Ethereum Foundation Shifts zkEVM Focus to Security Roadmap

The Ethereum Foundation announced a strategic pivot in its development priorities on December 18, focusing on enhancing security for zero-knowledge Ethereum Virtual Machines, or zkEVMs, rather than solely pursuing faster transaction speeds. The foundation outlined a three-stage roadmap culminating in 128-bit provable security by the end of 2026, a standard aligned with recommendations from cryptographic authorities to safeguard the blockchain against sophisticated threats.

This shift follows significant performance advancements in zkEVM technology. Over the past year, teams have reduced proof generation times from 16 minutes to 16 seconds per Ethereum block, slashing costs by 45 times. As a result, 99 percent of mainnet blocks can now be proven in under 10 seconds on standard hardware costing around $100,000 and consuming less than 10 kilowatts of power. These improvements, benchmarked on the EthProofs platform, enable validators to verify blocks without disrupting network liveness, which operates on 12-second slot times.

However, the foundation emphasized that these gains have highlighted underlying vulnerabilities. Many zkEVM designs, particularly those based on STARK...
