BCoin is a bitcoin client which implements BIP-37. It can track transactions, public keys, and public key hashes (bitcoin addresses) without saving the entire blockchain to disk. This means you can have a wallet with a synchronized balance and send and receive payments without keeping track of a 20GB database. BCoin is implemented in pure javascript, and is browserify-able (this means compiling a binding to an ECDSA library is not even required for node.js). For us, the fact that peer to peer communication is not encrypted on the Bitcoin network seems like more of an oversight to me than anything else. They now have begun integrating the Lightning Network. It's called "blight". Purse.io takes over this episode as both Christopher Jeffrey (JJ) who is the CTO & Engineer at Purse and podcast regular Steven McKie join us in the studio. We continue to give you that mid-week goodness.
