A system and method of optimizing cryptographic mining yields includes analyzing, by a cryptocurrency mining selection system, data associated with factors of interest for one or more cryptocurrencies using machine learning algorithms. Data that is determined to be predictive of the future value of newly mined tokens is used to determine which tokens will have the highest and lowest future values. Based on the predicted value of tokens in the future and the current value of those tokens for each cryptocurrency, the system outputs one or more instructions to buy tokens in cryptocurrencies predicted to increase in value, to sell tokens in cryptocurrencies predicted to decrease in value, and to instruct associated cryptocurrency mining hardware to switch to generating new tokens in one or more selected cryptocurrencies to maximize yields.

Systems and methods are described for authorizing users and/or devices. An example method may comprise receiving, from a user device, a request to access a function associated with a service account. The request may comprise an identifier of the user device. The example method may comprise determining, based on the identifier, a primary authority holder of the service account. The example method may comprise determining that a first record on a first distributed ledger associated with the primary authority holder indicates that the user device is associated with the primary authority holder. The example method may comprise determining that a second record on a second distributed ledger associated with the user device indicates that the user device is associated with the primary authority holder. The example method may comprise granting, based on the request, the first record, and the second record, the user device access to the function.

In one aspect, a distributed ledger system include a first network node configured to detect a triggering condition for processing a claim; collect user and broker information for processing the claim; convert the information from a first computer-readable format to a second computer-readable format; validate the converted information based on corresponding digital signatures; generate claim state objects based on the validated information to be used by each node of the distributed ledger system to execute a smart contract for processing the claim; receive one or more updated claim state objects from a second network node reflecting updated processing status of the claim to be used by each node of the distributed ledger system to execute the smart contract for processing the claim; and process the claim based on results of execution of the smart contract using the one or more updated claim state objects.

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.

A system and a method of data communication between a first computing device, associated with a first user, and at least one second computing device associated with a second user may include: receiving, by the first computing device, one or more data elements pertaining to details of a transaction request from the second computing device, via a voice channel; extracting said transaction request details by the first computing device; transmitting, by the first computing device, one or more authentication data elements of an electronic wallet module, comprised in the first computing device, to the second computing device, via the voice channel; and carrying out the requested transaction by the first computing device, based on the extracted transaction request details and the electronic wallet authentication data.

A management system includes a user terminal, and a management device that manages data, wherein the management device include a memory; and a processor coupled to the memory and executes a process comprising: requesting remittance of a cryptocurrency that uses a public distributed ledger from the user terminal, upon receiving a request for accessing managed data from the user terminal, and authorizing the user terminal to access the data when a record of clearance of the remittance made by the user terminal is added to the public distributed ledger.

A computing system can establish asynchronous network communications with exchanges to facilitate cross-medium transactions between originating and recipient clients. Such communications can result in filtering out errant responses that would otherwise cause an open transaction to fail.

Computer-implemented methods for locking a blockchain transaction based on undetermined data are described. The invention is implemented using a blockchain network. This may, for example, be the Bitcoin blockchain. A locking node may include a locking script in a blockchain transaction Node to lock a digital asset. The locking script includes a public key for a determined data source and instructions to cause a validating node executing the locking script to verify the source of data provided in an unlocking script by: a) generating a modified public key based on the public key for the determined data source and based on data defined in the unlocking script; and b) evaluating a cryptographic signature in the unlocking script based on the modified public key. The blockchain transaction containing the locking script is sent by the locking node to the blockchain network. The lock may be removed using a cryptographic signature generated from a private key modified based on the data.

Disclosed are methods and systems for quantifying degrees of association between blockchain addresses in a weighted-linked database. The method may include: obtaining a node data set comprising one or more nodes and edges; associating a first node of the node data set with a first weight factor; identifying a first edge of the node data set, wherein the first edge comprises data indicating a source node address corresponding to the first node, a target node address corresponding to a second node of the one or more nodes in the node data set, and a first edge weight; determining a source value for the second node based on the first weight factor and the first edge weight; generating, a risk value for the second node based on the source value; and presenting, on a GUI, graphical depictions of the first node, the second node, and the first edge.
