# `monero-blockchain-export` - Reference
|
|
|
|
!!! note
|
|
Nowadays, there is little usage for raw blockchain export / import. In the past the p2p blockchain download was much slower. Back than blockchain.raw file was used to speed up the process of bootstrapping a node.
|
|
|
|
## Overview
|
|
|
|
The tool dumps local blockchain to raw format, known as the `blockchain.raw` file.
|
|
|
|
This could be useful if you want to process blockchain efficiently with your custom tools,
|
|
as the raw format is probably easier to work with than Monero's custom lmdb database.
|
|
|
|
The tool works on your local copy of the blockchain. It does not require `monerod` running.
|
|
|
|
## Syntax
|
|
|
|
`./monero-blockchain-export [options]`
|
|
|
|
Example:
|
|
|
|
`./monero-blockchain-export --help`
|
|
|
|
## Running
|
|
|
|
Go to directory where you unpacked Monero.
|
|
|
|
`./monero-blockchain-export --stagenet --output-file=/tmp/blockchain.raw`
|
|
|
|
|
|
## Options
|
|
|
|
### Help
|
|
|
|
| Option | Description
|
|
|---------------------|--------------------------------------------------------------------------------------------------------------------------------------
|
|
| `--help` | Enlist available options.
|
|
|
|
### Pick network
|
|
|
|
| Option | Description
|
|
|---------------------|--------------------------------------------------------------------------------------------------------------------------------------
|
|
| (missing) | By default `monero-blockchain-export` assumes [mainnet](/infrastructure/networks#mainnet).
|
|
| `--stagenet` | Export [stagenet](/infrastructure/networks#stagenet) blockchain.
|
|
| `--testnet` | Export [testnet](/infrastructure/networks#testnet) blockchain.
|
|
|
|
### Logging
|
|
|
|
Specifying the log file path is not supported.
|
|
|
|
| Option | Description
|
|
|---------------------|--------------------------------------------------------------------------------------------------------------------------------------
|
|
| `--log-level` | `0-4` with `0` being minimal logging and `4` being full tracing. Defaults to `0`. These are general presets and do not directly map to severity levels. For example, even with minimal `0`, you may see some most important `INFO` entries. Example: <br />`./monero-blockchain-export --log-level=1`
|
|
|
|
### Input
|
|
|
|
| Option | Description
|
|
|----------------------------|--------------------------------------------------------------------------------------------------------------------------------------
|
|
| `--data-dir` | Full path to data directory. This is where the blockchain, log files, and p2p network memory are stored. For defaults and details see [data directory](/interacting/overview/#data-directory).
|
|
| `--database`, `--db-type` | The default and only valid value is `lmdb`.
|
|
|
|
### Output
|
|
|
|
| Option | Description
|
|
|---------------------|--------------------------------------------------------------------------------------------------------------------------------------
|
|
| `--output-file` | Specify output file path. The default is `$DATA_DIR/export/blockchain.raw`. Example: <br />`./monero-blockchain-export --output-file=/tmp/blockchain.raw`
|
|
| `--blocksdat` | Output in blocks.dat format.
|
|
| `--block-stop` | Only export up to this block number. By default do the full export (value `0`).
