Conclusion

Thank you for exploring the Cashu Book of NUTs. I hope grouping the specs by theme made Chaumian ecash a little easier to hold in your head.

Cashu is still moving. New NUTs will show up, old ones will get sharper, and wallets and mints will keep choosing which optional pieces to ship. If you want to help, the conversation and the spec text live in cashubtc/nuts.

Once again, all the credit for the protocol belongs to the original NUT authors and the people implementing them. This compilation is only a reading order.

Here’s to private, bearer bitcoin. Don’t spend it all in one place.
