Device, method, and computer readable medium for large scale electronic processing

A method for a device in a blockchain network that communicates over a computer network with a first external computer terminal, one or more second external computer terminals, and at least two external entities, the device comprising a memory configured to maintain data of an electronic transaction, predetermined thresholds, and external identification information, and circuitry, the method comprising:

• adding, by the circuitry, at least one transaction block to a chained sequence of one or more blocks, including:
• receiving, over the computer network from the first external computer terminal, a request message having the data of the electronic transaction,
• broadcasting, over the computer network to the one or more second external computer terminals, an alert message alerting of the request message,
• receiving, over the computer network from the one of the one or more second external computer terminals, a response message having counter transaction data that relates to the alert message,
• determining a match between the transaction data and the counter transaction data,
• broadcasting, to a plurality of nodes in the blockchain network, a consensus request message for generating the at least one transaction block as an immutable record of the transaction data and the counter transaction data, the generating the at least one transaction block includes creating a block header that contains a hash pointer that has a hash of a block header of a block that the at least one transaction block is linked to,
• receiving, from one of the plurality of nodes, a message indicating that consensus has been achieved, and adding the at least one transaction block to the chained sequence,
• updating the data of the electronic transaction and comparing the data, including at least one of an updated rate and spread related to valuation of an item having value that is tied to the transaction data, to the predetermined thresholds to obtain a comparison result, wherein the transaction data and the counter transaction data include a value at a future settlement date, an initial posting of the value of the item, a currency pair and a forward exchange rate,
• determining the value of the item after the initial posting,
• establishing movement of the item between the external entities based on a final value of the item,
• settling the movement of the item on the future settlement date,
• broadcasting a consensus request message for creating a data block as an immutable record of the currency pair and the forward exchange rate, and
• performing an action based on the comparison result including performing an updated valuation of a contract and sending an alert message;
• and
• concurrently with the updating, comparing and performing an action, performing, by the circuitry, periodic valuation and transmission of the item having the value that is tied to the transaction data, including:
• transmitting messages to the external entities associated with the external identification information,
• establishing transmission links with the external entities including links between respective custodian accounts of the external entities with the transaction and a ledger,
• determining a value of the item, and
• establishing movement of the item between the external entities based on the determined value of the item and the predetermined thresholds.

A non-transitory computer-readable storage medium including computer executable instructions, wherein the instructions, when executed by a computer, cause the computer to perform a method, the method comprising:

• adding at least one transaction block to a chained sequence of one or more blocks, including:
• receiving, over a computer network from a first external computer terminal, a request message having the data of the electronic transaction,
• broadcasting, over the computer network to one or more second external computer terminals, an alert message alerting of the request message,
• receiving, over the computer network from the one of the one or more second external computer terminals, a response message having counter transaction data that relates to the alert message,
• determining a match between the transaction data and the counter transaction data,
• broadcasting, to a plurality of nodes in a blockchain network, a consensus request message for generating the at least one transaction block as an immutable record of the transaction data and the counter transaction data, the generating the at least one transaction block includes creating a block header that contains a hash pointer that has a hash of a block header of a block that the at least one transaction block is linked to,
• receiving, from one of the plurality of nodes, a message indicating that consensus has been achieved, and adding the at least one transaction block to the chained sequence,
• updating the data of the electronic transaction and comparing the data, including at least one of an updated rate and spread related to valuation of an item having value that is tied to the transaction data, to the predetermined thresholds to obtain a comparison result, wherein the transaction data and the counter transaction data include a value at a future settlement date, an initial posting of the value of the item, a currency pair and a forward exchange rate,
• determining the value of the item after the initial posting,
• establishing movement of the item between the external entities based on a final value of the item,
• settling the movement of the item on the future settlement date,
• broadcasting a consensus request message for creating a data block as an immutable record of the currency pair and the forward exchange rate, and
• performing an action based on the comparison result including performing an updated valuation of a contract and sending an alert message;
• and
• concurrently with the updating, comparing and performing an action, performing periodic valuation and transmission of the item having the value that is tied to the transaction data, including:
• transmitting messages to external entities associated with the external identification information,
• establishing transmission links with the external entities including links between respective custodian accounts of the external entities with the transaction and a ledger,
