An open electronic commerce system includes a user computing device holding a virtual currency, as a node of a blockchain network; a virtual currency exchange server configured to support virtual currency trading; a point exchange service server configured to determine a reference price parameter from the virtual currency exchange server when there is a request for exchange of the virtual currency that the user computing device holds, and to exchange the virtual currency for a point corresponding to the virtual currency requested to be exchanged; and an electronic commerce server configured to provide support for purchase of an item with the point.

This disclosure relates to transaction systems and particularly to transaction systems of a peer-to-peer nature for digital assets. The asset transfer system may store user, user accounts, and transaction information in associated logic tables within a memory of a server hosting the asset transfer system. Through the use of, but limited to, curl functions, the asset transfer system may communicate with remote servers housing user wallets and user wallet information to perform transactions of digital assets between users. Before verification and proof of work can be established to complete the transfer of digital assets, the asset transfer system may report to the users of a transaction the details of the transaction. Users of the asset transfer system need not know encrypted or random keys to perform such digital asset transactions and may transfer digital assets only by identification of a username stored within the asset transfer system.

A cryptocurrency payments point-of-sale system and method for accepting cryptocurrency as a form of payment is provided. A system and method containing a POS application executed on a smart device for capturing, through a GUI from the POS application displayed on the smart device, payment information in the first type of currency. The POS application generates and displays a QR code. A consumer scans the QR code via a smart device using a digital wallet operating in the second type of currency. Crypto conversion banks coupled to a bank account for the merchant and to the digital wallet from the consumer via the POS application for converting the payment from the second type of currency into the first type of currency, authorizing a transaction and transferring funds from the second type of currency from the digital wallet to the bank account for the merchant in the first type of currency.

A computer-based system converts cryptocurrency into a virtual asset. The system includes a user account database server configured to store data of a plurality of user accounts. The stored data pertains to each user account and indicates an accounting of obligations of the system to the user. The system also includes a cryptocurrency account server configured to receive, from a networked device of a user, a transfer of crypto currency, from an external cryptocurrency account. In response to receipt of such a transfer, the cryptocurrency account server is configured to update the data pertaining to the obligations of the system to the user. The system also includes a user interface server configured to receive a request from the user for conversion of cryptocurrency to an asset. In response to receipt of the request, the system updates the data pertaining to the user account of the user.

A multi-coin mechanism for maintaining a stable value of cryptographic coinage traded in a decentralized market exchange without requiring a reserve. Multiple, pegged cryptographic tokens are traded in the reserveless decentralized market exchange. Each of the multiple, pegged cryptographic tokens may be pegged to a different asset (such as different currencies and/or commodities). The multiple, pegged cryptographic tokens are value related based on cryptographic exchange rates. Whenever a market transaction is processed (such as a buy or sell order), at least one of a destruction operation and a creation operation are performed. The destruction operation destroys at least one of the pegged cryptographic tokens, while the creation operation creates new ones of the pegged cryptographic tokens n. The multi-coin mechanism thus implements a decentralized and algorithmic monetary policy that removes and/or deposits cryptographic tokens to/from the reserveless decentralized market exchange to alter supply and to maintain stable coinage values.

Embodiments relate to methods, systems, devices, and computer readable medium for managing digital assets, such as cryptocurrencies and public key and private key pairs. The method may include forming a first payload (or the owner payload). The first payload may include the public key of the digital asset or a corresponding public address for the public key of the digital asset. The method may also include performing a proof of ownership setup process for an owner of the digital asset. The proof of ownership setup process may include generating a proof of ownership hash. The proof of ownership hash may be generated by hashing at least the first payload. The method may also include signing, using the private key of the digital asset, the proof of ownership hash to arrive at a signed proof of ownership hash.

Implementations of the present disclosure include determining that a private transaction is to be recorded in a distributed ledger system (DLS) based on a consensus protocol executed by a set of entities participating in the DLS, the private transaction including a transaction between a subset of entities of the set of entities, providing a set of noisy transactions based on a transaction model, and transmitting data representative of at least a portion of the private transaction, and data representative of each noisy transaction in the set of noisy transactions for recording in the DLS based on the consensus protocol.

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.

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.

Aspects of the disclosure relate to order processing. A computing platform may determine that order processing for a subset of a plurality of trading pairs should be migrated from a source computing platform to a destination computing platform. The destination computing platform may configure itself to process first trading pair, and may enter a proxy mode where orders for the subset of the plurality of trading pairs are routed to the destination computing platform. The destination computing platform may receive and load order processing information corresponding to the subset of the plurality of trading pairs, and may direct the source computing platform to cease processing for the subset of the plurality of trading pairs. The destination computing platform may disable the proxy for the source computing platform, and may receive orders/process for the subset of the plurality of trading pairs.
