George Samman is a blockchain and cryptocurrency consultant and advisor who recently co-authored a seminal report on blockchain architecture with KPMG.
Here, Samman explains how the consensus algorithm achieved by Raft was finally fixed by its distant relative, Kadena.
This article covers Kadena’s blockchain. It 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.
