Definition ∞ Validator manipulation describes actions taken to improperly influence or control the behavior of network validators in a blockchain system. This can involve compromising validator nodes, engaging in collusion, or exploiting consensus mechanisms to achieve an unfair advantage or disrupt network operations. Such actions pose a direct threat to the integrity and security of decentralized networks.
Context ∞ Concerns regarding validator manipulation are frequently discussed in the context of proof-of-stake (PoS) blockchains and decentralized governance. News reports may highlight instances of alleged validator collusion, governance attacks, or the discovery of vulnerabilities that could permit such manipulation. Maintaining validator integrity is paramount for preserving the trust and security assumptions of these distributed systems.
