The Federated Byzantine Agreement (FBA) provides a way to reach consensus without relying on a closed system to accurately record financial transactions. FBA has a set of provable safety properties that optimize for safety over liveness—in the event of partition or misbehaving nodes, it halts progress of the network until consensus can be reached. FBA simultaneously enjoys four key properties: decentralized control, low latency, flexible trust, and asymptotic security.
A few ways to explore FBA:
