A short demo of neutrino support in bcoin ⚡ 🎉

Prerequisites

In order to test our neutrino node, we need to mine a few test-coins we can send. For that we need the primary wallet address of our fullnode.

By default bcoin stores it's configuration in ~/.bcoin (/root/.bcoin inside the container). We want this configuration to stay consisten between container restarts, so we mount it to a temporary path on our local filesystem (/tmp/bcoin).

docker run --rm -v /tmp/bcoin:/root/.bcoin --name bcoin -d asbjornenge/bcoin:neutrino ./bin/bcoin --network=simnet
