Optimism proposed piloting an experimental stake-based transaction ordering system on its network. The mechanism allows users to stake OP tokens in a smart contract to give a chosen address priority in transaction ordering. The pilot will test how the model affects user behavior, especially among bots and market makers.

The proposed ordering mechanism aims to create new utility, increase demand for OP tokens, and improve network efficiency. During the experiment, priority will depend on the amount and duration of OP staked. The system is currently live on the OP Sepolia testnet and will run for up to four weeks on mainnet. After the pilot, OP Mainnet will revert to the standard priority gas auction (PGA) system.
