This is a hardfork release for the opBNB Testnet called Fermat.
It will be activated at block height 12113000, expected to occur on November 3, 2023, at 6 AM UTC.
User Facing Changes
- The L1 gas price of all L2 transactions will be fixed(3 Gwei by default and 5 Gwei for Testnet).
- Introduce a new type of RPC kind called
bsc_fullnode. To enable it, include the parameter--l1.rpckind=bsc_fullnodeif the layer 1 endpoint supports theeth_getTransactionReceiptsByBlockNumberAPI. This will significantly enhance the performance of retrieving L1 receipts (#63). - The rollup configuration for opBNB Mainnet and Testnet has been added to the code. You can now use the
--network=opBNBTestnetor--network=opBNBMainnetflag instead of--rollup.config=./rollup.jsonto specify the rollup configuration for the op-node. (#65) - Allow the addition of multiple L1 endpoints in the configuration. For example:
--l1=https://data-seed-prebsc-1-s1.binance.org:8545,https://data-seed-prebsc-2-s2.binance.org:8545,https://data-seed-prebsc-2-s3.binance.org:8545. By default, it will use the first endpoint, and if it's unavailable, it will automatically switch to the next one (#55). - Enable the layer 2 sync mechanism for opBNB by adding
--l2.engine-sync=trueflag on the op-node. Additionally, a new flag l2.skip-sync-start-check is introduced to allow users to skip the sanity check of L1 origins for unsafe L2 blocks when determining the sync-starting point. (#62)
