Various embodiments of the present application are directed towards systems and methods for hybrid blockchain control. According to some embodiments a method for hybrid blockchain control, an update to a distributed blockchain is received from a blockchain system. The blockchain system includes multiple nodes individually storing copies of the distributed blockchain and individually updating the copies by a consensus process. A determination is made as to whether the distributed blockchain has been fraudulently modified based on the received update. In response to determining the distributed blockchain has been fraudulently modified: 1) a corrective block is disseminated to the blockchain system to trigger the consensus process on the nodes; and 2) a predefined override in the consensus process is invoked to update the copies of the distributed blockchain in a manner that bypasses an illegitimate block. Further, the predefined override is invoked while the consensus process processes the corrective block.

The invention relates to hardware and software for data storage and consummation of digital transactions in peer-to-peer environments, primarily for making cryptocurrency payments. The technical result consists in higher security for using a hardware wallet. 3 sub-claims.

A system and method for payment notification using blockchain. The system and method relate to real-time monitoring and updating of a list of accounts that have not satisfied a minimum payment amount due. The real-time monitoring and updating of the list occurs through the use of a blockchain monitoring payment information by a user to the account. The blockchain is continually updated every time a payment is made. A notification system receives each update and is aware, in real-time, whether a user has satisfied a minimum payment amount due and thus whether an account is current or in need of a collections notification.

A smart contract including one or more rules is defined and stored in a distributed ledger in conjunction with a pool of one or more tokens owned by the smart contract. A plurality of conflicting claims to the pool of one or more tokens is received and provided to the distributed ledger. An indication that a trigger condition is met is received from the distributed ledger. The trigger condition to determined using the one or more rules. Information indicating a distribution of the one or more tokens to resolve the plurality of conflicting claims is also received. The information is generated using the one or more rules in response to the trigger condition being met.

A method for trading a non-fungible token (NFT) among a plurality of blockchains includes minting an NFT based on digital content at a first blockchain, transferring the NFT to a second blockchain, trading the NFT between the second blockchain and a third blockchain, which is incompatible with the first blockchain, and recording the trade in the second blockchain.

Embodiments relate to systems, apparatuses, and methods for performing transaction signing utilizing asymmetric cryptography and a private ledger. A transaction data is signed by a user device using a private key, and may be utilized in an authorization request message without including a real credential of the user. A transaction verification and accounting module (TVAM) can verify the signed transaction data and can continue processing the transaction.

A system and method for handling crypto-asset transactions includes: receiving from a payment processing system an electronic transaction request including: a payment token corresponding to a payment identifier associated with the customer account, and a transaction amount in a fiat currency; determining current price data corresponding to a first crypto-asset and a second crypto-asset associated with the customer account; associating the electronic transaction request with at least one data processing task for executing at least one crypto-asset transaction; and when at least one crypto-asset confidence condition is satisfied based on the current price data of at least one of the first crypto-asset or the second crypto-asset, generating signals for providing, via the payment processing system, an indication that the electronic transaction request is authorized without waiting for confirmation of execution of the at least one crypto-asset transaction in the respective distributed ledger.

Described herein is a system for generating a master token to be associated with a set of tokens. In some embodiments, a number of tokens may be obtained by a communication device, which may be provided to a primary authorization computer. The primary authorization computer may generate a master token to be associated with each of those tokens. When the master token is used to complete a transaction, an authorization request may be received by the primary authorization computer that includes the master token. Upon receiving this, the primary authorization computer may obtain approval from a number of secondary authorization computers associated with the tokens, and may generate an authorization response based on those approvals.

A data aggregation and process automation (DAPA) system is disclosed. The DAPA system includes an authentication module, a monitoring module, an intelligent automation module, and a transformation module. The authentication module is configured to initiate authenticated communication with a plurality of servers, and includes an authentication storage having a plurality of authentication credentials and routing information. The monitoring module is configured to monitor a first server for a first change event and monitor a second server for a second change event. The first change event results in the receipt of a first data object and the second change event results in the receipt of a second data object. The intelligent automation module is configured to identify the second server, request a service, and submit an update data object to the first server. The transformation module is configured to transform data objects from one format into another.

Methods and systems for use in a blockchain network are presented. A method comprises: associating identification information with a private key or with a custodian of the private key, wherein the identification information enables initiation or execution of one or more distributed ledger-based computing operations in the blockchain network; accessing, by at least one first computing device in the blockchain network or at least one second computing device in the blockchain network, an issuance digital facilitator for facilitating the initiation or execution of the one or more distributed ledger-based computing operations in the blockchain network, the one or more distributed ledger-based computing operations in the blockchain network involving the at least one first computing device or the at least one second computing device; and connecting the identification information associated with the private key or the custodian of the private key, to the one or more distributed ledger-based computing operations.
