Key Takeaways:
A new proposal, EIP-8105, was introduced to the Ethereum ecosystem on April 15, 2026, outlining a design for a scheme-agnostic encrypted mempool aimed at curbing harmful Maximal Extractable Value (MEV).
"The core idea is to obscure transaction payloads from validators until after they are committed to a block," one of the EIP's authors said in the official proposal. This prevents MEV actors from front-running or creating sandwich attacks on user transactions.
The proposal suggests a new transaction type that includes a one-time public key for encryption, allowing block builders to include transactions without seeing their contents. The transaction can only be decrypted after the block is finalized, a move designed to level the playing field for all Ethereum users. The scheme-agnostic nature of the EIP means that various encryption approaches can be developed and utilized, fostering innovation in MEV mitigation.
The implementation of EIP-8105 could significantly enhance transaction privacy and security on the Ethereum network. However, it also stands to disrupt the existing business models of validators and specialized MEV infrastructure providers like Flashbots, who profit from the current MEV extraction landscape. The debate will now focus on whether the benefits of a fairer and more secure network for the average user outweigh the potential revenue loss for these established players.
