BlockBeats news, on December 21, the Ethereum Foundation stated that it will shift its focus from speed to security in 2026 and set strict 128-bit encryption rules. The foundation claims that zkEVM has made significant progress in performance over the past year, but some solutions rely on insufficiently validated mathematical assumptions, theoretically presenting the risk of on-chain state being forged. Therefore, the more important work in the next phase is to strengthen formal verification, anti-attack capabilities, and basic cryptographic security.
The foundation will provide security review and assessment tools in the future, requiring zkEVM to achieve a minimum of 128-bit security strength before 2026, which is the current mainstream cryptographic recognition level. The new standard may slow down the progress of some scale expansion projects, but the foundation emphasizes that in the long run, resistance to attacks and credibility are important prerequisites for attracting institutions and high-value applications, focusing on security first before improving performance.
