A method for managing operational costs associated with distributed computing. The method includes: creating, via a graphical user interface (GUI), a distributed computing team; linking a digital team wallet to the distributed computing team, wherein the digital team wallet is linked to a currency account; adding a member to the distributed computing team; allowing the member to purchase compute resource access from a plurality of compute resource providers using the digital team wallet; and notifying a team manager when funds in the digital team wallet reduce to at least a team threshold value.

Mechanisms for efficiently transferring multiple unspent transaction output (UTXO) tokens in a blockchain network operating a UTXO-based token transaction model are disclosed herein. These methods allow for the use of less computer processing and network bandwidth resources in the transfer of blockchain items, particularly in blockchain schemes with lineage tracking mechanisms (e.g. as may allow for clawback of tokens). Some embodiments comprise generating a delegated account and transferring the UTXO tokens into the delegated account. The ownership of the delegated account can then be transferred to another use of the blockchain network in a single transaction, thereby avoiding the need to individually transfer the UTXO tokens and incur the memory and computational resource burden and costs associated with therewith.

Methods and systems including: receiving a request to take an action in a cryptoasset custodial system for an account holder; authenticating a policy map associated with the action, wherein the policy map defines access control rules governing which actions are allowed under conditions including a threshold number of endorsements needed; and validating endorsement messages for the action by checking digital signatures of the received endorsement messages, wherein at least one of the validated endorsement messages has been generated by digital signing with a first private key of a person, who is associated with the account holder, and at least one of the validated endorsement messages has been generated by digital signing with a second private key of a program, which is associated with the account holder, responsive to the program confirming one or more circumstances specified by the account holder are met at a time when the program is run.

The invention provides a method and corresponding system for controlling a blockchain transaction output and/or specifying the recipient of the output. It also provides a method of controlling and/or generating an electronic communication. The invention is a blockchain-implemented solution, which may or may not be the Bitcoin blockchain. In a preferred embodiment of the invention, the method may comprise the step of sending an electronic notification to a notification address which is provided as metadata within an unlocking script of an input of a transaction (Txi) on a blockchain. The unlocking script is provided in order to spend an output from a further transaction (Tx2) on the blockchain. The input of the transaction (Txi) and/or the output of the further transaction (Tx2) may be associated with a tokenised asset represented on, or referenced via, the blockchain. The notification address may be associated with an asset or resource represented on the blockchain, or a controller of an asset or resource represented on the blockchain. The notification address may be a network address, a cryptographic key, a uniform resource locator (URI), email address or any other address or identifier which can be represented in the metadata of a transaction script and used as a destination for an electronic communication.

Systems and methods for verifying a digital title of an asset transferred via a math-based currency transaction. The method includes receiving a digital title request regarding an asset, creating a digital title for the asset in a digital title database, receiving, from a financial institution computing system, an asset transfer request regarding the asset that is the subject of the math-based currency transaction, verifying that an identity of a seller in the math-based currency transaction matches the identity of the owner of the asset. Then, responsive to the verification that the identity of the seller in the math-based currency transaction matches the identity of the owner of the asset, the method includes transmitting, to the financial institution computing system, a positive title verification and updating the identity of the asset of the digital title for the asset to match an identity of a buyer in the math-based currency transaction.

A system that deploys a first smart contract that include a set of predefined functions that enable exchange of a first cryptocurrency on a first blockchain network. Additionally, the system deploys a second smart contract with the set of predefined functions that enable exchange of a second cryptocurrency on a second blockchain network. Furthermore, the two sets of smart contracts allow for the blockchain operations to be conducted by referencing an exchange platform supported by the system. By referencing the exchange platform, the corresponding sets of functions may be activated to perform exchanges across the blockchain networks.

Systems, methods, and non-transient machine-interpretable data representing executable instruction sets and/or other products for the processing of data for the 5 secure creation, administration, manipulation, processing, and storage of electronic data useful in the processing of payment transactions and other secure data processes. In various aspects and embodiments the disclosure provides secure means for the authorization of sensitive and other data processes subject to controlled access. Such processes include, for example the creation, administration, 10 authorization, virtualization, storage, and other manipulation or processing of electronic data representing characteristics of, instructions for, and information associated with consumer, business, and other payment accounts, and other forms of secure payment elements, such as payment tokens; and data useful in processing transactions using such accounts and elements. Information associated with 15 particular payment means, such as accounts or payment tokens, can be stored, for example, in a data set, usually secure, sometimes referred to as a virtual or electronic wallet, or a secure payment token.

An integration platform provides a third party channel products from a merchant, so that the third party channel may cause an opportunity to be presented to a user to purchase one of the products. In response to an indication of a user purchase, the integration platform transmits a purchase request to the electronic commerce platform to create an order for the purchase. The integration platform may create a payment for the purchase with the merchant's payment processor and transmit the payment to the payment processor, update the order with the merchant's electronic commerce platform with the payment information, update the status of the order to shipped, and capture payment information by communicating with the payment provider. The merchant's electronic commerce platform may then update the order with the integration platform, which may notify the third party channel of the update so that update may be communicated to the user.

A method for authenticating a consumer. The method includes receiving an authorization request message associated with a consumer conducting a transaction with a portable consumer device. A challenge message is sent to the consumer, where the challenge message is dynamic or semi-dynamic. A challenge response message is received from the consumer, and an authorization response message is sent to the consumer. The authorization response message indicates whether or not the transaction is authorized.

In some implementations, a transaction card may receive transaction data from a transaction terminal based on initiation of a transaction with the transaction terminal; generate a tokenized primary account number, for use with the transaction, based on the transaction data and an actual primary account number of the transaction card; and transmit the tokenized primary account number to the transaction terminal for processing the transaction.
