  • Publication number: 20240428231
    Abstract: A method for automatic initiation of a blockchain transaction with a pre-approved recipient includes: receiving at least a recipient identifier and a transaction amount; performing a validation process to validate that (i) the recipient identifier is pre-approved by a user of the computing device for blockchain transactions, and (ii) the transaction amount is beneath a predetermined amount limit for blockchain transactions; generating a new blockchain transaction including at least the recipient identifier, the transaction amount, and one or more source addresses; digitally signing the new blockchain transaction using a private key of a first cryptographic key pair stored in a memory of the computing device; and transmitting the digitally signed new blockchain transaction to a blockchain node in a blockchain network.

  • Publication number: 20240414524
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive a cell identifier associated with a neighboring base station. The base station may transmit, to a domain name system (DNS) server, a query constructed based at least in part on reversing a set of bits in the cell identifier. The base station may receive, from the DNS server and based at least in part on the query, an Internet Protocol (IP) address associated with the neighboring base station. Numerous other aspects are described.

  • Publication number: 20240313938
    Abstract: Methods, systems, and devices for wireless communications are described that provide for resource allocation in an integrated access and backhaul (IAB) network. A relay node in an IAB network may be assigned a first resource partition that is different from a second resource partition for the child and parent nodes. Based on a resource configuration (e.g., for a slot) of the second resource partition, the relay node may opportunistically utilize the second resource partition for communications. For instance, the relay node may determine a direction table based on the resource configurations of the child and parent nodes, which may be used to perform uplink or downlink communications in one or more symbols of the second resource partition. The relay node may also identify flexible symbols as free or non-free when determining the direction table.

  • Patent number: 12086802
    Abstract: A method for mediating an atomic swap includes: receiving a swap request from a first computing device including a first address associated with a first blockchain and a network identifier associated with a second blockchain; identifying a second computing device using the network identifier and a second address associated with the second blockchain; generating a proof value and a hashlock using the proof value; transmitting (i) the hashlock and second address to the first computing device, and (ii) the hashlock and first address to the second computing device; verifying a first blockchain transaction on the first blockchain for transfer to the first address, and a second blockchain transaction on the second blockchain for transfer to the second address; and transmitting the proof value to blockchains node associated with the first and second blockchains.

  • Publication number: 20240267990
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio access network (RAN) node may release a radio resource control (RRC) connection of a user equipment (UE). The RAN node may transmit a request to a core network (CN) node to initiate paging for the UE, the request including an identifier of the UE. Numerous other aspects are described.

  • Publication number: 20240104560
    Abstract: Systems and techniques for digitization of payment cards for Web 3.0 (“Web3”) and metaverse transactions are provided. The described systems and techniques allow for the use of non-fungible tokens (NFTs) to represent a payment token for making a payment inside a Web3 and Metaverse environment. Indeed, the described systems and techniques provide a financial NFT enabled representation of a payment card account as a token in a blockchain network, which can then be used to facilitate Web3 payments with real-time fiat to crypto exchanges.

  • Publication number: 20230092733
    Abstract: An access control method comprises: providing access profiles for users, wherein each access profile comprises an access profile identifier and at least one personal identifier mapped to one or more obfuscated payment numbers, and wherein each of the at least one personal identifiers is a non-payment identifier issued by an identity provider; receiving, from a terminal of a service provider, a request to validate permission for a user of a payment device to access a resource made available by the service provider, the request comprising an obfuscated payment number read by the terminal from the payment device; determining whether there is a match of the obfuscated payment number read by the terminal and one of the obfuscated payment numbers of the access profiles; and transmitting at least one of the identifiers of the matched access profile to the service provider for matching to a stored identifier associated with the resource.
