Subscription to dependencies in smart contracts

摘要

The disclosed technology is generally directed to smart contract technology. In one example of the technology, responsive to a smart contract subscription request from a requestor to a first smart contract, a registry entry is added to a first smart contract registry such that the added registry entry includes requestor information associated with the requestor, and subscription information associated with at least one exposed interface of the first smart contract. Responsive to a change occurring that is associated with at least one exposed interface of the first smart contract, based on the registry, any subscribers to the first smart contract that have a subscription to which the change pertains are determined. Responsive to determining subscribers to the first smart contract that have a subscription to which the change pertains, the determined subscribers are caused to be notified of the change.
