EIP-8105 proposes a scheme-agnostic encrypted mempool for Ethereum, designed to hide transaction payloads until after inclusion and reduce harmful MEV. Sandwich attacks cost Ethereum users an estimated $60 million per year. Transactions broadcast to the public mempool are publicly visible before inclusion, which gives MEV bots the ability to affect the order of transactions and insert their own for profit. This problem has persisted on some level in spite of years of discussion and various out-of-protocol mitigation attempts. Encrypting mempool transactions would be one of the most compelling solutions to prevent MEV. While this idea has been actively discussed for years, it has not yet been implemented at the protocol level. In our earlier research, we examined several proposals based on threshold-encryption, including Shutter, Batched Threshold Encryption, and Flash Freezing Flash Boys. In this article, we turn to a meta proposal titled “Universal Enshrined Encrypted Mempool (EIP-8105)“. Universal Enshrined...
The UK financial regulator has launched a consultation on crypto rules covering stablecoins, trading and staking ahead of a broader UK crypto regime expected to take effect in 2027. The United Kingdom’s Financial Conduct Authority (FCA) said Wednesday it is consulting on guidance for the country’s future crypto regime, in the latest step toward a broader framework that is expected to take effect on Oct. 25, 2027. In a statement, the FCA said it is seeking industry feedback on the guidance to help companies understand how they might be affected by the regime. The full consultation text is available on the FCA website, with the feedback window closing on June 3, 2026. The regulator said the guidance will clarify requirements for areas such as stablecoin issuance, crypto trading, custody and staking. “We want to develop a competitive and sustainable cryptoasset sector where UK consumers are served by authorised cryptoasset firms and can make informed decisions,” the FCA said.
