IBC stands for inter-blockchain communication and it is a tool that allows blockchains with separate consensus layers to communicate with each other. Antelope IBC is an inter-blockchain communication protocol that is fully trustless. The end user is the carrier of all of the proof elements required to demonstrate that the action took place on the source blockchain and prove it on the destination blockchain.   Utilizing this, Antelope blockchains can reach consensus on the state of assets across other networks in the ecosystem, without the need for third-party bridges or oracles. This enables functions such as cross-chain bridging and side-chains for horizontal scaling, in a way that is much more secure and immutable than other solutions on the market.
