A non-fungible token (NFT) document platform includes a host platform that is operable to create and/or perform one or more transactions related to one or more NFTs on behalf of and/or for one or more other entities. Creation of the NFTs may involve creation of one or more smart contracts, storage of the smart contracts and/or the NFTs in one or more blockchains, and so on. The NFT document platform may also be operable to mint one or more documents, such as one or more birth certificates, contracts and other signed documents, titles, prescriptions, licenses and/or identification documents, checks, money, gift cards, and so on. The smart contracts and/or NFTs may correspond to the one or more minted documents. The NFTs may be usable to authenticate the minted documents, evidence ownership of the minted documents, control the ability to perform transactions regarding the minted documents, and so on.

A method of incentivizing a consumer to share data useful for ad targeting includes providing a mobile application with a dedicated digital keyboard and an integrated blockchain wallet; collecting first person data typed into the keyboard according to a smart contract; storing the data on a data storage medium; and rewarding the consumer for sharing the data. A system for incentivizing the consumer to share the data includes a mobile computing device having a processor and a memory. A mobile application resident on the memory includes a keyboard graphical interface integrated with a smart contract dashboard and a cryptocurrency wallet address. The consumer can generate a passive income. The keyboard system can replace cookies as a method of obtaining 1st party data for advertisers.

Embodiments provided a distributed computer system and a method of managing one or more non-fungible tokens (NFTs) using a mobile wallet system that is hosted using a mobile computing device. Various embodiments support using a Mobile Wallet Pass to represent a digital token and its utility outside of Web3 and/or Blockchain systems, software, or context; digitally linking an anonymous, unique digital token to an anonymous, unique Mobile Wallet Pass; de-linking and expiring the Mobile Wallet Pass when the original digital token is transferred from one Crypto-Wallet to another; communicating with token-holders via mobile-phone based push notifications that are presented on the Mobile Wallet Pass; manifesting the utilities of the digital token in relevant contexts using the Mobile Wallet Pass; enabling the token-holder to provide Personally Identifiable Information to the token-issuer using the Mobile Wallet Pass and claim additional utilities from the token-issuer; applying segmentation to digital tokens and presenting different utilities via the Mobile Wallet Pass; unlocking a utility based on their Web2 identity using the Mobile Wallet Pass.

Systems and methods are provided for processing global CBDC transactions in a blockchain supported network, where domestic and foreign banking institutions may provide mutual hosting of a consortium blockchain to allow more seamless and direct CBDC supported transactions, and CBDC exchanges in real-time or near-real time.

An apparatus in one embodiment comprises a processing platform having at least one processing device. The processing platform implements a trusted bridge configured for at least temporary coupling between one or more data sources and a smart contract program of a blockchain. The trusted bridge comprises a secure enclave component and a relay component. Data obtained from a given one of the data sources via the relay component of the trusted bridge is authenticated in the secure enclave component of the trusted bridge. Information based at least in part on the data authenticated in the secure enclave component of the trusted bridge is provided to the smart contract program of the blockchain via the relay component of the trusted bridge. The secure enclave component illustratively receives a request for authenticated data from the blockchain smart contract program via the relay component, and responds to the request via the relay component.

A method for establishing connection weights between network nodes is implemented by communicating data processing units, a public key and a private key being associated with each node, a given node being able to communicate its public key to another node, thus forming a so-called real connection (IRL-connected) between two nodes, and each node also being able to communicate to another node a public key received from yet another node, thus forming a so-called indirect connection between the other node and the yet another node. Each node can have a specific connection weight in relation to another node with which it has a real or indirect connection. In order to determine the connection weight of a second node in relation to a first node, the method comprises calculating a set combination of weighting factors (influence, proximity) of third nodes that are IRL-connected to the second node.

A crypto ETP is administered by a portfolio modeling computer/(PMC), a fund administration computer/(FAC), an order taking platform computer/(OTP), a custodian computer/(CC), and a paying agent settlement computer/(PASC). The PMC defines the ETP and captures data for a cryptocurrency index. The CC tracks Underlying Assets held by the ETP, and sends the data to the FAC, which calculates the NAV of the Underlying Assets to generate a Portfolio Composite File/(PCF) sent to the OTP. The OTP receives and validates/confirms with the CC, orders for creations and redemptions of the ETP from Authorized Parties/(APs), in exchange for the Underlying Assets and/or cryptocurrency. The PASC provides settlement on the Exchange in cryptocurrency by: receiving confirmation from the CC of transfer of underlyings, ETPs or cryptocurrency from the APs to a blockchain wallet associated with the PCM; and issuing units of the ETPs, underlyings or cryptocurrency to the APs.

Systems and methods are provided to mitigate flaring of natural gas. A natural gas processing system may process raw natural gas into a fuel gas stream that may be used to power any number of on-site power generation modules. In turn, the power generation modules may convert the fuel gas stream into an electrical output, which may be employed to power any number of distributed computing units housed within one or more mobile data centers. In certain embodiments, the distributed computing units may be adapted to mine cryptocurrency or perform other distributed computing tasks to generate revenue.

A digital currency payment method and system, and an apparatus, a security chip, and an application method, which relate to the technical field of computers. The payment method includes: generating a transaction amount, or acquiring, by means of a communication connection between a first client and a second client, the transaction amount sent by the second client; and sending a payment request to the second client by means of the communication connection, where the payment request indicates a first digital currency corresponding to the transaction amount or a circulation identifier of the first digital currency, so as to enable a second currency management apparatus corresponding to the second client to cash a second digital currency corresponding to the transaction amount to a first currency management apparatus corresponding to the first client.
