A multisig wallet is a special type of wallet for securely storing your Bitcoin. 3-5 signatures are typically required to access the stored Bitcoin.<\/p>\n

<\/p>\n

What is a MultiSig wallet?<\/h2>\n

A multisig wallet is a wallet that provides users with extra security because it requires multiple unique signatures (hence multi-signature) to authorize and execute a transaction. A traditional \u2014 or single-sig \u2014 Bitcoin wallet contains a Bitcoin address, each with one associated private key that grants the keyholder complete control over the funds.<\/p>\n

With bitcoin multisignature addresses, you can have a Bitcoin address with three or more associated private keys, such that you need any two of them to spend the funds. A wallet\u2019s private key grants access to a user\u2019s funds. It proves ownership of your bitcoin and is necessary to execute transactions in combination with a public key. If a private key is lost, all funds are lost, and there is no way to recover them. Spreading access to a wallet across multiple keys is a safer measure.<\/p>\n

Multisig is not native to Bitcoin. The concept has been used in the banking sector for years and previous to that it had been used for thousands of years to protect the security of crypts holding the precious relics of saints. The superior of a monastery would give monks only partial keys for gaining access to the precious relics. Thus, no single monk could gain access to and possibly steal the relics.<\/p>\n

Single-key vs Multisig<\/h2>\n

Most Bitcoin wallets use a single signature setup. This type of setup only requires one signature to sign a transaction. Single-key addresses are easier to manage as access to funds is faster. Still, they also represent a single point of failure increasing risks for your security since hackers and malicious actors could more easily access them. <\/p>\n

\n <\/p>\n<\/figure>\n

Single-key wallets are good options for small and faster transactions \u2014 like face-to-face payments \u2014 but are not recommended for individuals and businesses who need to store considerable amounts of bitcoin. Like with cash, if you lose access to your single-key wallet, your funds are gone and there\u2019s nothing you can do to recover them.<\/p>\n

A multisig wallet, on the other hand, is configured in a way that requires a combination of keys from different sources to be operational \u2014 for example, 2-of-3, meaning that transactions can only be executed if at least 2 keys out of 3 are used. <\/p>\n

Different variations exist, with a combination of signatures required to access funds and execute transactions. Some solutions demand that all the private keys are used to create the signature and authorize a transaction for maximum security.<\/p>\n

Multisig solutions are not new to bitcoin. The concept was first pioneered and formalized into the standard Bitcoin protocol as early as 2012 but only started getting traction in 2014 after the shutdown of the Silk Road<\/a> and the collapse of the bitcoin exchange Mt.Gox<\/a>. The two adverse events urged developers to promote a better way to obtain maximum security against hacks and confiscation by authorities<\/a>. <\/p>\n

Why use a multisig wallet?<\/h2>\n

There is an increasing practice among businesses to store their bitcoin as a reserve asset in multisig wallets, as solely relying on one person to preserve the private key could turn out to be a regrettable mistake for the security of the funds. By using a multisig wallet, users can 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.<\/p>\n

Multiple signatures required<\/a> to authorize a transaction make it more difficult for someone to steal your bitcoin since they would need access to all of your private keys to get hold of your funds. <\/p>\n

Imagine any individual or business entity creating a 2-of-3 multisig address and storing each private key in a different physical place and device, like a mobile phone, a laptop and a tablet. If one of the locations is accessed by malicious actors, the device located there is stolen, and even if the wallet is compromised, the attackers won\u2019t be able to spend the funds using only that one key they found.<\/p>\n

In the same way, phishing and malware attacks are more easily prevented because the attackers can\u2019t do much with one single key at their disposal. <\/p>\n

Besides malicious attacks of any nature, users can still access their bitcoin using their other 2 keys if they lose their private key. Multisig wallets are indeed a passport to more peace of mind with your funds.<\/p>\n

How does a multisig wallet work?<\/h2>\n

The process to initiate a transaction with a multisig wallet follows the same steps regardless of the type of solution chosen. The user will input the transaction\u2019s details in the wallet and enter their private key to sign it. The transaction will be pending and only finalized \u2014 and the funds sent to the correct address \u2014 once all the required keys are submitted. <\/p>\n

Example: <\/p>\n

Step 1: Connect the hardware device to an existing wallet or create a new one;<\/p>\n

Step 2: Wait for the wallet to recognize the hardware device and sign;<\/p>\n

Connect a second hardware and proceed as above;<\/p>\n

Connect the third wallet and sign as with the previous devices.<\/p>\n

Step 3: To execute a transaction you will only need two of the 3 setup wallets above.<\/p>\n

There\u2019s no hierarchy in the private keys, only the number required to sign the transaction in no particular order matters. There is no expiration date in multisig transactions, which will remain pending until all the required keys are provided.<\/p>\n

Types of multi-signature wallets<\/h2>\n

Depending on the number of private keys and signatures required to authorize a transaction, different types of multisig wallets can serve the purpose, which are highlighted below.<\/p>\n
