Vitalik Buterin outlines Ethereum's long-term roadmap, predicting Lean Ethereum will be the third major iteration.
According to ChainCatcher, Vitalik Buterin recently reported that Ethereum researchers met in Berlin and updated the protocol's long-term roadmap (strawmap.org). Vitalik pointed out that "Lean Ethereum" is not a single upgrade, but a series of improvements to be implemented in phases over the next three to four years. Its importance is comparable to a "merge," encompassing the restructuring of almost every core module of the protocol. Key features include: Verification Mechanism: Introducing recursive STARKs to replace the existing direct re-execution method, becoming a core component of the protocol at the primary level; Quantum Security: Significantly elevated priority, all quantum-fragile components will be replaced, and the quantum-safe Blob design is underway; Consensus Layer: Decoupling the available chain from finality, achieving one to two rounds of finality, resulting in better security and lower latency; State Layer: Existing dynamic states remain unchanged, but new, more scalable states (such as UTXO storage, circular buffers, etc.) will be added. It is projected that by 2030, Ethereum will have 2 TB of dynamic states + 100 TB of new states, and the migration of applications such as ERC20 and NFTs can achieve a gas fee reduction of over 10 times; Privacy: Upgraded from an additional feature to a primary goal, permeating the design of Mempool, state trees, etc.; VM: In addition to the EVM, leanISA or RISC-V will be introduced, with the long-term goal being direct at the protocol layer.
Ethereum founder Vitalik Buterin transferred 79 ETH using Railgun.
PANews reported on July 3 that, according to Onchain Lens, Ethereum co-founder Vitalik Buterin transferred 79 ETH through the privacy protocol RAILGUN, which is worth approximately $137,000 at the current price.
Ethereum Founder Vitalik Buterin Says AI Won’t Doom Crypto Security
The Ethereum co-founder said AI could help developers mathematically verify entire software systems, turning the same technology powering new attacks into a tool for defense.
Vitalik, founder of Liquid, identified the anonymous documents by analyzing the habits of the mathematical and algorithmic explanations.
According to Foresight News , Vitalik Buterin tweeted that Liquid founder Franklyn Wang successfully identified his anonymized experimental document. In 2024, Vitalik wrote content in Chinese, then translated it into English using a local Qwen2.5 model, and finally manually corrected the translation issues to test whether it could effectively hide his personal writing style. Franklyn Wang successfully identified the anonymous document as originating from Vitalik by analyzing the unique habits in the mathematical and algorithmic explanations (such as specific numerical examples and attack scenario descriptions). According to a previous Foresight News report, Vitalik Buterin tweeted that his anonymity experiment had been going on for "13 days" and "no one has found it yet." He added that he encouraged people to "broaden their search scope slightly," noting that he had seen many search behaviors and AI scripts miss document categories that should have been included.

Vitalik Buterin released a new proposal suggesting that the consensus layer state be drastically reduced to only 6 bytes.
According to Foresight News , Vitalik Buterin has released a new proposal, "The Extremely Lean Chain." The core of this proposal is to significantly simplify the state stored by each validator in the current Beacon chain (public key, withdrawal certificate, activation/exit epoch, etc.), retaining only 6 bytes (1 byte for effective balance + 5 bytes for deposit tree index). Validators will need to track their deposit Merkle proofs themselves and asynchronously update their effective balance and participation records using daily generated STARK proofs, instead of having these updates processed in real-time on-chain every epoch. The proposal is planned to proceed in multiple phases: removing public key storage and replacing it with a deposit tree index, with daily STARK proofs used to update the balance; subsequently, a daily public key refresh mechanism will be introduced to achieve strong anonymity of validator identities, while naturally supporting Single Secret Leader Election (SSLE). This design is considered feasible in the context of Lean upgrades such as single-slot finality (SSF) and recursive STARK, aiming to significantly reduce consensus layer state overhead and computational burden, support the number of validators to the millions, and provide strong privacy protection in advanced versions.
