Data representing ownership of a traditional asset of a first party having a predefined monetary value stored at a first party network node is replicated to a plurality of other party network nodes, including a second party network node, communicably coupled to the first party network node and to one another. Entry of data is received at the first party network node that represents a partition by the first party of the asset of the first party on a non-value axis into at least two non-overlapping assets and a transfer of ownership of one of those two assets to the second party. The data representing the partition of the non-value axis and transfer of ownership of one of the two non-overlapping assets to the second party is replicated to the plurality of other party nodes, including the second party network node.

Methods, systems, storage media for authentication are described. On the methods includes receiving, at a smart contract on a distributed ledger, a signed authentication challenge. The method includes verifying the identity of the user who signed authentication challenge. The method includes raising an event that indicates that the user has been authenticated; wherein a server listens for events from the smart contract, and associates a session between the browser and the server with the user based on the event.

A method for the verification and authentication of additive manufactured product, comprising the steps of receiving, from a customer, at least one customer requirement for a product, deriving at least one manufacturing requirement and generating a product geometry file for the product, recording, by a first computing device, to a distributed transaction register, a first transaction reflecting certification of the product geometry file, obtaining a first output reflecting the first transaction, printing the product with a 3D printer, recording, by a second computing device, to the distributed transaction register, a second transaction reflecting the printing of the product and the first output, obtaining a second output reflecting the second transaction, embedding within the product a unique code reflecting the second output, whereby the product geometry file and the printing of said product may be verified with the unique code such that the product may be authenticated.

A system may receive a request for user data associated with a user account, transmit the user data in response to the request, and receive an authorization request for a transaction from a merchant device. The authorization request may include transaction data and an item identifier. The system may also approve the transaction in response to a user account having sufficient funds available and store the transaction data and the item identifier in association with the user account.

Embodiments of the invention are directed to methods, apparatuses, computer-readable media, and systems for securely processing remote transactions. One embodiment is directed to a method of processing a remote transaction initiated by a communication device. The method comprising a server computer receiving a payment request including encrypted payment information that is encrypted using a first key. The encrypted payment information including security information. The method further comprises decrypting the encrypted payment information using a second key, obtaining an authentication response value for the remote transaction from an authentication computer associated with an issuer, updating the decrypted payment information to include the authentication response value, re-encrypting the decrypted payment information using a third key, and sending a payment response including the re-encrypted payment information to a transaction processor. The transaction processor decrypting the re-encrypted payment information using a fourth key and initiating a payment transaction using the decrypted payment information.

A pre-certified payment application driver code configured to satisfy requirements of a particular level of a credit card data security certification compliance may be integrated with first and second POS applications to generate first and second integrated applications, respectively, as a fully integrated, tested and production-ready solution. Each integrated application meets all levels of data security compliance requirements and enables data security-compliant transactions with end-to-end encryptions by enabling, in response to a POS application initiating a payment transaction, a payment terminal to share an encryption key with a payment server. Each integrated application can receive payment data encrypted with the encryption key, transmit the encrypted payment data to the payment server for processing the payment transaction using the encrypted payment data, and receive a processing result of the payment transaction from the payment server and communicate the processing result to the POS application.

A secure method for exchanging entities via a blockchain is presented. The method comprises receiving, from a user over a communications network, an invitation to perform an exchange of entities; generating a redeem script comprising metadata; hashing the redeem script to generate a redeem script hash; sending the first script and the first script hash on a distributed hash table (DHT); and generating an invitation transaction comprising an output associated with an encrypted digital asset, and a hash of a script comprising an indication of entities to be exchanged, conditions for the exchange, and a public cryptographic key associated with the user.

Provided herein is a computer-implemented method, a system, and a non-transitory computer-readable storage medium. The system may be implemented using a blockchain network. The computer-implemented method includes: i) attaching a digital asset of a first entity to an exchange platform; ii) computing a first shared key associated with the digital asset using a key of the first entity and a first key of the exchange platform; iii) generating and broadcasting a first blockchain transaction to a blockchain network; and iv) initiating, by the first entity, transfer of ownership of the digital asset from a first entity to a second entity; v) computing a second key and a second shared key; vi) replacing the first key associated with the exchange platform with the second key associated with the exchange platform; and vii) detaching, by the second entity, the deposit from the exchange platform using the second shared key.

There may be provided a computer-implemented method. It may be implemented using a blockchain such as, for example, the Bitcoin blockchain. The computer-implemented method includes: i) joining a congress by transferring, by a node operating in a proof-of-work blockchain network, one or more digital assets to a congress pool having one or more other digital assets associated with other members of a congress; ii) detecting, by the node, a special transaction of digital assets on the proof-of-work blockchain network to an address associated with the congress pool, the special transaction satisfying determined criteria; and iii) minting, by the node, one or more digital assets on a proof-of-stake blockchain network in response to detecting the special transaction.

A high-performance distributed ledger and transaction computing network fabric over which large numbers of transactions (involving the transformation, conversion or transfer of information or value) are processed concurrently in a scalable, reliable, secure and efficient manner. In one embodiment, the computing network fabric or “core” is configured to support a distributed blockchain network that organizes data in a manner that allows communication, processing and storage of blocks of the chain to be performed concurrently, with little synchronization, at very high performance and low latency, even when the transactions themselves originate from distant sources. This data organization relies on segmenting a transaction space within autonomous but cooperating computing nodes that are configured as a processing mesh. Each computing node typically is functionally-equivalent to all other nodes in the core. The nodes operate on blocks independently from one another while still maintaining a consistent and logically-complete view of the blockchain as a whole. According to another feature, secure transaction processing is facilitated by storing cryptographic key materials in secure and trusted computing environments associated with the computing nodes to facilitate construction of trust chains for transaction requests and their associated responses.
