A sensor blockchain system is provided. The sensor blockchain system includes a plurality of sensor-data-loggers, wherein each sensor-data-logger includes a memory device which utilizes FN tunneling. An input to the sensing interface alters the geometry of the energy barrier to change the electron leakage rate and the current state of the sensor-data logger is determined by an initial state of the sensor-data-logger, the predetermined electron leakage rate, and any inputs to the sensing interface. The sensor-data-loggers may be synchronized to an initial state. The synchronization will be maintained when they are all subjected to similar changes in environmental conditions in a supply chain. Desynchronization will occur due to changes in environment, including changes in temperature.

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.

A cryptographic method and system. A plurality of ciphers is identified in a message received by a recipient, such message encrypting a digital asset. A private key associated with the recipient is obtained. The private key corresponds to a public key associated with the recipient. The method includes solving for x in the equation: [(f.sub.0(R.sub.0.sup.−1 N′.sub.0 mod S)+P′+f.sub.λ(R.sub.n.sup.−1 N′.sub.n mod S))/(h.sub.0(R.sub.0.sup.−1 N′.sub.0 mod S)+Q′+h.sub.λ(R.sub.n.sup.−1 N′.sub.n mod S))]*h(x)−f(x)=0 mod p, where (i) P′, Q′, N′.sub.0, and N′.sub.n correspond to the ciphers in the received message; (ii) R.sub.0, R.sub.n and S are data elements of the private key; (iii) f(.Math.) is a polynomial function defined by coefficients f.sub.0, f.sub.1, . . . f.sub.λ that are also data elements of the private key; and (iv) h( ) is a polynomial function defined by coefficients h.sub.0, h.sub.1, . . . h.sub.λ that are also data elements of the private key. The value of x is assigned to the digital asset, which is then stored in non-transitory memory or packaged in a message sent over the data network.

Generating a verifiable pairwise claim. Receiving a request for issuing a verifiable claim that is associated with a subject entity and is verifiable by one or more verifying entities. The request includes at least an encrypted portion using a particular type of encryptography. Verifying that the subject entity is associated with a subject of the verifiable claim based on decrypting the encrypted portion using the particular type of cryptography. In response to verifying that the subject entity is associated with the subject of the verifiable claim, issuing the verifiable claim that is structured to be verifiable only by the one or more verifying entities.

The present invention relates to a system and a method for performing exchanges of digital data records among a plurality of distributed databases. More specifically, the present invention relates to a technology agnostic atomic swap system platform configured to perform atomic swap transactions of digital data records among a plurality of distributed ledger technology platforms.

A method of managing an overlay network overlaid on data-storage transactions of a blockchain, whereby data content of the overlay network is stored in payloads of the data-storage transactions and overlay-layer links are defined between the data-storage transactions. The method comprises identifying a graph structure of the overlay network, wherein nodes corresponds to different ones of the data-storage transactions and edges correspond to the links. Each node is associated with a respective first key for signing an input of a child data-storage transaction to authorise writing the child to the blockchain. The method further comprises using a child key derivation, CKD, function to determine a hierarchical set of second keys having the same graph structure as the overlay network, wherein the second keys enable an additional function other than signing inputs of the data-storage transactions.

A system for assigning value to a digital asset is disclosed. In some embodiments, the system is configured to link the monetary valuation for a digital asset to a sport team's performance. In some embodiments, the monetary valuation for a digital asset associated with a sport team can increase or decrease based on historical performance or live performance. In some embodiments, the system includes a dashboard that displays various sport teams and the value of associated digital assets. In some embodiments, the system includes functionality that allows a user to buy, sell, and/or trade digital assets associated with a sports team. In some embodiments, the system includes a digital wallet configured to store the digital asset and/or a crypto key that enables access to the digital asset on a blockchain. In some embodiments, the digital asset is a digital token or a digital coin.

System and method are described for creating and validating identities across multiple blockchains. According to an embodiment, a system uses decentralized resources to receive an enrollment request comprising entity information to create a multi-chain identity of an entity and create an account with a global identifier for the entity and one or more decentralized identities (DIDs), each associated with a cryptographic blockchain of a set of supported cryptographic blockchains. The system maintains a mapping of the global identifier and the one or more DIDs created, share the global identifier and the one or more decentralized identities in a digital wallet associated with the entity. In an embodiment, the digital wallet is implemented as an application to be run on a computing device associated with the entity. The digital wallet stores the global identifier, the one or more decentralized identities, and corresponding cryptographic keypairs associated with each of the one or more DIDs.

A method comprising: receiving an input tensor having a shape defined by [n.sub.1, ...,n.sub.k], where k is equal to a number of dimensions that characterize the input tensor; receiving tile tensor metadata comprising: a tile tensor shape defined by [t.sub.1, ..., t.sub.k], and information indicative of an interleaving stride to be applied with respect to each dimension of the tile tensor; constructing an output tensor comprising a plurality of the tile tensors, by applying a packing algorithm which maps each element of the input tensor to at least one slot location of one of the plurality of tile tensors, based on the tile tensor shape and the interleaving stride, wherein the interleaving stride results in non-contiguous mapping of the elements of the input tensor, such that each of the tile tensors includes a subset of the elements of the input tensor which are spaced within the input tensor according to the interleaving stride.

A federated-data-room server manages information about a collection of electronic documents residing elsewhere (under different organizational/customer control). The server can anchor documents to a blockchain, record usage history of each document, and provide access to the documents for authorized users. As a result, the federated-data-room server operates on customers' data, while leaving the data in control of the customers. At the same time, the federated-data-room server provides data access and enables traceability via blockchain recordation of document identifiers and document hash values.
