Ethereum Foundation Introduces Execution Tickets to Address PBS Monopoly

Barnabé Monnot, head of the Robust Incentives Group (RIG) at the Ethereum Foundation, unveiled the 'Execution Tickets' mechanism at the EthCC[9] conference. According to Foresight News, Monnot highlighted that the current PBS architecture grants excessive monopoly power to block proposers. Execution Tickets aim to auction the execution and ordering rights of transactions within blocks to ticket holders at the protocol level, leaving validators with only signature and consensus functions, thus removing their direct involvement in MEV distribution. Economically, the revenue from selling Execution Tickets will be directly burned by the protocol, similar to the EIP-1559 mechanism. This approach redistributes MEV profits, originally concentrated among a few high-level participants, in a deflationary manner to all ETH holders. For validators, the interception of MEV revenue by the ticket market will lead to smoother and more predictable income, eliminating the need for complex MEV-Boost plugins or the pursuit of hardware and network advantages, significantly lowering the participation threshold for home stakers. Monnot emphasized that Execution Tickets are a core proposal in Ethereum's roadmap phase 'The Scourge,' which, along with inclusion lists and other mechanisms, will effectively prevent specific builders from censoring transactions.
