PANews reported on November 12th that Bybit's Lazarus Security Lab released a report stating that 16 mainstream blockchains already have mechanisms in their code that can freeze or restrict user funds, and another 19 blockchains can achieve similar functionality through minor protocol modifications. The report identifies three types of freezing mechanisms: hard-coded freezing (such as BNBChain and VeChain), configuration-based freezing (such as Sui and Aptos), and contract-based freezing (such as HECO). Notably, Sui froze $162 million in stolen assets after the Cetus incident, and BNBChain prevented a $570 million cross-chain bridge attack through a blacklist mechanism. David Zong, Bybit's head of risk control, stated that transparently disclosing these mechanisms helps the industry build trust and improve governance.
