Vitalik Buterin, the co-founder of Ethereum, unveiled this Monday what he describes as the biggest overhaul of the network since The Merge. Dubbed “Lean Ethereum,” this reconstruction plan aims to radically simplify the protocol’s architecture while strengthening its decentralization and security. Ecosystem developers welcome this strategic vision but are calling for faster execution to avoid losing their competitive edge against other layer-1 blockchains that are rapidly gaining ground.
Lean Ethereum: A Deep-Rooted Overhaul
Announced in a detailed blog post and during a virtual Ethereum developers conference, the “Lean Ethereum” project represents a paradigm shift for the network. Buterin proposes reducing the technical complexity accumulated over the years by simplifying the Ethereum Virtual Machine (EVM) code, removing features that have become obsolete, and optimizing the way transaction fees are managed.
This overhaul is compared to a thorough “spring cleaning” of the protocol. Since The Merge in September 2022, Ethereum has accumulated several layers of complexity: EIP-1559 for fee management, layer-2 rollups, proto-danksharding (EIP-4844), and numerous minor updates along the way. According to Buterin, the code has become too heavy and difficult to maintain, hindering innovation and exposing the network to long-term security risks. “We need a simpler, more robust, and easier-to-evolve Ethereum,” he stated.
The proposed changes include removing the SELFDESTRUCT mechanism from the EVM, simplifying the transaction format, and reducing the number of precompilations (special contracts embedded directly into the protocol). Buterin also proposes standardizing the staking reward system to make it more predictable and equitable for all participants. According to initial estimates, these modifications could reduce the protocol’s source code size by approximately 30 to 40 percent, while also improving overall performance.
Developers Approve but Want More Speed
The reaction from the Ethereum developer community is broadly positive. Several prominent contributors, including members of the Ethereum Foundation and client teams such as Geth and Lighthouse, have praised Buterin’s strategic vision. “This is exactly what Ethereum needs — bold simplification rather than superficial fixes,” commented a lead developer from the Geth team.
However, a consensus is also emerging around the need for rapid execution. Many developers believe Buterin’s proposed timeline of 12 to 18 months is too long. “The layer-1 market is evolving extremely quickly. Solana, Aptos, and Sui are advancing at a sustained pace, and we simply cannot afford to wait two years,” warned a notable contributor. The general sentiment is that the core of “Lean Ethereum” — the most impactful changes — should be implemented within 6 to 9 months, with additional optimizations to follow afterward.
One potential friction point concerns governance. Implementing such deep changes requires broad community consensus, which can inevitably slow down the process. Buterin has suggested using bundled EIPs (Ethereum Improvement Proposals) to accelerate decisions, but some developers fear this approach might bypass the open debate process that has historically been Ethereum’s greatest strength.
Bitmine Adds $74 Million in Ethereum
Meanwhile, miner and investment firm Bitmine announced the acquisition of an additional $74 million in Ethereum, bringing its total holdings to over $320 million in ETH. This decision comes as Ethereum’s price fluctuates between $1,749 and $1,808, a level considered attractive by long-term institutional investors. Bitmine, which has diversified from Bitcoin mining into Ethereum infrastructure investment, views this accumulation as a strong vote of confidence in the protocol’s future and in Buterin’s “Lean Ethereum” vision.
“Bitmine’s commitment sends a strong signal to the market,” analyzes a London-based trader. “When a major industry player invests $74 million in a single transaction, it indicates deep conviction in the direction Ethereum is taking.” The acquisition was carried out through several centralized exchanges and OTC purchases, suggesting a strategy of discreet accumulation before the official announcement of the Lean Ethereum plan.
A Favorable Market Context for Ethereum
Ethereum’s price is holding around $1,750 to $1,808 as of July 6, 2026, with daily trading volume up by 35 percent following the announcement. ETH options show growing open interest for strikes at $2,000 and $2,500 expiring in September, indicating that traders expect the rally to continue in the coming months.
This bullish momentum is supported by several fundamental factors. The number of active addresses on Ethereum has reached a yearly high of 620,000 daily addresses, a clear sign of growing adoption. Transaction fees, while still moderate thanks to layer-2 rollups, generate stable and reliable revenue for validators. The staking participation rate now exceeds 32 percent of the total ETH supply, further strengthening network security.
