    摘要: A system described herein may receive a request to bridge an asset from a first distributed ledger to a second distributed ledger. The system may record, to the first distributed ledger, information indicating that the asset is frozen. The first distributed ledger may maintain information indicating that the frozen asset remains associated with an owner of the asset. The system may record, to the second distributed ledger, a bridged version of the asset, and may link the asset to the bridged asset. The system may identify a transfer of the bridged version of the asset to a second owner, and record, to the first distributed ledger and based on the linking of the asset to the bridged asset, information disassociating the first owner from the asset.

    摘要: A network device receives a smart contract for permissions to access a service, wherein the smart contract is in an initial block for authorizations in a shared ledger. The network device receives, from an authorization server device, an update to the shared ledger, wherein the update is a proposed block in the shared ledger requiring validation. The network device stores, in a local memory, a copy of the shared ledger with the update, when the update is validated by the distributed consensus network. The network device receives, from a client device, an item request for an item associated with the service, wherein the item request includes a client identifier. The network device identifies if there is match of the client identifier and the item in the copy of the shared ledger and sends, to the client device, the item when there is match of the client identifier and the item.

    摘要: A system described herein may provide a technique for bridging an asset, such as a non-fungible asset (e.g., a Non-Fungible Token (“NFT”)) from one blockchain to another, while retaining the uniqueness and/or scarcity of the asset. The system may receive provenance information associated with the asset that is associated with a first blockchain, associate the particular asset with a particular identifier, and receive an instruction to bridge the asset to a second blockchain (e.g., from an owner of the asset). Based on receiving the instruction to bridge the asset to the second blockchain, the system may lock the asset on the first blockchain, and mint the asset on the second blockchain, wherein the minted asset includes the particular identifier. The identifier may be linked to off-chain data that associates the minted asset to the original asset, thus maintaining the chain of custody of the asset across the two blockchains.

    摘要: A device determines, based on location verification data that has been received, that the device is indoors at a first geographic location. The device determines a base measured barometric pressure, and an initial floor that the device is located on in a structure that includes the first geographic location. The device determines an adjusted measured barometric pressure for a second geographic location based on a second measured barometric pressure for the second geographic location and one or more reference barometric pressures that are associated with a reference location. The device determines an altitude for the second geographic location based on the base measured barometric pressure and the adjusted measured barometric pressures. The device causes a server to predict a floor that the device is located on at the second geographic location and to provide floor data that identifies the floor to an interface that is accessible to the device.

    摘要: A microservice node can include a network real-time kinematics (RTK) device to receive raw satellite data associated with a physical reference station via a first message in a first message queue, to receive static virtual location data associated with a static virtual reference station (VRS) agent, to generate corrections data for the static VRS agent based on the raw satellite data and the static virtual location data, and to transmit the corrections data to the static VRS agent. The microservice node can include the static VRS agent to publish the corrections data in a second message in a second message queue. The microservice node can include an adapter device to determine that the client device is located within a geographic area associated with the static VRS agent and to transmit the corrections data from the second message queue to the client device.

    摘要: Systems and methods described herein securely compute private data on a cloud platform. A network device in the cloud platform obtains a product or service description from a first user. The description includes a combination of public data and encrypted private data based on a first encryption key. The network device receives a query from an end device of a second user and retrieves, based on the query, the product or service description. The network device forwards the description to a trusted execution environment (TEE) instance for decryption of the encrypted private data, processing of the private data, and re-encryption of the private data with a second encryption key. The network device receives the re-encrypted private data from the TEE instance and assembles the re-encrypted private data and the public data into a query response for presentation on the end device. The network device sends, to the end device, the query response including the re-encrypted private data and the public data.
