On Tuesday, the Optimism team announced via X that stake-based transactions are now live on OP mainnet.
Stake-based priority ordering is a four-week, opt-in experiment, approved by Optimism Governance earlier this month. Participants who stake ≥100,000 OP into the PolicyEngineStaking contract earn priority block positioning.
At the end of four weeks (June 23), OP Mainnet automatically reverts to standard PGA. The experiment runs in two phases:
-
Phase 1 (week 1): eligible stakers' transactions are ordered FIFO. First in, first positioned. Stake above the minimum has no impact.
-
Phase 2 (weeks 2–4): a stakeholder-weighted multiplier to your priority gas replaces FIFO. The longer you've staked, and the more you stake, the higher the multiplier (max 3x).
Up to 20% is reserved for this experiment, and unused blockspace flows back to normal transactions.
Optimism’s main utility is to batch transactions on the Optimism network. Optimism allows users to enjoy lower gas fees on their transactions executed on the Optimism network through optimistic roll-up technology.
Optimism (OP) is a layer-two blockchain on top of Ethereum. Optimism benefits from the security of the Ethereum mainnet and helps scale the Ethereum ecosystem by using optimistic rollups. That means transactions are trustlessly recorded on Optimism but ultimately secured on Ethereum.
Optimism is one of the biggest scaling solutions for Ethereum with over $500 million in TVL. It is home to 97 protocols, the biggest being Synthetix (SNX), a derivatives exchange, Uniswap (UNI), a DEX, and Velodrome (VELO), an AMM. Users can begin their journey on Optimism by adding the chain on their Metamask and bridging tokens like ETH to the L2. On May 31, 2022, Optimism conducted a highly anticipated airdrop of its OP token.
OP is trading at $0.1271, down 2.3% in the last 24 hours.
