Evolution of Kadena, first real private blockchain

Kadena’s blockchain uses ScalableBFT to offer high-performance (8,000-12,000 transactions per second) with full replication and distribution at previously impossible scales (the capacity for more than 500 participating nodes). This, along with the multi-layered security model and incremental hashing allow for a truly robust blockchain. Based on Raft and Juno, Kadena embeds a full smart contract language (Pact) into its blockchain that can be run as either public (plain text) or private (double-ratchet encrypted) transactions.
