Hash Vault is the city's exchange and holding service for gold and silver. Customers can buy metal, exchange it or leave it there under an agreement for safekeeping. The business also recovers and studies blockchain archives. Those records may identify old properties, companies and people, but reading a local copy doesn't mean the global network is working again.
An exchange depends on the weight and material being traded and a price both parties accept. A deposit needs a clear agreement about what Hash Vault is holding and for whom. The business doesn't need to issue a new currency to provide those services.
Archive work is a separate operation. Recovered computers may contain ledger copies, identity files and records referring to assets elsewhere. Staff preserve what they can read and compare it with other evidence. An old ownership entry may be useful without settling who can use the property now. A record can also give a family a place to search without proving that the person they remember survived.
