May topics about austinbitdevs.com HOT 38 CLOSED

Two things I made this month:

• Bitcoin Chess: https://github.com/supertestnet/bitcoin-chess (uses key tweaking to hide chess moves in bitcoin pubkeys, meant to teach devs how key tweaking works)

• Vanilla JS browser wallet: https://github.com/supertestnet/vanilla-js-browser-wallet (a total of 642 lines of code including about 70 lines of css and 80 lines of html. I also used the following libraries which are not included in the code-line count: qrcode.js, bitcoin-js, bip39, bip32, and buffer. The purpose of the wallet is so that web devs can easily customize it and put a non-custodial web wallet on their website or in their chrome extension.)

This new lightning node in scala is also neat: https://github.com/fiatjaf/cliche

It is almost as bare bones of a lightning implementation as it is possible to get. It does not even require an external source of blockchain data because it has a built in electrum client for that. Fiatjaf is now using it as the backend for lntxbot and he positively raves about it.
