A composite cryptographic data structure is described, and corresponding methods, systems, and computer readable media. The composite cryptographic data structure is instantiated based on an underlying set of cryptographic tokens (e.g., blockchain/distributed ledger tokens) that, in some embodiments, are transferrable through on-chain transactions established on one or more distributed ledger networks. Identity validation, in some embodiments, may occur at one of composite cryptographic data structure instantiation or composite cryptographic data structure redemption, or both, through the use of a whitelist or a blacklist data structure.

A method of initiating a transaction in a blockchain system includes receiving, by a processing device, biometric data associated with a first party of a transaction to be added to a block of a blockchain system. The method further includes providing the biometric data to a validation node of the blockchain system. The method further includes determining that the biometric data has been validated by the validation node. The method further includes, in response to determining that the biometric data has been validated, recording, by the processing device, the biometric data in the block of the blockchain system.

Systems and methods for verifying a digital title of an asset transferred via a math-based currency transaction. The method includes receiving a digital title request regarding an asset, creating a digital title for the asset in a digital title database, receiving, from a financial institution computing system, an asset transfer request regarding the asset that is the subject of the math-based currency transaction, verifying that an identity of a seller in the math-based currency transaction matches the identity of the owner of the asset. Then, responsive to the verification that the identity of the seller in the math-based currency transaction matches the identity of the owner of the asset, the method includes transmitting, to the financial institution computing system, a positive title verification and updating the identity of the asset of the digital title for the asset to match an identity of a buyer in the math-based currency transaction.

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.

The disclosure relates to a blockchain-implemented system and method of controlling the transmission and/or distribution of digital content. A first user transfers a deposit quantity of cryptocurrency to a common address. A first node associated with the first user: sends a request to the second node to provide an episode of digital content from a series of digital content; determines a payment transaction to transfer a payment quantity of cryptocurrency to the second user based on a quantity of episodes of digital content in the series; and signs and sends the payment transaction to a second node. The second node associated with the second user: receives the request and the payment transaction; verifies the payment transaction; and based on a result of verifying: provides access to the episode of digital content to the first node; and co-signs and sends the payment transaction to a distributed ledger.

A platform implementing a two-tier tokenization process to build a digital asset pool at a server. An application builds the digital asset pool, initializes general asset tokens to represent pro-rata ownership interests in a general pool of assets, and uses general asset tokens to create specific asset tokens to represent ownership interests in specific assets from that pool that a user of the platform selects, from a remote device in communication with the server, from the general pool. General asset tokens offered to eligible retail and/or institutional investors generate funding to build the asset pool. Owners of general asset tokens are periodically offered, by the server, the option to select portions of specific assets from the general asset pool, and create through the two-tier tokenization process, shares of specific asset tokens, subject to the technical protocols, ownership concentration limits, and bidding and allocation schema established by the present platform.

Systems, methods, and techniques for providing blockchain ledger-based authentication for reviews. In one example, a system obtains an identifier associated with an event, generates a contract based on the event, and broadcasts the contract to a blockchain ledger. The contract is fulfilled in response to cryptographically authenticated user input. In another example, a user writes a review, determines conditions for access to the review, and provides the review to a system, in which the system generates a contract based on the review and the conditions, and broadcasts the contract to a blockchain ledger. Viewers can access the review by fulfilling the conditions for access to the review of the contract.

Systems and methods for offering and purchasing tokenized securities on a blockchain platform meeting current and future federal, state, and offering and holding entity rules and regulations. Tokenized securities purchased during or after the tokenized securities offering are tradable on a secondary market. The server computer of the tokenized securities provides an automated transfer capability for tokenized securities holders.

Techniques for integrating a payment processing platform (PPP) and a payment making platform (PMP) for differentiated payment allocations using cryptocurrency is described. The PPP can receive a request to receive funds in cryptocurrency, wherein the funds are associated with transaction(s) conducted via point-of-sale (POS) software provided by the PPP. Based on the request, a cryptocurrency wallet account for the merchant can be accessed via the PMP. The PPP can associate a merchant account of the merchant with the cryptocurrency wallet account. The PPP can receive, via the POS software associated with the merchant, payment authorization request(s) associated with the transaction(s) and cause (i) a first portion of the funds to be deposited as cryptocurrency into the cryptocurrency wallet account and (ii) a second portion of the funds to be deposited as fiat currency into the merchant account.

Systems and methods for digital coin exchange. A digital coin platform receives a distribution request from an entity server comprising digital multimedia content associated with an entity. Digital coins are created responsive to the request. Each digital coin comprises a first coin associated with the entity and a second coin associated with consumers. The first and second coins are linked via linking information. The first coins are transferred to the entity server. A consumption request including the digital multimedia content is transmitted to a consumer device. Responsive to an indication that the content is at least partially consumed via the consumer device, one or more second coins are transferred to the consumer device. The digital coins and the transferred first and second coins are recorded. The transferred second coins permit the consumer device to perform transactions associated with the entity.
