Smart Contract Exchange in Databases for Trust-Independent Transactions

The patent introduces a hybrid architecture where a service provider-controlled cloud platform acts as an intermediary between users and the public trust ledger. The cloud platform provides computational services and application logic, while the public trust ledger provides immutable transaction recording and verification. This separation allows the service provider to maintain control over service delivery while the ledger ensures trust independence through cryptographic verification and distributed consensus, resolving the contradiction between platform capability and trust independence.

The patent merges the strengths of two distinct systems: the public trust ledger provides trust independence through cryptographic security and immutable recording, while the cloud computing platform provides adaptability through scalable computational resources and application services. The hybrid architecture allows complex operations to be executed on the cloud platform with results anchored to the trust ledger, combining operational versatility with trust independence.

The patent segments the system into distinct functional layers: the cloud database system handles operational data storage and application logic, while the public trust ledger handles immutable transaction recording and verification. This segmentation allows each component to specialize in its strength without requiring complete integration, maintaining data integrity through selective anchoring of critical transactions to the ledger while avoiding the complexity of fully merging the systems.
