Key facts
- Ethereum is preparing for a significant network overhaul called 'Lean Ethereum'.
- The overhaul, led by Vitalik Buterin, aims to replace most major protocol components over three to four years.
- Key priorities include enhancing quantum resistance and privacy.
- The plan involves adopting recursive STARKs for more efficient transaction verification.
- Ethereum will introduce new, scalable state types while moderating the growth of current flexible state.
- The network may eventually transition to a virtual machine beyond the current EVM.
Ethereum is gearing up for its most substantial architectural changes since the 2022 Merge, with co-founder Vitalik Buterin detailing a multi-year initiative known as 'Lean Ethereum.' This ambitious plan aims to replace nearly every core component of the network over the next three to four years, with a strong emphasis on enhancing quantum resistance and privacy.
Buterin's updated roadmap, discussed at recent research meetings in Berlin and Svalbard, elevates quantum safety and privacy to primary goals. The network will see its cryptography redesigned, including the data storage mechanisms crucial for layer-2 rollups. This proactive approach addresses the potential threat of quantum computers breaking current blockchain security, even though such capabilities are still years away.
Privacy is being integrated as a default feature, enabling intermediary-free transactions. To improve scalability and reduce the burden on nodes, Ethereum will adopt recursive STARKs, a cryptographic proof method allowing for efficient verification of computations. This will enable nodes to confirm transactions without re-executing them, making the network faster and lighter.
A significant aspect of the 'Lean Ethereum' plan involves managing the network's 'state'—the blockchain's complete record of all data. The proposal is to cap the growth of the current flexible state while introducing new, more restrictive, and scalable state types. This strategy aims to increase the network's capacity to over 100 terabytes by 2030 without overwhelming individual nodes, thereby preserving decentralization.
Furthermore, Ethereum may eventually evolve beyond its current Ethereum Virtual Machine (EVM). Buterin indicated that a new virtual machine, potentially based on architectures like RISC-V, could replace the EVM as the primary engine for smart contracts, though this transition is considered a longer-term prospect. Capacity increases are also slated through upcoming upgrades like Glamsterdam and Hegotá, signaling a steady rise in transaction limits and data handling capabilities over the next five years.
The 'Lean Ethereum' roadmap represents a long-term commitment to future-proofing the network, prioritizing quantum defense and privacy well ahead of industry-wide adoption. This development comes as ether has seen a notable price increase, rising over 12% in the past week to approximately $1,777.
