## Overview
|
|
|
|
|
`rosetta-bitcoin` provides a reference implementation of the Rosetta API for
|
|
|
|
|
Bitcoin in Golang. If you haven't heard of the Rosetta API, you can find more
|
|
|
|
|
information [here](https://rosetta-api.org).
|
|
|
|
|
|
|
|
|
|
## Features
|
|
|
|
|
* Rosetta API implementation (both Data API and Construction API)
|
|
|
|
|
* UTXO cache for all accounts (accessible using `/account/balance`)
|
|
|
|
|
* Stateless, offline, curve-based transaction construction from any SegWit-Bech32 Address
|
|
|
|
|
|
|
|
|
|
## Usage
|
|
|
|
|
As specified in the [Rosetta API Principles](https://www.rosetta-api.org/docs/automated_deployment.html),
|
|
|
|
|
all Rosetta implementations must be deployable via Docker and support running via either an
|
|
|
|
|
[`online` or `offline` mode](https://www.rosetta-api.org/docs/node_deployment.html#multiple-modes).
|
|
|
|
|
|
|
|
|
|
To build a Docker image from this repository, run the command `make build`. To start
|
|
|
|
|
`rosetta-bitcoin`, you can run:
|
|
|
|
|
* `make run-mainnet-online`
|
|
|
|
|
* `make run-mainnet-offline`
|
|
|
|
|
* `make run-testnet-online`
|
|
|
|
|
* `make run testnet-offline`
|
|
|
|
|
|
|
|
|
|
By default, running these commands will create a data directory at `<working directory>/bitcoin-data`
|
|
|
|
|
and start the `rosetta-bitcoin` server at port `8080`.
|
|
|
|
|
|
|
|
|
|
## System Requirements
|
|
|
|
|
`rosetta-bitcoin` has been tested on an [AWS c5.2xlarge instance](https://aws.amazon.com/ec2/instance-types/c5).
|
|
|
|
|
This instance type has 8 vCPU and 16 GB of RAM. If you use a computer with less than 16 GB of RAM,
|
|
|
|
|
it is possible that `rosetta-bitcoin` will exit with an OOM error.
|
|
|
|
|
|
|
|
|
|
### Recommended OS Settings
|
|
|
|
|
To increase the load `rosetta-bitcoin` can handle, it is recommended to tune your OS
|
|
|
|
|
settings to allow for more connections. On a linux-based OS, you can run the following
|
|
|
|
|
commands ([source](http://www.tweaked.io/guide/kernel)):
|
|
|
|
|
```text
|
|
|
|
|
sysctl -w net.ipv4.tcp_tw_reuse=1
|
|
|
|
|
sysctl -w net.core.rmem_max=16777216
|
|
|
|
|
sysctl -w net.core.wmem_max=16777216
|
|
|
|
|
sysctl -w net.ipv4.tcp_max_syn_backlog=10000
|
|
|
|
|
sysctl -w net.core.somaxconn=10000
|
|
|
|
|
sysctl -p (when done)
|
|
|
|
|
```

|
|
|
_We have not tested `rosetta-bitcoin` with `net.ipv4.tcp_tw_recycle` and do not recommend
|
|
|
|
|
enabling it._
|
|
|
|
|
|
2020-09-16 21:03:14 +02:00
|
|
|
You should also modify your open file settings to `100000`. This can be done on a linux-based OS
|
|
|
|
|
with the command: `ulimit -n 100000`.

|
## Architecture
|
|
|
|
|
`rosetta-bitcoin` uses the `syncer`, `storage`, `parser`, and `server` package
|
|
|
|
|
from [`rosetta-sdk-go`](https://github.com/coinbase/rosetta-sdk-go) instead
|
|
|
|
|
of a new Bitcoin-specific implementation of packages of similar functionality. Below
|
|
|
|
|
you can find a high-level overview of how everything fits together:

### Optimizations
|
|
|
|
|
* Automatically prune bitcoind while indexing blocks
|
|
|
|
|
* Reduce sync time with concurrent block indexing
|
|
|
|
|
* Use [Zstandard compression](https://github.com/facebook/zstd) to reduce the size of data stored on disk
|
|
|
|
|
without needing to write a manual byte-level encoding
|
|
|
|
|
|
|
|
|
|
#### Concurrent Block Syncing
|
|
|
|
|
To speed up indexing, `rosetta-bitcoin` uses concurrent block processing
|
|
|
|
|
with a "wait free" design (using channels instead of sleeps to signal
|
|
|
|
|
which threads are unblocked). This allows `rosetta-bitcoin` to fetch
|
|
|
|
|
multiple inputs from disk while it waits for inputs that appeared
|
|
|
|
|
in recently processed blocks to save to disk.

## Testing with rosetta-cli
|
|
|
|
|
To validate `rosetta-bitcoin`, [install `rosetta-cli`](https://github.com/coinbase/rosetta-cli#install)
|
|
|
|
|
and run one of the following commands:
|
|
|
|
|
* `rosetta-cli check:data --configuration-file rosetta-cli-conf/bitcoin_testnet.json`
|
|
|
|
|
* `rosetta-cli check:construction --configuration-file rosetta-cli-conf/bitcoin_testnet.json`
|
|
|
|
|
* `rosetta-cli check:data --configuration-file rosetta-cli-conf/bitcoin_mainnet.json`
|
|
|
|
|
* `rosetta-cli check:construction --configuration-file rosetta-cli-conf/bitcoin_mainnet.json`
|
|
|
|
|
|
|
|
|
|
## Future Work
|
|
|
|
|
* Publish benchamrks for sync speed, storage usage, and load testing
|
|
|
|
|
* Rosetta API `/mempool/*` implementation
|
|
|
|
|
* Add CI test using `rosetta-cli` to run on each PR (likely on a regtest network)
|
|
|
|
|
* Add performance mode to use unlimited RAM (implementation currently optimized to use <= 16 GB of RAM)
|
|
|
|
|
* Support Multi-Sig Sends
|
|
