Honest question. When someone says the blockchain can be used for anything OTHER than financial transactions, for example - supply chain, health records, etc. what is the actual underlying data that will be stored on the blockchain?

When it comes to a quasi-banking or quasi-wallet system, I find it easy to visualize that the blockchain holds accounts with balances, and there are transactions which move money between accounts. Blockchain's decentralization and write-only properties help because no single entity can make your money disappear, and no entity can rollback a transaction.

What is going on with other use-cases of blockchain? What does a supply-chain system actually store on the blockchain? The SKU list? The price of SKUs? The stock level of each SKU in each warehouse? What?
