Definition ∞ Sequencing reform refers to proposed or implemented changes to how transactions are ordered and processed within a blockchain or its scaling layers. These reforms often seek to address issues like front running, MEV extraction, or transaction censorship by altering the rules or participants involved in transaction sequencing. The goal is to create a more fair, efficient, and resilient transaction ordering process.
Context ∞ News about sequencing reform is particularly relevant in discussions surrounding blockchain fairness and the mitigation of adverse MEV effects, especially on networks like Ethereum and its Layer 2 solutions. Various proposals, such as proposer-builder separation (PBS) or alternative mempool designs, are being explored to decentralize and improve transaction ordering. The success of these reforms significantly impacts user experience and the overall integrity of decentralized markets.
