Shamir's Secret Sharing
A cryptographic method to split a secret into multiple shares so any threshold subset can reconstruct it.
- Also known as
- SSSSLIP-0039
Shamir's Secret Sharing splits a secret into multiple shares using threshold cryptography. In an M-of-N setup, any M shares can reconstruct the secret, while fewer than M shares reveal no useful information.
Some wallets use SLIP-0039, a standardized mnemonic format based on Shamir-style sharing. Shares still need careful storage, clear labeling, and tested recovery; confusing shares from different backups can make recovery fail.
