Honest Minority Assumption

Definition ∞ The honest minority assumption posits that a distributed system can maintain its security and integrity as long as a minority of its participants act honestly. This principle contrasts with the more common honest majority assumption found in many consensus protocols. It implies resilience even when a significant portion of the network is malicious.
Context ∞ The honest minority assumption is a critical concept in the design of certain advanced cryptographic protocols, particularly those employing zero-knowledge proofs or specific forms of Verifiable Delay Functions. Achieving security under this weaker assumption offers greater robustness against coordinated attacks or collusion. Research continually aims to construct protocols that operate securely with fewer honest participants.

$Three textured, translucent blocks, varying in height, stand in rippled water under a full moon. The blocks exhibit a gradient from clear to deep blue, suggesting evolving digital assets or tokenized real-world assets. Their fractured surface evokes the intricate blockchain architecture and robust cryptographic hashing securing decentralized ledger entries. The surrounding water, reflecting the blue hues, symbolizes DeFi liquidity pools and the underlying network infrastructure. The prominent moon signifies ambitious Web3 ecosystem growth and potential moonshot projects, while the pillars could represent distinct smart contract modules or network nodes contributing to market depth.$
