A method for optimized validation of a blockchain transaction through the use of a parallel database and date management includes: receiving a new blockchain transaction that includes unspent transaction outputs; identifying, in a parallel database, a start date for a blockchain wallet involved in the new transaction; identifying a subset of blocks in the blockchain that have been added to the blockchain since the start date; validating the new blockchain transaction by validating the unspent transaction outputs using the subset of blocks; and, if the validation is successful, adding the new transaction to the blockchain, or, if the validation is unsuccessful, notifying the submitter of the failed validation.

A method and a system for conducting a transaction using an electronic chip are provided. One or more details of a plurality of payment modes and a first authentication parameter are stored in the electronic chip. The electronic chip receives an authentication request including a second authentication parameter from a terminal device when the transaction is initiated at the terminal device. The electronic chip compares the first and second authentication parameters, and communicates an authentication response including one or more details of a first payment mode of the plurality of payment modes to the terminal device based on a match between the first authentication parameter and the second authentication parameter. The transaction is processed based on the authentication response.

The disclosed subject matter includes methods, systems, and networks for authentication based on physical characteristics of a mobile device. A computer-implemented method performed by a payment network includes receiving an image of a part of a mobile device from an image capturing device that communicates with the payment network, wherein the mobile device includes digital card data of a customer. The computer-implemented method may also include comparing a physical condition of the part of the mobile device shown in the received image to the physical condition of the part of the mobile device shown in a stored image. In addition, the computer-implemented method may include authenticating or declining a transaction involving the digital card data based on the comparison of the physical condition of the part of the mobile device in the received image and the stored.

A method and system for disbursing loyalty points is provided. A server receives loyalty points disbursement (LPD) parameters including at least an initial earn rate, a loyalty points budget, and a disbursement period. The server receives an LPD request corresponding to a transaction performed by a user. The server updates the initial earn rate based on at least one of real-time transaction data, predictive transaction data, real-time market disbursement data, and predictive market disbursement data. The server disburses a first set of loyalty points, from the loyalty points budget, to the user based on at least the updated earn rate and a transaction amount of the first transaction.
