According to Vitalik Buterin, the co-founder of Ethereum, blockchain security depends not only on stage 2 protocol improvements but also heavily on the quality of the underlying proof system, as highlighted in his recent tweet (source: @VitalikButerin, May 5, 2025). For traders, this underscores the necessity of evaluating both protocol upgrades and the robustness of cryptographic proofs when assessing blockchain project security. This insight is particularly relevant for those trading tokens linked to zero-knowledge proofs and rollups, as vulnerabilities in the proof system could directly impact asset risk and price stability.
