I need to digest everything I possibly can about multisig. Help me out.

I HAVE MY REASONS.

1000 sats (plus more if i/stackers feel like it) to the best links/books/podcasts/guides/developments//etc shared here.

The latest, the greatest, the fundamentals, the technicals. I know stackers have the creme of the content crop..Lemme see it. I don't want any google serp bs.

Hopefully this can also serve as a good multisig repository for others interested.

Particularly interested in BTC insurance, collaborative custody. What's going on over there?

Rob Hamilton from Anchor Watch was on TFTC recently.

He maintains this google doc that's got great links to a ton of miniscript educational materials.

IMO - miniscript is absolutely massive for the collaborative custody & insurance use cases.

Most important thing is that you need the master pubkey (also called extended public key) of every cosigner.

So 2of3 only means you need 2 of 3 keys for signing (which are derived from the seed words). But you still need to know all master pubkeys.

There are three different formats so far: xpub, ypub and zpub. They generate addresses in different formats.

But afaik, xpub is enough and can be converted into the other formats. At least Sparrow wallet was able to.

While setting up my own multisig cold storage wallet, I created a LaTeX template.

Appreciate it. For some reason your link is giving a 404 though!

Yes, was missing a few letters at the end. I updated it :)

I find this to be a good primer on multisig, as it has guides on how to use multisig with Coldcard and Seed Signer https://bitcoiner.guide/multisig/
