What is multi-signature?

 

Standard transactions on cryptocurrency networks are referred to as single-signature transactions because it takes only one digital signature for a standard transaction to be completed. However, with multi-signature, each permission corresponds to multiple private keys, and the weight of the transaction signature must reach the customized weight threshold before the transaction can be executed.

 

The TRON multi-signature scheme includes three kinds of permission: owner-permission, witness-permission, and active-permission, where owner-permission has the authority to execute all contracts, witness-permission is used for generating SR's blocks, and active-permission is customized permission (a combination of contracts permission sets). There can be only one owner permission group and at most eight active permission groups for each address. Witness permission is accessible to only SRs.

 

After creating a multi-signature permission group, users can add addresses to this group. They can set up weights for each address and threshold value for the weight of this permission group. When signing a transaction in a permission group, if the signature weights of the added address reach the threshold value, the transaction can be executed.

 

In other words, the multi-signature mechanism allows multiple people to co-manage assets, with their signatures of different weights. In this way, users can better secure their assets by setting up multiple permission groups to accommodate various scenarios.
