Vitalik Buterin Warns: Blockchain Security Ends When Off-Chain Tasks Begin

Ethereum co-founder Vitalik Buterin has issued a critical warning about the limitations of blockchain security, emphasizing that it ends when validators are tasked with off-chain activities. According to his recent statement, even if 51% of validators control the network, they cannot manipulate block creation or steal on-chain assets. This highlights the importance of reducing reliance on external services like bridges and oracles for secure operations.
