An electronic device is provided. The electronic device includes a communication module, a memory for storing instructions, and a processor, wherein the processor is configured to execute the instructions such that the electronic device identifies owner information of first content in response to a content ownership transfer request, transmits, to a blockchain network, transaction data for transferring the ownership of the first content, on the basis of the owner information of the first content, and transmits the first content to an external electronic device, wherein the transaction data may be regarding a transaction of transferring the ownership of a token related to the first content.

Embodiments of the present specification provide a method, an apparatus, a client terminal, and a server for data processing. The method includes: selecting, based on a data attribute of to-be-processed data, a target coordinating server from a plurality of coordinating servers, the plurality of coordinating servers belonging to a plurality of server clusters respectively; and sending a data processing request to the target coordinating server, such that a server cluster to which the target coordinating server belongs processes the data processing request preferentially, the data processing request directing to the to-be-processed data.

A method for on-behalf ATM processing via blockchain includes: receiving, by a receiver of an automated teller machine (ATM), a transaction identifier; receiving, by an input device interfaced with the ATM, a withdrawal amount; identifying, by the ATM, a blockchain transaction in one of a plurality of blocks comprising a blockchain, wherein the blockchain transaction includes at least the transaction identifier and a current balance; and processing, by the ATM, withdrawal of the withdrawal amount based on the current balance, where processing includes dispensing, by a dispenser interfaced with the ATM, currency equivalent to the withdrawal amount if the withdrawal amount is less than or equal to the current balance or displaying, by a display device interfaced with the ATM, a message indicating an insufficient balance if the withdrawal amount is greater than the current balance.

The present invention generally relates to a method, system and program product for generating a stable value digital asset tied to a blockchain.

This invention relates generally to distributed ledger technology (including blockchain related technologies), particularly a method and corresponding system for providing a blockchain transaction comprising a redeem script for an output that comprises: i) a plurality of public keys, each associated with a corresponding private key, wherein each public key is uniquely associated with a potential state of at least one data source; and ii) logic arranged to provide a result based on: A) a determination of which of the plurality of associated private key(s) is/are used to sign the unlocking script, so as to provide an interim result: and B) a comparison of a parameter supplied via the unlocking script against the interim result, and further attempting to spend the transaction output more than once, each attempt supplying a different parameter.

Methods, apparatus, systems, and computer program products are disclosed for utilizing specially configured machine learning models to generate incremental currency value(s) associated with one or more target merchant data objects. Some embodiments, based on one or more market record sets, identify an actual electronic currency value for a total merchant data object set, and include a counterfactual model configured to generate a counterfactual electronic currency value for use in determining a counterfactual incremental electronic currency impact, and in some embodiments for ranking other models. Embodiments, additionally or alternatively, include an incrementality-trained ensemble model for generating a predictive incremental electronic currency impact. The incrementality-trained ensemble model may be trained to predict based on the rankings of the outputs of the counterfactual model. Embodiments may further rank target merchant data objects and perform one or more additional actions, including assigning the target merchant data objects to sales account data structures for management.

An ecosystem is configured to facilitate digital exchange of digital assets in a digital asset marketplace. The ecosystem includes one or more of a plurality of participant systems selected from a list of participant systems including asset user systems, asset holder systems, and asset mining systems. The ecosystem operates on a computer-executable asset wrapper that is associated with the digital asset and that is configured in the form of a multi-layered structure. The ecosystem also includes a codec that is associated with the asset wrapper and configured as a computer executable file. The codec is executed responsive to a request for an exchange on the marketplace that is associated with the digital asset. The ecosystem further includes a blockchain device to execute a blockchain smart contract for the asset exchange. The blockchain smart contract is executed against a set of right tokens characterizing a specific cryptocurrency value.

An information computer system is provided for securely releasing time-sensitive information to recipients via a blockchain. A submitter submits a document to the system and a blockchain transaction is generated and submitted to the blockchain based on the document (e.g., the document is included as part of the blockchain transaction). An editor may edit the document and an approver may approve the document for release to the recipients. Each modification and/or approval of the document is recorded as a separate transaction on the blockchain where each of the submitter, editor, approver, and recipients interact with the blockchain with corresponding unique digital identifiers—such as private keys.

Systems and methods are provided for generating and managing dynamic customized electronic tokens for electronic device interactions. A system for transferring data between a user device associated with a user and a remote device may include a memory storing instructions and a processor configured to execute the stored instructions. The stored instructions may configure the processor to receive, via a network, transaction information from the remote device, access information associated with an electronic token, and provide the electronic token to the remote device. The electronic token may be associated with at least one of the user or the user device, and a token server may generate the electronic token based on the received transaction information, and determine one or more expiration parameters for the electronic token.

A method for offline transmission of blockchain details includes: storing, in a computing device, a first private key and a currency amount; receiving a first destination address associated with a blockchain network and a transaction amount; generating a second private key; generating a second destination address associated with the blockchain network using the second private key; generating a blockchain transaction including at least the first destination address, the transaction amount, the second destination address, and a remainder amount based on at least the currency amount and the transaction amount; signing the generated blockchain transaction using the first private key; executing a query to replace the first private key with the second private key, wherein replacement of the first private key includes deletion of the first private key from the computing device; and transmitting the generated blockchain transaction.
