ICF Update — Sept 7th

ICF Update — Sept 7thToday marks two weeks since our update about the Q2 funding recipients. We’d like to use this time to begin a new bi-weekly update where we can highlight some of the more exciting activities that took place at the Interchain Foundation. This will include some check-in meetings that occurred with various recipients as well as general meetings and goings-on that members of the Interchain ecosystem might find interesting and informative. If any of the updates are especially relevant to what you are working on feel free to drop us a line at Applications ClosedAugust 31st was the last day to submit Q3 funding proposals. The application form is still open at but all applicants until November 30th, 2020 will be considered for Q4 2020 funding opportunities. Now we will begin the process of reviewing and providing feedback with applicants until the Board of Management comes up with a final list of proposals. These will be reviewed by the Technical Advisory Board who will provide comments on the proposals. Afterwards the proposals and comments are submitted to the Foundation Council which will review and ultimately decide on the outcomes of the various proposals. If all goes well this process should be the second complete cycle of the new funding program and should be complete by October 1st, 2020.Nomic Check-InWe had our regular check-in with Matt Bell and Judd Keppel from building a Bitcoin sidechain. They’ve been developing a new rust based SDK called Orga utilizing Tendermint via ABCI in order to build performant applications. They’ve been active in the Cosmos-SDK issue “What do to about IAVL” where use of merk, their rust based merkel key/value store, may end up playing a vital role in an IAVL solution. This could furthermore increase the portability of IBC across codebases.Althea UpdateAlthea has been working with the newly founded UniFi DAO in order to expedite the Peggy bridge delivery schedule. The DAO successfully raised 30,000 ATOMs that will go towards onboarding new developers and ensure the codebase becomes production ready ahead of the original schedule as funded by the ICF. Integrating the Peggy module directly into the Cosmos Hub is an exciting proposal that is gaining momentum and community support that would allow transfer of tokens from Ethereum mainnet onto the Cosmos Hub and the greater Internet of Blockchains. If you’re interested in following along, follow Althea’s blog, join the Peggy discord channel or UniFi DAO telegram group.Akash IBC Relayer MaintenanceAkash network finalized a service agreement with the ICF to support maintenance of the IBC relayer in golang. This was the relayer initially built by Jack Zampolin and Iqlusion during Game of Zones. Jack recently became VP of Product at Akash and will oversee maintenance as well as a few new features in order to be the primary relayer during the Stargate upgrade of the Cosmos Hub. Join the Stargate Discord channel to follow along.Web3 & ICF Co-Funded Simply VC’s PANIC Validator Monitoring SuiteSimply VC recently finalized a service agreement with the ICF to support the next iteration of the PANIC Validator Monitoring service. This work was co-funded by Web3 Foundation in order to ensure that Substrate validators are supported by the suite as well. The current version of PANIC requires a relatively technical installation and interface process while the new version is a web based, user friendly version that offers a variety of insights and integrations to give validator operators and network data providers deep insights into the state of various proof of stake networks.NFT & Metadata Working Group Led by ixo & Persistence OneLast Friday, September 4th, was the kick-off call for the new NFT & Metadata working group being led by ixo and Persistence One (video here + passcode “GF+aP4EE” & blog post here). They recently finalized a joint service agreement with the ICF to do spec design and development of the NFT Module as well as a new Metadata module that will allow a rich system for asset introspection and management of capabilities across blockchains. That means not only will you have basic NFT information available like Name, Image and URI but also provide a format for information like whether the NFT can be transferred, burned or sold. This metadata module should be furthermore useful outside of strictly NFT contexts as a standalone module that can augment any number of other modules and their capabilities. The call was joined with presentations by NFT users IRIS Network, Regen Network and Left Gallery. To take part in the discussion join the discord channel on the Cosmos Community Discord.Lunie Notification SupportWe recently had a check-in call with Jordan Bibla, CEO of the Lunie Wallet for Staking and Governance. They’ve been hard at work adding support for Polkadot as well as incorporating a new notification system. This feature is really great, I tried it out with an account I use for testing and saw that one of the 0% commission validators I staked too were incrementing the commission rate on a daily basis. I would have never been monitoring this so closely and their system made it immediately apparent.Left Gallery Pair Programmingleft gallery’s Harm van den Dorpel and Alberto Granzotto, previously of Ascribe and BigchainDB stopped by the Interchain GmbH offices for a pair programming session with Billy Rennekamp and Sam Hart to kick off their development of the Cosmos SDK interaction of They’ll be working on a semi-custodial module system to allow delegated management of certificates of authenticity for digital artworks.Dystopia Labs and 2020 Cosmos ConferenceDystopia Labs finalized a service agreement this week with the ICF to begin work planning the 2020 Cosmos conference to take place Sat Dec 12th — Sun Dec 13th. We’re excited to be working with Hsin-Ju who has done fantastic work on previous events DeFi Discussions, Trust-Less 2020 & Liquidity2020. Keep an eye out for more details as this work develops and we finalize the speaker list! You can already ensure you stay up to date by signing up at for catching up on our first of (hopefully) many regular updates. We’ll be working on the format to keep it brief but informative. If there are things you’d like to hear more about feel free to reach out to or ping us on Twitter at @interchain_io.See you in 2 weeks!ICF Update — Sept 7th was originally published in Cosmos Blog on Medium, where people are continuing the conversation by highlighting and responding to this story.

Interchain standards for No...

Technical working GroupWe are excited to announce the formation of a new technical working group with a mission to develop Interchain Standards for Non-Fungible Tokens and Metadata.You are invited to join the series of 6 NFT+Metadata working group calls, which will take place every 2 weeks, starting Friday 4th September at 08:00 UTC. Sign up here!We believe Interchain Standards can build on established Internet standards, to gain broad adoption and promote interoperability between blockchains, as well as with legacy Internet protocols. These developments should be a great complement to the Inter-blockchain Communication Protocol (IBC), enabling cross-network discovery, authentication, control and usage of NFTs and their Metadata resources.This open collaboration was initiated by the Interchain Foundation and will be facilitated by ixo (The Internet of Impact) together with Persistence One (Protocol Powering Institutional DeFi).You are invited to join the series of 6 NFT+Metadata working group calls, which will take place every 2 weeks, starting Friday 4th September at 08:00 UTC.The first call will introduce this work and we will kick off with a discussion of use-cases.Participation of the Cosmos community is encouraged in the “nft-and-metadata” channel in the Cosmos’ Discord. Work in progress and requests for comments (RFCs) will be posted in the Cosmos SDK Modules Github repo.The first priorities for this group are to get collaborators onboard and to collect NFT and Metadata use-cases, against which the standards and reference implementations can be calibrated. Please spread the word to projects and people who are likely to be interested and have something to contribute. Also let us know of relevant past or current initiatives we should be aware of, so that we build on prior art and coordinate efforts across blockchain and internet communities.Our working hypothesisTokenizing real-world resources is a critical enabler for the digital economy. This is also essential for transitioning the world to more accountable, sustainable means of producing and using resources.It is now technically feasible for any uniquely identifiable physical world resource — whether tangible or intangible, to be represented in a non-fungible tokenized format. Non-fungible Tokens (NFTs) have powerful features, such as embedded rights, provenance and verifiability. The range of canonical use-cases and lists of potential features of NFTs and Metadata are growing.However, there is not yet a fully interoperable NFT standard for tokenized resources to be virtually addressed, described, authenticated, controlled or exchanged across blockchain networks and through the Internet.This Interchain project will contribute a set of interoperable open standards and reference software implementations for NFTs and Metadata. We will demonstrate how resources can be tokenized and used across networks, for a set of canonical use cases, provided by the Cosmos community.Our premise is that a standard for tokenizing resources must be based on well-established semantic Internet Standards, which can be upgraded using stateful data graphs.The NFT standard will be a special class of Uniform Resource Identifier (URI). Metadata standards will be based on the Resource Description Framework (RDF), for which various encodings (file formats) are possible. Ideally, the NFT and Metadata standards should be backward compatible with standard resources which are already available on the Internet.Both the NFT URI and its Metadata RDF encoding will be defined as nodes in a stateful graph. This should help establish the provenance of linked real-world resources. Encoded resources can be dereferenced for information that expands the graphs of data linkages between related resources and resource schemas. Using this linked-data format could further enrich NFT Metadata through relationships with other resources, thereby increasing the utility and value of both the NFT and its metadata resource. There is strong potential that this will increase the value of related real-world resources.Outputs of the projectWe will produce technical standards for NFTs and Metadata, which have undergone peer review by community stakeholders and experts.Reference implementations of these standards will be implemented in code as Cosmos SDK modules.A basic UI will be built for exploring NFTs and to provide verifiable displays of NFT Metadata.Client library support will be added.Guidance will be provided on how to use NFTs with the Inter-Blockchain Communication Protocol.In early 2021 we will provide developer tutorials and invite you to demonstrate your own use-cases for NFTs and Metadata, built on these new Interchain standards and the open-source software components.Please do get involved now, to help progress this exciting development. Your contributions will be welcomed and fully acknowledged!About the project leadsThis open collaboration will be spearheaded by Persistence One and ixo, working in partnership with funding and technical support from the Interchain Foundation. The ixo team will lead research and development of the technical standard for NFT Metadata, demonstrate a user interface for verifiable displays of NFT metadata and introduce a cross-chain decentralized identifier (DID) resolver. The Persistence One team will lead the development of an interface standard and reference Cosmos SDK modules for NFTs, with IBC and client library support.The mission of Persistence One is to facilitate seamless exchange of value around the world to increase the speed and efficiency of cross-border trade and financing to close the $1.5 Trillion financing gap. The need for a solution like Persistence One has never been clearer. A sizable and increasing amount of institutional capital and emerging Stablecoins are looking to generate yield. There is an ever-increasing need for MSMEs traders and businesses to access financing.Persistence One matches these needs by bridging the gap between Traditional Finance and DeFi.ixo is building the Internet of Impact as an essential digital and data technology infrastructure for Sustainable Development and the new world Impact Economy. This will deliver powerful new tools for sensing and responding to verifiable changes in the state of the world. Capital can be programmed with incentives to achieve positive future-state outcomes. Webs of trust connect people, machines and software agents to share intelligence, coordinate local actions and deliver impacts with precision.Join the discussionCosmos Discord: look for “nft-and-metadata” group, under the “modules” sectionInterchain standards for Non-Fungible Tokens and Metadata was originally published in Cosmos Blog on Medium, where people are continuing the conversation by highlighting and responding to this story.

Announcing the Cosmos Commu...

Greetings Cosmonaut 🖖,Earlier this year, we announced the recipients of a Cosmos Community Contributor Grant in Q1. For a bit of background behind this “grants program”, the idea came around late last year when Adriana Mihai came to me with an intriguing problem. The problem was this — we were missing good schemes that actively rewarded people for building up their parts of the Cosmos community. In an effort to gather our thoughts and identify those who had been doing some solid work in all areas pertaining to development, research, building in general, and running meetups—all without pay that whole time during year 1 of mainnet, mind you—we put together a spreadsheet with names of Cosmos contributors and what they did. Then we passed that sheet over to Interchain Foundation in hopes of getting something to fund that list of names with.After months of back and forth with the foundation lawyers, the ICF ended up deciding against sending direct contributions to recipients who were not part of their greater grants application process. It’s important for them to be conservative in the operation of the foundation where moving slow is a feature and not a bug. They did, however, allocate some funding for specific deliverables—Today in Cosmos translations—as well as budget for meetups. The need, however, to support more types of work beyond just translations and hosting meetups remained unsatisfactorily met.Ultimately, we ended up breaking down what each organization was good for, what each organization was good at, and forming a program that balanced those considerations with the needs of the community.The ICF is great at recognizing important research needs that cater to the longevity of Cosmos. They’re good as a source of funding for amounts that range from “under $10k to over $100k, depending on the scope of the project” according to the ICF. Their mission is to pursue the ends of an Internet of Blockchains — a very broad and sweeping one with a very long-term outlook. Read the Q2 funding recipients post here for a better sense of what types of projects ICF funds.In contrast, Tendermint keeps a much shorter telescope that caters to the short to medium-term needs of the network — specifically, the needs of the Cosmos Hub and the ecosystem of ATOM holders. Tendermint is fantastic at recognizing important practical integrations that are needed today in order to bridge the gap between users and Cosmos. Tendermint is able to move fast while giving smaller grants to the tune of $50 to $5000 — microgrants, if you will.All this work having been done in the background culminates today in an official Cosmos Community Contributor Microgrants program that we are very excited about and finally opening up to the public for applications. (If you have a more catchy, less lengthy name for this program, I’m all ears.) As we enter the 2020 crypto bull market, I expect to receive a tidal wave of new blood propelling themselves past the Bitcoin moon and into Cosmos out of a renewed interest in this rapidly warming market. As such, this program will allow all new and existing Cosmonauts to apply for, submit contributions, and get microgrants for in any one of these categories:This is meant to be a complementary measure until the Stargate upgrade is deployed on the Cosmos Hub. What’s lesser known about Stargate is that it includes a feature in Cosmos SDK that will allow anyone to send ATOM to the community tax pool and supplement the total funds such that governance will be able to review and fund future Cosmos community contributions with its bigger pool of funds. But before this feature is on the Hub, this program will act as the main pillar to fund community contributions and act as a framework to inform future contributions that will ultimately land on the Cosmos Governance table for the broader community to fund.🌟 Join the 🚀 Space Program 👉 👈🌟 See what else is happening in the 👉 👈And without further ado, I’m proud to announce Q2’s recipients—in no particular order.👨‍🚀 Q2 Community Contributors 👩‍🚀🗒 Will your name show up on next quarter’s list? ⭐️🚀🤠 Space Cowboys/girls go here 👉 👈Live long and prosperAnnouncing the Cosmos Community Contributor Grants Recipients of Q2 was originally published in Cosmos Blog on Medium, where people are continuing the conversation by highlighting and responding to this story.

Open-sourcing the Cosmos Ne...

From the very beginning, the Cosmos community has been at the forefront of open-source technology by spearheading the development of toolkits and protocols like Inter-Blockchain Communication (IBC), Tendermint Core, and the Cosmos SDK.As proponents of open-source software, we, at Tendermint, value transparency and the benefit of an extra set of eyes on our work. In this spirit, we have worked hard to build the free and vibrant developer community we see today — a place where everyone is welcomed and empowered to collaborate, discuss, and sustain knowledge transfer.We take pride that through our initiatives, we have inspired others to follow our lead and open-source their work, bringing us closer to the vision of Cosmos — a decentralized, secure, and sustainable ecosystem of interoperable networks.Today we make another step towards our common goal by open-sourcing the Cosmos website, 🚀The role of the Cosmos websiteSince its inception in 2017, the Cosmos website’s primary purpose has been to introduce the vision of the ‘Internet of Blockchains’ to a worldwide audience of developers, token holders and blockchain enthusiasts. It has played a critical role in attracting numerous developers, communicating the benefits the Cosmos architecture provides, and introducing them to the tools they need to start building Cosmos applications.In the last two years, the website has had over 2.7 million page views and over 420k visitors. Fundamentally, it has been the gateway to the ever-expanding Cosmos ecosystem we see today. ✨Number of pageviews and visitors, and top pages on — June 2018 to June 2020High-level visitor stats for — June 2018 to June 2020Open-sourcing the websiteAt Tendermint, we believe that we can create a more transparent and accountable world through open, distributed, and interoperable networks. Our work orbits around these core principles while we endeavour to provide the necessary tools to empower those who strive for the same goals.As our developer community has matured, they have provided valuable feedback and ideas to more effectively communicate the Cosmos vision. By opening up the source code to the Cosmos website, we now have a new platform to converge these ideas and address feedback in an open and transparent manner, ensuring everyone’s voice is heard.Tendermint will continue to shepherd the design and development of Cosmos websites, with support from the Interchain Foundation. The Tendermint design team is committed to building a website that will better reflect and celebrate the true nature of the fast-growing ecosystem and its thriving community. This is the first step towards that goal.What exactly have we open-sourced?Publishing our source code on GitHub gives us a chance to leverage all the excellent tools for collaboration and continuous integration that our community has to offer.At a glance, here is the current state of things:The repository of the entire website front-end has been open-sourced on GitHub.There are still some pieces yet to be open-sourced, like our data sources for events, articles, projects, and our source files for design assets. These will be made publicly available in the next few phases of development.The Cosmos brand is still trademarked by the Interchain Foundation, and some visual assets are available for use. Please be sure to adhere to the guidelines for Cosmos trademark usage.How can I contribute?We are excited to accept contributions, but bear in mind there will be many changes ahead with a full website redesign project currently underway (outlined below). In the interim, we are welcoming contributions such as:Suggestions for improving communication in our copywriting.Identifying and fixing broken links.Updating out-of-date or inaccurate content.Updating links and descriptions of projects and tools.Cross-browser bug fixes — please note that we only intend to support the latest versions of major browsers.Check out the repo on GitHub to create pull requests and issues for the above.What comes next?✨ cosmos.networkOpen-sourcing is just the first step of a momentous journey for the Cosmos website. The Tendermint design team is hard at work designing a new website with a brand new visual look-and-feel and refresh of the brand identity. Check out the new Stargate website to get an idea of where things are headed, as this website will serve the basis for development of the upcoming redesign.Moreover, with an overhaul of the site structure, we’ll be introducing new and updated content, so make sure to keep an eye on the team’s progress in the new repository for the Stargate website. Meanwhile, we are establishing processes for community contributors to provide submissions of the following:Cosmos community eventsProjects (Wallets, zones, block explorers, visualizers, tokens etc.)Development tools, modules, integrations etc.Articles, videos, and other relevant Cosmos mediaTutorials and guides⚛️ hub.cosmos.networkIn order to better inform existing and future ATOM token holders as stakeholders of the Cosmos Hub, we are nearing the completion of a new website for the Cosmos Hub. We hope that this new website will provide token holders, with all the information they need to start their Cosmos journey. Everything from token acquisition, staking information, wallets, explorers, validators will be covered — stay tuned for more.🌐 parallel with the redesign of the Cosmos website, we’re also compiling more accurate, comprehensive, and up-to-date data for projects and tools in the Cosmos ecosystem.This new data source will exist in a public repository on GitHub (cosmos/awesome), which will surface the criteria for submitting updates and new projects for review. This development is underway, in collaboration between Tendermint and Interchain GmbH.Get involvedWe want to hear your thoughts! We’re creating a new channel specifically to discuss the design and front-end development for the various Cosmos websites.

Launchpad — A pre-stargate ...

Launchpad — A pre-stargate stable version of the Cosmos SDKIntroducing Launchpad, a release series of the Cosmos SDK that aims to be a stable milestone for Cosmos SDK-based blockchains to use until they upgrade to Stargate.Stargate, the biggest upgrade to the Cosmos ecosystem, is coming later this year. Most of the Stargate upgrades will affect the Cosmos SDK in substantial ways, making the upgrade process more involved than for previous versions. To make this process easier for module developers, blockchain builders and client providers, we are releasing a version series of the SDK called Launchpad. It will allow SDK developers to enjoy a stable version of the framework until they are ready to upgrade.What it ContainsLaunchpad will be released as v0.39.x (starting with v0.39.0) of the Cosmos SDK. In short, it is a stabilized version of v0.38. The main addition is a fix to the IAVL pruning functionality, following the introduction in v0.13.0 of a bug whereby the state was flushed only periodically. The fix reverts IAVL to its pre-v0.13.0 behaviour where every state is committed and flushed to the disk. Launchpad also contains a number of small improvements and performance fixes. To see all the updates in v0.39.0, see the changelog.Note: If you are currently using Cosmos SDK v0.37.xor v0.38.x for your project, you should plan to upgrade to either Launchpad (v0.39.x) or Stargate, given that they contain important stability fixes for issues introduced in the aforementioned version.A migration path to StargateStargate will introduce significant breaking changes to the core SDK framework (most notably the switch from amino to protobuff as the main SDK codec) as well as many of the most widely used modules. It will also introduce new features and modules such as light clients and the upgrade module that will significantly affect the way people run full-nodes and interact with them. As a result, the upgrade process to Stargate will be more challenging than usual for SDK-based projects. To help smooth this process, the Stargate team will provide well-tested and documented migration paths from the Launchpad releases to the Stargate release.Importantly, the Launchpad series will be maintained even after the release of Stargate. Intended to be a stable release series, no new features will be introduced, but additional stability fixes and non-breaking upgrades may be incorporated if needed. This will allow projects using the Cosmos SDK to have all the time they need to upgrade to Stargate.How to upgrade to LaunchpadThe first version in the Launchpad series is released as v0.39.0 of the Cosmos SDK, a breaking upgrade from previous versions. Be sure to check the changelog in order to be aware of all the changes you might need to take into consideration when upgrading your chain to Launchpad.As for upgrading full-nodes, you can find a guide here.Next StepsGoing forward, Launchpad will be primarily managed by Ethan Frey (Confio), Cory Levinson (Regen Network) and Alessio Treglia (Tendermint). It is already being used in testnets by IRISnet, Ethermint,, IOV and more.If you would like to suggest any addition for following releases, please open an issue on the Cosmos SDK repository with the 0.39 Launchpad tag. If you have any other questions, feel free to join the Launchpad channel on the Cosmos Community Discord.Launchpad — A pre-stargate stable version of the Cosmos SDK was originally published in Cosmos Blog on Medium, where people are continuing the conversation by highlighting and responding to this story.

Preparing for IBC 1.0

by Interchain GmbHIntroductionThe upcoming Stargate upgrade will include version 1.0 of the Inter-Blockchain Communication protocol (IBC), the mechanism for interoperability between heterogeneous chains, which forms the connective substrate for the Cosmos Network. IBC has been in design and development since the release of the original Cosmos whitepaper. In suitable fashion for a technical interoperability protocol, interoperability between many organizations and individual contributors has been essential in bringing IBC to where it is today — Tendermint, Agoric, Informal Systems, Chorus One, Iqlusion, Interchain GmbH, and the Interchain Foundation have all contributed resources & personnel to the design, specification, and implementation of IBC. Many community contributors outside of those organizations have found bugs, submitted specification proposals, and provided invaluable quality assurance testing for the software. The 1.0 release of IBC is the culmination of years of diligent work by these organizations & individuals, but it is also the beginning of the next chapter in the trajectory of the Cosmos Network, and the inflection point at which the driving force behind protocol development & adoption must shift from a relatively tight-knit coalition of firms to a much wider community of blockchain developers, proof-of-stake validators, and protocol users.This blog post outlines what the 1.0 release of IBC will consist of, enumerates the expected sequence of steps for testing & deployment of IBC as part of the larger Stargate upgrade process, briefly catalogs ongoing IBC-related work which is not formally part of the 1.0 release process but will be of interest soon, and sketches a few nascent ideas for the future development of IBC after Stargate & the 1.0 release, some of which will also be outlined in greater detail in a future post.Ingredients for the 1.0 IBC releaseIBC has been developed “specification-first”, meaning that we first designed & wrote down a complete, canonical specification of the abstractions & logic utilized in the protocol before writing any code. The specification is designed to provide a sufficient level of detail so that properties of the protocol can be reasoned about in the abstract, and so that implementations in different languages or frameworks which are faithful to the types & procedures in the specification will correctly realize these properties and interoperate seamlessly with each other. The IBC specification is available in full form on Github and in condensed form as a paper. The 1.0 IBC release will include a canonical 1.0 specification version, which can be implemented by any blockchain for specification-compliant IBC support.The first implementation of the IBC protocol has been developed in Golang using the Cosmos SDK. This implementation adheres to the aforementioned specification and includes dynamic capabilities for runtime port & channel permission management, Tendermint light clients for interoperation with any Tendermint blockchain, solo machine clients for interoperation with solo machines identified by a public key, a generalized Merkle proof system for integration with different back-end blockchain data stores, and an ICS-20 module for cross-chain fungible token transfer. If you are interested in playing around with the Go code or integrating it into your blockchain, check out the documentation. The 1.0 IBC release will include a specification-compliant 1.0 IBC implementation in the Cosmos SDK, which can be imported directly by any Cosmos SDK for plug-and-play IBC support.In order to facilitate data transport between sovereign chains, IBC requires the existence of off-chain relayer processes, which monitor the state of chains for outgoing packets and submit them to the appropriate destinations. Anyone with accounts to pay transaction fees and the ability to monitor state & submit transactions can be a relayer, and in order to automate the logic involved, we have developed a Golang relayer which can automatically set up light clients, run the handshake process to create connections & channels, and scan & relay IBC packets from one chain to another. The 1.0 IBC release will include a specification-compliant 1.0 Golang relayer release, which can be easily configured & operated by anyone wishing to relay IBC packets.IBC pre-flight check sequence ✈️Interchain GmbH is currently in the final steps of testing & finalizing the Golang IBC implementation in the Cosmos SDK, with a particular eye towards ensuring that future upgrades, both of blockchains utilizing the IBC protocol and of the IBC protocol itself, can proceed smoothly with minimal disruption to users. Once complete, this work will be released in Cosmos SDK v0.40, in conjunction with Tendermint v0.34, as described in the Stargate Upgrade Proposal.The Stargate upgrade bundles together a lot of changes, and it will likely be necessary to go through several release candidates and intensive sequences of testnets in order to ensure that the software is ready to deploy to production. The first Stargate testnets will focus mostly on preparing users & integrated services for the protobuf encoding changes, but zones and potential relayers will be able to individually start preparing for IBC integration and test out the release candidate software if they wish. A public bug bounty program will be operated for any bugs found in the aforementioned IBC specification & software release candidates. Subsequent Stargate testnets will specifically focus on multi-chain IBC interoperation. Zones that wish to support IBC are highly encouraged to participate. Finally, the Stargate testnet sequence will test the non-disruptive in-place upgrade sequence using the Cosmos SDK upgrade module and ensure that it does not disrupt in-progress IBC operation in a multi-chain topology.Once stable software releases are achieved, and all tested features & sequences operate smoothly, a final upgrade proposal can be prepared for the Cosmos Hub which will execute a halt-restart upgrade to atomically switch from the current software to the Stargate release at a set height, similarly to how previous Hub upgrades have been performed. Stakeholders should carefully evaluate any such proposal, test the software themselves, and make an informed judgment as to the readiness of the software before voting.If the Cosmos Hub decides to pass the final Stargate upgrade proposal, clients, connections, and channels will be enabled on the Hub along with the upgrade, facilitating set-up and testing with other chains that have also integrated the IBC implementation. Initially, ICS-20 cross-chain fungible token transfers will be disabled, in a similar fashion to how transfers were initially disabled when the Cosmos Hub first launched. Once Hub stakeholders are confident that the protocol is secure and safe to use, a second parameter-change proposal will be able to activate cross-chain transfers, after which tokens will be able to be sent to the Hub from any IBC-compatible chain, and from any IBC-compatible chain to the Hub. Because of the ability of the IBC protocol to safely handle dynamic chain topologies, it is not necessary to specify ahead of time any particular list of chains — the process of setting up a connection and a channel for token transfers is permissionless and does not expose any users who choose not to use that connection or channel to the fault risk of the counterparty chain.At this point, the possibilities for interoperability are dependent not on the Hub or on the Stargate upgrade process, but on the integration of IBC by other chains, which they can do at their own pace, electing to use the Cosmos software implementations or not as they prefer. IBC is experimental, alpha software, and should be integrated & tested carefully before deployment. All usage of IBC is at your own risk. We encourage chains to ensure that user-facing software such as wallets or browser extensions clearly describes the risks and security model to users when performing any cross-chain operations.Ongoing IBC-related workWe have intentionally elected to keep the scope of the Stargate release, already a large coordination effort, no larger than absolutely necessary, but a lot of fantastic IBC work is proceeding in parallel on independent timelines. This is by no means an exhaustive list.Informal Systems is working on formal verification of the IBC protocol, including handshakes, packet send & receive logic, light client behavior, and the relayer algorithm, with the model checker TLA+Informal Systems is also working on a complete IBC core protocol implementation and a complete IBC relayer implementation, both in RustConfio is working on an integration of IBC handler logic into their WebAssembly smart contract system, which runs on the Cosmos SDK and comes with JS client supportChainapsis is working on the specification and implementation of the interchain account protocol, which will allow an account on one blockchain to control an account on another blockchain using IBCChorus One is working on a Tendermint light client and Substrate light client, both in Rust and designed for compilation to WebAssembly & usage with IBCAlthea is working on Peggy, a bridge from the Ethereum network to a Cosmos SDK-based blockchain which in conjunction with IBC will bridge the Cosmos & Ethereum ecosystemsAgoric is working on the integration of IBC into the Agoric platform for secure smart contracts written in JavascriptChainSafe is working on the integration of IBC into Ethermint, which will allow EVM applications to run on Tendermint chains and connect to the Cosmos network over IBCCdot is working on an implementation of IBC in Substrate (Rust), a GRANDPA client, and maintaining Chinese translations of the ICS specificationsAkash is helping with maintenance of and working on features for the Golang relayerNomic is working on a Bitcoin two-way peg / sidechain & Tendermint light client in JSToo many teams to list are helping test the software in incentivised testnets and find bugs prior to launchFuture directionsThe 1.0 release, in conjunction with expected additional software releases later this year, marks an inflection point in the trajectory of IBC development: going forward, the successful adoption of IBC as an open, permissionless standard will be determined by the choices of sovereign blockchains, operators, and users. The core protocol is just the beginning — interoperability between applications over IBC will also depend on application-level standards describing particular packets, data encoding, and processing logic (such as ICS 20 & ICS 27). Additional implementations of IBC in different languages & frameworks will reduce the barrier-to-entry to the ecosystem and allow a diversity of heterogeneous use-cases to proliferate. New light clients & state verification procedures will enable different consensus algorithms and state machines to speak IBC. Protocol stacks on top of IBC, such as cross-chain validation, will provide advanced functionality and new security models composed of the primitives provided by the core protocol. Post-1.0 protocol versions may incorporate alternative causal ordering guarantees, new channel types, and automatic multi-hop routing. Future work on IBC will necessarily be a collective effort, emergent from a process of rough consensus-building and resource contributions by a multitude of organizations and individuals. We can’t wait to see what you’ll build.You can follow IBC progress on Github, Twitter, Discord, or here on Medium.Preparing for IBC 1.0 was originally published in Cosmos Blog on Medium, where people are continuing the conversation by highlighting and responding to this story.

Cosmos Stargate Upgrade Ove...

Introducing Stargate, the largest Cosmos upgrade yet. Stargate will enable higher transaction throughput, cross-chain transactions, accelerate UI development, and so much more.At a GlanceJoin the Cosmos Stargate announcements channel!If you’re running a block explorer, wallet, exchange, validator, or any other service (eg. custody provider) that depends upon the Cosmos Hub or Cosmos ecosystem, you’ll want to pay attention, because this upgrade will involve substantial changes.Inter-Blockchain Communication (IBC)- cross-chain transactionsProtobuf Migration — blockchain performance & dev accelerationState Sync — minutes to sync new nodesFull-Featured Light ClientsChain Upgrade Module — upgrade automationHelp us to get the word out -this is a major leap for the Cosmos Network and we want everyone on board 🚀Cosmos Hub to Lead the Stargate UpgradeIn December 2019, the Cosmos Hub’s only major upgrade delivered new power to ATOM stakers by way of governance: parameter changes and community spending. Prior to the Cosmos Hub 3 upgrade, the chain had to be halted to change economic parameters, which can now be changed via governance proposal. Importantly, funds from the community pool can be spent via governance proposal, a powerful tool to accelerate Cosmos Hub development.Currently, we have a stable network with a strong set of Cosmos Hub validators. We have a functioning governance system with strong participation, and we have used our community pool to fund two projects. However, the Hub is still independent from the rest of the Cosmos ecosystem, and the Hub was designed to connect the Cosmos ecosystem together.The next step is the Stargate upgrade, coming later this year. Stargate will improve the Cosmos ecosystem in a few major ways. Perhaps one of the most well-known benefits being delivered in Stargate is the ability to connect Cosmos-based chains together using Inter-Blockchain Communication (IBC), and the Cosmos Hub will be leading the way for the Stargate upgrade.If you’ve been following the Cosmos ecosystem lately, you have likely seen an explosion of ecosystem activity in preparation for the launch of the much-anticipated IBC protocol. Stargate will usher in more than just IBC.Stargate OverviewThe Cosmos ecosystem will look to Cosmos Hub governance to vote on the features of the largest Cosmos upgrade yet. Here are the primary features:Inter-Blockchain Communication (IBC)The ability to exchange transactions of value and data across compatible chainsProtobuf MigrationAccelerates front-end development and 10x to 100x better blockchain performanceA new node can synchronize 200x faster, participating in consensus in minutes rather than daysChain Upgrade ModuleEnables validators to upgrade the chain software asynchronously in minutes rather than an hour or moreIn essence, this launch will complete the roadmap laid out in the Cosmos whitepaper, as discussed by Zaki Manian ( Iqlusion). Here’s a recent Q&A: Connections via IBCCosmos’ flagship, the Inter-Blockchain Communication (IBC) protocol, is set to launch with the Stargate update. IBC will mark the emergence of a much-anticipated interoperable Cosmos network: the ability to securely and trustlessly exchange data and token value across sovereign chains that support IBC. That means that 1) tokens and 2) data will be exchanged across different blockchains, and we anticipate that the Cosmos Hub will be the first to secure those cross-chain exchanges.New to IBC? Here’s a simple explainer. Want to dive deeper? IBC is being addressed in a number of spots, and here are a few places to start:IBC is what will take siloed, Cosmos-based blockchains and bring them together to make an ecosystem called the Cosmos Network.If you plan to support tokens beyond the Cosmos Hub’s ATOM with your wallet, exchange, block explorer or other application/service, check out the IBC security model (demonstrated extensively during Phase 3 of Game of Zones) in order to effectively balance novelty and safety for your users.The Cosmos Hub will strive to be the most secure and reliable hub that links them all together, with its battle-tested validator set and with the economic power of the ATOM. A truly decentralized Interchain should have no single point of failure, and hubs like the IRIS Network will also route interchain transactions.Accelerating Performance & User Interface Development via ProtobufIt could be that IBC has stolen all of the attention, or perhaps the name “Protobuf Migration” is not nearly exciting enough, but the Protobuf Migration will do a number of key things for Cosmos blockchains. Beginning with the Cosmos Hub, we’ll see significant improvements to performance, compatibility, interoperability, operability and developer ease-of-use. What does that mean?A better Cosmos future with ProtobufApplications will be way faster, gas costs will be much lower, and there will be more transactions included in each block. Applications will be more reliable and easier to create, supporting a lengthy list of programming languages. Protobuf is expected to clear the biggest bottleneck in Cosmos-one that touches every layer. Clearing this bottleneck will enable the teams working on Cosmos to see what else can be improved going forward.A performance increase of one or two orders of magnitudeWe expect transaction throughput of the Cosmos Hub (and others that upgrade) to increase by 10x to 100x. This will be very important for the Cosmos Hub to handle an ever-increasing volume of cross-chain transactions. It also makes it easier on the nodes that run the network. Around 50% of CPU time when running `gaiad` is currently spent in the encoding and decoding logic, and that’s about to change, thanks to the migration to Protobuf. And there’s more.Reliability, composability, and better UIsProtobuf will introduce a standard for composability. That means easier development of reliable front-end user interfaces (UIs) that work together with other UIs. Current UIs need an intermediate process to read/write blockchain data, which makes things slow and unreliable. Not only will web apps (in Javascript) be able to communicate directly with a Cosmos node, applications using any of the many Protobuf-supported languages will do this as well. Protobuf will be critical to attracting user interface developers who want to make great new Cosmos apps.New nodes up and running in minutes via State SyncAt 6 or 7 seconds per block, Tendermint makes new blocks very quickly. That’s great for blockchain performance, but challenging for participants that need to synchronize a new node, which can take days. This is a big problem for a validator operator that needs to replace a failed validator. The current workaround is downloading a public snapshot, which makes syncing much faster, but it’s a security risk for the validator and the network. State Sync will enable a Cosmos node to be up and running securely within minutes, not days.Full-Featured Light ClientsAccording to Zaki (Iqlusion), Tendermint’s light client security model allows full nodes to bootstrap themselves securely without waiting days to sync all past state. “As an ecosystem, we need to figure out a way to distribute light client trust roots in less than 21 day unbonding time to full nodes.” Expect more details from the Interchain GmbH team’s deep dive on the Tendermint 0.34 plan.Chain Upgrade ModuleThe initial versions of the Cosmos Hub used a flexible but painful chain halt to upgrade the blockchain. When we upgraded to cosmoshub-2 and cosmoshub-3, we stopped the Cosmos Hub for over an hour-a disruption we can’t afford as the Cosmos Network relies more and more upon the Cosmos Hub. This method of upgrade is challenging for validator operators and introduces an additional layer of risk for their operations, as well as to their delegators, who may be slashed. Thanks to the Regen Network team, this new upgrade module will automate the upgrade process to reduce the coordination complexity, potential for human error, and the demands on the validator operators to all upgrade at the same time.Stargate will enable the ability for a governance proposal to specify either an upgrade block height or time, safely shut down block production on the legacy chain, and then enable validators to opt into running the management process that seamlessly deploys the new software, migrates the state, and starts the new chain.The Regen Network has been running this upgrade process for nearly a year on their testnets and their validator community has already built up considerable experience with it. We’re anticipating a future of Cosmos Hub upgrades that are much less eventful, something we are all looking forward to.Next StepsBlock explorers, wallets, exchanges, we are asking you to schedule time in August for integration testing against the Stargate network.Validators, we are hoping that nearly all validators in the Cosmos Hub will participate in the Stargate testnet as a simulated upgrade. We are anticipating the first testnet to be July 27.Join us for the Stargate testnet to get used to this process. The Stargate team intends to run testnets and upgrades (using the Cosmos Hub genesis file) to broaden the pool of experience.Follow along on Twitter via @cosmos to ensure you don’t miss updates, and join our Discord #stargate channel to ask questions or to lend a hand, and join the Cosmos Stargate announcements channel!Get the word out on Twitter, translate and/or repost this article and others, or help us by syndicating it onto your own blog or channels.

A tale of Game of Zones: IR...

The IRISnet team’s story of hustle, dedication, and community.Often people would ask me, “why are you, out of the hundreds of blockchains in crypto, so particularly passionate about Cosmos Network?”While the reasons are countless, there are two main reasons that come to mind:First, the Cosmos ecosystem has always pioneered in the conception and implementation of cutting-edge ideas and technologies.The success of Game of Stakes, the first proof-of-stake adversarial testnet in the crypto space, quickly taught hundreds of new Cosmonauts how to use the tools available in the Cosmos ecosystem. This led to a successful and seamless launch of the Cosmos Hub in March of the same year.The success of Game of Stakes was fully recreated in Game of Zones, an incentivized testnet intended to test the limits of IBC and discover its strengths and weaknesses ahead of launching it into production. Cosmonauts from all over the world participated in the three-phase challenge, bringing results that few expected. brings us to the second point: the people involved.Let’s be honest, when this much prize is at stake, many would have done things at any cost to have an edge over their competitors. But in Game of Zones, 150 teams not only gave their best in terms of energy and commitment, but also in helping, collaborating, supporting, and celebrating each other to excel.This is Cosmos: an international ecosystem of some of the best-in-class operators of proof-of-stake blockchains that day after day made their knowledge available to all of us Cosmonauts.So whenever somebody asks me what I love about Cosmos network, I’m always ready to answer: the genius, the courage, and the humanity of those who are part of it.And amongst the many teams that participated, one particularly stood out to perfectly embody the Cosmos spirit. That team is IRISnet.Pre-Game of ZonesEven before the start of Game of Zones was announced, the IRISnet team spent time to thoroughly analyze the IBC module and the Relayer in order to prepare for the competition that would soon follow.In doing so, not only did the team discover an inaccuracy in the Relayer implementation, but also discovered three major bugs which were documented and submitted as useful material for the Game of Zones Bug Bounty.Here is a summary of the anomalies detected by the IRISnet team:Consensus bug This bug caused the loss of memory data after a Gaia daemon restart, causing a consensus failure. It should be noted that the bug was found near end of Phase 1a. To which the team alerted the organizers. This led to the decision to repeat Phase 1 (named Phase 1b) after the problem was finally solved. You can read more about this in Tess Rinearson|Interchain GmbH’s blogpost.ICS-20 Event bug When multiple messages were contained in a single transaction, the event data would be abnormal. Specifically, the events in subsequent messages would include those of the previous messages, leading to the data being excessively large and causing a number of problems such as the relayer not being able to pick up the proper data packet via query.Unordered channel bug ICS20 packets sent through an irregular channel can be retransmitted repeatedly, causing more tokens minted on the counterparty chain than are available on the source chain.In addition, although it was not required, the IRISnet team proposed a draft of an interchain incentive mechanism, which they considered extremely important for the development of the IBC ecosystem.Beyond discovering critical bugs that existed in the codebase, the team also provided the community with concrete tools to let the Cosmonauts experience what the future of Cosmos Network post-IBC has in store for them such as the IBC implementation of Rainbow Wallet and the GoZ State Visualizer.Well, we can say the boys didn’t sit on their hands!Phase 1aAfter carefully studying the competition rules set by Cosmos Devs, the IRISnet team has effectively developed automatic tools and monitoring procedures, mostly following these points:They started their own private transmission node instead of using a public one.The automatic program would then try again independently in case of a failed transaction.At the same time, the real-time monitoring system also included a series of alarms, so that devs could intervene manually and in a prompt manner in case of need.Despite the fact that in Phase 1a, as mentioned above, a consensus bug led to significant instability of the Game of Zones Hub, the team was able to effectively deal with the problems occurred.IRISnet ranked third in Phase 1a of Game of Zones, winning the Challenge Reward.Phase 1bWith the resolution of the Consensus Bug, Phase 1b of the GoZ seemed to start with the best of premises.It wasn’t long before the IRISnet team, driven by what happened in Phase 1a, decided to go even deeper into the ICS-20 Event Bug.This led to the core developers discovering an even more critical bug than the consensus failure bug that plagued Phase 1a. The bug was likely to be able to affect the results of the GoZ Hub. Going above and beyond, the team found other issues with memory overflow, node stop, and query timeout.This could have resulted in a malicious hacker to successfully conduct an attack on the various channels at any stage of the competition.After having pointed out to the organizers that the bug was still present on the Hub, IRISnet wanted to give a concrete demonstration of it using it for an attack on the public nodes after Phase 1b ended, effectively shutting down the Game of Zones hub.Confirming the excellent results maintained by the team during both Phases 1a and 1b, IRISnet won the GoZ Liveness Reward.Phase 2The main focus of the second phase of Game of Zones was throughput.Essentially, this meant that the team that was able to relay the most amount of packets with their relayer key on the GoZ Hub and the Game of Zones network wins this round.To achieve this, developers worked to improve and optimize the relayer, mostly focusing on the following aspects:Implement automated batch sending of cross-chain transactionsImplement automated batch relaying packetsImprove query efficiency by using multi-GoRoutine in relaying packetsAdd handling of exception such as timeout and transaction failureFix the issue that made impossible to get the proof of the packets created in the latest blockWhile the official ranking of Phase 2 has not yet been released, according to the unofficial P2P Validator Leaderboard, the IRISnet team ranked fourth out of a total of 150 teams.Phase 3The main objective for Phase 3 was to stress test the security model of IBC, and the winner will be the team that executed the best confusion or deception attacks against other zones.During this phase, the team implemented a deceptive relay between the GOZ Hub and Iris Hub and simulated a series of abnormal scenarios that illustrate the consequences and effects.A demonstration of the procedures carried out to achieve this result can be found here.The IRISnet team contributed substantially to the improvement of the Cosmos SDK and the Relayer by identifying key inconsistencies. They submitted two pull requests that address the issues (1 & 2)For phase three, as for phase two, the official ranking is not yet available, but I am pleased to announce that the IRISnet team has won the “Most Innovative/Deceptive State Machine” award!Really deserved, congratulations guys!The complete list of winners can be found in the replay of the Game of Zones Closing Ceremony hosted by Jessy Irwin, Jack Zampolin and Zaki Manian.Final considerations by the IRISnet teamTo bring this summary to a close, I wanted to conduct a small interview with the IRISnet team to see what this competition meant to them.Daniela: The team submitted constant code revisions, pull requests, updates of the Visualizer and even an IBC version of the Rainbow wallet. How did the team manage to simultaneously work on so many things during Game of Zones?IRISnet Devs: In order to work effectively in each of these fields you mentioned, our team was split into 3 teams (Adversarial competition, Rainbow-GoZ Wallet, and GoZ Network State Visualizer). Thanks to this, each of us has been able to focus on our work and put all of ourselves into the task without interruption and in a completely autonomous way.Daniela: Game of Zones, like the Game of Stake a year ago, is designed to test not only the code but also the teams participating in the competition. It seems obvious that this competition led to impressive technical improvements in a very short time, many creative use cases and incubated teams that are now familiar with using the IBC module and running the relayer.What are your thoughts on this? Which things did you find the most challenging and what was the most exciting thing about the competition?IRISnet Devs: Game of Zones is a global game that lasts for 3 weeks. Participants come from different time zones and there may be various temporary situations happening in this game, so it requires us to highly focus our attention, to keep thinking. It’s definitely a huge challenge.Because the amount of data and the load carried by each node of GoZ Hub is very large, ensuring that our program can run stably was a huge challenge.At the same time, in order to compete with various excellent teams, we needed to find ways to optimize our tools to obtain a better ranking. This was a very exciting challenge for us. If you want to see in-depth the tools we used during the competition, we have made open source our command-line tool!Daniela: All the work and time invested have only one ambitious final goal: the advent of IBC. What are your final thoughts about Game of Zones and what do you think is the next step forward?IRISnet Devs: Game of Zones was a very good opportunity to participate in learning to use the IBC protocol and the relayer. In the competition, we competed with many excellent teams. We saw many excellent strategies and ideas and learned a lot.We do hope Game of Zones will build a solid foundation for the establishment and improvement of the whole Cosmos ecosystem.ConclusionThanks to the IRISnet Team, who kindly summarized the key events, the history, and the work behind their participation in the Game of Zones.Despite being very reserved and humble about their achievements, I must acknowledge their willingness to put in the extra effort and strive for excellence even in situations that may be unexpected.Congratulations to IRISnet and all the teams who participated in the Game of Zones, bringing talent, innovation and squad spirit!In this competition the real victory, the one given by the commitment to a common goal, belongs to all of us!

Announcing the Cross-Chain ...

The Cross-Chain Hackathon, hosted by Gitcoin, started as a way to involve developers from around the world and give them ample time to work on their projects. After months of planning and almost one month of hacking, we’re excited to say we received over 20 total submissions! Let’s go over the winners.Cosmos Challenge Winners ($15,000 total in ATOMs)With the Cosmos challenge, we wanted to see what developers can build with the Cosmos toolkit. This includes the Cosmos SDK, IBC, Ethermint, Peggy, and CosmWasm. Here are the winners:1st place — MeiChain ($6000 in ATOMs)MeiChain is the MEI stablecoin system with a collateral debt position (CDP). There’s three blockchains working together. The Cosmos Hub users hold their ATOMs and use them as collateral for minting MEI. Next, Meichain is used to store the CDP and the MEI token itself. Lastly there’s Bandchain, which serves the ATOM/USD price feed from several exchanges to Meichain. All chains communicate to MeiChain by sending packets across the chain using IBC relayers. (view Github)2nd place — LikeCoin ISCN ($5000 in ATOMs)LikeCoin is a public blockchain for content monetization, attribution, and distribution. For this hackathon, they provided two components. 1) A Cosmos SDK module for users to record content metadata according to the ISCN specification and 2) IPFS plugins for querying and parsing this content metadata from the chain. (view Github)3rd place — Qonico ($4000 in ATOMs)Qonico is a Cosmos blockchain implementation for small IOT devices. It includes a guide, a cross-chain client using RaspberryPi, a web client and a js client. (view Github)Agoric WinnersAgoric’s winners made good use of its platform for building reusable smart contracts. They were:Grand Prize ($1000 in ATOMs)KryhaDapp — addressed the problem of plastics recyclers not knowing what kind of plastic was used to make bottles and if it was recyclable. Their solution provides a single shared source of truth for tracking product lifecycles. To do this, they used multiple reusable and cooperating contracts (five in all), with a useful UI. (View Github)Winners ($500 each in ATOMs)Time Release — a contract that transfers funds, but only after a specified amount of time has passed. It was notable for being a useful and interesting reusable component with test automation. (View Github)Bonsai Exchange — a fun sales application where users buy bonsais and plant them. It reused an existing component, wired it into a new UI, and interacted with Agoric’s wallet implementation. (View Github)Honorable Mention ($250 each in ATOMs)Goodwill — a merger of a modified Agoric encouragement dapp with the ultimatum game, a standard economics experiment to measure trust. One person makes an offer on how to divide assets, and another accepts or rejects. Acceptance means the assets are divided per the offer, rejection means both parties get nothing. This project was a start at making re-usable components for quickly building experiments. (View Github)Ice Cave — while incomplete, it made good progress towards integrating Agoric smart contracts with the Phaser gaming framework. The result is a decentralized game with non-fungible loot boxes on top of the Agoric blockchain. (View Github)Band Protocol WinnersSeveral teams provided submissions for Band’s DeFi category for the Cross-Chain Hackathon. Here are the winners:Winners (2000 BAND each)MeiChain — The MEI stablecoin system with a collateral debt position (CDP). Uses the Cosmos Hub, MeiChain, and Band’s price oracles. (View Github)CoinPriceBet — A prediction market built on the Cosmos SDK which has a frontend demo and sources crypto prices from Band’s oracles using IBC. (View Github)Honorable Mentions (500 BAND each)StakeSafe — an interface for staking any supported liquidity pools safely, with pool information coming from Band’s price oracles. (View Github)SEMA — allows users to buy second-hand items with the ATOM token by posting items, accepting the transaction, sending tokens, and exchanging tokens. (View Github)Notable TeamsFor the Cosmos challenge, several exceptional teams that provided submissions that we didn’t cover above. Each of these teams is eligible for a Cosmos T-shirt. These include:Map of Zones — a visualizer that displays a galaxy of the interconnected networks built on the Cosmos SDK with the IBC module. (View Github)AstroCanvas — a game and radical experimentation in stake decentralization. Inspired by the 2017 Reddit April Fools project r/Place, AstroCanvas takes this one step further and applies it to solving staking centralization of proof-of-stake blockchains. Delegators are given specific colorToken that represents the right to change one pixel in the canvas when they delegate their staking token to a Hub validator. The catch? Not all colorToken are the same. Delegators can earn colorToken of a specific color (white, black, red, etc) depending on the voting power of the delegated validator. So for example, validator with #1 to #10 rank in voting power gives delegators colorTokenWhite which only allows you to place a white pixel on the canvas. If you want to place a blue pixel, you need colorTokenBlue which you may only receive when you delegate to a validator with voting power ranging from #80 to #90. (View Github)OpenMarket — provides a decentralized marketplace for non-fungible tokens (NFT) trading over IBC. It’s part of the Сosmos ecosystem and can be used to trade the non-fungible asset of any blockchain in it. This is done using the IBC protocol which, among other things, allows cryptocurrency and NFTs to be transferred between blockchains. (View Github)Real Estate Exchange — a real estate trade application built on Cosmos SDK. Users have tokens and they can exchange real estate as securities. Each issuer pays dividends as another blockchain’s token to the security owners. The trade is empowered by the Cross framework, which supports a cross-chain atomic swap between blockchains connected via IBC. (View Github)CoinPriceBet — A prediction market built on the Cosmos SDK which has a frontend demo and sources crypto prices from Band’s oracles using IBC. (View Github)SEMA — allows users to buy second-hand items with the ATOM token by posting items, accepting the transaction, sending tokens, and exchanging tokens. (View Github)Cross Chain Crawler — uses Web of Trust and Google NL APIs to rate as many sites and services on various blockchains. (View Github)ConclusionThank you to everyone from Gitcoin, Agoric, Band, Interchain GmbH, Tendermint Inc, and the Interchain Foundation for helping to make this virtual hackathon a reality. We’ll be reaching out to the winners of the Cross-Chain Hackathon soon regarding KYC and tax documents along with those eligble for t-shirts.

Technical Game of Zones Upd...

There are several goals of Game of Zones: to educate the public about IBC; to stress test the system in an adversarial and competitive setting; and to shine a light on any potential vulnerabilities in the IBC protocol and implementation. Earlier this week, participants in Game of Zones successfully helped us identify a problem. It wasn’t exactly a bug in IBC, but it was a problem nonetheless. We’re excited to fix it.I’ll share more on that in a moment, but first, some context:On Monday, the Iqlusion team, which sometimes also goes by “Cosmos Devs,” posted an update to the Game of Zones challenge. In short, the timeline has been adjusted to accommodate the aforementioned problem, which popped up at the end of Phase 1. (For more details on Game of Zones logistics, please see Iqlusion’s post.)Today, I’m following up on that issue on behalf of the Interchain GmbH team, which includes the core development team for IBC. (We’re helping Iqlusion out as they administer Game of Zones.) I’ll share a deeper analysis of the bug and root cause, as well as the cross-entity next steps that we’ll be taking together, to ensure a smooth conclusion to Game of Zones, and, more importantly, a robust Cosmos Network.The BugAt the conclusion of Phase 1 of Game of Zones, participants were asked to upgrade their software to a new commit of Gaia and the Cosmos SDK, and restart their nodes. After doing so, a number of participants reported that their chains were halting, and other participants reported seeing “invalid port” errors.The Berlin-based Interchain GmbH team started investigating on Monday morning CEST, and was able to identify the problem that afternoon and merge a patch. The team then worked with community members to verify the fix across several nodes. That night, the Iqlusion team updated the Game of Zones timeline.Root CauseThe bug came from the way that the capabilities module was being initialized inside Gaia. It was erroneously being initialized with a cached context, which meant that the changes made during application initialization were not correctly persisted to the store.We were able to identify this problem quickly, because it was, in fact, a known bug. It had actually been fixed in a patch for the Cosmos SDK, a week beforehand!So how did this bug persist in Gaia, even after it was identified and patched in the Cosmos SDK?Root-er CauseWe were able to pinpoint the buggy code, but we’ve also been able to find the bigger problem: As core development teams have decentralized across the Cosmos ecosystem, responsibility for maintaining Gaia hasn’t been clear. Although Gaia plays a key role as the daemon that runs the Cosmos Hub, it has a different software lifecycle from the Cosmos SDK and Tendermint Core. More concretely: Gaia is not updated as frequently, and changes to its dependencies may not get incorporated immediately.In this case, this mismatch created trouble.Next StepsIn the immediate term, Iqlusion will be responsible for porting SDK updates to Gaia. This arrangement will ensure that key fixes will be applied to Gaia, and that Gaia will be proactively maintained moving forward; not just during Game of Zones, but beyond, too. The Interchain GmbH team will help out here, too, by reviewing all Gaia releases and providing a second pair of eyes on this very important piece of software.The Interchain GmbH team will also start helping out with relayer development, testing, and support during Game of Zones. The truth is that Game of Zones has ended up being much more popular than any of us expected! Our hands-on community is overwhelmingly a blessing, but y’all have made Game of Zones a bigger project than what one team can handle alone.As I wrote in the beginning of this post: Game of Zones is an opportunity to unearth vulnerabilities in the IBC protocol and software; today we also found a gap in our ecosystem-wide organizational coverage and communication. And we’re patching these things, just as we’d patch our code. These changes will eventually help us continue Game of Zones in a robust and intentional manner, and it will ultimately help us launch IBC in a secure and stable way on the Cosmos Hub.The Interchain GmbH team wants to thank everyone for their ongoing participation, and especially for their feedback, during this process. We’re looking forward to the next phase — not only of Game of Zones, but of the Cosmos Ecosystem. Thanks for working with us to make it as ✨celestial✨ as possible.Technical Game of Zones Update from Interchain GmbH was originally published in Cosmos Blog on Medium, where people are continuing the conversation by highlighting and responding to this story.

IRISnet Enterprise IRITA ha...

China’s Blockchain-based Service Network BSN officially kicked off in Beijing on April 25, 2020. The BSN initiative, a joint effort led by the State Information Center of China, China Mobile, China UnionPay, and Red Date Technology, is a standardized, nationwide public infrastructure network across different regions and business sectors to support faster and cheaper blockchain development and deployment. The announcement of the BSN launch saw coverage from the top media outlets within the country including People’s Daily Online, Sina Finance, and Tencent News. , the President of People’s Daily Online, outlined at the conference that BSN is emblematic of leveraging blockchain technology to conduct national strategies, address key issues, and create real value. The launch of BSN also captured widespread attention from overseas. Coindesk, for example, has provided consistent media coverage on the development of BSN since its initiation, most notably an in-depth interview with Yifan He, CEO of Red Date Technology. Red Date Technology is one of the founding members of BSN, responsible for architecting and operating the infrastructure. Mr. He briefly touched on the vision of BSN in the said interview: “One of our primary goals is to include as many blockchain frameworks as possible and make them accessible under one uniform standard on the BSN platform. In that way, we can save users’ overhead costs to build a blockchain while being able to offer more custom services.” A partnership between BSN and Cosmos was also mentioned by He. The partnership will be through IRITA, an enterprise-focused solution branching off of the Shanghai-based IRISnet project.How Does IRITA Support BSN?BSN introduces three network participant roles: 1)Cloud service providers; 2)Blockchain framework providers (particularly Consortium Blockchain); 3)Application developers. IRITA falls into the second category and the Shanghai based IRISnet dev team Bianjie has closely followed BSN’s design to get IRITA on board. The end goal is to provide the application developers to be able to build applications using IRITA on BSN.Since the beginning of 2020, Bianjie has been actively collaborating with Red Date Technology to adapt IRITA aligns with BSN’s adaptation standards. A prime example would be the encryption module Bianjie developed according to the specifications of China’s National Encryption Algorithm. Following a plug-and-play design approach, IRITA offers native support for different cryptographic algorithms according to customers’ specific needs, and the version of IRITA on BSN will use China’s National Encryption Algorithm. In January this year, Bianjie submitted various technical documentation on developing and deploying IRITA to the staff at BSN with the intention to help developers easily and quickly deploy their own IRITA runtime. We look forward to supporting more and more developers building on IRITA and grateful for the amazing feedback we have received from BSN so far. Currently, BSN supports top consortium blockchain frameworks including Hyperledger Fabric by IBM and FISCO BCOS by Tencent WeBank. It is our goal to see IRITA join the prestigious group and collaborate with other players in the space on driving the world towards a better future.What Value Does IRITA Bring to BSN?Powered by Tendermint and the IRIS SDK, IRITA (Inter-Realm Industry Trust Alliance)is the first enterprise-focused consortium blockchain coming out of the Cosmos ecosystem. Leveraging their extensive experience in providing technology solutions, Bianjie was able to deliver a slew of exciting features in IRITA including 1) privacy-preserving data sharing; 2) high-performance consensus engine; 3) advanced inter-chain communication; 4) highly practical on/off-chain interoperability; 5) and flexible digital asset modeling/exchange. IRITA carries the potential of being widely applied in finance, health care, supply chain, and other applicable business scenarios. Inspired by the Inter-Blockchain Communication IBC protocol by Cosmos, IRITA takes it one step further with its innovative service layer (a.k.a IRIS Services) in connecting blockchains with conventional enterprise applications, supporting data exchange between heterogeneous computing systems (e.g. public chains, consortium chains, and legacy systems). Particularly in the case of information exchange between public chains and consortium chains, IRITA in conjunction with the IRISnet service hub brings extraordinary value to the existing ecosystem and the future that has yet to come. The Bianjie team recently open-sourced implementation of integrating Chainlink as a trusted oracle into iService. The synergy between IRISnet and Chainlink has been a long time coming. During the BSN interview with Coindesk, Mr. He also mentioned besides Cosmos that BSN would also like to support Chainlink for oracle service, and we can expect IRITA and IRISnet to provide a very convenient integration path when bridging the Chainlink’s services for consortium blockchain applications on BSN.About Cosmos & IRISnetCosmos is one of the most prominent blockchain projects focused on inter-chain communication. Founded in 2016 by the core team behind Tendermint, the Cosmos project aims to bring inter-chain communication to an ecosystem of independent parallel blockchains. IRISnet (a.k.a IRIS Hub) is the world’s first self-evolving, BPoS (Bonded Proof-of-Stake) blockchain designed to be the foundation for next-generation distributed applications. Built with the Cosmos-SDK, the IRIS Hub enables cross-chain interoperability through a unified service model, while providing a variety of modules to support DeFi applications. IRITA is an enterprise blockchain product from the IRISnet development team.About ChainlinkChainlink is a decentralized oracle network that enables smart contracts to securely access off-chain data feeds, web APIs, and traditional bank payments.Resources developer-competition-award-of-china-blockchain-449a6cee8391 Enterprise IRITA has been chosen by BSN to support Cosmos Ecosystem was originally published in Cosmos Blog on Medium, where people are continuing the conversation by highlighting and responding to this story.

Cosmos Network is Coming to...

In light of recent events, while people are distancing themselves physically, the need for social connection has never been more pronounced. Despite capital markets and crypto markets alike having more than halved in value across the board on any given asset, we’ve been compelled to work smarter and more creatively than ever.Using creative treasury management, we’ve already started several ecosystem-bolstering initiatives aimed directly at supporting Cosmos Network’s most prolific contributors. Recent initiatives that were publicly announced were that of the Community Contributor Grants program and the Tendermint Inc ATOM Rebonding.Other ways we are continuing to grow the Cosmos community is by rolling out a series of online events in order to get you access to the same quality of workshops and content you’ve been accustomed to when you hear the name ‘Cosmos’. The first such online event will be launched in May.As May approaches, this not only means springtime, warmer weather, and hope, but in the cryptoverse, it means New York Blockchain Week. And with NYBW comes the annual CoinDesk Consensus:Distributed conference, the biggest token holder conference of the year that attracts crypto enthusiasts from over the world. Cosmos has been a mainstay at Consensus. In fact, it was in New York, this time two years ago, where one of the most memorable moments and viral memes in the history of the Cosmos-Ethereum friendship was birthed.🔔 👏 Do the words “Vitalik clapping” ring a bell? 👏 🔔If you’re bored and staying at home, you can watch the full-length boat party video here 👇 year, with no boat 😿 and no physical conference, the show must go on. We’re hosting an hour to hour and a half long video conference event at Consensus:Distributed this year in its “Foundations” segment on May 12th, the second day of the online conference.If you aren’t registered, you can register here, entirely for free, which is a steal compared to past conferences: Cosmos portion of the conference will have a (tentative) agenda broken down below over a 1–1.5 hour long period:If you haven’t registered, do it here 👇Website: Link: you there, Cosmonauts!The relentless pursuit to an Internet of Blockchains can not be contained by a pandemic.
