nice👍🤙

I believe IIRC it's mini script using a Taproot address that activates a threshold decay for a multisig. Something to the effect of:

If( Block = current block + x & No new txn)

Then( valid signatures = quorum -1)

I'm obviously not a coder but that's the gist of the function.

We recorded a brief presentation from them at the end of day 2 of the expo. You can watch it on X via Bitcoin magazine. It will also be released on YouTube in a couple of weeks.

Liana uses advanced Bitcoin features to make your wallet safer and offer recovery options. It works with on-chain timelocks, so backup keys can activate after a certain period of inactivity—when you stop making transactions. You can set up two sets of keys (or more). The first set, called the Primary Key(s), the one you use regularly. After a set period of no activity (chosen during setup), a second set of keys, called the "Recovery keys”, becomes active and can recover your funds. You can have multiple sets of recovery keys. This way, you stay in full control of your Bitcoin, with built-in safety features like backups and inheritance options.
