Multi-signature Bitcoin wallets come with the perk of enabling two or more people to sign a Bitcoin transaction before it is sent. As such, in case of a theft, it would be difficult to move such funds without the approval of a cosigner. Therefore, this brings a need to know how to create a shared Bitcoin wallet.
A Bitcoin wallet holds the private key that is used to sign funds by a user. The user will have to manually enter their private key to load the contents of their block or use a wallet that has already loaded the private key. As such, if the key is stolen or the wallet is hacked, the attacker will be able to move virtual funds on the blockchain. Either of these can be prevented if more than one user grants approval and this means, with the use of more than one private key.
