Vitalik Releases Ethereum Purge Roadmap: 3-4 Year Overhaul Prioritizes Quantum Resistance and Privacy

According to Vitalik Buterin, Ethereum researchers finalized the Ethereum Purge roadmap two weeks ago at a Berlin conference. The roadmap is a multi-year series of forks spanning 3-4 years starting with I-star, replacing most core components as Ethereum's third major phase. Key changes include transitioning verification from direct execution to recursive STARK, introducing 1-2 rounds of finality in consensus, implementing multidimensional gas pricing, and replacing the current cryptography with quantum-resistant algorithms across the protocol.

The state model will expand from its current ~2TB capacity to 100TB by introducing UTXO and ring buffers, reducing transaction fees by over 10 times for applications like ERC20, NFT, and DeFi. Complex applications such as Uniswap pools will retain legacy state with no forced migration. Privacy is being elevated to a first-class design objective, with all new components requiring quantum-resistant and non-custodial privacy transaction support.
