ALT The Inter-Blockchain Communication Protocol 2023 year in review.
Reminder: Interoperability is a public good.
The core IBC protocol never extracts value. No in-protocol rent extraction or hidden fees.
The code is open-source, free to use, and rigorously peer reviewed by world-class developers.
All blockchains deserve to communicate.
ALT Image from MapofZones.com showing 80 out of 107 IBC-enabled chains.
The Inter-Blockchain Communication Protocol #IBC is a blockchain interoperability solution that secures $30B+ in annual asset transfers for 100+ chains.
But it can be tough to understand how IBC works.
@ibcprotocol aims to explain IBC for developers and researchers.
ALT The logo for the Inter-Blockchain Communication Protocol on a blue background.
💥 Welcome @Cardano to the interchain.
The Cardano Foundation @Cardano_CF is developing a custom IBC implementation to connect Cardano to the IBC network of 110+ chains.
IBC is now connected to @solana, brought to production by the team at @Picasso_Network and @ComposableFDN.
They built a custom IBC solution that overcomes Solana's lack of native state proofs without requiring changes to its native architecture.
IBC is evolving.
The TLDR:
1. 10x simpler
2. 100x faster and easier to implement in smart contracts
3. Still powerful, permissionless, and neutral
Here's what's coming in IBC v2 🧵👇
8000+ NFTs have been IBC transferred in 2024, powered by ICS-721, the NFT transfer module, and its Cosmwasm implementation cw-ics721.
A technical walkthrough of the module and its development story, a collaborative effort between @stargazezone@irisnetwork@arkprotocol 🧵
ALT ICS-721 is a code module that enables cross-chain NFT transfers over IBC. Its CosmWasm implementation is cw-ics721.
Hello world.

The first ever Hub IBC transaction to Ethereum testnet!
After many years of waiting, IBC is now connecting to every ecosystem.
Dymension connects RollApps with IBC via a single IBC connection to the @Dymension Hub. Try it: portal.dymension.xyz
Plus, they are developing eIBC middleware to enable token transfer for optimistic rollups without waiting the dispute period.

IBC has been enabled on @Optimism for the first time ⚛️
The first IBC transfer between OP-Sepolia and Ethereum Sepolia has been completed.
It's a new implementation built by @tokifinance & @datachain_en, aiming to unlock IBC for OP Stack chains🧵
March 29, 2021: Cosmos Hub enables IBC.
March 29, 2024: IBC has the largest network of interconnected chains in the world.
On April 2, a special episode of #InterchainJam with @cosmos@ibcprotocol and iconic teams from across the interchain.
$1.03b in transfers and 2.3m monthly active accounts: 30d IBC Network Stats from July - August. 🔥
Let's explore the @mapofzones 👇
This month, 118 chains were actively connected through IBC and processed $1.03b in transaction volume.
@osmosiszone drove the highest IBC volume among all connected chains.
Osmosis and @cosmoshub were the chain pair with the highest number of IBC transfers.
@celestiaorg - @Neutron_org were the highest volume chain pair, processing the largest total value transferred via IBC.
2.3m monthly active accounts initiated IBC transfers across the entire network. ⬅️➡️
These metrics underscore the @cosmos interchain's growing adoption. Looking forward to the continued expansion of the interchain.
🎉 New Release: ibc-rs v0.52.0
Includes useful enhancements like better client handling and easier creation of CosmWasm contracts.
Features and enhancements 🧵
ALT The ibc-rs v0.52.0 release includes IBC's client-recovery mechanism, which provides a route to reinstate frozen or expired clients after a successful governance vote; a new "ibc-client-cw" crate that facilitates CosmWasm contract creation for light clients built using ibc-rs; and, bug fixes and optimizations.
IBC is expansive.
Chains connect directly to one another.
There's no transaction routing through a hub chain.
Peer-to-peer connections open up endless possibilities for blockchain interoperability.
Check out IBC transaction flows from the perspective of @osmosis.
IBC lets blockchains communicate peer-to-peer.
There's no third-party intermediary with a set of admin keys. No multisig wallet. No liquidity pool.
Just 24/7 permissionless data-sharing.
Because all blockchains deserve to communicate.
The IBC protocol extracts no fees from users, and never will. Instead, relayers pay the gas fees for key stages of the IBC packet lifecycle, ensuring network liveness.
Is this model sustainable?
🧵 on the changing fee landscape, featuring work by @osmosis@skipprotocol.
New Release: ibc-go v10
ibc-go v10 brings the official v2 of IBC Protocol.
It's the biggest upgrade to IBC since its launch in 2021: simpler, more flexible, and easier to implement across ecosystems ⚛️
Let's break it down 🧵👇
Rollups require secure and flexible interoperability infrastructure. What's best for that?
IBC 🤝 Rollups.

💥 New Release: 08-Wasm Client Module
Use a Wasm VM to host light clients as bytecode:
→ Write light clients in languages that compile to Wasm (Rust, C/C++, JS, Go, etc.)
→ Streamlined addition of new light clients
→ Easily instantiate clients for non-@CometBFT consensus
ALT The Wasm Client Module for IBC allows developers to easily add new light clients to their chain. It is a Wasm Virtual Machine that lets them host light clients as bytecode.
💥 New Release: ibc-go v9.0.0 with ICS-20 token transfers v2
New features: multi-token transfers within a single packet and native packet forwarding/unwinding.
These new features improve UX, increase composability between chains, and unlock new use cases.
What’s next for IBC?
IBC's vision is to be the TCP/IP for blockchains.
To get there, IBC will develop along two strategic pathways: expansion and usability.
Expansion: connecting to more ecosystems.
Usability: better DevX and feature-rich cross-chain workflows.

Developed for an enterprise TradFi use case, this client is an open-source solution for ZK-IBC interoperability between the @cosmos interchain and @ethereum.
In 2024, IBC will expand to new ecosystems.
One of the targets is the OP Stack, a framework built by @optimism, Ethereum's second-largest rollup.
But how do you port a well-defined interoperability protocol to the OP Stack framework?
A preview into architecture 🧵

Noble built a module that lets CEX users withdraw USDC to any IBC-enabled chain in 1 click.
When supported by CEXs, it will power fast + seamless USDC flow from accounts on CEXs like @binance, @okx , @krakenfx, or @kucoincom to ANY of the 118 chains in the interchain. 🏎️
5/ So how does forwarding bring about a 1 CLICK experience?
Instead of having to withdraw to Noble, then manually send USDC to a destination chain using IBC, a forwarding account on Noble does it for you automatically
Either a CEX or the user registers this forwarding account👇
The IBC team has updated the IBC Solidity contracts to v2.
