Ethereum is set to undergo a major upgrade that could improve the network’s scalability by transitioning to zero-knowledge (ZK) proofs for block validation. The move is to scale the network to process up to 10,000 transactions per second (TPS), drastically improving its speed and efficiency.
EIP-8025, or “Optional Execution Proofs”, will shift consensus to simple proof validation, lowering hardware requirements for validators, speeding up the validation process, and improving Ethereum’s overall scalability and decentralization.
Optional Execution Proofs’ Aim to Boost Ethereum Scalability
According to details shared by Ethereum Foundation member and researcher “ladislaus.eth”, Ethereum is going ahead with its L1-zkEVM 2026 roadmap, which removes the need for node validators to re-execute every transaction within a block to confirm its validity.
Since the blockchain’s genesis, every validating node has been independently repeating the same execution process. While it is definitely functional, it comes at a cost that scales linearly proportionate to the amount of on-chain activity. As Ethereum continues to grow and expand, the process will use more gas (GWEI) per block, which means more work per node, thereby increasing the storage, bandwidth, and processing requirements.
Instead of going through this cumbersome process, the new model allows validators to check a cryptographic proof that confirms whether the block was executed correctly. This means that nodes only need to verify the result, rather than redo the entire validation work themselves. The first L1-zkEVM workshop is scheduled for February 11, where developers will review the progress and decide on the next steps.
zkAttesters Aim to Reduce Validator Load on Ethereum
EIP-8025 does not replace Ethereum’s existing validation system; instead, it applies an alternative method, where validators can choose an option called “zkAttesters” to verify ZK execution proofs instead of running a full execution client. This would offer validators a lighter and more efficient way to confirm transactions. The proofs would then be shared across the network, and validators could accept a block after verifying a set number of matching proofs from different sources.
The proposed system makes life much easier for validators, as they no longer need to store and process all block data, and would only need to check for a proof. That equates to reduced workload, lower cost, and faster node setup, even on basic computers. This would mean more people could become Ethereum validators without investing in expensive hardware. It also improves client diversity, as proofs can be generated by different software systems, rather than relying on the main layer.
A core component of this transition is the upcoming “Glamsterdam” upgrade, which will remove penalties for delayed execution – a key cog that has historically discouraged nodes from validating ZK-proofs on Ethereum. Glamsterdsm will give validators more time to attest to blocks, offering them flexibility and increasing the chances of the Ethereum Foundation’s target of 10% of validators switching to validating proofs in 2026.
However, challenges remain, as proofs must be generated quickly and correctly because Ethereum will be more dependent on proof providers once EIP-8025 is implemented. Developers are currently testing the mechanism’s safety, speed, and reliability.
EIP-8025 Targets Fragmented Liquidity on Ethereum
According to Ethereum researcher Justin Drake, the validators most likely to make the switch are those operating lower-spec home-based systems for running nodes. Optional Execution Proofs will help improve scalability, as these devices will be able to participate widely in the block validation process.
Gary Schulte, senior blockchain engineer on Ethereum’s Besu client, said the new system will result in most of the heavy work being carried out by block builders and ZK-provers, freeing up validators to perform simpler verifications. This dynamic is set to create a more efficient system capable of supporting Ethereum’s higher transaction throughput.
Ethereum-based layer-2 scaling solutions like ZK-Sync are also beneficiaries of this transformation. ZK-Sync’s “Atlas” upgrade will leverage ZK-proofs to allow L2s to tap into Ethereum’s on-chain liquidity instantly, while inheriting the security of the mainnet. It aims to address fragmented liquidity across multiple L2 ecosystems, enabling faster and more efficient transactions.
The proposed Ethereum Interoperability Layer (EIL) will further improve the interoperability between the Ethereum mainnet and its L2 ecosystems. This will ensure that funds can be moved seamlessly across different networks. Enhanced interoperability will pave the way for more efficient decentralized finance (DeFi) applications on Ethereum.
At the time of writing, Ether (ETH) is trading at $2,015 – down 1.23% in 24 hours.
