A transaction system comprises: a terminal device for transmitting, to a server, a remittance request signal for remitting cryptocurrency stored in an electronic wallet; and a transaction server for receiving the remittance request signal from the terminal device, requesting verification of transaction from a blockchain network in order to determine whether the remittance request signal is valid, and remitting the cryptocurrency to an electronic wallet of another terminal device when the remittance request signal is valid as a result of the verification of transaction.

A system and method for digital smart wallet communications that operates by managing separately-owned, private blockchains to reduce processing times, eliminate proof of work burdens, and retain blockchain immutable security while allowing protection of confidential information contained on each blockchain. The system and method may further comprise auditability of blockchains, and may be operated on an integrated communications platform that allows seamless interoperability of communication devices across multiple modes of communication, and automates digital smart wallet transactions.

There is provided a system and method for facilitating automatic customized web feed generation via an aggregator server, the server having a processor, a communication subsystem and a memory each in communication with the processor, the memory storing instructions, which when executed by the processor, configure the aggregator server to: communicate with a plurality of web feed sources to request and retrieve web feeds of a plurality of web sites having web pages; aggregate the web feeds from the plurality of web feed sources and web sites into an aggregated web feed; automatically scan web content of each web page within the aggregated web feed and tag each web page within the aggregated web feed having a pre-defined degree of relevance of information pertaining to at least one pre-defined cryptocurrency to a corresponding at least one cryptocurrency identifier; store mapped sets of each tagged web page and corresponding to least one cryptocurrency identifier in a database of the aggregator server; automatically receive an indication from a computing device of a listing of cryptocurrency assets held by a user of the computing device, said indication indicating an automatic request for web feed information relating to said listing of cryptocurrency assets; automatically provide a custom web feed to the computing device, the custom web feed comprising content from each tagged web page having a corresponding at least one cryptocurrency identifier which exists within the listing of cryptocurrency assets, the custom web feed for subsequent display on the computing device for being associated with the listing of cryptocurrency assets.

A guaranteeing server and a guaranteeing method for transaction on blockchain are disclosed. The guaranteeing server is coupled to a blockchain network and comprises a memory unit and one or more processing units. The memory unit stores a plurality of instructions and the processing units execute the instructions to perform steps of: receiving a transaction data from a user, wherein the transaction data includes a wallet data including a wallet address data and a user's signature data; checking whether a cryptocurrency balance associated with the wallet address data on the blockchain network is sufficient to execute the transaction; when the cryptocurrency balance is sufficient to execute the transaction, transmitting the transaction data to the blockchain network for performing a blockchain operation; and transmitting a transaction guarantee information corresponding to the transaction data to an opposing party of the transaction.

A unified wallet manager (UWM) virtualized as a single virtual service in which all transactions relative to the UWM are treated as immutable facts permanently stored in append-only queues or ledgers from the time of their creation. A rules engine reads conversion requests in request calls to the service, and determines which rule or rules to apply to convert funds from one ledger to another, in the same or different vertically scaled gaming systems. The UWM is a peer of other vertical gaming systems, and the gaming systems access the UWM via an API server and data egresses from the UWM through an ETL process from a database cluster. The immutable queues allow for data reconstruction using any desired data model. The ledger stores funds of many different types, including real money, points, play money, and others. Third parties can integrate with the UWM through an integration hub connected to the UWM.

Systems and methods for facilitating a transaction between a first entity and a second entity using a digital currency are described. In some aspects, a computing node participates in a private distributed ledger for a financial institution and stores one or more transaction blocks representing transactions in a digital currency. The digital currency is issued by the financial institution and is fixed with respect to a fiat currency. The computing node is configured to receive a transaction for transferring an amount of digital currency from a first entity to a second entity, generate a new transaction block representing the transaction, transmit the new transaction block to other computing nodes participating in the private distributed ledger, receive an indication of validity of the new transaction block, and insert the new transaction block into the private distributed ledger.

A computer-implemented method includes: determining assets held by a remitter, the assets to be spent in a remittance transaction between the remitter and one or more payees, in which each asset corresponds to a respective asset identifier, a respective asset amount, and a respective asset commitment value; determining a remitter pseudo public key and a remitter pseudo private key; determining a cover party pseudo public key, in which the cover party pseudo public key is obtained based on asset commitment values of assets held by the cover party; and generating a linkable ring signature for the remittance transaction.

A method and system for predicting a cryptocurrency price using artificial intelligence. The cryptocurrency price prediction method includes the steps of: receiving information on each cryptocurrency from a cryptocurrency exchange server through an API and extracting a plurality of price data, by a data extraction unit; processing and storing the extracted price data in a storage unit, by a data refinement unit; creating a dataset configured of a mean and a standard deviation of each cryptocurrency, by a dataset construction unit; and creating a model using a dataset read function of each cryptocurrency, by a modeling unit.

The subject of the invention is an insurance claim and/or financial transaction processing system for parametric risk related claims and/or performance warranty related transactions that can be processed using transparency and in a rapid manner wherein the performance or insurance is transacted using sensors and/or analytics. The invention also includes a marketplace where parties can enter or leave, buy or sell, a transaction or transactions associated with an insurance or financial transaction. The system enables aggregation and/or distribution of risk, performance obligations or investments, and aggregation/distribution and/or syndication of insurers or bankers, crowdsourcing/crowdfunding and/or participation of individuals and small groups within the transaction system. The integration of investment, insurance risk conditionalities and performance guarantees within a single exchangeable system is also envisioned. Transaction re-risking and de-risking and associated payments or payouts is also envisioned.

The invention provides individual information recording means including: means for recording individual information on the evaluation target in a block chain as a block; evaluation token issuing means for issuing an evaluation token for a commodity/service to be evaluated; and evaluation token storing means for storing the evaluation token issued by the evaluation token issuing means. Accordingly, information recorded and stored by these means can be displayed on a client terminal via each of wallets.
