What is a transaction approver quorum?

Business accounts can set a rule that a team must approve outgoing transactions.

Transaction approver quorums are optional and only available to business accounts with at least two members. An approval team must authorize outgoing transactions before you can sign them with your keys.

The account owner can customize the quorum parameters depending on the number of members with approval permission. Take, for example, a business with a 3-of-5 transaction approver quorum. There are five roles with approver authority, and an outgoing transaction requires authorization from any three of them.
