M-of-N Logic

M-of-N logic is the fundamental mathematical structure of multi-signature wallets, where M is the number of required signatures to authorize a transfer and N is the total number of available keys. This logic provides flexibility in security design; for example, a 2-of-3 setup allows for the loss of one key without losing access to funds, while still requiring a majority to move them.

It introduces a decentralized governance model where multiple parties must agree on an action before it is executed. This logic is used in corporate treasuries to prevent internal fraud by requiring multiple authorized signers.

It also allows for sophisticated inheritance planning or distributed security models. By adjusting M and N, users can balance convenience and security according to their specific needs.

It is a robust mechanism for controlling high-value assets in a programmable way.
