Byzantine Generals Problem

Consensus

The Byzantine Generals Problem describes the fundamental challenge of achieving reliable consensus among distributed parties where some participants may be unreliable or malicious. In the context of cryptocurrency, this problem highlights the difficulty of ensuring all nodes agree on the validity and order of transactions without a central authority. The solution, implemented through consensus mechanisms like Proof-of-Work or Proof-of-Stake, ensures that the network maintains a single, immutable state of the ledger.
