Intelligent and Autonomous Layered Platform to Orchestrate Vulnerability Solution in a Cross Chain Environment

Resumen de: US12700005B1

0000 This invention provides a system and method for managing and securing cross-chain blockchain transactions through a layered, autonomous platform. It features a source orchestration layer employing optimistic replication and polymorphic encapsulation to ensure data redundancy and traceability. Transactions are encrypted and transmitted using an asynchronous handshake protocol that integrates bidirectional acknowledgment exchanges to validate transaction integrity. A destination orchestration layer decapsulates and verifies acknowledgment data, generating secondary acknowledgment requests for added validation. Transactions are validated by a blockchain of validators utilizing consensus mechanisms, such as proof-of-stake or proof-of-work, which produce cryptographic proofs of validation. Failed or suspicious transactions are isolated in a dead letter log, enabling further analysis and prioritization. The system combines advanced cryptographic techniques, redundancy algorithms, and decentralized consensus to enhance security, mitigate vulnerabilities, and ensure reliable operation in cross-chain environments. This invention optimizes transaction processing while addressing challenges such as scalability, data integrity, and malicious activity.
