## Byzantine Quorum Intersection

Byzantine quorum intersection is the mathematical requirement that any two sets of nodes (quorums) involved in a consensus decision must overlap by at least one honest node. This overlap is what prevents the network from splitting into two conflicting versions of history.

It is the structural safeguard that ensures the safety of the ledger in the presence of Byzantine faults. If quorums do not intersect correctly, the system can reach different conclusions simultaneously, leading to a catastrophic failure of consensus.

This principle is fundamental to the design of Byzantine fault tolerant protocols. It dictates how many nodes must be honest for the system to remain secure.

In the context of financial settlement, quorum intersection provides the assurance that a transaction is valid and recognized by the entire network. It is a core concept in protocol physics, ensuring that the system behaves as a coherent whole.

Designing systems with strong quorum intersection is essential for protecting the integrity of global digital assets.
