0000 Certain aspects of the present disclosure provide techniques for multi-blockchain token rebalancing. According to certain embodiments, a target ratio defining a first quantitative relationship between an amount of a token present is determined for each of a plurality of blockchains. A current amount of the token is received for a first blockchain, and in some embodiments, a first ratio is generated for the token present on each of the plurality of blockchains, based on the current amount. The current amount is compared to the target ratio to generate a ratio difference. Based on the ratio difference, a rebalancing transaction is executed on the first blockchain to bring the amount of the first token closer to the target ratio for the first blockchain.

Resumen de: WO2026132622A1
The present invention relates to a comprehensive system designed to prevent and control fraudulent sales, understood as any type of unlawful transaction, including the sale of counterfeit, stolen or illicitly acquired goods. This system assigns unique public codes to goods and services, linking them to registered owners and providing complementary secret codes that can only be accessed by these owners. This combination ensures the authenticity, traceability and security of the goods and services at any stage of their life cycle. The system allows owners to transfer ownership in a secure and authorised manner without the buyer having direct access to the secret code, thereby protecting the integrity of the process. In addition, it allows transfer authorisations to be delegated to third parties in a controlled and secure manner. During each transaction, the system automatically updates the ownership record, disables the previous secret codes and generates new unique secret codes for the new owner, thereby strengthening security and preventing duplications or fraud. The platform that supports the system can be implemented in both centralised environments, with a main data-management server, and decentralised environments using technologies such as blockchain to distribute and protect information. This technological flexibility allows the system to adapt to different infrastructures and operating models, thereby ensuring an effective implementation in a wide variety of contexts.
