Catchain, Free TON House,

Catchain is a consensus protocol built on top of the TON Network broadcast protocol.

The name comes from the abbreviation catch-chain, since the main purpose of this protocol is to capture all events important for the consensus protocol (BCP).

The Catchain protocol provides secure broadcast communication over the TON Network between groups of validators for masterchain or shardchain dedicated to generating validation and propagation of blocks.

In a broad sense, the name Catchain hides two protocols: one of them is a lower-level (Catchain in a narrower sense), the second is a high-level Block Consensus protocol (BCP).
