Sync OP Mainnet
To sync OP mainnet, the Bedrock datadir needs to be imported to use as starting point. Blocks lower than the OP mainnet Bedrock fork, are built on the OVM and cannot be executed on the EVM. For this reason, the chain segment from genesis until Bedrock, must be manually imported to circumvent execution in reth's sync pipeline.
Importing OP mainnet Bedrock datadir requires exported data:
- Blocks [and receipts] below Bedrock
- State snapshot at first Bedrock block
Manual Export Steps
See https://github.com/testinprod-io/op-geth/pull/1.
Output from running the command to export state, can also be downloaded from https://datadirs.testinprod.io/world_trie_state_op_mainnet_b2c2b6e7edb919a0b856b9fd9aa02b11ead5305e63cdb33386babd82b9bc4cfe.jsonl.zst.
Manual Import Steps
1. Import Blocks
Imports a .rlp file of blocks.
Import of >100 million OVM blocks, from genesis to Bedrock, completes in 6 hours.
./op-reth import-op <exported-blocks>
2. Import Receipts
This step is optional. To run a full node, skip this step. If however receipts are to be imported, the corresponding transactions must already be imported (see step 1).
Imports a .rlp file of receipts, that has been exported with command specified in
https://github.com/testinprod-io/op-geth/pull/1 (command for exporting receipts uses custom RLP-encoding).
Import of >100 million OVM receipts, from genesis to Bedrock, completes in 30 minutes.
./op-reth import-receipts-op <exported-receipts>
3. Import State
Imports a .jsonl state dump. The block at which the state dump is made, must be the latest block in
reth's database. This should be block 105 235 063, the first Bedrock block (see step 1).
Import of >4 million OP mainnet accounts at Bedrock, completes in 10 minutes.
./op-reth init-state --chain optimism <state-dump>
