Resumen de: WO2024161335A1
Embodiments of the present invention provide a system for blockchain-enabled documentation of trade transactions. The system includes buyer and seller devices for transaction execution, a processor, and a memory unit storing instructions. The system receives transaction documents from these devices, compiles them for each trade, and watermarks them with a Unique Acceptance Code (UAC). It generates a unique hash, either an Inspection Report Code (IRC) or a Commercial Invoice Code (CIC), for each document, acting as a distinct identifier. These hashes, alongside event types and timestamps, are recorded on the blockchain to ensure transaction data's immutability and transparency. Additionally, the system generates a blockchain certificate for each recorded event, confirming transaction completion and authenticity. This setup leverages the blockchain's inherent properties to provide a secure, verifiable record-keeping system for agricultural trade documents.

A blockchain oracle manages loans collateralized by a digital asset. Lenders and borrowers agree to loan terms that include digital asset collateral held in a multisig wallet for which various parties hold private keys. If collateral requirements are not met by the loan such as when a Loan-to-Value ratio satisfies a margin call condition, the oracle may transmit warnings to loan participants and may initiate liquidation of the digital asset collateral to remove the margin call condition. The oracle may exist on a blockchain initialized with loan agreement information. The oracle may determine whether margin call and liquidation conditions are satisfied by updating an internal state by obtaining and/or receiving information regarding the status of the loan, the digital asset collateral, and liquidation locations on-chain, by receiving status transactions, and/or by requesting the information directly.

Resumen de: US2024265392A1
Trustless deterministic state machines can be implemented using a blockchain infrastructure and state machines can run concurrently over more than one blockchain transaction. The transactions can be done in a Bitcoin blockchain ledger. An unlocking transaction constraint that constrains an unlocking transaction to include a transaction input that references a previous transaction output is determined. A redeemable transaction is created to include a transaction output that includes an amount and a transaction locking script that includes the unlocking transaction constraint, with unlocking the amount being contingent upon execution of at least one unlocking script of the unlocking transaction satisfying the unlocking transaction constraint. The redeemable transaction is caused to be validated at a node of a blockchain network.

Each item's packaging label displays a scannable code, such as a Quick Response (QR) code, into which a nonfungible token (NFT) associated with the item has been encoded. A handheld device can be used to scan the scannable code, convert it into a data signal, extract the NFT from the data signal, process the NFT to obtain a unique identification (ID) of the item, and forward the unique ID to the blockchain network. The blockchain network processes the unique ID to authenticate the item, retrieves the data that was used to create the NFT from memory if authentication is successful, and forwards the retrieved data to the handheld device. The handheld device receives the forwarded data, processes it and causes it to be displayed on the display device of the handheld device to show the user that the item has been successfully authenticated by the blockchain network.
