Multiple signatures are a sort of digital signature that allows more than two people to sign something together.

In the context of cryptocurrencies, multi-signature technology was initially utilized for Bitcoin addresses in 2012. Multi-signatures are commonly utilized in sectors with security concerns.

A multi-signature address can specify the number of keys it requires: the most popular is two-thirds (2/3), which means that just two initial signatures are required to access funds in a three-signature address. In fact, there are numerous different varieties, such as 3/3 (three-fourths), 3/4 (three-quarters), and so on.
