The Block Collider multichain is a high-speed distributed ledger built on sets of blocks from other blockchains, integrating those chains together and enabling many cross-chain features. The multichain supports ultra-low latency balance updates with the Financial Information eXchange (FIX) protocol and innovates on reduplication of work and incentives for miner network speed, so that the resulting multichain pushes the frontier of speed and throughput of blockchains. The Block Collider multichain is collaboratively created exclusively by decentralized peer-to-peer miners — with no centralized points of failure, oracles, or validators.
