Ethereum co-founder Vitalik Buterin has clarified misconceptions surrounding 51% attacks in a recent post, emphasizing that such attacks cannot render an invalid blockchain valid. Buterin highlighted that colluding validators are unable to steal user assets on-chain, although risks persist if users delegate decision-making to a validator set. He noted that while slashing increases the cost of collusion, it does not completely eliminate the risk. Buterin's comments have sparked renewed discussion on the limitations and risks associated with blockchain consensus mechanisms. Some community members speculated that his remarks might reference EigenLayer, though Buterin did not confirm this connection.
