Multisig 101
Posted onMultisig, short for “multisignature,” is a cryptographic mechanism that requires multiple signatures to authorize and execute a transaction. What is Multisig Multisig ensures that multiple parties must collaborate and approve a transaction before it can be deemed valid. It provides an additional layer of security requiring multiple parties’ signatures to spend or transfer the crypto
