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:
| Node | RPC port * | P2P port * | RPC Username | RPC Password |
|---|---|---|---|---|
| node1 | 18332 | 18333 | bitcoin | bitcoin |
| node2 | 18502 | 18501 | bitcoin | bitcoin |
| node3 | 18602 | 18601 | bitcoin | bitcoin |
* Port as exposed on the host running docker.
./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.

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