Vitalik Buterin Details Lean Ethereum Roadmap Prioritizing Privacy, Quantum Safety, and Validator Privacy on July 6

According to Vitalik Buterin, Ethereum's Lean Ethereum roadmap, detailed on July 6, places native privacy as a core protocol goal and spans a three to four-year planning horizon. The roadmap integrates privacy into base network consensus, transactions, validator records, and state storage while introducing quantum-safe cryptography and validator privacy mechanisms.

The plan proposes STARK-based verification to reduce validator state requirements and validator identity rotation using fresh public keys daily. The roadmap targets state growth reaching 100TB by 2030 and outlines transitions from current cryptographic systems like ECDSA and BLS signatures to post-quantum alternatives for long-term security.
