What is multisignature wallet?

As a simple analogy, we can imagine a secure deposit box that has two locks and two keys.
One key is held by Alice and the other one is held by Bob.
The only way they can open the box is by providing their both keys at the same time, so one cannot open the box without the consent of the other.

Basically speaking, the funds stored on a multi-signature address can only be accessed by using 2 or more signatures.
Therefore, the use of a multisig wallet enables users to create an additional layer of security to their funds.

Use cases for a multisignature wallet

Increasing security

By using a multisig wallet, users are able to prevent the problems caused by the loss or theft of a private key. So even if one of the keys is compromised, the funds are still safe.

Imagine that Alice creates a 2-of-3 multisig address and then stores each private key into a different place or device (e.g. mobile phone, laptop, and tablet).
Even if her mobile device is stolen, the thief won’t be able to access her funds using only 1 of the 3 keys. Similarly, phishing attacks and malware infections are less likely to succeed because the hacker would most likely have access to a single device and key.

Malicious attacks aside, if Alice loses one of her private keys, she can still access her funds using the other 2 keys.

Two-factor authentication

By creating a multisig wallet that requires two keys, Alice is able to create a two-factor authentication mechanism to access her funds. For instance, she could have one private key stored in her laptop and the other one in her mobile device (or even on a piece of paper). This would ensure that only someone who has access to both keys is able to make a transaction.

Keep in mind, however, that using multisig technology as two-factor authentication can be dangerous – especially if it is set as a 2-of-2 multisig address. If one of the keys are lost, you won’t be able to access your funds.

Escrow transactions

Creating a 2-of-3 multisig wallet can allow for an escrow transaction between two parties (Alice and Bob) that includes a third party (Charlie) as a mutually trusted arbiter in case anything goes wrong.

Charlie, the arbiter, would only need to step in if there was a dispute, at which point he could use his key to create a signature that would be provided to either Alice or Bob, according to Charlie’s judgment.

Decision making

A board of directors might use a multisig wallet to control access to a company’s funds. For example, by setting up a 4-of-6 wallet where each board member holds one key, no individual board member is able to misuse the funds. Therefore, only decisions that are agreed upon by the majority can be executed.
