## Practical Byzantine Fault Tolerance

Practical Byzantine Fault Tolerance, or pBFT, is a consensus algorithm that provides high performance and low latency for distributed networks. It works by having nodes communicate through multiple rounds of voting to reach agreement, making it well-suited for permissioned or consortium blockchains.

Because pBFT offers deterministic finality, it is an excellent choice for financial systems that require immediate settlement of derivatives and other complex instruments. However, it is limited by the number of participants, as the communication overhead increases significantly as the network grows.

It remains a key technology for institutional-grade blockchain implementations.
