In the context of cryptocurrencies, “multisig” refers to “multisignature,” a type of digital signature scheme that requires multiple keys to authorize a transaction, providing additional security.
Multisig can be used to create a digital equivalent of a joint bank account, where more than one person’s signature is needed to make a transaction. The idea is that if a single private key is compromised, it wouldn’t be sufficient to spend the funds associated with the multisig wallet.
For example, a 2-of-3 multisig wallet would require at least two out of three associated private keys to sign a transaction. This setup is useful for both personal use (for example, if you want to store backup keys in different locations) and for organizations (for example, to prevent any single person from having control over the funds).
By requiring multiple signatures, multisig technology helps to prevent theft, embezzlement, and any other unapproved transactions. It’s a significant innovation in the crypto space, improving security and enabling the creation of more complex ownership and control schemes for digital assets.
