Optimism tests pledge based transaction sorting mechanism in Sepolia

According to Optimism, the OP mainnet has experimented for the first time with a staking based transaction sorting mechanism, which has been tested online on Sepolia. Users can obtain priority access to the top of the block by pledging OP, without the need for lock up or administrator control of funds, and support instant release of pledges. The experiment is divided into two stages: in the first stage, 100000 OPs are pledged and given the same priority, sorted on a first come, first served basis; In the second stage, a weighted score of pledge amount, duration, and priority gas fee is introduced, with a maximum advantage of three times, and a decreasing return mechanism is set up to resist lightning loan attacks. The experiment can be rolled back to standard sorting at any time without affecting staking withdrawals, and the test results will determine whether to launch it on the main website.
