NODE: SYBIL-ATTACK
VERIFICATION: PASSED
01_DEFINITION
Strict Definition
"A type of attack where a single actor creates multiple fake identities (accounts) to gain disproportionate influence or rewards in a decentralized network."
Liability Check // Risk Analysis
The 'Governance Manipulation' risk. If a DAO's voting is based on 'one account, one vote,' a Sybil attacker can overwhelm the legitimate community to pass malicious proposals. It also dilutes airdrop rewards for real users.

Strategy Domain
"Use 'Proof of Personhood' or identity verification (e.g., Gitcoin Passport, Worldcoin) to ensure users are unique individuals."
Operations Standard
"Favor 'Token-Weighted' voting or 'Reputation-Based' governance over simple account-based voting to increase the cost of an attack."
Legal & Compliance
"Monitor for 'Cluster Activity'—multiple wallets funded from the same source—as a sign of Sybil-based fraud."
