My name is Humberto, owner of the repository https://github.com/bitcoin-education/bitcoin-java.

I'm posting to divulge a new open-source Bitcoin library written in Java, with support for taproot single key transactions: https://github.com/bitcoin-education/bitcoin-java.

My main motivation to build this library was for educational purposes. Also, I was missing a lean bitcoin library written in Java, since I think bitcoinj too feature-heavy. I don't intend to include features that allow communication with nodes nor any online features in it. I think it is ideal for developers that want to build a wallet in Java.

Feedback, PRs, and issues are welcome and appreciated.

Website of the project, where I plan to post more examples using it: https://www.bitcoineducation.site/

Best regards,

Humberto
