Abstract: A method and system of providing a service node within a blockchain network. The method includes storing, in a memory of a processing server, a blockchain comprised of a plurality of blocks, wherein each block is comprised of at least a block header and one or more data values, wherein the one or more data values included in a most recent block includes at least one data point associated with services or functions of at least a first service node; receiving, by a receiving device of the processing server, a request from a second service node for the list of services or functions of the at least a first service node within the blockchain network; and validating, by the processing server, the request from the second service node for the list of services or functions of the at least a first service node within the blockchain network.

Abstract: Systems and methods for interpreting a user's brain wave data from EEGs using machine learning algorithms are described. In one example, a brain activity interpretation system classifies the EEG recording into five separate component signals, representing the five categories of brain waves (alpha, beta, theta, delta, gamma). In one example, the most dominant component signal is analyzed to determine whether the amplitude is higher or lower than an optimal range within the bandwidth for that brain wave. The system can then provide intelligent recommendations to the user for beneficial action(s) to help improve their everyday functioning and promote better regulation of their brain states. The system can help the user become more aware of their mental state and how to improve their mental state. EEG data is highly complex and unsuitable for immediate human comprehension, thus, the disclosed systems and methods improve the speed and accuracy of brain wave analysis.

Abstract: Delegating issuance capability to a third-party of fungible digital assets involves a central (e.g., central bank) processor receiving a request to issue fungible digital assets from a third-party node; verifying the request; validating request to issue fungible digital assets from the third-party; approving or rejecting the request; if the request to issue fungible digital assets is approved, creating an issuance authorization message; executing a smart contract clause to add an entity of the third-party node to a list of authorized entities; publishing the issuance authorization message on a blockchain indicating that a third-party node has been added to the list of authorized entities; and publishing a revocation message on the blockchain revoking an authorization granted to the third-party node to issue digital assets.

Abstract: The disclosed method includes: receiving, by a receiving device of a processing server, a transaction request for a financial transaction, the transaction request including at least information associated with a consumer; forwarding at least the information associated with the consumer, the information associated with the merchant, and the transaction amount or projected transaction amount to an issuer; receiving an authorization from the issuer for the transaction amount or projected transaction amount; forwarding the authorization to the merchant; receiving a triggering event for the financial transaction between the consumer and the merchant; sending a request to the issuer for digital tokens to be held for payment of the transaction between the consumer and the merchant; receiving a plurality of digital tokens from the issuer for the payment of the transaction between the consumer and the merchant; and holding the plurality of digital tokens received from the issuer for the financial transaction.
