Active Metadata and Reinforcement Learning to Improve TPS Processing

Resumen de: US2025252436A1

Innovative systems and methods address the challenges in blockchain transaction processing, particularly in Proof of Work (POW) and Proof of Minting (POM) consensus mechanisms. These challenges encompass slow transaction processing, network congestion, high resource consumption, transaction prioritization issues, scalability limitations, environmental concerns, and the trade-off between security and efficiency. To mitigate these issues, innovative solutions combine active metadata and reinforcement learning to optimize cryptocurrency transaction processing, enhancing the Transactions Per Second (TPS) rate in Crypto Mining and Minting. Users initiate transactions, which are queued with detailed information. Active metadata efficiently processes and assigns transactions, while reinforcement learning dynamically adjusts block sizes based on transaction sizes. This streamlines transaction processing, incentivizes efficient block creation, and improves overall blockchain network performance. Key features include advanced queue management, dynamic block sizing, and a TPS-based reward system. The inventions revolutionize cryptocurrency transaction processing, promoting efficiency, fairness, and sustainability in blockchain networks.

Computer-implemented methods and systems

Resumen de: GB2637788A

The invention provides solutions for securing and verifying data, controlling access to controlled resources, proving identity and/or authorisation by implementing agreements between computer-based resources. For example, a first node (Alice) sends an encrypted challenge to a second node (Bob). The challenge can also be called a puzzle. The challenge has been encrypted using the Bob’s public key. Upon receipt, the Bob uses his corresponding private key to decrypt Alice’s challenge. This enables him to compute a solution and send it to Alice as proof that he must have decrypted her challenge and must, therefore, have knowledge or possession of the private key. If Bob does not have the private key, he is unable to decrypt the challenge and provide the correct solution. Some embodiments can be implemented using a blockchain for provision and execution of the challenge and/or solution.
