Multisig is a technology designed to enhance security and is gaining attention as a cutting-edge Bitcoin technology. In
Bitcoin transactions, a signature based on a private key is applied to the receiving address to verify that the transfer is a legitimate transaction by the true owner. However, to send Bitcoin to an address using multisig, a single signature is insufficient; multiple signatures are required, and the number of required signatures is expressed as a fraction, such as 2/3.
This fraction indicates that signatures from two of the three pre-generated private keys are required. By
utilizing the multisig mechanism, you can create a wallet with enhanced security that prevents the unauthorized use of Bitcoin.
Even if one of the private keys is compromised or the wallet is hacked, Bitcoin cannot be sent unless the other private keys are known. Since the
private keys used for signing are managed on separate platforms, it is extremely difficult to launch a double attack against both platforms simultaneously. Furthermore
, if the master key is stored in a secure location not connected to the network, it can be used in the event that a private key is lost or compromised.
