Why is Shamir sharding not doable on coldcards?
Discussion
As a layman, is that what the math trick that enabled the highly unpopular Ledger wotyemehcallit service?
Believe Keystone signer does this on BTC only firmware. Ben Perrin has some old vids about it before he exclusively shilled coinkite
They went with XOR. Any specific reason to choose shamir?
More shards.
We invented SeedXOR because SSS is complex, needs computers to recover and no adoption. if you want M of N just multisig.
Or use a passphrase if multisig doesn’t fit your needs and 2 of 2 does it for you. Offers similar security with a fat enough passphrase. (Agree or disagree, nostr:npub1az9xj85cmxv8e9j9y80lvqp97crsqdu2fpu3srwthd99qfu9qsgstam8y8 ?)
