Bitcoin Header Node (BHN) is a lightweight Bitcoin node that syncs and persists Bitcoin block headers. Developers can now verify Chainpoint proofs without needing a full Bitcoin node or a third-party API provider. BHN runs locally, syncs in an hour, and uses just 30MB of disk space. It’s written in Javascript and built with bcoin. Today, we’re releasing a beta version of BHN and looking for developer feedback.
