A system, method and computer-readable medium for interfacing with an EMV compliant chip card having an embedded microchip. A transaction computer includes a virtual credit card terminal running in a web browser and that is in communication with an EMV card reader having a chip card slot. The virtual terminal defines a first EMV transaction and a second EMV transaction based upon user input. The virtual terminal then causes the embedded microchip of the EMV chip card to generate a first cryptogram associated with the first transaction and a second cryptogram associated with the second transaction during a contact interface session or a contactless interface session. The virtual terminal then authenticates the first and second cryptograms over a computer network with a card issuer. Once authenticated, the virtual terminal completes the first transaction and the second transaction.

The present disclosure provides a method and a device for control of blockchain data access based on a smart contract. The method includes obtaining, by a blockchain node, an access operation request of an institution, the access operation request including a transaction identifier of a transaction to be accessed, according to the transaction identifier, determining a blockchain state corresponding to the transaction identifier, the blockchain state including a hash value of the transaction corresponding to a last time change of the blockchain state, according to the hash value of the transaction corresponding to the last time change in the blockchain state and an identifier of the institution, performing data access control on the institution, obtaining control result, and transmitting the control result to the institution.

A method for verification of a pruned blockchain transaction includes: receiving, by a receiver of a computing device, a subset of blocks included in a plurality of blocks comprising a blockchain, wherein each block includes one or more blockchain data values; receiving, by the receiver of the computing device, an authentication code; identifying, by a processor of the computing device, a plurality of data chunks in the subset of blocks using the authentication code, where each data chunk of the plurality of data chunks is included in one of the one or more blockchain data values in a block of the subset of blocks; decoding, by the processor of the computing device, a transaction value using at least the identified plurality of data chunks and a fountain code algorithm; and verifying, by the processor of the computing device, the decoded transaction value.

Systems and methods for managing a digital token that represents a real-world item. The systems and methods provide a live video stream to a plurality of user devices, access an interface of an integration system of a tokenization platform that is configured to generate digital tokens, receive an electronic in-stream advertisement from the integration system, present the electronic in-stream advertisement in the live stream, facilitate a transaction by the user for the advertised real-world item and, in response to the user successfully transacting for the advertised real-world item, transmit a request to the integration system requesting that the tokenization platform update ownership data of the advertised digital token.

Systems and methods that generate data representing an analytic result relating to at least one of a state, a workflow, or an event in a digital token system, including a digital token system that cryptographically links a set of digital tokens to instances of a set of real-world entities. The systems and methods produce a behavioral analytic by processing a set of collected data, structuring and filtering the collected data to obtain a multi-dimensional structured data set, and querying the multi-dimensional structured data set. Systems and methods further leverage a set of data collection services configured to collect data from one or more interfaces, a set of workflows configured to produce event data, and a data store configured to store collected attribute data.

Systems and methods for tokenizing real-world items for use in digital commerce are disclosed. In some embodiments, a digital token transaction system configures a set of attributes for a set of digital tokens that are cryptographically linked to a set of virtual representations of a set of items. The set of attributes includes at least one temporal attribute that defines a condition associated with the item for the digital token to become redeemable.
