blockchain_import

This imports blocks from `$MONERO_DATA_DIR/export/blockchain.raw` (exported using the

`monero-blockchain-export` tool as described above) into the current database.

Defaults: `--batch on`, `--batch size 20000`, `--verify on`

Batch size refers to number of blocks and can be adjusted for performance based on available RAM.

Verification should only be turned off if importing from a trusted blockchain.
