0000 A system processes inter-program communication by merging application program interfaces (APIs). API metadata for a plurality of mergeable APIs is extracted from a distributed API repository. A generative artificial intelligence process that executes a deep-learning neural network generates API clusters of combinable APIs from the API metadata and, from telemetry, identifies an API solution cluster having a highest performance ranking. The combinable APIs of the API solution cluster are combined, consistent with an API security rule, into a constructed API. The constructed API is tested as a self-executing smart contract stored on a distributed ledger blockchain, and the operability test results are returned to the generative artificial intelligence process. The constructed API is deployed to the distributed ledger blockchain, obsolete APIs are removed from the distributed API repository, and the distributed ledger blockchain is monitored in real time to incorporate performance metrics into the generative artificial intelligence process.

A system and method may leverage Gen AI to prevent future digital transactions by fraudulent actors using digital avatars of an expired entity. A proof of death may be generated for an expired entity, such as a deceased person, and recorded on the blockchain. An avatar associated with the expired entity may control digital assets or rights associated with the avatar. The avatar of the expired entity may be caused to expire to prevent future use by generating an electronic proof of expiry of the avatar that is recorded in a blockchain ledger or in an avatar repository. A beneficiary of assets or rights controlled by the expired avatar may be determined. When there is no nominee, an NFT that indicates that there is no nominee may be recorded on the blockchain, and legal authorities may handle the disposition of the assets or rights of the expired avatar.
