IBC-Tables is a repository dedicated to visualizing all active Inter-Blockchain Communication (IBC) connections, also known as IBC paths, in the Interchain ecosystem.
An IBC path is a series of entities that facilitate communication between two independent blockchains in the Interchain ecosystem. Each IBC path consists of a client, a connection, a port, and a channel:
-
Client: A light client is a piece of software that can verify the consensus transcript of a blockchain. Each IBC connection is associated with a pair of light clients: one light client on the source chain and one on the destination chain. Each light client verifies the consensus of the other chain.
-
Connection: Once a client is created on a chain, a connection can be established between the clients of two chains. This connection is bidirectional and can facilitate packet transmission in both directions.
-
Port: A port represents a module or subset of modules within a blockchain application that has been assigned as the end application of the IBC connection. Any module within the blockchain application can own a port and thus manage its own IBC connections.
-
Channel: A channel is a pipe that allows the exchange of packets between two specific modules on two different chains, under the governance of a specific connection.
This repository contains scripts that run daily workflows to fetch and update IBC connection data for each chain of the Cosmos chain-registry ⚛️. The data is fetched from each chain's public REST endpoint, processed, and stored in this repository. The script uses public nodes behind the REST relay provided by cosmos.directory ❤️
The repository is primarily organized around the chains in the Cosmos chain-registry. Each chain has its own folder, and within each folder is a CSV file containing the latest IBC connection data for that chain.
The repository uses GitHub Actions to run daily workflows that update the IBC connection data. The workflow is specified in the mainnets.yml file located in the .github/workflows directory.
