Abstract: A method of displaying a multi-layer digital asset in a digital environment includes retrieving, from a digital blockchain ledger, data associated with a first, primary non fungible cryptographic token (NFT) and data associated with a second, sub-asset NFT. The data associated with the first NFT identifies a first retrieval location of a first digital graphics file that is representative of a primary digital asset. The data associated with the second NFT identifies a second retrieval location of a second digital graphics file. The method includes retrieving, the first digital graphics file from the first retrieval location, retrieving the second digital graphics file from the second retrieval location, layering an image from the second digital graphics file onto the primary digital asset to form the multi-layer digital asset, and displaying the multi-layer digital asset in a digital environment.

Abstract: An online store can transmit an online account token to an electronic device or to a biometric sensing device after a user successfully enters his or her account password. The electronic device or the biometric sensing device can countersign the online account token when the one or more biometric images match reference biometric images and the account password matches user identifier data stored in the electronic device or in the biometric sensing device. The countersigned online account token can then be transmitted to the online store. The user can then make one or more purchases after the online store receives the countersigned online account token.

Abstract: This disclosure describes techniques for implementing a blockchain to manage license compatibility. The techniques include parsing a code segment in a version of source code based on one or more parsing parameters, wherein the code segment is associated with a transaction and distributed under a license. Thereafter, one or more blocks are inserted onto a blockchain distributed ledger recording the transaction. Upon receiving an updated version of the source code comprising a change to at least one code segment associated with a new transaction, additional blocks are inserted onto the ledger recording the new transaction. Based at least on the transaction recorded in the blocks, the license associated with the version of the source code is identified. Additionally, a flag may indicate license incompatibility with the license if the change to at least one code segment associated with the new transaction violates a license restriction of the identified license.

The system may invoke from a payment application server a remote EMV payment application based on the EMV payment application URI, wherein in response to being invoked, the remote EMV payment application is configured to interact with a merchant system kernel to process the transaction request, and wherein in response to processing the transaction request the remote EMV payment application is configured to transmit a transaction authorization request comprising EMV transaction data directly to the issuer system.

Abstract: An apparatus including processing circuitry and a method are described. When receiving a cross-chain transaction request to transfer a resource from a first account to a second account, the processing circuitry is configured to generate a task corresponding to the first account. The task can indicate conditions for implementing events in transferring the resource. A first blockchain system provides services for the first account, and a second blockchain system different from the first blockchain system provides services for the second account. The processing circuitry transfers the resource to the second account based on the task when a first plurality of first nodes in the first blockchain system reaches a consensus on a generation event of the task and updates a task status of the task to being finished when a plurality of second nodes in the second blockchain system reaches a consensus on a transfer event of the resource.
