A package management system to initiate a transaction in a blockchain system. The transaction comprises an indication of the signature for the software package and is to be stored in a blockchain. The package management system distributes the software package to a computing device with an indication of a location of the signature in the blockchain.

A content delivery platform may deliver program content segments and advertising content segments to multiple user devices. The content delivery platform may deliver a program content segment to a primary user device of a user for presentation on the primary user device. The content delivery platform may retrieve an advertising content segment from an advertising content store for presentation. The advertising content segment is provided by an advertiser that is sponsoring the presentation of the program content segment on the primary user device. The content delivery platform may send the advertising content segment to a secondary user device of the user for presentation at the secondary user device.

To manage property records using a multi-layered hybrid distributed ledger architecture, identification information for a particular property is obtained and transmitted to at least one participant in a public distributed ledger network for a public distributed ledger layer. Ownership information for the same particular property is obtained and transmitted to at least one participant in a federated distributed ledger network for a federated distributed ledger layer. Transaction-related documents for the same particular property are obtained and transmitted to at least one participant in a private distributed ledger network for a private distributed ledger. The distributed ledger layers are different layers of a property distributed ledger each having a separate set of consensus rules for appending distributed ledger data to the respective layer. This allows for the immutable preservation of royalty terms and conditions for a property or asset using the distributed ledger.

Systems and methods that provide improved security and scalability in digital token exchange are disclosed. In one example, a system may receive from a requester one or more old cryptographically signed tokens each including a shared class and denomination. After validating the previously issued Value Tokens, the system may sign newly issued Value Tokens having the shared class and send them to the requester as a swap for the previously issued Value Tokens. Some tokens have intrinsic value while other coded Value Tokens require reference to a record of valid tokens to validate them. The system allows tokens of one type to be swapped for tokens of the other type, but issues intrinsic Value Tokens only as a swap for coded Value Tokens.

Proxied cross-ledger authentication techniques are disclosed. In various embodiments, a verifier presentation requirement is determined, the verifier presentation requirement indicating a set of elements required to be provided by a client to authenticate the client. An authentication contract instance is created on a market maker ledger not associated specifically with the verifier, the authentication contract instance including at least a subset of the elements required by the verifier presentation requirement. A verifier system associated with the verifier presentation requirement is configured to read information from the authentication contract instance, obtain from an issuer associated with the client an issuer revocation data associated with the authentication contract instance, and use the information read from the authentication contract instance and the issuer revocation data to authenticate the client.

A payment gateway is configured to directly access a revenue stream and financial information about the revenue stream. A machine learning (ML) model is trained to continuously process the financial information about the revenue stream to continuously analyze and score the revenue stream. A smart contract factory is responsive to the scoring by the ML model to generate at least one smart contract on a distributed, decentralized network. The smart contract is programmed to receive payments in stablecoins with respect to revenue stream.

The disclosure describes embodiments of systems, methods, and non-transitory computer readable storage media that increase a base limit value for a contact based on a user interaction with a graphical user interface. Generally, the disclosed system provides a graphical user interface for display to a user that includes base limit increase elements to increase base limit values for contacts of the user. Based on user selection of a base limit increase element, the disclosed system can provide an increased base limit value to an account associated with the contact.

The present invention is a novel system and method for coding, programming and administering a cryptocurrency platform.

Proposed is a blockchain-based virtual currency intermediation and distribution system according to a point return, which can calculate, at a set rate, the amount of return for points that are given or paid offline or online for a user's product purchase or service use, and either convert the calculated amount of point return into a cash currency stepwisely, or convert the calculated amount of point return into a virtual currency recordable on a blockchain according to accumulated points, thereby securing stability and complementarity to support virtual currency transactions.

A first security element is for transmitting an electronic coin data set to a second security element. The electronic coin data set is registered in a coin register of a payment system. The method has the steps of: setting a status of the electronic coin data set from the security element to an inactive status; transmitting the electronic coin data set from the first security element to the second security element; checking whether a receipt confirmation from the second security element has been received in the first security element; and deleting the transmitted electronic coin data set if the checking step results in that the receipt confirmation has been obtained by the first security element. The aforementioned relates to a payment system, a coin register, a security element, and a terminal for transmitting electronic coin data sets.
