Multisignature
In short: An authorization arrangement requiring a specified threshold of signatures.
An authorization arrangement requiring a specified threshold of signatures. It is a technical control, not a guarantee about the people holding keys. For example, a design can require a threshold of participating keys rather than one signature. The specific threshold and recovery arrangement matter. Losing access to signers or misunderstanding their authority can affect funds access, so the name alone does not describe the whole control model.
