According to Wu, Chaos Labs CEO Omer shared the Sybil analysis principles and methods. His goal is to focus on industrialized Farmers, mainly relying on the source of funds analysis heuristic method. Layer Zero has 4.82 million EVM users, of which about 14.5% are listed as Sybil users. Identification methods include detecting the source of funds, initial entity identification (users who received funds from the same source within 24 hours), detecting fund anomalies (funding more than X wallets within 24 hours, Txs from the same source, and behavioral similarity), behavioral patterns/similarity vectors for clustering, behavioral pattern expansion (number of transactions, number of on-chain applications, multi-chain similar activities, and average transaction volume), further strictness of cluster identification, Sybil classifiers for the same source of funds-concentration requirements (Silhouette Score>0.7), Sybil classifiers-size requirements (meeting the requirements of relative scale and threshold size at the same time).
