Patent attributes
A method and system to securely split a digital promise that is recorded in a blockchain. A digital promise represents a promise by a promisor to pay a promisee an asset when a specified condition is satisfied. The specified condition may be fulfillment of a digital contract, also recorded in the blockchain, to which the digital promise is linked. When splitting a digital promise, a split transaction is recorded indicating a split into a first child digital promise and a second child digital promise. In each child digital promise, the promisor promises to pay a child promisee a portion of the asset when a specified child condition is satisfied. When a digital promise is split, the digital promise itself is no longer payable, but the child digital promises are payable when both the specified condition and the specified child condition for the child digital promise are satisfied.
