SYSTEMS AND METHODS FOR BLOCKCHAIN-BASED AUHTENTICATION AND FOR NOVELTY DETECTION

Resumen de: US2025350470A1

System and methods for physical authentication using blockchain technologies. A user list is encoded via hashes of respective wallet addresses to construct a Merkle Tree. The Merkle Root of the constructed Merkle Tree is recorded on the blockchain. The Merkle Tree and the Merkle Root are updated each time a user is added to the organization. A user is authenticated by submitting a message to the client, which creates a Merkle Proof and sends it to the blockchain for authentication. The process can be facilitated by a mobile application that generates a Quick Response (QR) code representing the user's wallet address.

USING AN INTERNAL LEDGER WITH BLOCKCHAIN TRANSACTIONS

Resumen de: US2025348864A1

Systems, methods, and computer-readable media disclosed herein relate to reducing computation and computing resources for certain blockchain related transactions. Specifically, software algorithms and architecture allow some transactions to avoid the need for recordation on a blockchain, which can be computationally expensive both for a requesting device and for various nodes on the blockchain. Thus, a computer system may receive indications of incoming transactions transferring digital assets to particular user accounts, and in response to requests from user accounts, the computer system facilitates one or more internal transactions between those accounts. In response to a request from a particular internal user account, the computer system may perform an outgoing transaction transferring one or more digital assets to an external user account from one or more internal user accounts. The incoming transactions and outgoing transaction are recorded on the blockchain, but the internal transactions are recorded on an internal ledger rather than the blockchain, saving computational power and improving computer operations.

Verifying requests

If each node keeps a local blockchain then all verified requests can be added. The invention comprises comparing 204 a candidate trusted value received with a request with a trusted value stored at each node of the plurality of nodes, generating 205 a yes vote if the candidate trusted value matches the trusted value stored at a respective node, and verifying 208 the request if the number of yes votes across the plurality of nodes exceeds a predetermined threshold. Trusted values may be a hash of data contained within a preceding request. Each node of the plurality of nodes may store the series of requests on a local blockchain stored on that node, with verified requests added to the local blockchain as they are verified.

Resumen de: US2025342426A1

Systems, devices, and methods provide for risk management between a source blockchain and a destination blockchain. A risk management network monitors transactions taking place utilizing a cross-chain interoperability protocol. The risk management network is separate from the transaction network.
