In general terms, embodiments of the present invention relate to methods and apparatuses for providing a service for exceeding account thresholds via a transaction machine. For example, in some embodiments, a method is provided that includes: (a) receiving transaction information associated with a transaction, where the transaction involves an account, a transaction machine, and a holder of the account; (b) determining, based at least partially on the transaction information, that the account will incur an exceeded threshold as a result of the transaction; (c) prompting, via the transaction machine, the holder to consent to the exceeded threshold; (d) receiving the holder's consent to the exceeded threshold; and (e) authorizing the transaction based at least partially on the receiving the holder's consent.

Methods and an associated system for end-to-end secured payments between users and other users or merchants, using only touch gestures and with no exchange of payment identifiers, credentials, or authorization codes include 1) a computer-implemented method for end-to-end secured payments between users and other users or merchants, using only touch gestures and with no entry, storage, nor exchange of regulated payment system identifiers, credentials, or authorization codes; 2) a non-transitory computer readable storage medium encoded with programming for end-to-end secured payments between users and other users or merchants using only touch gestures, with no entry, storage, nor exchange of regulated payment system identifiers, credentials, or authorization codes; and 3) a system for end-to-end secured payments between users and other users or merchants using only touch gestures, with no entry, storage, nor exchange of regulated payment system identifiers, credentials, or authorization codes.

Disclosed are a digital currency transaction method, apparatus and electronic device, and a computer-readable medium. The method includes: receiving a transaction request, and acquiring feature negotiation information from a hardware carrier of the digital currency wallet; determining a transaction type on a basis of the feature negotiation information; acquiring a deduction amount corresponding to the transaction request, and generating an interoperability-based transaction request on a basis of the deduction amount and the feature negotiation information in response to determining that the transaction type is an interoperability-based transaction; sending the interoperability-based transaction request to an interoperability platform, so as to invoke a corresponding operator interface by means of the interoperability platform to send the interoperability-based transaction request to a corresponding digital currency operator; and receiving deduction information generated after the digital currency operator executes deduction on a basis of the interoperability-based transaction request, and outputting the deduction information.

An example operation may include one or more of generating a unique image based on execution of an image generating model and displaying the unique image via a user interface of a software application, assigning a segment of the unique image to a goal at a first point in time based on user inputs via a user interface of the software application, monitoring account activity of a user within the software application, determining, at a second point in time, that the user is closer to the goal based on the monitored account activity of the user within the software application, and in response to the determination, increasing a size of the segment of the unique image assigned to the goal of the user.

A computer-implemented method to participate in a token transfer process for transferring a first quantity of token from a sender node to a recipient node using a blockchain is disclosed. The token transfer process includes a plurality of participating nodes and execution of a set of indirect token transactions between multiple pairs of the participating nodes. The method is implemented at a participating node and includes: obtaining a subset of the set of indirect token transactions, the subset including only those transactions for which the participating node is either an input node or an output node, wherein the set of indirect token transactions is generated based on the first quantity of tokens and a predefined number of transaction rounds in the token transfer process; for each indirect token transaction in the subset, collaborating with a respective second participating node included in the indirect token transaction to generate a commitment channel for the indirect token transaction between the participating node and the second participating node; and collaborating with all other participating nodes in executing the indirect token transactions of the subset using the generated commitment channels.

A method includes receiving, from a source user account associated with a source digital wallet of a source blockchain, a request to perform a cross-chain operation from the source blockchain to a destination blockchain. The source blockchain is associated with a source token contract that stores a delta value indicative of a difference between a total number of tokens having an attribution property in circulation of the source blockchain and a number of tokens having the attribution property in circulation of the source blockchain that are accounted for by a vault of a primary blockchain. The attribution property identifies a token issuer. The method further includes causing a cross-chain message including a transaction payload to be generated based at least in part on the delta value, and causing the transaction payload to be applied to the destination blockchain.

A system and corresponding method, for blockchain cryptocurrency exchange, track at least one pending blockchain transaction on a corresponding blockchain. The at least one pending blockchain transaction has been executed, but not yet committed, on the corresponding blockchain. The system and corresponding method determine whether an unexecuted blockchain transaction for cryptocurrency exchange is valid or invalid as a function of transaction information associated with the unexecuted blockchain transaction and the at least one pending blockchain transaction. The system and corresponding method output a result indicating whether the unexecuted blockchain transaction was determined to be valid or invalid, causing the unexecuted blockchain transaction to be executed or denied, respectively.

A computer-implemented method to participate in a token transfer process for transferring a first quantity of token from a sender node to a recipient node using a blockchain is disclosed. The method comprising: joining a token transfer process as a participating node in the indirect anonymous transfer protocol; obtaining a list of indirect token transactions for which the first node is either an input node or an output node for in the indirect anonymous transfer protocol; generating, in collaboration with other participating nodes of the indirect anonymous transfer protocol, a commitment channel between the first node and each of the other participating nodes for which an indirect token transaction identified in the list obtained by the first node, and collaborating with all the other participating nodes and executing the indirect token transactions in which the first node is involved, using the generated commitment channels.

Systems and methods are disclosed for selectively increasing and decreasing the balances of gaming accounts and stored value accounts. Each of the gaming account and the stored value account are associated with a player. Instructions for balance transfers can be provided by the player to a remote computing device.

The present disclosure involves systems, software, and computer implemented methods for providing rapid approval of blockchain-based transactions. This includes approval of transactions prior to the transaction being written to the blockchain. A transaction system can register with a transaction manager, such as a cloud-based or cloud transaction manager, which can maintain a queue of pending transactions and provide approval for transactions in real-time or near real-time, while later verifying the pending transactions are written into the blockchain as expected. This allows the transaction system to securely confirm the transaction is approved prior to the transaction being written in the blockchain, based on a real-time or near real-time analysis of each customer's corresponding account and transactions.
