BFT Consensus Architectures

Consensus

Byzantine Fault Tolerant architectures serve as the foundational mechanism for distributed ledgers to achieve transactional agreement despite the presence of malicious or malfunctioning nodes. These protocols require a threshold of participant agreement to validate blocks, ensuring that the ledger remains tamper-proof even if a fraction of the network behaves inconsistently. In the context of high-frequency cryptocurrency markets, this architecture provides the deterministic finality required to prevent double-spending and maintain the integrity of order books.
