Chainweb is the public blockchain of Kadena, a company that builds blockchain systems that was founded by Will Martino and Monica Quaintance. Chainweb is a blockchain architecture which combines many Proof-of-work blockchains together using a single cryptocurrency and cross chain Special-Purpose Vehicle (SPV) transfers at the smart contract level. The Chainweb architecture provides high levels of Proof-of-work throughput while maintaining a constant global hashrate and energy requirement. Benchmark testing of the Chainweb protocol has demonstrated that it can operate 1000+ blockchains at once and process approximately 10,0000 transactions per second.
