Question about Bitkey's recovery process: They claim it's a standard 2 of 3 multisig. However, their recovery method seems unconventional. Bitkey allows users to restore their multisig setup even if 2 out of 3 keys are lost by contacting Bitkey for the server key. Does the server key store more than just 1 of 3 private keys? Wouldn't this key need to store the entire multisig data (something like output descriptors)? Script type, derivation path, and private keys for ALL other keys? How else could it recreate the multisig?
