MultisignaturVerfahren

MultisignaturVerfahren, often shortened to multisig, refers to a type of digital signature scheme that requires more than one private key to authorize a transaction or validate a document. Instead of a single signature being sufficient, a predetermined number of signatures from a larger set of authorized signers must be present. This enhances security by distributing control and preventing a single point of failure. For example, a common configuration is a 2-of-3 multisig, meaning two out of three designated individuals must sign for the transaction to be valid.

The implementation of MultisignaturVerfahren is particularly prevalent in cryptocurrency transactions, where it can be used for secure management of funds. Businesses might employ multisig to ensure that no single employee can unilaterally move company assets. In personal finance, it can provide an extra layer of protection for digital wallets. The process typically involves generating a public key that is a combination of the individual public keys of the authorized signers. When a transaction is initiated, it is broadcast with a script that specifies the required number of signatures. Only when the correct number of valid signatures are provided can the transaction be confirmed and executed. This mechanism significantly reduces the risk of theft or unauthorized access.
