An apparatus, computer-readable medium, and computer-implemented method for configuring computing systems to facilitate decentralized asset management for individual assets and composite assets such as funds. Implementations include smart contract interfaces to link fungible tokens to non-fungible asset tokens to decouple securities transaction logic and corporate functions from asset management to facilitate code reuse. Additionally, the embodied process uses token nesting to enable homogeneous or heterogeneous assets to be combined into a fund structure, and further for funds to be composed into fund of fund models. The flexible structure enables automation of fund management and is designed to facilitate broad investor access to innovative asset management strategies that leverage the disclosed structure.

A method for facilitating foreign transactions through inter-currency exchanges and geographical matching includes providing a platform to consumers located in different countries, where a consumer in a first country that desires a product from a second country is matched to a consumer in the second country that desires a product in the first country; the consumers are matched and transactions initiated by the platform to provide transfer of any necessary payment to ensure that each consumer can make the purchase on behalf of the other consumer in their own country, for shipping to the consumer in the other country, negating the need for the consumers to make any international purchases directly while still availing themselves of foreign products without involving merchants and minimizing the effect and amount of cross-border transactions.

A cryptocurrency system of the present disclosure employs one or more creator computing devices, one or more initial transaction computing devices, one or more asset-backed computing devices, one or more certifier computing devices, and one or more block chain verifier computing devices. In operation, the system enables a person or legal entity to create and manage electronic currency that is backed by assets.

A payer transaction device enables secure offline transactions using a secure element providing a secure payer account database, a secure ledger database, and a wallet application. While the payer transaction device is not connected to the Internet, the wallet application receives a payee identifier and a transaction amount and verifies that the transaction amount is less than an available payer account balance in the secure payer account database. In response, the wallet application creates a digital token that allocates the transaction amount from the payer account balance to the payee identifier, and records the digital token in a payer secure ledger in the secure ledger database, which reduces the available payer account balance by the transaction amount. The wallet application then transfers the digital token to a payee transaction device over a peer-to-peer wireless connection and, subsequently, the digital token is synchronized with a ledger tracking system through the Internet.

Embodiments include methods and systems for linking high-value tokens using a low-value token, comprising receiving, from an electronic data server, a first high-value token and a request for a low-value token, the first high-value token being associated with sensitive data associated with a user, and the low-value token being associated with a subset of the sensitive data associated with the user. The methods and systems further comprise providing the low-value token to the electronic data server, and receiving, from a second electronic data server, the low-value token and a request for a second high-value token, the low-value token having been provided to the second electronic data server by the electronic data server. The methods and systems further comprise generating a second high-value token associated with the sensitive data associated with the user, and providing the second high-value token to the second electronic data server.

Methods and apparatus for utilising a distributed ledger, such as the Ethereum blockchain, to monitor and execute a process instance (170) between parties that may not trust each other. The proposed methods and apparatus integrate blockchain into the choreography of processes in such a way that no central authority is needed, but trust maintained. The combination of a set of components (a translator 160, a process instance 170 and a trigger/interface 120, 130) allows for monitoring or coordination of business processes on the blockchain (150) and off the blockchain (140).

Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing parallel execution of transactions in a blockchain network. One method includes receiving multiple transactions; for each of the multiple transactions, pre-executing the transaction and determining accounts affected by the pre-executing the transaction; performing a consensus process of the multiple transactions and the accounts affected by the pre-executing the transaction; dividing the multiple transactions into groups of transactions based on the accounts affected by the pre-executing the transaction; executing the groups of transactions in parallel; and in response to determining that, for one of the multiple transactions, accounts affected by the executing the transaction are the same as the accounts affected by the pre-executing the transaction and the accounts affected by the executing the transaction are not affected by any previously executed transactions in the multiple transactions, committing the executing the transaction.

The instant disclosure illustrates how the privacy and security of activities occurring on distributed ledger-based networks (DLNs) can be enhanced with the use of zero-knowledge proofs (ZKPs) that can be used to verify the validity of at least some aspects of the activities without private information related to the activities necessarily being revealed publicly. Methods and systems that are directed at facilitating the tracking and recovery of assets stolen on ZKP-enabled DLNs while preserving the confidentiality of the tokens are presented herein.

Methods and systems for automatically conducting a continuous forward rate agreement in a cryptocurrency using smart contracts. An obligation object is generated and provided with control of a first smart contract, which may be a collateralized debt position smart contract, and control of a lender amount. The obligation object is executed to update balances for first and second parties until the obligation object is liquidated or terminated. Additional parties may be introduced. Upon liquidation or termination, the obligation object accounts to each of the parties based on their balances, and based on tokens generated to track positions in the obligation object.

A method for facilitating selection, by a healthcare facility, of a physician from a plurality of physicians to provide interpretation of an imaging study, is provided. The method includes receiving physician credentials from at least one physician, receiving, from the healthcare facility, an imaging study and a request for interpretation of the imaging study, the request including physician selection criteria, providing access to the imaging study and the request for interpretation to qualified physicians whose credentials match the physician selection criteria, receiving an interpretation of the imaging study from those qualified physicians that have accepted the request for interpretation, comparing the physician credentials to the physician selection criteria, and selecting an imaging study interpretation from the received imaging study interpretations based on the comparing of the physician credentials to the physician selection criteria.
