Multi signature, or multisig, is a security feature used to enhance the safety of cryptocurrency transactions. It requires multiple private keys to authorize a transaction, rather than relying on a single key. In a typical setup, a wallet can have several participating keys. For example, a 2-of-3 multisig wallet means that out of three different keys, at least two must sign off to complete a transaction. This setup is useful for organizations or shared accounts, adding a layer of protection against unauthorized access.Multisig wallets help mitigate risks associated with lost or stolen keys. If one key is compromised, the assets remain safe as the other keys are still required for any transaction. This method also facilitates more secure collaboration among users, preventing any single person from having full control over the assets.Overall, multisig enhances security and trust in handling cryptocurrency, making transactions more resilient against fraud and managing shared funds more efficiently.
