Shamirs still requires having the (single) private key present for signing.
Multisig is far superior for Bitcoin security. The keys can remain geographically separate at all times. Each signing operation requires only the partially signed transaction (PSBT) and the other public keys.
- lrvick 4y agoNon-issue if you only use the key once, then do a new split each time. Plenty of tooling exists to make this easily in reach with a simple shell script.
- thinkmassive 4y agoWhy would you use Shamirs when the Bitcoin protocol has a superior mechanism built in? SSS is a good solution for other key material, and for storing a paper key to be used for recovery purposes, but it's completely inferior to multisig for normal management of a shared and/or large Bitcoin wallet.
- lrvick 4y agoWell, bitcoin is not the only type of secret one needs to protect. GPG keys, other cryptoassets, password manager master encryption keys, etc etc. I like to have one solution that can work for my entire cryptographic life.
