This invention relates to a system and method for securing property ownership records through a secure tamper-proof biometric verification and blockchain technology; Biometric Identity Lock Instrument (BILI). The invention Biometric Identity Lock Instrument (BILI) captures a property owner's biometric data, encrypts it, integrates biometric authentication to property deeds, links it to a blockchain-based registry, and legal frameworks. The system generates secure documents for locking and unlocking transactions, preventing unauthorized property transfers and mitigating fraud. The BILI document is generated with a unique QR code and serial number for dual physical-digital verification, ensuring transparency and security in real estate transactions. This method is particularly applicable to real estate and government-backed loan systems.
Resumen de: US2025217890A1
A method for detecting and tracking tainted cryptographic wallets. The method measures a wallet's propensity to engage in criminal or suspicious activity. Naturally, transacting with a criminal is tantamount either to funding crime or laundering its proceeds, so it is in our collective interest to identify—and then monitor or quarantine—any wallet with criminal association. The method also automatically flags risky withdrawal requests in real-time for further review before committing them to the blockchain. In some embodiments, the exchange can quarantine wallets at a certain AddressScore.

A service provider of data services (e.g. cloud, videoconferencing, streaming) over networks provides at least one address 2002 (preferably IPv6 addresses including multicast addresses) to a device controller when the device controller registers 2001. The service provider and device controller also agree cryptographic keys between themselves 2003-2008. When a device associated with the device controller requires access to the service provider the device controller provides one of the addresses and a derivative sub-key of the agreed key to the device 2009. The device signs a request to the service provider with the sub-key 2010. The service provider uses the devices address to look up the agreed key, derive the sub-key and check the signature on the request 2011. If the request is validated the service is provided 2013. The service provision may involve a blockchain in some manner.

Alice provides this information plus her signature. Bob can then perform local SPV checks on the input transactions Tx1, Tx2 using transactions Tx1 and Tx2, their corresponding Merkle paths Path 1, Path 2, and Error! Bookmark not defined. Bob's local list of block headers. Bob broadcasts the transfer transaction (Tx3) to the P2P network.

Systems and methods described herein relate to techniques in which multiple parties each generate and exchange quantities that are based on a shared secret (e.g., powers of the shared secret) without exposing the shared secret. According to a protocol, two or more parties may exchange sets of elliptic curve points generated over polynomials that can be used, by each of the two or more parties, to determine a power of a shared secret. The protocol may be utilised as part of determining parameters for a smart contract that is broadcast to a blockchain network (e.g., Bitcoin). Based on the protocol, an additional party (e.g., a third party different from the two or more parties) may perform a computational task such as execution of the smart contract.

To request that an unlocked script of a transaction in a blockchain includes a block header, a blockchain, or a chain of block headers.SOLUTION: A method includes receiving, at a node in a blockchain network, a first transaction associated with a digital asset. The first transaction includes a first script that specifies a set of constraints on a second transaction to transfer control of the digital asset, and the set of constraints includes a constraint that a set of data obtained by the node includes information obtained from a blockchain associated with the blockchain network. The method obtains the second transaction. The second transaction includes a second script that, as a result of being executed, causes the node to obtain the set of data. The method further validates the second transaction by executing the first and second scripts.SELECTED DRAWING: Figure 1

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.

Systems, apparatus, and methods for transacting, recording, validating and/or verifying agricultural products and its proceeds. The 2018 Farm Act rescinded industrial hemp from Schedule I of the Controlled Substances Act (CSA). Although industrial hemp has a variety of uses, the Government's biggest concern is the ingestion of tetrahydrocannabinol (THC) and cannabidiol (CBD). Commercial regulation typically balances a variety of factors: e.g., consumer protection, regulatory overhead, market competition, tax revenue, public policy, etc. In contrast, law enforcement has a singular purpose, and may go to extraordinary lengths to stop criminal activity. Various embodiments described herein provide a blockchain ledger-based supply chain that allows many commercial and regulatory entities to independently cooperate. Every transaction is permanently and transparently recorded within a chain-of-custody; the chain-of-custody enables a traceability; transitive linkages enable regulatory compliance. A variety of new applications are enabled by the blockchain ledger-based supply chain.
