Cosmos Network: Interchain’s Request for Proposals — Expanding Environments, “Epicenter Live” and Interchain Conversations conference sessions, Introduction to Ansible with Greg Szabo, Ecosystem updates

Biweekly update 10th June — 24th June

Welcome to our first biweekly update on Cosmos Network!

Over a period of two weeks, the team was extremely active! Interchain Foundation’s Greg Szabo provided an introduction and overview of Ansible on the weekly Tendermint developer sessions. At the inaugural Cosmos conference in Berlin the team featured in two bonus Epicenter episodes. EP 1 talks about blockchain interoperability and features Jae Kwon. EP 2 tackles the issue of validators and governance in Cosmos. Such an engrossing listening! Worth to mention, the conference brought together over 200 people in the Cosmos community including many developers, validators and members of the Tendermint team! The conference was followed a two-day hackathon over the weekend, which was a lot of fun! As for upcoming events, HackAtom in Seoul and GopherCon in San Diego coming in July. Zaki Manian, Tendermint team’s head of research, will be presenting on the latest developments in multichain networks and Cosmos IBC during Web3 Summit 2019 in Berlin in August. These weeks the ICF ran a general-purpose funding program for projects that advance its mission of open, decentralized networks. Currently, the ICF is particularly interested in projects that expand the security and capabilities of the Cosmos ecosystem to more environments, including networks, languages, protocols, devices, browsers, etc. As such, the ICF is issuing a Request for Proposals to focus the funding on projects most critical to the development of the Cosmos ecosystem - including PoS improvements, Interchain infrastructure, ABCI frameworks and integrations, secure signers. The community constantly grows. There are a lot of projects building on the Cosmos ecosystem. It is impressive and continues to flourish! Developers have been working extremely hard over the period of the last two weeks so many updates on the projects appeared in the media landscape. IRIS released Rainbow V2.0 with Cosmos (ATOM) support. Kava blockchain was introduced - the first cross-blockchain DeFi platform enabling traders to leverage and hedge using a multi-collateral CDP system and collateral-backed stablecoin. Lunie announced three important libraries — Cosmos-API, Cosmos-Keys, and Cosmos-Ledger. Swishlabs and THORChain have shipped a one-way Ethereum bridge as part of their work with Interchain on Cosmos technology. The first BTC-pegged token released on a Cosmos SDK: BTCB. Lastly, these weeks team members wrote a lot on Libra. aLSO, Alex Skidanov tweeted on differences between Tendermint team and Libra approaches to consensus. More to follow. Stay tuned for Cosmos Network updates in the coming weeks!

Tendermint DEV session: Introduction to Ansible | Greg Szabo:

Interchain Foundation’s Greg Szabo provides an introduction and overview of Ansible on the weekly Tendermint developer sessions.


Request for Proposals — 2019 — Expanding Environments

by Interchain Foundation.

RFP-2019–EE-1: Proof-of-Stake Improvements

Blockchains in the Cosmos Network are secured via Bonded Proof-of-Stake mechanisms that incentivize co-ordination between validators and token holders and provide security guarantees to light clients and to other blockchains. The current mechanism on the Cosmos Hub is arguably the most advanced Proof-of-Stake implementation in the world, but there are many dimensions along which it can be improved. These include monetary policy, delegator and decentralization incentives, validator slashing risk, fee distribution, key management, interchain security, and much more. Of particular interest are ideas for “cross-chain collateralization”, where Proof of Stake deposits on one blockchain can be used, via IBC, to secure execution on many other blockchains. The ICF is looking for concrete descriptions of problems, as well as proposals and implementations for solutions.

Apply To:

  • Research, analyze, and document the design space and tradeoffs in Cosmos-style Bonded Proof of Stake mechanisms
  • Write a detailed specification, analysis, and/or simulations for a particular design
  • Implement a particular design using the Cosmos-SDK

RFP-2019–EE-2: Interchain Infrastructure (IBC, Pegs, Oracles, etc.)

At the heart of the Cosmos Network is the idea that digital rights can be securely transferred between distinct decentralized administrative domains like blockchains. In other words, groups of validators on one chain can hold and transfers assets on other chains. IBC is a formalization of this idea for so-called “Cosmos native” blockchains.

The ICF is interested in projects that expand the number and type of blockchains able to participate in this common distributed custodial infrastructure in general. This includes projects to enhance IBC or implement it in other languages, but also projects that support communication with non-Cosmos-native blockchain networks, like Bitcoin, Ethereum, Polkadot, Tezos, Zcash, Monero, and many more. Such constructions include “Pegs”, which peg value on one chain to control by another, but also “Oracles”, which provide more generic data feeds between chains. The ICF is interested in exploring many different peg and oracle designs on the many different platforms, and even on the same platform, and on implementing such designs as modules within the Cosmos-SDK and other ABCI frameworks. They’re also interested in the relationship between these designs and IBC.

Apply To:

  • Research, analyze, and document the design space and tradeoffs of peg, oracle, and other “bridging” designs
  • Write a detailed specification for a particular design
  • Implement a particular design
  • Implement modules in the Cosmos-SDK or other framework that support a particular design (eg. a module to detect Byzantine behaviour on another chain)

Example projects include:

RFP-2019–EE-3: ABCI Frameworks and State Machine Integrations

One of the key features of Tendermint Core is the ability to securely replicate arbitrary deterministic state machines in any language via ABCI. This applies not just to newly developed state machines, written with Tendermint in mind, but also to those written independent of Tendermint, or even despite it! We’re interested in seeing many more of the world’s state machines being integrated with ABCI, enabling them to run on Tendermint, including state machines for cryptocurrencies, like Bitcoin, Ethereum, Tezos, and Zcash; those for service-discovery, like etcd and Consul; those for arbitrary computation, like WASM; and those for various other interesting distributed applications (gaming, governance, etc.).

However, ABCI is a quite low-level protocol (say, like HTTP), and applications should actually be written using higher-level ABCI application frameworks (say, like Ruby on Rails). Integrations with existing state machines should use existing frameworks, or should proceed alongside development of new frameworks. The ICF is looking to expand the number of languages for which such frameworks exist, to ensure many state machines in that language can be easily integrated with ABCI. They’re also looking to expand the capabilities of existing frameworks, for instance by improving core functionality or adding new general-purpose modules. The ultimate goal is to enable application developers in any language to leverage the power of large-scale Byzantine Fault Tolerance.

Apply To:

  • Implement or improve an ABCI server in a particular language
  • Implement an ABCI framework for building applications in any language with an ABCI server
  • Improve an existing ABCI framework by adding or improving features or modules
  • Integrate an existing state machine environment into ABCI using a framework so it can run as a Tendermint application

Example projects include:

RFP-2019-EE-4: Signing on Mobile, Browsers, and HSMs

At the heart of every Cosmos blockchain are validators signing votes and users signing transactions. Signing is a critical, highly sensitive operation and is the foundation of all security in the system. They’re interested in extending the number of environments capable of securely signing messages in the Cosmos ecosystem. For validators, this means HSMs, almost exclusively. For users, it means mobile devices, browser extensions, native applications, HSMs, and even command line clients in other languages.

Apply To:

  • Implement a secure signing application

Example projects include:

  • Ledger Cosmos App
  • Lunie Chrome Extension

“Epicenter Live” and Interchain Conversations conference sessions

Two bonus episodes which features content from the recent Cosmos conference in Berlin.

Last week, Brian, Sunny, Meher, and Sebastien attended the Interchain Conversations conference in Berlin. As the inaugural Cosmos conference, it brought together over 200 people in the Cosmos community including many developers, validators and members of the Tendermint team. The conference was followed why a two-day hackathon (or HackAtom) over the weekend, which was a lot of fun!

This week, they’re bringing you two bonus episodes recorded from the Interchain Conversations conference!

Episode 1 — Epicenter Live and a Conversation with Jae Kwon

The number for the circulating supply for ATOMs / @cosmos on @CoinMarketCap is totally wrong. I thought they’d have fixed this by now, but anyway. Here is a thread for what the correct number should be:

The only ATOMs that were not fully liquid at launch were those owned by @tendermint_team. This amounted to 23,619,895. So at launch the “circulating supply” was 236'198'958*0.9 = 212'579'062.

The @Libra_ release looks really amazing. Based on HotStuff (which is itself inspired by Tendermint!), written in Rust, with a new smart contract environment, open source license, and non-profit governance. All fantastic things. But the social implications are terrifying to me.

A short thread on HotStuff vs Tendermint for Libra.

Reddit discussions:

Let us make ATOM more popular than EOS! Leave a Like for ATOM and make ATOM the #1 cryptocurrency.

Earned my first full Atom via staking…. It’s not much (yet), but it’s (hopefully) honest work.
