Abstract: Methods, systems, and computer storage media are provided for minting non-fungible tokens (NFTs) using one or more location verification devices. For example, a request to mint an NFT may be received from a user device. In embodiments, the request includes an event identifier associated with an event (e.g., a sporting event) and an event location. A public blockchain address can be identified based on the request to mint the NFT. Using location verification data associated with the location verification device, a location of the user device can be verified. For example, location verification data can be associated with at least one signal received from the user device. In some embodiments, the location verification data also corresponds to a user device communication with a base station. Accordingly, the NFT can be minted based on the public blockchain address and verifying the location of the user device.

Abstract: The disclosed technologies include receiving a request from a second computing device to verify ownership of a blockchain address. A challenge content is generated and sent to the requestor. A signature is received comprising a hash of the challenge content generated using a private key. A public key corresponding to the private key is obtained, and the signature is validated using the public key. In response to validating the signature, a characteristic is associated with a user associated with the blockchain address.

Abstract: Technologies are shown for managing stored value on a blockchain involving creating a stored value contract block on a blockchain having an identifier of a first entity and code for transferring a portion of a stored value to a designated party. Funds data is stored to the blockchain indicating the stored value committed to the stored value contract block by the first entity. Code is invoked with an identifier of a second entity to transfer a portion of the stored value to the second entity. Some examples involve an intermediary entity verifying conditions defined in the stored value contract block in order to complete transfer. Other examples involve an intermediary entity monitoring conditions in order to initiate transfer when the conditions are satisfied.
