Vaults
Vaults run on a node and are akin to the concept of wallets in bitcoin. As the transactions are not globally broadcasted, each node will have only that part of data in their vaults that is considered relevant to them. Vaults store their data in a standard relational database and as such can be queried by using standard SQL. Vaults can contain both on ledger and off ledger data, meaning that it can also have some part of data that is not on ledger.
