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.

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.

Methods, systems, and apparatus for risk mitigation for a cryptoasset custodial system include transmitting an endorsement request for a cryptoasset transaction to a user device configured to cause the user device to prompt a user to endorse the cryptoasset transaction. Multiple data points are collected from mobile devices associated with the user. The data points indicate an identity of the user. A cryptographic endorsement of the cryptoasset transaction is received from the user device. A graphical visualization including a risk metric is generated based on the data points. The risk metric indicates a risk of accepting the cryptographic endorsement from the user device. Generating the graphical visualization includes determining whether the plurality of data points matches expected values.

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.

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.

Described herein are various methods of sharing data across multiple computers. The method of sharing data permits the pruning of data from the shared data.

A method and system and computer program product for subscribing to action plans including a processing device for receiving an action plan transaction message having one or more data fields from an analyst node in a blockchain network and generating an action plan transaction in a blockchain including the one or more data fields of the action plan transaction message and a newly generated plan identification. The processing device may transmit an action plan notice to the blockchain network alerting the nodes of the blockchain network of the action plan transaction. The processing device may receive one or more client bids for the action plan transaction, determine a winning client bid of the one or more client bids, generate a winning bid transaction in the blockchain and transmit a winning bid notification to the client node of the winning client bid.

A content delivery platform may deliver program content segments and advertising content segments to multiple user devices. The content delivery platform may deliver a program content segment to a primary user device of a user for presentation on the primary user device. The content delivery platform may retrieve an advertising content segment from an advertising content store for presentation. The advertising content segment is provided by an advertiser that is sponsoring the presentation of the program content segment on the primary user device. The content delivery platform may send the advertising content segment to a secondary user device of the user for presentation at the secondary user device.
