Optimism announces the first adjustment to OP Mainnet transaction ordering rules, kicking off a four-week experiment on 'stake-based priority ordering.' Previously, transactions were primarily sorted by 'highest Gas fee first.' The new mechanism allows participants to stake at least 100,000 OP tokens to the PolicyEngineStaking contract to secure priority block positions. In the first week of the experiment, a first-come, first-served approach will be used, while weeks two through four will introduce a time-weighted multiplier based on staking duration. Optimism stated that participation in the experiment is voluntary, and non-participants will see no changes to their transaction ordering rules. The existing priority Gas fee bidding mechanism will continue to operate as usual. https://(wublock123.com)/news/op-mainnet-first-change-tx-ordering-stake-100000-op-priority-blocks-61704
