► About IBC
Inter-Blockchain Communication Protocol (IBC) is a fundamental paradigm shift in interoperability, allowing for arbitrary data transfer across blockchains in a trust-minimized, secure, and extensible manner. 

While incubated within the #Cosmos ecosystem, IBC is now being adopted across blockchain ecosystems - from Polkadot and Kasuma, to NEAR Protocol, Hyperledger and Corda blockchain.
