According to data analysis platform X-explore, the anti-Sybil rules in Arbitrum's airdrop created a "major loophole", resulting in approximately 150,000 Sybil addresses and at least 4,000 Sybil communities profiting more than 253 million tokens, accounting for 21.8% of the total airdrop.
According to X-explore, Arbitrum's rules are: exclude cross-chain bridges, centralized exchanges, and smart contracts when detecting Sybil; adopt relatively tolerant detection for small-scale, same-person addresses; only data before the snapshot (February 6, 2023) is used for Sybil detection; only data from Arbitrum and Ethereum is used for Sybil detection, while data from other Ethereum Layer 2, such as Optimism and Polygon, is ignored. These Sybil detection rules will cause major vulnerabilities. According to the above rules, X-explore detects Sybil address data through its internal same-person address/Sybil address recognition model. #Web3 #Binance
