This repository allows you run a full bitcoin network in an isolated environment. It uses bitcoin SV's regtest capability to setup an isolated bitcoin network, and then uses docker to setup a network with 2 nodes.

This is useful because normally in regtest mode you would generate all coins in the same wallet as where you'd send the coins. With this setup, you can use one node to generate the coins and then send it to one of the other nodes, which can then again send it to another node to simulate more real-life bitcoin usage.

Simple run

docker-compose up

to start all the containers. This will start the bitcoin nodes, and expose RPC on all of them. The nodes will run on the following ports:

* Port as exposed on the host running docker.

./connect.sh

or, manually:

./regtest1.sh addnode "node2:18333" add
./regtest1.sh addnode "node3:18333" add

Note these samples use curl to exercise the API, but this would usually be bitcoin-cli. We're using curl so we don't have a dependency on bitcoin in the host.

You can also use the b.sh script passing any parameters. b.sh makes a call to the bitcoin-cli on regtest_node1_1

eg ./b.sh getinfo

Checks that the initial block count is 0.

# docker-compose up -d
Creating regtest_node1_1 ... done
Creating regtest_node2_1 ... done
Creating regtest_node3_1 ... done
# curl -d '{"jsonrpc":"2.0","id":"1","method":"getblockcount"}' -u bitcoin:bitcoin localhost:18332
{"result":0,"error":null,"id":"1"}

Check the "miner" node is connected to other nodes.

# curl -d '{"jsonrpc":"2.0","id":"1","method":"getpeerinfo","params":[]}' -u bitcoin:bitcoin -s localhost:18332 | jq '.result[] | {addr, inbound} '
