Resumen de: WO2026059491A1
Systems and techniques for facilitating microtransactions or micropayments are described. A method includes receiving, at a digicent service on a blockchain, a digital currency microtransaction request to transfer a particular amount of digital currency from a first digicent wallet account to a second digicent wallet account, the microtransaction being a fractional fiat currency transaction. The digicent service verifies the digital currency microtransaction request, including by confirming that a first tokenized payment source (such as tokenized payment card with financial NFT) is associated with the first digicent wallet account and exists as a valid smart contract on the blockchain; and confirming that a second tokenized payment source is associated with the second digicent wallet account and exists as a valid smart contract on the blockchain.

Systems and methods are directed to managing access to a software instance stored on a virtual machine on a blockchain using a smart contract. The system receives, from a client device of a user, an authorization request to access the software instance. The authorization request can include a token associated with the user. In response to receiving the authorization request, the system accesses the smart contract. Based on the token, a determination is made, through the smart contract, whether the user is an owner of a license to the software instance. In response to determining that the user is the owner, a further determination is made, through the smart contract, whether the license has expired without renewal. Based on the license having expired without renewal, the smart contract autonomously triggers the virtual machine to destroy a container comprising the software instance.

In various embodiments, systems and methods for ledger-based cookie management are provided. Rather than store cookie data as text files on the local device drive, cookie data is recorded to a blockchain technology cookie ledger store on a network resource. When a client application (e.g., a browser) on the UE is directed to a cloud-based service, and that cloud-based service calls for access to a cookie, that call is processed by a cookie gateway executing on the UE. The cookie gateway may verify authenticity of the user and generate a cookie access token that it transmits to the cloud-based service. The cloud-based service may use the cookie access token to locate the cookie ledger and access one or more records storing cookie data used by the cloud-based service. The cookie access token may expire upon termination of the session between the user equipment and the cloud-based service.

A system may include a remote server and an on-premises node. The server may receive a first set of parameters defining a blockchain operation. The server may generate an operation payload based on the parameters. The on-premises node may receive the operation payload from the computing server and decode the operation payload to extract a second set of parameters reflected in the operation payload. The on-premises node may compare the second set of parameters to the first set of parameters to determine whether the second set matches the first set. If the parameters match, the on-premises node may sign cryptographically the operation payload and transmit the operation payload to the computing server for the computing server to broadcast the operation payload to a blockchain to carry out the blockchain operation.

This invention relates to an improved method and system for authenticating the travel path of an object using a distributed asynchronous system incorporating blockchain technology and encrypted codes. The system utilizes digitally secured tags containing encrypted logistical data. These tags are physically and digitally associated with the product prior to entering the supply chain. Gateways equipped with artificial intelligence are strategically placed throughout the transportation route, each gateway receiving inputs from any number and type of sensors placed throughout the gateway's physical location. These gateways continuously collect data from their environment and utilize artificial intelligence to create dynamic environmental profiles. These profiles, encapsulated within a cryptographic key, are immutably recorded onto the blockchain ledger associated with the tag device physically associated to a shipment. The distinctive feature of this innovation assures an unalterable record of each shipment's journey, enhancing security, promoting transparency, and enabling swift transmission—and verification—of shipment data.
