v0.2.0

[owen-reorg]

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_fullnode if the layer 1 endpoint supports the eth_getTransactionReceiptsByBlockNumber API. This will significantly enhance the performance of retrieving L1 receipts (feat(op-node): add rpcKind bsc_fullnode for eth_getTransactionReceiptsByBlockNumber #63).
• The rollup configuration for opBNB Mainnet and Testnet has been added to the code. You can now use the --network=opBNBTestnet or --network=opBNBMainnet flag instead of --rollup.config=./rollup.json to specify the rollup configuration for the op-node. (feat(op-node): update l1 gas price with fixed value #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 (feat(op-node/op-batcher/op-proposer): add fallbackClient #55).
• Enable the layer 2 sync mechanism for opBNB by adding --l2.engine-sync=true flag 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. (feat: engine p2p sync feature #62)
