SLIP-39 (Shamir Backup Standard)
A standard splitting wallet secrets into Shamir shares — addressing backup fragility but still requiring reconstruction that CLAVI's threshold signing eliminates.
Definition
Satoshi Labs Improvement Proposal 39, a standard for splitting a wallet's master secret into multiple mnemonic shares using Shamir's Secret Sharing. Unlike BIP-39's single seed phrase, SLIP-39 distributes the secret across N shares of which any K are required for reconstruction. Each share is encoded as a sequence of 20 or 33 words. SLIP-39 addresses the single-point-of-failure problem at the backup level, but reconstruction still requires assembling shares in a single location — a vulnerability that CLAVI's threshold signing eliminates by never reconstituting the full key at all.
