Dependencies

​
Create an archive node

Blockscout needs access to an archive node for your OP Stack chain to properly index transactions, blocks, and internal interactions. If using op-geth, you can run a node in archive mode with the --gcmode=archive flag.
Archive nodes take up significantly more disk space than full nodes. You may need to have 2-4 terabytes of disk space available (ideally SSD) if you intend to run an archive node for a production OP Stack chain. 1-200 gigabytes of disk space may be sufficient for a development chain.
