**Notes**:
1. Output values returned by Dogecoin API had precision loss in the clients prior to version 1.14.
It's caused by this issue https://github.com/dogecoin/dogecoin/issues/1558
The explorers that used older versions to export the data may show incorrect address balances and transaction amounts.
1. For Zcash, `vjoinsplit` and `valueBalance` fields are converted to inputs and outputs with type 'shielded'
https://zcash-rpc.github.io/getrawtransaction.html, https://zcash.readthedocs.io/en/latest/rtd_pages/zips/zip-0243.html
## Exporting the Blockchain
1. Install python 3.5.3+ https://www.python.org/downloads/
1. Install Bitcoin node https://hackernoon.com/a-complete-beginners-guide-to-installing-a-bitcoin-full-node-on-linux-2018-edition-cb8e384479ea
1. Start Bitcoin.
Make sure it downloaded the blocks that you need by executing `$ bitcoin-cli getblockchaininfo` in the terminal.
You can export blocks below `blocks`, there is no need to wait until the full sync
1. Install Bitcoin ETL:
```bash
> pip install bitcoin-etl
```
1. Export blocks & transactions:
```bash
> bitcoinetl export_all --start 0 --end 499999 \
--partition-batch-size 100 \
--provider-uri http://user:pass@localhost:8332 --chain bitcoin
```
The result will be in the `output` subdirectory, partitioned in Hive style:
```bash
output/blocks/start_block=00000000/end_block=00000099/blocks_00000000_00000099.csv
output/blocks/start_block=00000100/end_block=00000199/blocks_00000100_=00000199.csv
...
output/transactions/start_block=00000000/end_block=00000099/transactions_00000000_00000099.csv
...
```
In case `bitcoinetl` command is not available in PATH, use `python -m bitcoinetl` instead.
### Running in Docker
1. Install Docker https://docs.docker.com/install/
1. Build a docker image
```bash
> docker build --platform linux/x86_64 -t bitcoin-etl:latest .
> docker image ls
```
1. Run a container out of the image
```bash
> docker run --platform linux/x86_64 -v $HOME/output:/bitcoin-etl/output bitcoin-etl:latest export_blocks_and_transactions --start-block 0 --end-block 500000 \
--provider-uri http://user:pass@localhost:8332 --blocks-output output/blocks.json --transactions-output output/transactions.json
```
1. Run streaming to console or Pub/Sub
```bash
> docker build --platform linux/x86_64 -t bitcoin-etl:latest-streaming -f Dockerfile_with_streaming .
> echo "Stream to console"
> docker run --platform linux/x86_64 bitcoin-etl:latest-streaming stream -p http://user:pass@localhost:8332 --start-block 500000
> echo "Stream to Pub/Sub"
> docker run --platform linux/x86_64 -v /path_to_credentials_file/:/bitcoin-etl/ --env GOOGLE_APPLICATION_CREDENTIALS=/bitcoin-etl/credentials_file.json bitcoin-etl:latest-streaming stream -p http://user:pass@localhost:8332 --start-block 500000 --output projects/your-project/topics/crypto_bitcoin
```
1. Refer to https://github.com/blockchain-etl/bitcoin-etl-streaming for deploying the streaming app to
Google Kubernetes Engine.
### Command Reference
- [export_blocks_and_transactions](#export_blocks_and_transactions)
- [enrich_transactions](#enrich_transactions)
- [get_block_range_for_date](#get_block_range_for_date)
- [export_all](#export_all)
- [stream](#stream)
All the commands accept `-h` parameter for help, e.g.:
```bash
> bitcoinetl export_blocks_and_transactions --help
Usage: bitcoinetl.py export_blocks_and_transactions [OPTIONS]
Export blocks and transactions.
Options:
-s, --start-block INTEGER Start block
-e, --end-block INTEGER End block [required]
-b, --batch-size INTEGER The number of blocks to export at a time.
-p, --provider-uri TEXT The URI of the remote Bitcoin node
-w, --max-workers INTEGER The maximum number of workers.
--blocks-output TEXT The output file for blocks. If not provided
blocks will not be exported. Use "-" for stdout
--transactions-output TEXT The output file for transactions. If not
provided transactions will not be exported. Use
"-" for stdout
--help Show this message and exit.
```
For the `--output` parameters the supported type is json. The format type is inferred from the output file name.
#### export_blocks_and_transactions
```bash
> bitcoinetl export_blocks_and_transactions --start-block 0 --end-block 500000 \
--provider-uri http://user:pass@localhost:8332 \
--blocks-output blocks.json --transactions-output transactions.json
```
Omit `--blocks-output` or `--transactions-output` options if you want to export only transactions/blocks.
You can tune `--batch-size`, `--max-workers` for performance.
Note that `required_signatures`, `type`, `addresses`, and `value` fields will be empty in transactions inputs.
Use [enrich_transactions](#enrich_transactions) to populate those fields.
#### enrich_transactions
You need to run bitcoin daemon with option `txindex=1` for this command to work.
```bash
> bitcoinetl enrich_transactions \
--provider-uri http://user:pass@localhost:8332 \
--transactions-input transactions.json --transactions-output enriched_transactions.json
```
You can tune `--batch-size`, `--max-workers` for performance.
#### get_block_range_for_date
```bash
> bitcoinetl get_block_range_for_date --provider-uri http://user:pass@localhost:8332 --date=2017-03-01
```
This command is guaranteed to return the block range that covers all blocks with `block.time` on the specified
date. However the returned block range may also contain blocks outside the specified date, because block times are not
monotonic https://twitter.com/EvgeMedvedev/status/1073844856009576448. You can filter
`blocks.json`/`transactions.json` with the below command:
```bash
> bitcoinetl filter_items -i blocks.json -o blocks_filtered.json \
-p "datetime.datetime.fromtimestamp(item['timestamp']).astimezone(datetime.timezone.utc).strftime('%Y-%m-%d') == '2017-03-01'"
```
#### export_all
```bash
> bitcoinetl export_all --provider-uri http://user:pass@localhost:8332 --start 2018-01-01 --end 2018-01-02
```
You can tune `--export-batch-size`, `--max-workers` for performance.
#### stream
```bash
> bitcoinetl stream --provider-uri http://user:pass@localhost:8332 --start-block 500000
```
- This command outputs blocks and transactions to the console by default.
- Use `--output` option to specify the Google Pub/Sub topic where to publish blockchain data,
e.g. `projects/your-project/topics/crypto_bitcoin`. Blocks and transactions will be pushed to
`projects/your-project/topics/crypto_bitcoin.blocks` and `projects/your-project/topics/crypto_bitcoin.transactions`
topics.
- The command saves its state to `last_synced_block.txt` file where the last synced block number is saved periodically.
- Specify either `--start-block` or `--last-synced-block-file` option. `--last-synced-block-file` should point to the
file where the block number, from which to start streaming the blockchain data, is saved.
- Use the `--lag` option to specify how many blocks to lag behind the head of the blockchain. It's the simplest way to
handle chain reorganizations - they are less likely the further a block from the head.
- Use the `--chain` option to specify the type of the chain, e.g. `bitcoin`, `litecoin`, `dash`, `zcash`, etc.
- You can tune `--period-seconds`, `--batch-size`, `--max-workers` for performance.
