Definition ∞ A decentralized attack describes a coordinated malicious action against a distributed system, such as a blockchain network, where the attackers operate without a single point of control. Unlike traditional centralized attacks, these threats often leverage the distributed nature of the system itself, such as a 51% attack on a proof-of-work blockchain or sybil attacks against decentralized governance. The goal is to disrupt network operations, compromise data integrity, or gain undue influence over the system.
Context ∞ Reports on network vulnerabilities or protocol upgrades frequently address the potential for and mitigation strategies against decentralized attacks. The discussion centers on strengthening consensus mechanisms and improving network decentralization to resist such coordinated threats. Future developments aim to design more robust and attack-resistant distributed ledger technologies, especially as networks grow in complexity and value.
