Shamir Secret Sharing (SSS)
Shamir Secret Sharing is a cryptographic method for splitting a secret into multiple shares so only a chosen threshold can reconstruct it.
✦ Key Insight
It can reduce the risk of losing one backup while avoiding reliance on one complete copy.
✕ Common Misconceptions
Do not confuse secret sharing with multisig or threshold signing; reconstruction can recreate the full secret.

Private Key
A private key is a secret cryptographic code that proves ownership of crypto assets and allows the holder to authorize transactions.
Multisig Wallet
A multisig (multi-signature) wallet is a smart-contract or script-based wallet that requires multiple independent signatures to authorize a transaction — for example, 2-of-3 or 3-of-5 — instead of a single private key.
Seed Phrase
A seed phrase is a set of words that acts as the master backup for a crypto wallet.
Threshold Signature Scheme (TSS)
A Threshold Signature Scheme lets a defined threshold of participants cooperate to create one valid digital signature.
Wallet Backup
A wallet backup is recovery material or data kept so access can be restored after device loss, failure, or software removal.
