Cosmos reached a major milestone in April 2021 when it launched the Inter-Blockchain Communication protocol, the Cosmos standard for interoperability. IBC allows independent blockchains to connect, transact and exchange tokens. This protocol makes it possible for them to scale up and thrive in an interconnected network. We have seen the rise of a new economy in just eight months. 25 chains have joined the #IBCGang, and many more are in the pipeline!
IBC is a key factor in the rapid growth of the Internet of Blockchains. We’ve witnessed a huge 5.8 million IBC transactions to date and significant traction among CosmosDeFi applications. Osmosis and Sifchain are just a few of the decentralized exchanges (DEXs) that are expanding quickly. They make previously difficult-to-find tokens easily available, and allow transfers, swaps and pooling IBC tokens among other activities.
Osmosis is an excellent example. Since its June launch, the Cosmos DEX has seen a tremendous rise in liquidity. It started at $49 million, and reached an all-time high in December at $730 million. Daily trading volumes have exceeded $85 million. OSMO/ATOM is most used liquidity pool, followed closely by OSMO/UST (LUNA/UST) and OSMO/UST.
Applications and protocols that are successful with IBC, draw more users to Cosmos, benefit the whole ecosystem. This makes DeFi on Cosmos more enjoyable, rewarding, and satisfying for everyone. Cosmos is a major contender in this sector, with its low transaction fees and high liquidity (the average trade size for Curve Finance is $500,000 to $1,000,000), DeFi on Ethereum being reserved only for whale traders.
Emeris, the portal to all crypto apps, no matter what blockchain they are built on, will take the user experience to the next level from its public launch. Already integrated with the Gravity DEX protocol, Emeris will offer users a browser extension wallet, a super-intuitive way of managing tokens cross-chain, and integration with many other protocols and DEXs.
And there’s plenty more to come. IBC doesn’t stop at Cosmos-built blockchains. Coming up in 2022, we’ll be connecting to many other major ecosystems including Bitcoin, Ethereum, Polkadot, and Celo, unlocking vast amounts of liquidity that will flow through the Internet of Blockchains. Read on to find out more about this journey and the next steps on our path.
The 25 chains that have enabled IBC and interconnected to join the #IBCGang already have a combined market cap of more than $60 billion. Assets that are available for users to trade include ATOM, USDT, OSMO, LUNA, CRO, SCRT, and many others. Let’s meet the #IBCGang chains below.
Since we began our first transaction between Cosmos Hub and IRISnet in April, we are now frequently registering more than 1.7 million IBC transfers in a 30 day period. Below, you can see graphical representations of IBC transactions, from quantity by chain to IBC transfers by zone. And did we mention, more Cosmos chains are coming fast?
Coming soon to the #IBCGang will be another score of Cosmos chains each bringing unique features, use cases, and value to the Internet of Blockchains:
We’re thrilled to see the Cosmos economy growing, but our vision for the sustainable development of blockchain technology is far more inclusive than that. Enabling blockchain interoperability is not only about the Cosmos network. Multiple solutions are in the works right now that will allow us to connect to other major blockchain ecosystems. Let’s take a look at all the solutions using IBC to make it happen.
The Nomic Bitcoin bridge creates an NBTC token that is redeemable for BTC, which can be sent over IBC and used throughout Cosmos. This bridge makes use of Bitcoin’s new Taproot feature and provides strong safety guarantees, as, with some Bitcoin bridges, validators have the power to mint BTC tokens without them actually being deposited on the Bitcoin mainnet. With Nomic, this attack won’t work unless the validators also have a majority of the Bitcoin hash power.
There is also a security feature that returns everyone’s Bitcoin on mainnet if the network has an extended liveness failure. Nomic’s design further ensures that malicious validators lose their stake even if they have 2/3+ of the voting power (and therefore are able to censor transactions). It also uniquely creates an opportunity for validators to earn BTC rewards, providing an additional incentive to use it. Nomic is working hard on rolling out this groundbreaking solution and we’ll get our first taste of it in the coming months (more details on this soon!).
The Axelar Network is a decentralized network enabling cross-chain interoperability between all blockchain ecosystems. The suite of protocols supported by the Axelar network, including IBC, supports integrations with Cosmos, Ethereum, Polkadot, Avalanche, Fantom, and other chains. Its building blocks can be used by developers to deploy connections to other blockchains and develop custom protocols quickly.
Axelar’s primary goal is to make it easy for developers to build their dApps on the blockchain platform best suited for their needs without sacrificing access to applications, assets, or users on other chains. To achieve this, Axelar is building a developer toolkit of protocols and APIs that run on top of their decentralized network of validators, which secure the network. This general-purpose toolkit enables developers to seamlessly build and deploy their dApps, while connecting their users to every blockchain participating in the Axelar network.
Axelar is currently in a testnet mode with dozens of validators and hundreds of ecosystem participants building around the stack. Axelar also recently launched an incentivized community program and community academy.
Very soon Cosmos will be connecting to Polkadot! There are several key teams working on robust IBC solutions that will allow the two giant ecosystems to interoperate. The support for integrating IBC into Substrate is already in active development, with teams from core Cosmos contributor Informal Systems working on major codebase refactoring such as Rust no_std support in ibc-rs (the repo that contains IBC module support in Rust).
Octopus Network has been working hard as well at implementing IBC support for Substrate (substrate-ibc), and there have been some advances in the relayer logic in order to enable one-day transfers from a Cosmos chain to a Substrate chain. The Composable Finance team also has a number of efforts in progress to make this integration a reality, including working on an IBC light client for BEEFY, the substrate-based bridging solution for Kusama, to non-substrate based chains.
This light client would be merged into the canonical IBC-go repo and would be available for all Cosmos chains to communicate with Kusama and Polkadot. In addition to this, Composable is working with Strangelove Ventures to add support for substrate-based chains to ibc-relayer-go, and the Parity Bridges team to get BEEFY live on Kusama.
In coordination with the Interchain Foundation (ICF), the Celo Foundation awarded a grant to Chorus One to construct a bridge between the Cosmos Hub and Celo, making use of IBC technology. The bridge will expand interoperability between the Cosmos and Celo ecosystems, allowing users, funds, and value to flow more freely — another important step toward achieving a globally inclusive alternative financial system.
The Proof of Concept for the integration has already been approved, the functionality is working, and the development teams are now testing the full integration with the relayers and end-to-end tests. Watch this space in the coming year!
Datachain has been working on various solutions developing blockchain interoperability for enterprises, releasing an IBC module in Solidity that enables interoperability between different EVM-compatible blockchains, starting with Hyperledger Besu. This solution will allow for tokens, NFTs, and local currency built with Hyperledger Besu to communicate with different blockchains, such as Hyperledger Fabric.
Interconnectivity between enterprise chains with IBC is a major step to onboarding global enterprises, helping them scale to meet the needs of their users, and grow for mass adoption of their applications.
Datachain also recently submitted a proposal that was unanimously approved to the Harmony blockchain community to build a bridge between Cosmos and Harmony. Harmony’s mainnet runs Ethereum applications with 2-second transaction finality and 1000 times lower fees, as well as secure bridges to Ethereum and other chains.
To develop this IBC-enabled bridge, Datachain will develop token transfer using ICS-20. The HRC-20 token on Harmony will be handled as ICS-20 on Tendermint based ledgers. The estimated timeframe for completion is three-four months, so taking Cosmos interoperability to a whole new level.
No concrete projects are yet in the works for a bridge to Avalanche, however, founder Emin Gün Sirer revealed that connecting to Cosmos through IBC was “something I’ve thought quite a bit about,” and said that “we could have Cosmos to Avalanche bridges in a very seamless manner.” We’ll be keeping a close eye on developments with this up-and-coming blockchain ecosystem!
Thanks to proposal 56 which was unanimously voted in, an IBC router will soon be added to the Cosmos Hub. This is a fundamental step in the continued growth and efficiency of the Internet of Blockchains. The Hub will become the Interchain Router, meaning that new zones joining the #IBCGang no longer need to maintain a large amount of infrastructure, such as archive nodes and relayers for each counterparty chain, to connect with the growing number of chains in the ecosystem.
A new feature will be added to IBC on the Hub that enables packet routing for ICS20 transfers. Strangelove Ventures has delivered an IBC Middleware module that will allow the Hub to play the role of IBC Router. This marks the beginning of a new era of the Hub offering critical interchain services to other chains and, at the same time, allowing validators and stakers to benefit from these relationships.
With 25 chains already connected and the Cosmos Hub at the center providing vital interchain services, IBC is starting to reach its goals. Connecting to Bitcoin, Polkadot, Celo, Harmony, and other flourishing ecosystems will also greatly increase the utility and scope of Cosmos DeFi, unlock deep liquidity that will flow into the Cosmos ecosystem, and help grow the DeFi sector at large.
Through IBC, we can improve inter-blockchain collaboration, and provide a much-enhanced user experience, from more intuitive interfaces and lower fees to a simpler way of managing their cross-chain assets. In 2021, IBC was launched, in 2022, we’re going to see what happens when it reaches its full potential.
