Secure blockchain (BC)-based tokens are issued and linked to payment cards and/or devices of customers. Custom conditions associated with the tokens are stored in smart contracts on a BC. The tokens are stored in a cloud-based key vault and/or in the BC. Validation of a token for access a smart contract on the BC can only be made by a financial institution (FI) to the key vault. Real-time information for a transaction device, for transaction information, and/or for the customer is provided as input data to the smart contract for evaluation of the conditions. After the token is authenticated by the key vault, the real-time information is gathered and passed to the corresponding smart contract on the BC for evaluation. The FI receives transaction authorization or transaction denial based on the smart contract's evaluation of the conditions.

Resumen de: EP4576647A1
The invention relates to a method and a system for multidimensional Blockchain mining. The method makes use of a purposely delay of the time frame of the block mining in order to use the information in the block at hand as a relay to route in specific targeted node elements. The delay, which is performed on the block mining, targets the reshaping (editing) process in the blockchain implemented in this solution. By delaying the mining, the number of blocks that is otherwise needed to be edited is limited. Additionally, a chain is obtained that is more solid with regards to its incident information contents. The technical advantage of this action is depicted in the search operations performed over the optimized chain once it is edited. The above changes result in lower usage of server resources giving the opportunity to handle more events with the same number of resources.

Resumen de: US2025200682A1
The present invention introduces a dual-chain property management system that integrates blockchain-based tokens with off-chain government and institutional property records to provide secure, verifiable, and legally recognized asset transactions. Unlike existing blockchain-based property solutions, this system prevents unauthorized tokenization, enforces compliance with jurisdictional property laws, and synchronizes title records dynamically. A concurrency management module eliminates double-minting risks, while a discrepancy resolution engine continuously detects and corrects mismatches between blockchain and legal registries. Smart contracts automate ownership transfers, lease agreements, lien tracking, and compliance enforcement, ensuring fraud-resistant transactions in real estate, vehicles, intellectual property, luxury goods, and financial instruments. This innovation enables legally binding digital property transfers with real-time regulatory oversight, bridging the gap between decentralized asset tokenization and traditional legal frameworks. By automating verification, synchronization, and compliance, the system creates a scalable, transparent, and jurisdictionally compliant property management ecosystem.
