Resumen de: US20260221240A1
Systems and methods for tracking samples via sample tracking chains are presented. Sample tracking chains represent digital data structures instantiated according to intrinsic properties of a sample. Each link in the chain is a block of data representing an observed intrinsic state of the sample and is linked at least to a previous block representing a previous state. The sample tracking chain and blocks can be indexed for later retrieval by the intrinsic properties of the corresponding sample's state. The sample tracking chain can take the form of a blockchain possibly stored as part of a private or public distributed ledger. Disclosed sample tracking chains provide a full life cycle audit trail for sample processing.

There are provided systems and methods for intelligent detection and acquisition of authentic product reviews for cross-platform availability. A service provider may provide computing services to merchants and users for processing various interactions, such as purchasing items electronically. When items or other products are purchased, users may leave reviews. To determine an authenticity of the reviews, the service provider may utilize an intelligent system that may include an LLM or other generative AI. The system may automatically generate questions for users that may be designed by the LLM to elicit responses that verify whether a review is authentic and/or relevant. This may include receiving responses and scoring those responses to verify the user is providing an authentic review. If so, the review may be written to a blockchain, which may allow the review to be pushed to users and/or automatically injected to product pages and checkout flows.

0000 A zero-knowledge CBDC (zkCBDC) banking system uses zero-knowledge proofs to prove that commercial banks are processing transactions correctly. Commercial banks are the provers of the zero-knowledge proof system. The banks generate a zero-knowledge proof for one or more transactions processed by the bank. The banks also generate a hash of the total amount of the transaction(s). The zero-knowledge proof and associated transaction hash are submitted to a blockchain. The blockchain stores a bank state commitment value for each commercial bank in the system and includes a smart contract with code for verifying the zero-knowledge proofs. Once a proof is verified, the bank's state commitment value is updated and the transaction hash is added to the verifier's state.

The delta value is indicative of a difference between a total number of tokens having an attribution property in circulation of the source blockchain and a number of tokens having the attribution property in circulation of the source blockchain that are accounted for by one or more vaults of one or more primary blockchains. The attribution property identifies a token issuer. The method further includes causing the transaction payload to be applied to the destination blockchain to perform the cross-chain operation, wherein the cross-chain operation is performed with an associated space complexity that, based on use of the delta value for token reattribution, is sublinear with respect to a total number of token issuers.
