Vital factors
- The Ethereum Basis prioritizes safety over velocity, aiming for 128 bits of provable safety by the tip of 2026.
- A 3-step roadmap was outlined, requiring the zkEVM group to make use of official instruments and meet progressive safety thresholds.
The Ethereum Basis has shifted its focus from efficiency to safety, setting a objective of 128-bit provable safety for L1 zkEVM by the tip of 2026. We require collaborating zkEVM groups to undertake standardized safety measurement instruments and develop a three-step roadmap to attain our targets.
The primary part focuses on an built-in safety evaluation in early 2026. The second part targets at the least 100 bits of provable safety by mid-2026, with outlined proof measurement limits. The ultimate stage would require full 128-bit provable safety with smaller proofs and formal soundness arguments by the tip of 2026.
As latest advances in cryptography have made these targets achievable, the authors emphasize that stabilization of the zkEVM structure is crucial to allow formal verification and long-term safety, marking a transition from efficiency experimentation to elementary robustness.
