## Byzantine Fault Tolerance

Byzantine Fault Tolerance is a property of a system that enables it to reach consensus even when some of its components fail or act maliciously. In the context of blockchain and financial protocols, this ensures that the network continues to operate correctly as long as a certain threshold of nodes remains honest.

It addresses the challenge of nodes providing conflicting information to different parts of the network, which is essential for maintaining a consistent financial ledger. Without this, a malicious actor could attempt to spend the same funds twice or manipulate transaction history.

The mechanism requires nodes to communicate and verify each other's messages before committing a transaction to the chain. This is fundamental for the security of decentralized margin engines and settlement layers.

It ensures that the system remains robust against coordinated attacks or network partitions. Achieving this tolerance is a prerequisite for any secure, decentralized financial infrastructure.
