A bitcoin p2p client

Run

# First start the node:
docker-compose up -d
# Then start the client:
cargo run

If you want to trigger some events on the nodes to be caught by the client:

# Create wallet
docker-compose exec btcliked bitcoin-cli -regtest -rpcuser=user -rpcpassword=pass createwallet toto
# Generate an address
ADDRESS=$(docker-compose exec btcliked bitcoin-cli -regtest -rpcuser=user -rpcpassword=pass -rpcwallet=toto getnewaddress) && echo $ADDRESS
# Mine 1 block to this address 
docker-compose exec btcliked bitcoin-cli -regtest -rpcuser=user -rpcpassword=pass -rpcwallet=toto generatetoaddress 1 $ADDRESS
