Cash |
class Cash : OnLedgerAsset<Currency, Commands, State> A cash transaction may split and merge money represented by a set of (issuer, depositRef) pairs, across multiple input and output states. Imagine a Bitcoin transaction but in which all UTXOs had a colour (a blend of issuer+depositRef) and you couldnt merge outputs of two colours together, but you COULD put them in the same transaction. |
CommodityContract |
class CommodityContract : OnLedgerAsset<Commodity, Commands, State> A commodity contract represents an amount of some commodity, tracked on a distributed ledger. The design of this contract is intentionally similar to the Cash contract, and the same commands (issue, move, exit) apply, the differences are in representation of the underlying commodity. Issuer in this context means the party who has the commodity, or is otherwise responsible for delivering the commodity on demand, and the deposit reference is use for internal accounting by the issuer (it might be, for example, a warehouse and/or location within a warehouse). |
Obligation |
class Obligation<P> : Contract An obligation contract commits the obligor to delivering a specified amount of a fungible asset (for example the Cash contract) at a specified future point in time. Settlement transactions may split and merge contracts across multiple input and output states. The goal of this design is to handle amounts owed, and these contracts are expected to be netted/merged, with settlement only for any remainder amount. |
OnLedgerAsset |
abstract class OnLedgerAsset<T : Any, C : CommandData, S : FungibleAsset<T>> : Contract An asset transaction may split and merge assets represented by a set of (issuer, depositRef) pairs, across multiple input and output states. Imagine a Bitcoin transaction but in which all UTXOs had a colour (a blend of issuer+depositRef) and you couldnt merge outputs of two colours together, but you COULD put them in the same transaction. |
