Finally, by adding a subscription field to the base transaction included by block miners, mining in SMART can be restricted in a similar way. As discussed in the next section, this is crucial to avoid the minority rule on a private blockchain. In, MUSIC all privileges are granted and revoked using network transactions containing special metadata. The miner of the first "genesis" block automatically receives all privileges, including administrator rights to manage the privileges of other users. This administrator grants privileges to other users in transactions whose outputs contain the addresses of those users along with metadata that denotes the privileges conferred.
When changing the administration and mining privileges of other users, an additional and introduced restriction, in which a minimum proportion of existing administrators must vote to make a change. These votes are recorded by each administrator in a separate transaction, with the change applied when a sufficient consensus is reached. The first blocks of a chain define a "configuration phase", in which a single administrator can work around this voting process.
