What are Permissions

In Graphene-Based blockchains, each account is separated into several permissions, such as

Both can be defined in the Permissions tab of your account using so called authorities (see below) together with a so called threshold that has to be exceeded in order for a transaction to be valid.

Authorities

An authority consists of one or many entities that authorize an action, such as transfers or trades. They consist of one or several pairs of account names or public keys with each having a weight associated with it. In order to obtain a valid transaction, i.e. obtain sufficient authority, the sum of the weights from signing the parties has to exceed the threshold as defined in the permissions.
