As you know, I’m in favor of offline seed *generation*. However this is offline *computation*.

I advise against seed splitting using Shamir’s secret sharing or spinoffs like Codex32. CoinKite’s seed XOR also falls into this category. These schemes bring all the seed material together at the same place and time.

This is an unnecessary security risk. Anyone who gets the combined seed after reassembly can spend all coins in the wallet, forever.

Genuine multisig is a superior solution. With multisig, the keys don’t have to come together. You can get each signature at each location separately, eliminating the single point of failure. #Bitcoin nostr:note1m6x7lan27tntu9tzk4aj4njvgd0chja835de07save9pjr7wnxusywnwh2
