A physical card (in some cases without any on-board source of power or computing capabilities) is configured to maintain access information for digital bearer assets. A unique identifier visible on the card may be transmitted to a server-system to utilize functionalities corresponding to the card (e.g., based on information associated with the unique identifier) on a decentralized computing platform, like a blockchain-based decentralized computing platform. Private access information, like a secret, private key that corresponds to a public key (e.g., a public-private key-pair) or a representation of the private key (like a ciphertext thereof) and corresponding encryption key, may be physically concealed with tamper-evident components such that a user can readily determine whether the private access information was divulged. In some examples, a user is required to activate one or more tamper-evident features, thereby altering a visible state of the card, to utilize functionalities corresponding to the card.

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 the orchestration of variable lending repayment terms using cryptocurrency collateral.

Methods and systems are disclosed for transactions with a private digital currency. The private e-currency may be backed by a financial institution, managed using a blockchain, and only available for transactions with members of a network associated with the financial institution. The members may include mobile wallets, merchants and ATM's. A mobile wallet may register with the network and receive an amount of the private e-currency from the financial institution. The mobile wallet may establish a connection with a payment recipient such as another wallet, an ATM or a merchant, and receive a payee address. The mobile wallet may send a transaction request to the blockchain for payment to the payee address of a payment amount of the private e-currency, so that the payment recipient can, using a blockchain, confirm or deny the transaction request.

A system and method for data aggregation and process automation is disclosed. The method includes receiving a first data object from a first integration point through a first smart adapter, identifying an appropriate rules library from a plurality of rules libraries using a rules engine, the appropriate rules library being identified using the first data object, and applying the appropriate rules library through the rules engine. The rules are applied by instructing a transformation module to transform the first data object into a transformed data object, instructing a validation module to validate at least one of the first data object and the transformed data object, and instructing an aggregation module to perform a statistical analysis on one of the first data object and the transformed data object. Finally, the method includes sending the transformed data object to a second integration point associated with a second smart adapter.

A method and corresponding system is presented for controlling a blockchain transaction output and/or specifying the recipient of the output. It also provides a method of controlling and/or generating an electronic communication. The unlocking script is provided in order to spend an output from a further transaction (Tx.sub.2) on the blockchain. The input of the transaction (Tx.sub.1) and/or the output of the further transaction (Tx.sub.2) may be associated with a tokenised asset represented on, or referenced via, the blockchain. The notification address may be associated with an asset or resource represented on the blockchain, or a controller of an asset or resource represented on the blockchain. The notification address may be a network address, a cryptographic key, a uniform resource locator (URI), email address or any other address or identifier which can be represented in the metadata of a transaction script and used as a destination for an electronic communication.

The present disclosure generally relates to an application program in an ICD on the user device that is actually a real-time, double entry, biometrics-activated interactive ledger system for payment and other transactions. The ePassbook is a digital cash payment system that would approximate or even be better than real cash payment in terms of efficiency, cost, convenience, security, and service. The ePassbook is a ledger system in the ICD on the user's device that shall enable the opening of prepaid accounts, make transactions, check credit cards, debit cards, and account balances, etc. on a user device, for example, a smartphone. The ePassbook allows a buyer to initiate a payment transaction upon selection of a payment method displayed on the first user device via the ledger A or, accept the payment by a receiver or a merchant via the second ledger/ledger B on the second user device. The ePassbook is a real-time biometrics-activated double-entry and interactive ledger system in the ICD on the user's device that is connected to and is part of a broader real time double entry and interactive general ledger system that resides in a server.

An electronic device receives, from a user, a restriction that restricts how sound of a digital asset plays to non-owners of the digital asset that is tokenized as a non-fungible token (NFT). One or more electronic devices tokenize the digital asset as the NFT on a blockchain that stores the restriction how the sound of the digital asset plays to the non-owners of the NFT.

The present disclosure relates to systems, methods, and non-transitory computer readable storage media for implementing a scalable, secure, efficient, and adaptable distributed digital ledger transaction network. Indeed, the disclosed systems can reduce storage and processing requirements, improve security of implementing computing devices and underlying digital assets, accommodate a wide variety of different digital programs (or “smart contracts”), and scale to accommodate billions of users and associated digital transactions. For example, the disclosed systems can utilize a host of features that improve storage, account/address management, digital transaction execution, consensus, and synchronization processes. The disclosed systems can also utilize a new programming language that improves efficiency and security of the distributed digital ledger transaction network.

A computer implemented method of a receiving secure computing component to provide access to a cryptographic key for a key requester, the key being associated with an owning secure computing component by a digitally signed record in a blockchain wherein the blockchain is accessible via a network and includes a plurality of records validated by miner computing components, wherein the key requester has associated a quantity of cryptocurrency by a digitally signed record in the blockchain, the method including: receiving a request from the key requester to access the key; generating a first new record for storage in the blockchain to transfer a predetermined quantity of cryptocurrency associated with the requester to be associated with the receiving component, the first new record being validated by the miner components; responsive to the validation of the first new record, communicating a request to the owning component to transfer the key to the receiving component; responsive to securely receiving the key at the receiving component and a validation of a second new record in the blockchain, the second new record associating the key with the receiving component, providing the requester with secure access to the key.

Techniques for allocating investment deposits are described. A user can request that investment deposits to an existing account be allocated between investment accounts associated with the user's investment portfolio. The investment accounts can be of different asset classes (e.g., cryptocurrency, securities, commercial paper, fiat currency, non-fiat currency, etc.). The particular allocation amounts and/or percentages can be based on a machine-trained model.
