Bitcoin + MATT Docker Container

This repository contains a Dockerfile to build and run a custom version of Bitcoin, based on the branch matt from the repository https://github.com/Merkleize/bitcoin.

It contains the same opcodes as the bitcoin-inquisition repo, plus the following opcodes on taproot:

• OP_CHECKCONTRACTVERIFY
• OP_CAT
• OP_CHECKSIGFROMSTACK
• OP_INTERNALKEY

See merkle.fun for more information.

Features

• Lightweight image based on Ubuntu 20.04.
• Compiled with wallet support (no legacy wallet), and no GUI
• Exposes ports 18443 and 18444.
• Uses a custom bitcoin.conf file.

Build the Docker Image

docker build -t bitcoin_matt .

Pull from Docker hub

docker pull bigspider/bitcoin_matt

Run the Docker Container

docker run -d -p 18443:18443 bigspider/bitcoin_matt

Exposing port 18443 allows interacting with it using bitcoin-cli -regtest as normal, as long as a recent version of bitcoin-cli is in the path.

Alternatively, once the container is running, one can access a terminal in it with:

docker exec -it <container_id> /bin/bash

or run a command directly, for example:

docker exec <container_id> bitcoin-cli -regtest getblockcount

Configuration

A custom bitcoin.conf is copied to /root/.bitcoin/bitcoin.conf within the container.

The rpc user/pass are rpcuser and rpcpass, and some settings to enable mining transactions with zero fee are added for simplicity.

Contributions

If you'd like to contribute or make changes to this Docker image, feel free to open a pull request or raise an issue in this repository.

Disclaimer

Only use on regtest!
