What is a Multisig wallet?
Multisignature is a special type of digital signature that allows two, three, or more parties to sign documents/transactions together like a team. Therefore, a multisignature is created via a combo of several unique signatures. This advanced technology exists in the Crypto World, but this principle was known long before. Multisignature was used back in the ancient time when monks were given parts of the tomb key so no individual monk can enter the tomb with sacred remains to steal them.
If we speak about multisig tech nowadays, it was implemented to the BTC address in 2012 and the first wallet with multisig function was created in 2013.
So how does this technology work? Most cases when multisig wallets are in need are related to security issues. Its appliance gives users the chance to generate an additional safety performance for their assets. Access to funds kept on a multisig wallet is possible only when two or more signatures are provided simultaneously. On the basis of how the multisig wallet is created, there can be various signature combinations presented. You can typically meet the following one: 2 of 2 (when both of two signatures are compulsory to fulfill a transaction), 2 of 3 (when only 2 of 3 signatures is enough to spend funds), 3 of 3 and etc. The maximum available number is 15 of 15 signatures.
As well as different people holding the keys/signatures, it can also be one individual having keys on different devices (mobile, PC, tablet) – multi-factor authentication in other words. In this case, if one of your devices is stolen, the thief will not be able to access the multisig wallet and take your crypto.
There are multisignature wallets for different cryptocurrencies, but today we are going to evaluate the best Bitcoin wallets with multisig technology.
