This page contains download links for data directories and node snapshots that can be used to more easily run your own node. Data directories and node snapshots are not required but can significantly simplify the node operation process.
This page focuses on data directories for op-erigon, not op-geth. Please refer here for op-geth. Also, please be aware that this page is not related with erigon-snapshots, which is an erigon specific feature.
OP Mainnet underwent a large database migration as part of the Bedrock Upgrade in 2023. Node operators must have a migrated OP Mainnet database to run a node. Migrated OP Mainnet databases can be generated manually or pre-migrated databases can be downloaded from the links on this page.
Always verify snapshots by comparing the sha256sum of the downloaded file to the sha256sum listed on this page. Check the sha256sum of the downloaded file by running
sha256sum <filename>in a terminal.
Using aria2 to download snapshots can significantly speed up the download process.
Snapshot is distributed in the compressed form using zstd compression. These snapshots are intended to be updated biweekly. The decompression result will be a single file named mdbx.dat. Make sure you have available space more than 1.5 TB. Current compression setting has a compression ratio about 25%. You must reconstruct the folder structure of erigon datadir which has the form:
<your_erigon_datadir>
└── chaindata
└── mdbx.dat
Example command:
# Assume you downloaded `op-mainnet-db-115313408.zst`
# We want to create datadir named `my-datadir`
# check sha256sum
sha256sum op-mainnet-db-115313408.zst
# decompress first
zstd --decompress op-mainnet-db-115313408.zst -o mdbx.dat
# create datadir structure
mkdir -p my-datadir/chaindata
# move mdbx file to chaindata dir
mv mdbx.dat my-datadir/chaindata
# run erigon with following command
./erigon --datadir=./my-datadir ...
