Some implementations of the disclosure are directed to receiving, at an authentication server system, a distributed ledger address transmitted by a client device to identify itself during an authentication process for accessing a network, where the distributed ledger address corresponds to a distributed ledger network; transmitting an authentication challenge message from the authentication server to the client device; in response to transmitting the authentication challenge message from the authentication server to the client device, receiving at the authentication server, a response to the challenge message including a signature; and using at least the distributed ledger network to determine if the signature used to sign the response to the challenge message is associated with the distributed ledger address transmitted by the client device.

An example operation includes one or more of solving, by a scheduler node, integer programming problem of maximizing a sum of organizations' endorsing peers that run chaincodes from a plurality of chaincodes within a consortium, making, by the scheduler node, endorsement policies (EPs) for the chaincodes from the plurality of the chaincodes to be satisfiable at any time, applying administrator's constraint of available endorsing peers to the maximized sum of organizations' endorsing peers, and adding resulting endorsing peers to a maintenance list.

A method and a device for managing access authorization to a payment service provided to a user is disclosed. A request to initialize at least one access authorization is received from a terminal of the owner user. Such an access authorization is intended to allow at least one delegated user to access the account of the owner user, the request comprising at least one identifier of the delegated user and one identifier of the owner user. Temporary data for accessing an account associated with the delegated user is generated, the temporary data comprising a public identifier associated with the delegated user, and a confidential code associated with the public identifier. The temporary data is transmitted to at least one terminal of the delegated user or of another user.

The present disclosure describes transaction-enabling systems and methods. A system can include a facility including a core task including a customer relevant output and a controller. The controller may include a facility description circuit to interpret a plurality of historical facility parameter values and corresponding facility outcome values and a facility prediction circuit to operate an adaptive learning system, wherein the adaptive learning system is configured to train a facility production predictor in response to the historical facility parameter values and the corresponding outcome values. The facility description circuit also interprets a plurality of present state facility parameter values, wherein the trained facility production predictor determines a customer contact indicator in response to the plurality of present state facility parameter values and a customer notification circuit provides a notification to a customer in response.

Various aspects of the disclosure relate to automated compliance verification systems for authenticating and verifying compliance associated with electronic transactions. A compliance verification platform may be an intermediary between an application for managing and/or recording transactions and a transaction processing platform for processing a transaction. Based on successful compliance verification and authentication, the compliance verification platform may send notifications to the transaction processing platform to process a transaction requested via the application

A method, apparatus, and system of activating and using a contactless card are disclosed. A method includes receiving a transaction card application for a contactless transaction card from an applicant; issuing a contactless transaction card based on the transaction card application, wherein the contactless transaction card comprises a uniform resource locator (URL) embedded thereon; and activating the contactless transaction card in response to receiving information from a contactless communication between the contactless transaction card and a customer device, wherein the contactless communication causes access to a web site associated with the URL.

A system, method, and apparatus for decentralized e-commerce and related transactions are provided. A computing system is configured to generate buyer and seller digital wallets on a distributed ledger, receive listings for products sales from a seller electronic device, display listings for sale, and receive requests to purchase any of the listings from a buyer electronic device. A computing system is configured to chain a new block of data to a previous block of related data each time an inquiry, transaction, or other interaction with data contained with a digital wallet, such as currency or product or service listings, are received. The computing system is further operative to authenticate, display, and even translate communications transmitted and received by and between buyer/seller user electronic devices.

A computer-implemented method, non-transitory, computer-readable medium, and computer-implemented system are provided for deploying a smart contract in a blockchain network. The computer-implemented method includes: receiving, by a blockchain node in a blockchain network, a transaction for creating a smart contract, wherein the transaction comprises machine codes of the smart contract, and the machine codes of the smart contract are obtained by a compilation service provider performing Ahead of Time (AoT) compilation on bytecodes of the smart contract; determining, by the blockchain node, that the machine codes of the smart contract are obtained by a trusted compilation service provider; and in response to determining that the machine codes of the smart contract are obtained by the trusted compilation service provider, completing, by the blockchain node, a deployment of the smart contract.

An integration system for a system of platforms includes an orchestration platform, a blockchain transactional platform, a digital transactional platform, a merchant system, a user trust platform, and one or more user devices connected to each other and a distributed ledger and/or a secondary mesh network via one or more networks. The blockchain transactional platform performs accesses and performs actions on the distributed ledger and/or the secondary mesh network. The digital transactional platform maintains transactional data indicative of an amount of first-domain value correlated to a user. The blockchain transactional platform maintains blockchain transactional data indicative of an amount of second-domain value correlated to the user. The orchestration platform manages data exchange, synthesis, fusion, analysis, and transformation between the components of the system, including for the orchestration of transactions.

A system and method including receiving input data from a plurality of Data Sellers, selling tokens to a plurality of Data Buyers, receiving tokens from a first Data Buyer in exchange for providing data and analyses calculated from input data received from one or more Data Sellers, paying tokens to the each Data Seller whose data was used to calculate the data and analyses provided to the first Data Buyer, and trading tokens between token buyers and token sellers.
