An honest majority refers to a fundamental assumption in many distributed consensus protocols, particularly in Byzantine Fault Tolerant systems. It posits that more than two-thirds of the network participants are behaving honestly and following the protocol rules. This condition is necessary to ensure the network can reach agreement and operate correctly, even in the presence of malicious actors. The security of the system relies on this majority.
Context
The concept of an honest majority is a critical security parameter in blockchain design and is frequently referenced in discussions about network decentralization and attack vectors. Any news regarding potential 51% attacks or Sybil attacks directly relates to the integrity of the honest majority assumption. Maintaining a robust honest majority is essential for the long-term security and reliability of a decentralized ledger.
New protocols for Asynchronous Verifiable Secret Sharing (AVSS) leverage lightweight primitives to achieve optimal resilience and amortized linear communication, fundamentally accelerating BFT consensus.
