A computer-implemented method comprises obtaining meta-descriptors of a nature-based asset and a region of a water environment in which the asset is located at 102, and mapping dimensions of the asset at 103. Data of monitored physical characteristics of the asset in the environment is accessed based on the meta-descriptors of the asset at 104, and data of monitored carbon concentration in the region of the water environment and on monitored physical, chemical, and biological properties of the environments are accessed based on the meta-descriptors of the region at 105 and 106. A model is applied to the accessed data to assign a carbon sequestration contribution per unit measurement of the nature-based asset at 107. A system comprising a processor and memory and meta-descriptor, mapping, asset data monitoring, carbon concentration data, water environment data and model applying components for performing the method is further provided.

Resumen de: US2025156583A1
This application provides methods and systems for verifying safe, consistent and secure storage of data especially, but not limited to, situations where storage of the data is delegated to a third party. A data controller, Alice, takes at least one sample of her data D, performs an operation on it to produce a variation. She then calculates the root value of the Merkle tree that represents the data comprising the varied data sample. She sends her data to a storage provider, Bob, while retaining her sample(s) and the resulting Merkle root value(s). Alice does not tell Bob which sample(s) she has chosen, or the operations she has used in the variations, or any inputs to the operations. Alice can delete her original copy of the data. At a later date, Alice can verify that Bob still has her complete data and in its original state by requiring him to perform the same operation on the same data sample, calculate the root value of the resulting Merkle tree and send it to her. If Bob's root value matches Alice's root value, then Bob must have an original and complete copy of Alice's data otherwise he would not be able to calculate the correct Merkle root value. Embodiments can be arranged to fully automate the process, including implementing on a blockchain.

The present disclosure relates to systems and methods for facilitating interoperability between blockchain networks to facilitate bridging of non-fungible tokens (NFTs) across chains. In embodiments, a method includes receiving a bridging request at a first bridge smart contract to transfer a source NFT from a first blockchain to a second blockchain. Upon verification, the first bridge smart contract locks the source NFT. An oracle server determines whether a clone NFT associated with the source NFT exists on the second blockchain. If so, the oracle instructs a second bridge smart contract to unlock the clone NFT. If no clone NFT exists, the oracle instructs minting of the clone NFT and assigning ownership of the clone NFT to the user's account on the second blockchain. The clone NFT remains controllable by the user while the source NFT stays locked on the first blockchain, maintaining a one-to-one relationship between the tokens across chains.

Resumen de: US2025156920A1
The embodiments of the present invention are related to automatically capturing, logging, rating, scoring, and tracing attributes of a product against known data sets and storing that information as a point-in-time capture that cannot be edited. The platform can capture, rate, score, trace, and distribute content for the health and sustainability factors/attributes of a product. A multifactor holistic scoring process is implemented that produces a reliable estimate of the sustainability of the product (in context). Related data and the score (in connection with timing information) are saved when the product (or product lot) is updated in content or manufacturing. A digital blockchain ledger is integrated by way of interaction with the system to store individual input and the score and configured to securely store the data, rules, or other items that resulted in the score. Individual data items are stored in the ledger and include an identifier.

Introduced here is a computational architecture (also referred to as a “computational infrastructure”) that addresses the limitations of traditional data management solutions using a highly secure data management solution coupled with consent-based sharing. At a high level, the computational architecture applies blockchain methodologies to both transaction data and business data such that both types of data are stored “on chain” in the same computational architecture. This enables several significant advantages over traditional data management solutions with respect to data security, data ownership, data sharing, and intelligence.

Resumen de: US2025158981A1
An improved gossip-protocol-based method, a device, a piece of equipment and a medium for incentivizing block propagation. By improving the Gossip protocol and embedding block propagation rewards, the block forwarding process is accelerated. The designed signature chain structure records the block forwarding path and ensures that the path information is not tampered with. By combining the signature chain structure with the block generation process, the rewards are ensured to be truly and reliably distributed. A block propagation reward distribution strategy is designed to prevent forwarding nodes from adding pseudonyms in the propagation path. Therefore, the method can reduce the blockchain stale rate and enhance the scalability and consensus performance of the blockchain by accelerating block propagation in the presence of selfish nodes, and addresses the problem that selfish nodes refuse to forward blocks to save communication consumptions in the current blockchain network.
