Agreement Protocol

The Federated Byzantine Agreement (FBA) provides a way to reach agreement 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 agreement can be reached. FBA simultaneously enjoys four key properties: decentralized control, low latency, flexible trust, and asymptotic security.

A few ways to explore FBA:

  • To learn all about the protocol, read the white paper.
  • If you are implementing FBA, see the internet draft and send questions and feedback to the DIN mailing list.
  • View or contribute to the code in HC Net-core.
  • If white papers aren’t your thing, here’s a technical summary.
  • If you’re new to agreement, get the basics from our graphic novel, Adventures in Galactic agreement.
