Definition ∞ The honest majority assumption posits that more than half of the participants in a decentralized network will act honestly and follow the protocol rules. This fundamental principle underpins the security of many blockchain consensus mechanisms, particularly in proof-of-work and proof-of-stake systems. It guards against malicious actors attempting to subvert the network.
Context ∞ News reports frequently reference the honest majority assumption when discussing the security and decentralization of various blockchain protocols. Debates often center on the practical feasibility of maintaining such a majority in large-scale networks. Concerns arise if economic incentives or political pressures could compromise this crucial security premise.
