having designed and programmed engines to do automation, simulations of crowds and worlds. And also I’ve done system programming related stuff like memory managers, process managers and custom scripting languages.Q: What projects are you currently working on?Tousthilagavathy: Currently I’m working on a networking-based web app that has elements of social, business, payments and incentives.Q: What OmiseGO technology are you excited to develop on?Tousthilagavathy: I like the currency agnostic, crypto, DEX and scalable aspects of the OmiseGO tech.Q: What opportunities do you want to explore on the white label eWallet?Tousthilagavathy: I want to look at payments of course and play around with the various forms of incentivization. These functions are in line with the current work I’m doing, so it could be cool to explore the eWallet.Q: What inspires you when writing for the community? What brings about interest in doing so?Tousthilagavathy: I just like sharing my knowledge with the community. Sometimes the inspiration is purely accidental, for example, some time back when Givedirectly was tweeted about by OmiseGO, I got to thinking about it one evening and for the fun of it, I had written out the distribution logic on my blog.See more of Tousthilagavathy’s work HEREOriginally Published in our January 2019 NewsletterTousthilagavathy — Developer Spotlight was originally published in OmiseGO Network on Medium, where people are continuing the conversation by highlighting and responding to this story.

OmiseGO eWallet Suite Demo
https://medium.com/media/e93f8d88fc1798e90d7a16e2c738d9ba/hrefThe OmiseGO eWallet Suite is a white label, open-source, and fully customizable eWallet to digitalize and store all types of assets. What does this mean?First of all, being white-label, the eWallet is yours to brand as your own. Second, as it is open-sourced and fully customizable, you can change and develop it to suit any need you may have. You may use it to store company loyalty points, employee benefit points, game tokens, cryptocurrency, or even fiat.creating a token on the eWallet SuiteWhile the eWallet Suite can certainly stand alone on its own without having to be linked to the decentralized exchange (DEX), it was created with future integration into the OMG network in mind. This is where it can truly shine. With OMG network integration, a company can offer multiple transactions at high speeds. The decentralized exchange enables interoperable trade of different types of assets be it points, fiat, crypto, or any other asset that has been digitalized and stored on the OMG network.In the video Thibault, Integration Lead Engineer at OmiseGO, walks us through the various features of the eWallet Suite, and show us how the eWallet and its features may be used in the real world.Learn more about the eWallet Suite here.Read up on the latest eWallet development updates here.Originally Published in our January 2019 NewsletterOmiseGO eWallet Suite Demo was originally published in OmiseGO Network on Medium, where people are continuing the conversation by highlighting and responding to this story.

OmiseGO’s Alpha Release (Ari)
We’re happy to announce our alpha release aka Ari! Here is an update on how we arrived at Ari and what it is.What happened after Devcon 4?Back in October 2018 while we were running our implementation of Minimal Viable Plasma (MVP) at Devcon 4, we gained valuable insights into the operation and performance of our services. We even had our first production incident during the conference, which we mitigated to keep the services live. One of the key elements of software delivery is getting performance and operational information from the deployed code and using that to make data driven decisions that ensure that the services we are building are resilient for users. This continued iterative process is essential for ensuring the safety and trust in our network, which is paramount to us. After all, this is a network that is transacting real world assets which have value.What was the incident at Devcon 4?When we deployed the blockchain services that power Plasma Dog, we also deployed Quest — a service to view transactions on the network in real time. The Watcher stores network transactions in a relational database. Quest connects to the Watcher to get the transactions that have been verified. We had configured the client-side library of Quest to poll the Watcher every 15 seconds to get an updated list of the transactions on the network. This means that if a user left a browser tab open, they would continue to make API calls to get two hundred of the latest transactions per request. When we had several thousand users on Quest continually requesting updates the transaction data, we quickly exhausted the resources available to us on the database. The CPU on the database pegged at 100% and refused further connections, the Watcher could not connect to the database and failed, causing the Quest service to fail too. Fortunately as we have a separate Childchain and Watcher architecture, the blockchain continued to be operational.CPU usage of the database that the Watcher uses.This graph is the CPU usage of the database that the Watcher uses. Shortly after it hits 100% utilization, you can see at 2:45 where the database refuses connections in an attempt to shed load, which it does successfully (causing the failure of the Watcher). At 2:52 we restarted the Watcher, only for it to fail again 5 minutes later due to the volume of requests. During the period between 3:00 and 3:20, we determined that the lack of CPU resources was causing this failure condition and re-provisioned the database to handle the load we were experiencing. At 3:24 services were operational again.We continued to monitor how the services were performing and at 4:25 we could see an increase in the CPU load again. From the Watcher’s monitoring data we could see that several requests per second were coming from an API call associated with Quest’s transaction polling API. We deployed a hot fix on Quest to change that behavior, with the trade-off being that users would have to refresh the page manually if they wanted to view the updated transaction data. After we deployed that, at 4:43, the database CPU load started to reduce.Database CPU load reducing.In the following weeks after Devcon 4, we redesigned our service deployments and began the process to implement Plasma MoreVP. Some of the highlights from this time are:We launched our Childchain and Watcher services on the public Ethereum test network Rinkeby.We discovered techniques that meant we could reduce our gas usage on the root chain (including not writing empty blocks to the rootchain and a modifying the gas price selection mechanism).The service deployment was redesigned to be more tolerant to failure conditions that we identified during and after Devcon 4.Continuous integration and deployment of the blockchain services was implemented to provide faster signal to developers of an error condition.The public APIs were redesigned to be consistent across all of the services in the OmiseGO ecosystem, which helps for eWallet integration.We found a whole range of bugs, including a serious one where blocks weren’t being written to the root chain.The Plasma smart contracts, Childchain, and Watcher were engineered to implement Plasma MoreVP.TerminologyWe’ve switched from calling these releases the internal and external testnet to alpha and beta, respectively. We’ve been using this terminology internally for some time and we’ll be using it publicly from now on as well. We’re building software and we’d like to follow the software release life cycle naming convention. It offers more clarity on where we are in terms of our software development stage. Alpha denotes software that is complete enough for internal testing, which is typically carried out by people other than the software engineers who wrote it. Testers can include individuals within the same organization or community that developed the software. Beta test is the second phase of software testing where we’ll be opening access to everyone.What is the alpha release (Ari)?The alpha release, which we’ve nicknamed Ari (see name explanation below), concludes the current stage in our development cycle. We feel we’re in a good place with our builds, deployments, and smart contract development where we’re ready to start using our Plasma MoreVP implementation on a public Ethereum network with users. This allows us in tandem with partners, to test the integration of third-party apps with our Plasma MoreVP network. Hoard will be using our test network Ari at ETHDenver!To celebrate ETHDenver and the launch of Plasma MoreVP, Hoard has developed a limited edition Bufficorn Skin for the hackathon. Thank you to Hoard for pioneering this program, thus far, and a shout out to the Burner Wallet team! Check Hoard’s blog post for more details on the More Viable PlasmaDog on Rinkeby and how players at ETHDenver can authenticate their Plasma Dog session with their NFT Burner Wallet to unlock the playable Bufficorn skin.Getting to this point has taken a lot of hard work and dedication to overcome the issues we’ve discovered while building. Here are some of the challenges that we’ve found and addressed along the way in 2019 alone:In certain conditions exits from the Plasma chain were unchallengeable. This meant that anybody could deposit to the Plasma MoreVP contract, perform an exit, and the entire chain would become invalid. This results in a denial of service (DoS) condition which would have taken down the whole network for everyone.A race condition on the Watcher start-up was discovered where unchallenged exits were processed before other modules of the system started. This meant that for users running their own Watcher, it would appear the chain is faulty (has a byzantine condition) — which would prevent normal operation, including transactions.We found a bug where an attacker could drain all the ETH from the deployed Plasma MoreVP contracts.Protection against re-orgs on Ethereum has been added to the Plasma MoreVP contracts.We implemented a flexible deployment mechanism for deploying services in production or locally on a developer laptop.Support was added for other components of the exit game including in flight exits and piggybacking.We’re really excited to be at this stage of the development and look forward to more load on our Plasma MoreVP services as part of the OmiseGO Developer Program (ODP). The ODP is an ongoing program of early testers and integrators who will be given first access to our products, documentation and tooling.View our transaction explorer and keep track of the OMG Network Status (Ari)!Why Ari? 🚋 🚋 🚋The naming convention for test Ethereum networks is to use train stations. Rinkeby and Ropsten are stations in Sweden, Kovan is a station in Singapore. When we turned up the environment that was used for Devcon 4, we were huddled in a hotel room as we deployed the services and ERC20 tokens that would be needed by Hoard to operate Plasma Dog. During this, we realized we didn’t have a name for the network. We checked on a map and just around the corner from the conference center was Vyšehrad station. So that’s how we named that one.We wanted to continue the naming convention with our alpha release and decided it was time to put Bangkok on the map. Ari is: 1) Easy to say for non-native Thai speakers, and 2) Can also mean “hospitable”, “accommodating” or “gentle”. Please be gentle with our test net. 😄What’s next?We’re going to continue the same iterative process that we’ve been building with to date. All software has bugs and we will not rush releases or perform any activity that has the potential to compromise user safety. The next version (beta) of our network will be a publicly available release that anybody can use! We’ll use the beta phase to observe real-world usage and look for bugs or flaws that haven’t been discovered in the alpha phase. We’ll deploy the network to mainnet when, and only when, the code has been thoroughly tested and audited and we are confident that it’s a safe place to put real money.We’re currently planning a video workshop pre-event and a face-to-face workshop ̶h̶a̶c̶k̶a̶t̶h̶o̶n̶ during EDCON HACK, which takes place this April in Sydney, Australia. We will have a bug bounty in place to catch more bugs and security vulnerabilities as a part of the process of getting ready for mainnet. We will develop more tooling around the interaction with services and the status of the systems we’ve deployed — eWallet Plasma integration. Stay tuned for more details.Want to get involved?If you would like to get even more involved with the next stages of development and building, we’re hiring!Stay updated.

OmiseGO January Roundup
Technical Updates:PlasmaThe new year started off strong with a new iteration of the internal testnet. The improvements were based on the data and feedback received from the initial iteration. Our goal is to create a production environment that is resilient and can handle real-world continuous usage. While not the easiest task to do, we’ve made our first step in that direction with this version.To ensure that we are prepared to open up to the real world -with multiple users, interactions, and connections, we’ve set up means to better study and view the chain, and develop iterations of it faster. The internal testnet is now fully monitored and instrumented with telemetry, logging, and exception reporting -allowing for faster feedback mechanisms and fixes. While we believe to have created a stronger environment now, we continue to actively test the new environment to build towards further resiliency.The second half of January was focused on our More Viable Plasma (MoreVP) implementation. With our focus on MoreVP we are looking to ensure user funds (in ERC20) are safe. In line with that, we’ve been integrating the in-flight exit support from the root contracts into the child chain and watcher.The MoreVP has all the production support services that we set up with our new internal testnet. Again, what this means is that we can continue to test and validate data and create solutions and new iterations faster. Along with our heavy security testing, we’ve also created an API format, which is consistent across the child chain, watcher, and eWallet so that it’s cleaner and more developer-friendly.To get more details on our work in January check out our Plasma Update #11 and #12eWalletFor January we focused on the release process of eWallet 1.1. This entailed continuous testing, several bug fixes, and the thinking up and applying of last-minute features to add. We will continue to do this process till we’re satisfied with everything for release.Of the accomplishments we’ve had in January there are three that stood out the most for the eWallet team:First, it would have to be the finalization of the ‘Activity Log System’. This is an important feature that allows the users of the eWallet to know the exact details of all activities done. Users will be able to see who did what and when they did it. A good feature for accountability and an added measure of security.Second, we’ve developed a better build process, which includes running the E2E tests. This is a great addition for developers as this provides a better and faster feedback loop. Working with this type of feedback loop will allow us to spot problems and fix them, ensuring less bugs are deployed into the staging system.And last but certainly not the least, we have the CSV exports for transactions. While we may have not added any major features this month, the CSV export would have to be the closest one to it. This feature, which was initially required by one of our eWallet-using enterprise customers, provides the ability to export transactions for accounting purposes. Users can export any or all transactions that have been made.To get all the details on our work in January check out our eWallet Update #15 and #16ShinhanCard Proof-of-concept demohttps://medium.com/media/8a5594bc613fd352e009127888c4e0d1/hrefThis was an exciting month for us as our exploration into possible technology applications with ShinhanCard has borne fruit. After months of collaboration with OmiseGO, the Korean Finance conglomerate demonstrates a cross-border PoC with the aim to expand the acceptance of ShinhanCard’s loyalty program to international markets and enable borderless interoperability.This demonstration shows the first ShinhanCard transaction using OmiseGO.

ShinhanCard Demonstrates P ...
Shinhan use case demoIn April of 2018 ShinhanCard signed an MoU with OmiseGO to explore opportunities in fintech and blockchain initiatives. Since then, OmiseGO has been collaborating closely with the company to exchange learnings and increase capacity to adopt blockchain technologies.In January of 2019, that MoU has resulted in a use case that demonstrates a cross-border Proof-of-Concept (PoC) aimed at expanding the ShinhanCard loyalty program internationally and enable borderless interoperability.https://medium.com/media/8a5594bc613fd352e009127888c4e0d1/href***This video has sound***The demonstration on video is based on a transaction of digital assets of tokenized value that are minted to represent ShinhanCard’s reward point. Shinhan Financial Group is one of the largest banking groups in South Korea in both assets and profit. The ShinhanCard reward point can be used in almost any online and offline merchant in South Korea, and if the card holders of ShinhanCard purchase products in the company’s payment app, called ShinhanPay FAN (Finance and Network), users can receive extra benefits from partner companies of ShinhanCard.In this scenario, FAN points are minted on the blockchain through a smart contract on the Ethereum network, deposited into a Plasma blockchain, and transacted on the Plasma blockchain from the merchant (ShinhanCard) to a user.For this demonstration to test and showcase their PoC, Shinhancard engineers use OmiseGO’s web interface for enterprise developers, which allow basic interactions with the OMG network. The interface mimics the functions of an eWallet suite and allows a developer to grasp the concept of plasma, and make direct, fast transactions.For the purposes of the demonstration, the interface does not include the watcher or exit functions of a plasma blockchain. The eWallet iteration with the watcher and exit functions are relatively new additions which you can learn more about HERE.Should ShinhanCard choose to adopt the OMG Network with merchant acceptance, users would have the ability to interchange local loyalty points with other merchants and customers on the network across borders and eventually exchange between any digital asset, as per the design of the OMG Network.This PoC was helpful in allowing the ShinihanCard team to really understand what they could potentially do with plasma and blockchain itself. With that OmiseGO and ShinhanCard look forward to furthering research, learnings, and development together.ShinhanCard Demonstrates Proof-of-Concept was originally published in OmiseGO Network on Medium, where people are continuing the conversation by highlighting and responding to this story.

Common misconception and p ...
Common misconception and perhaps up for debate — but we consider it an on-chain solution because it ultimately relies on the security properties of the Ethereum blockchain. Side chains may report balances to the main chain but rely on the security of their own consensus mechanism; plasma chains have a separate consensus mechanism as well but allow users to withdraw to the main chain at any time with their balances from the last valid block, so that even if the plasma chain breaks users’ funds are secured by the root chain.

It’s that wonderful time of the year again. Winter is finally here (summer in other places). If you’re reading this, thank you for staying with us.There are a few days left before we cross over to 2019, so before we look forward, let’s take a moment to look back at 2018. The road was long and winding for us at OmiseGO, with a number of achievements and a handful of challenges; some we were prepared for, others, we learned the hard way.As always, our fate is tied in many ways with that of Ethereum and the wider blockchain industry, and it has been an eventful year across the board. Ethereum 2.0 is under heavy development, bringing sharding and other improvements to the Ethereum blockchain. Plasma research has emerged as a community-wide effort toward better on-chain scaling for a wide variety of use cases. This type of collaboration between projects is one of the most remarkable and rewarding aspects of working in an open-source community, and the Ethereum space in particular, and we’re proud to have been leaders in the effort.As things move fast and not necessarily within a straight path in our industry, we’d like recap our activities from January 2018 right up to present day. We aren’t able to pack every single detail of a year in one post, but here are some key highlights.January 2018The first Plasma minimum viable product technical specification is announced and the Proof-of-Concept (PoC) is created and iterated upon.February 2018eWallet Suite repo is made public! Read here.March 2018OmiseGO announces a donation of $1m USD equivalent in OMG to GiveDirectly, an organization that provides aid to populations living in extreme poverty in the form of direct cash transfers to individuals — and with it our intention to explore the possibilities of using crypto to support these and other efforts to help the poor.Plasma Cash, a Plasma construction is proposed as a scalability option that turns fungible assets into unique “coins” on the root chain. This increases security and usability but adds a new challenge as well: it requires each coin’s entire history to be tracked, which involves storing and transmitting a tremendous amount of data. Reducing history size to make increase the viability of Plasma Cash is a subject of ongoing research.April 2018 The eWallet Suite (SDK) is publicly released (Sente on the roadmap).OmiseGO announces MoU with Shinhan Card to further advance Shinhan Card’s digital offerings across its portfolio of payment services and mobile application in today’s growing mobile payments market.May 2018OmiseGO creates a PoC to explore the details of how the improvements of Plasma (Cash) can be incorporated into the OMG protocol.June 2018Neutrino, the blockchain co-working and community space, an initiative of OmiseGO, launches in Japan and Singapore.July 2018eWallet SDK comes out of beta with the 1.0.0-pre0 release.OmiseGO and Status announce technical partnership. Status plans to leverage the OMG DEX by integrating the OMG Software Development Kit (SDK) into their native wallet, allowing us to test out early implementations of the SDK and DEX on a powerful decentralized platform. Read more about the collaboration here.August 2018The OMG Network repo becomes public, including instructions for anyone who would like to download the child chain server and watcher (software which monitors the behavior of the Plasma chain and root chain). Read more here.September 2018OmiseGO shares their DEX design and approach with the public.October 2018Omise Holdings announces that it has raised an undisclosed amount of funding from Japan’s largest private venture capital firm, Global Brain, with participation from 31 VENTURES, CVC arm of Mitsui Fudosan and returning Indonesian venture capital, SMDV. Funding is allocated to OmiseGO as well.Quantstamp completes audit of OmiseGO’s MVP implementation.November 2018Devcon4, the biggest Ethereum gathering of the year takes place in Prague with around 3,000 attendees — representatives of hundreds of projects as well as many thought leaders and independent developers. This year’s conference was particularly energizing and productive; the community was more enthusiastic and hopeful than ever.OmiseGO’s internal testnet is announced to the public and tested for the first time via Hoard Exchange’s Plasma Dog game at Devcon 4. The game is built on Tesuji Plasma (a milestone), which is the first release of the OMG Network and the first implementation of plasma by OmiseGO. Tesuji Plasma’s design is based on Minimal Viable Plasma (MVP).Read more about Hoard’s experience working with the testnet here.OmiseGO announces partnership with MVLchain, the mobility blockchain protocol behind TADA, Singapore’s first blockchain ride-hailing service. The partnership is to develop a POC to verify the suitability and performance of the OMG Network for TADA’s data record-keeping system.December 2018Minimal Viable Plasma testnet is being redeployed following a rebuild. Once all the feature development is completed for MoreVP, the testnet will be upgraded to MoreVP. This is the version that, once OmiseGO is satisfied with it, goes on to become the public testnet. On Plasma, read more here and here, and follow the team as they advance towards external testnet.eWallet version 1.1 is right around the corner. Version 1.1 contains key features needed to begin integrating the eWallet with Ethereum and later plasma, as well as added functionality and user experience improvements. Keep an eye on the eWallet waffle board or the eWallet v1.1 tracker.Communications and CommunityWe are doing more to open up communication between the OmiseGO team and the OMG community, and have looked to our community to determine how we might improve.In July we kick-started our monthly community updates along with technical updates from the eWallet Suite and Plasma teams. If you aren’t able to follow our weekly updates, you can also track the issues we are working on using the GitHub tracker. It is an easy way to stay up to date on our progress. For those who visit our Reddit, you may have seen our weekly AMAs, where we answer the top five questions each week. If you have any questions for the team drop them in this week’s AMA! We hope these initiatives have helped, and are always looking for new ideas. If you have any suggestions or feedback, please let us know.ReflectionsWe’ve experienced both challenges and great progress over the past year. Open sourcing the eWallet was a major achievement. The OMG Network repo becoming public was a big step and even bigger was when we first deployed the child chain for production load at Devcon 4 via Plasma Dog (see November 2018 above).In hindsight and in between, we learned immensely as a tech company that is developing software that aims to enable people to access financial services. We’re operating in uncharted territory and at every turn, there is a lesson waiting for us to learn.We’re grateful for the resilient, innovative and united Ethereum community as well as our working partnerships with Status, Hoard, MVL, Quantstamp and Shinhan Card. We value the connections we’ve made with developers, businesses and other projects in the blockchain space and in the coming year, we will engage more with key audiences.OmiseGO is growing as a company as we move forward with our strategy. We have solid teams of technology and financial professionals, a clear roadmap and plan of action. We’re ready to take on each challenge and look forward to the new year.We will be at the Binance Conference in January. We’re on a panel! Come listen, say hi, ask questions. We’d love to see you.“Look over yonder, hooman. I smells a 2019.”Before we go, we’d like to acknowledge the role community plays in this open-source initiative and what the OMG Network stands for. We extend a heartfelt thanks to the OMG community. 2018 was a year of many ups and downs. We take these learnings forward with us into the new year and strive to do better. Thank you, thank you, thank you for your support. See you in 2019.Happy holidays!OmiseGO TeamCommunity Update - December 2018 was originally published in OmiseGO Network on Medium, where people are continuing the conversation by highlighting and responding to this story.

Update: GiveDirectly’s fin ...
‘Phase 1 Findings: Stateless Payments for Stateless People’You may recall that in March this year, OmiseGO, together with Ethereum Founder Vitalik Buterin, donated the equivalent of $1 million USD tokens to GiveDirectly, to facilitate the transfer of currency directly to people living in extreme poverty. The project that OmiseGO funded is specifically focused on enabling research into the impacts of direct giving to refugee populations.With Phase 1 of the project to deliver large, unconditional transfer of cash to refugees complete, we’re able to draw insights from the research and field work of GiveDirectly to enable our mission to facilitate disintermediation and provide access to financial networks to unbanked populations.A GiveDirectly field officer enrolls a new recipient to receive cash transfers in Kenya. ©GiveDirectlyPilot ProjectPhase 1 of the project was an operational pilot to test the feasibility of delivering large, unconditional cash transfers to refugees in Uganda and gather illustrative evidence of user behavior and impact. This initial pilot is being used to inform a follow-on proof-of-concept in Rwanda and a large-scale third-party evaluation in Uganda, which will deliver cash to an entire refugee settlement (10,000+ households) and produce rigorous quantitative evidence on the social and economic impacts.What sets this project apart is the provision of contextually large, unconditional, one-time direct transfers. The effectiveness of this methodology when compared to other humanitarian aid approaches is proven. For example, it was found in one study that 70% of Syrian refugees elected to receive aid in unrestricted cash over food vouchers.GiveDirectly distributed $660USD each to 4,371 refugee and host households in Uganda, roughly equivalent to one year’s worth of World Food Programme rations. Funds were disbursed to local host communities as well as refugees.Pilot Project FindingsGiveDirectly’s findings from the first phase of the pilot reinforce the thesis of direct transfer of value to achieve positive outcomes on local community development.Most importantly, the pilot proved that large cash transfers to refugees is eminently feasible. Following a locally deployed sign-up campaign and education on mobile pin management, payments were delivered digitally, through mobile money and a local banking partner. Recipients safely received them, with losses to theft and other adverse events at just 0.15% share of total transfers. Economic markets responded, with local agent networks emerging to providing cash out services. New jobs and increased trading of goods and services indicates a strong local economy.Cash transfers provide refugees, one of the most constrained populations in the world, with a unique degree of choice. Around a quarter of the value was used to cover immediate necessities, such as food, clothing and paying off debts. The remaining three quarters went to longer-term investments, such as housing, livestock, businesses or education.Unforeseen circumstances during the pilot demonstrate the benefits of enabling users to maintain agency over how they spend their own funds. Just before receiving the transfers of cash, refugees had their farmland repossessed by the Ugandan government in order to house new arrivals of refugees in the region. The proportion of the refugee population engaged in subsistence farming and commercial farming fell drastically. Unconditional cash transfers, rather than predetermined aid solutions such as food vouchers, allowed people to adapt and choose how to meet daily needs and diversify income sources.If unrestricted direct cash transfers were the default mode for humanitarian assistance, research suggests that their share of the humanitarian budget would be roughly four times bigger.The full report on activities and outcomes from GiveDirectly is available here.Implications for OmiseGOOmiseGO’s donation contribution is going towards a larger scale project to deliver cash to an entire refugee settlement in 2019 which will be followed by a rigorous external evaluation of impact.The research and evidence from GiveDirectly’s work is extremely important to forward the vision of delivering mobile financial transactions at scale for financial self-sovereignty and understanding user adoption prerequisites and behaviors in local contexts.We are living in the highest levels of displacement in human history. An unprecedented 68.5 million people around the world have been forced from home. Among them are nearly 25.4 million refugees, over half of whom are under the age of 18. There are also an estimated 10 million stateless people who have been denied a nationality and access to basic rights such as education, healthcare, employment and freedom of movement. The availability of financial networks to access credit for housing, services and businesses is crucial. In this sense, accessible financial systems are key to unleashing the vast potential of the urban poor to improve their living and working environments and livelihoods and addressing human inequality.OmiseGO is deeply appreciative of the on-ground efforts and open research of GiveDirectly. We will continue to utilize the findings of GiveDirectly’s work in the field to inform our understanding of mobile money network adoption in underserved markets, education of local communities for mobile money adoption, and cash-out behaviors in given contexts to reach end users.Call To ActionAgain, we would like to use this opportunity to raise awareness of GiveDirectly’s efforts and invite the OMG community to participate.For financial contributions, GiveDirectly accepts ETH or ERC20 tokens to this Ethereum address.We also welcome engagement from development sector experts and local community groups, especially in Southeast Asia, to help inform market engagement and effectively serve local communities.Blog Credits:GiveDirectly Team for inputs.GiveDirectly blog: https://www.givedirectly.org/blog-post?id=8598277768732857358Full report: https://givedirectly.org/pdf/CashTransfersToRefugeeCommunitiesWhitePaper.pdf United Nations World Food Programme, ‘Food — Restricted Vouchers or Unrestricted Cash?
