Stellar Consensus Protocol
The Stellar Consensus Protocol (SCP) provides a way to reach consensus without relying on a closed system to accurately record financial transactions. SCP 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. SCP simultaneously enjoys four key properties: decentralized control, low latency, flexible trust, and asymptotic security.
A few ways to explore SCP:
- Start out with the peer-reviewed paper in SOSP 2019 on Stellar for a technical overview.
- To learn all about the Stellar Consensus Protocol, read the original white paper.
- A Simplified SCP description is shorter and easier to read than the full whitepaper.
- If you are implementing SCP, see the internet draft and send questions and feedback to the DIN mailing list.
- View or contribute to the code in stellar-core.
- If white papers aren’t your thing, here’s a technical summary.
- To learn about the SCP voting process, read this blog post or watch this talk.
