# Zones and the trust model A zone is a private blockchain that only you can see inside. You run it, you read every transaction in it like a bank reads its core ledger, and the outside world sees nothing but money entering and leaving. The part that makes it more than a private database: everything in it is provable on a public chain, so you get a bank's privacy with a blockchain's guarantees.  You are the single sequencer. You order the transactions and produce the blocks, which is why you see everything and no one else sees anything beyond the boundary. That sounds like a lot of trust, and it is exactly the trust a bank customer already places in their bank: to keep the ledger honest and keep their data private. The difference from a bank is what you cannot do. You cannot invent a balance, fake a withdrawal, or break the backing, because every batch your zone settles is checked by a proof on the public chain. Your power is to see and to order. It is not to inflate or to steal. The canonical assets are locked on the host chain and only a valid proof releases them. :::note Earlier privacy systems tried to hide everything from everyone, including the operator. A bank cannot run that way: it has to see its own customers, and a regulator has to be able to compel disclosure. Kakushi's model is the one regulated finance already uses. The institution sees all, the customer sees their own, the public sees nothing. :::
