An Internet of Things (IoT) network includes an IoT device with a communicator to send a communication including egress frame, protocol library builder to determine available protocols, frame analyzer to analyze an ingress frame, and frame builder to build the egress frame from the ingress frame. An IoT network includes an IoT device with network discoverer to identify available parallel communication channels between IoT device and target device, payload, payload fragmenter/packager to fragment the payload into sub-objects for transmission, and packet communicator to send sub-objects to the target device over parallel communication channels. An IoT network includes a plurality of IoT devices, which each include a communication channel to an upstream device, a network link to another one of the plurality of IoT devices, a hash calculator to identify a neighbor IoT device, and a communicator to send out a message to the neighbor IoT device.

An example operation may include one or more of receiving user profile identification data associated with a user profile, creating a smart contract on a blockchain with the user profile identification data, validating an identity of the user profile based on the user profile identification data, performing a predictive analysis by the smart contract to determine one or more future tasks to be performed by a user device associated with the user profile, generating one or more tokens associated with the user profile, the one or more tokens include access rights for the user device to perform the one or more future tasks, and storing the one or more tokens in the blockchain.

In a hosted computing environment a web server receives a document history graph. The web server performs a hash function, providing the document history graph as input to the hash function, the hash function providing a hash value as output. A blockchain services interface in the hosted computing environment generates a blockchain block that includes the hash value in a block payload hash field and the document history graph in a block payload field in the blockchain block. A blockchain consensus manager proposes adding the blockchain block to a private blockchain and receives an indication of consensus A block validator adds the blockchain block to the private blockchain responsive to consensus.

An example operation may include one or more of generating, by a block generator, modified blocks for source ledgers, receiving a merge request to merge a plurality of source ledgers into a merged ledger, identifying the plurality of source ledgers, generating a genesis block from modified blocks of the identified source ledgers, ordering blocks, by a committer node or peer, in the merged ledger based on the genesis block, and validating a block order in the merged ledger.

The present disclosure provides a distributed computer system, which includes a plurality of computing devices. Each computing device includes a memory, a portion of a Blockchain, a transceiver, and a processor. The memory stores a plurality of data transaction requests. Each data transaction request corresponds to a block in the Blockchain and includes a cryptographic hash of a previous block, a timestamp, and transaction data. The transceiver receives a data transaction request from a subset of the plurality of computing devices. The processor determines whether the received data transaction request corresponds to at least one block in the portion of the Blockchain. The processor updates an internal record of the Blockchain, based on determining that the data transaction request corresponds to at least one block in the portion of the Blockchain. The processor then verifies the updated internal record of the Blockchain with a computing device in the subset.

A blockchain creation method and a computing device are disclosed, the method obtains a plurality of first edge computing nodes at a preset first distance from the cloud center, and creates a main chain based on the cloud center and the plurality of first edge computing nodes. At least one first edge computing node is selected from the plurality of first edge computing nodes as a shared edge computing node, and a plurality of second edge computing nodes at a preset second distance are obtained from the shared edge computing node, then creating at least one side chain based on the shared edge computing node and the plurality of second edge computing nodes. A block generated in the at least one side chain is written into the main chain. Data synchronization and security during transmission in the distributed system can be ensured.

An exemplary method includes receiving a request to store a data item within a directory of a virtual file structure layer for an unstructured storage layer of a data storage system, caching an identifier of a collection object representative of the directory, sending a query to a plurality of storage nodes included in a cluster of the data storage system, receiving, in response to the query, replies from a subset of the storage nodes that are available to store the data item, selecting, based on the replies, a storage node from the subset of storage nodes, transmitting the data item to the selected storage node for storage by the selected storage node within the unstructured storage layer, accessing, based on the cached identifier, the collection object, and updating the collection object to include a reference to the data item stored in the selected storage node.

A method of creating, redeeming and transferring tokens associated with tokens on a peer-to-peer distributed ledger. The method includes including metadata associated with the token in a redeem script, wherein the redeem script is associated with a transaction of cryptocurrency on the peer-to-peer distributed ledger. One aspect of the invention provides a method of issuing and/or transferring a token, comprising the steps of generating a blockchain transaction (Tx) having an output (TxO) related to a quantity of cryptocurrency such as Bitcoin, and a hash of a redeem script. The redeem script comprises metadata which in turn comprises a token. The token is a representation of, or a reference to, a tokenised entity. The redeem script also comprises at least one (preferably two or more) public cryptographic keys. The metadata is provided in the redeem script at a location which is designated in the underlying blockchain protocol as a location for a cryptographic key.

A string, identifying an item to be assigned to a physical resource, is hashed to obtain a numeric hash value. The numeric hash value is downscaled to obtain a bucket identifier that identifies a bucket that will hold the numeric hash value. The bucket is then deterministically mapped to a physical resource so that it can be retrieved without accessing a stored data structure representative of the mapping.

The disclosure generally pertains to systems and methods for providing driver alerts inside a neighborhood. In an example embodiment, a neighborhood area network of computers is used to convey to a driver in the neighborhood, a driver alert about a driving impediment present on a road outside a residence. The driving impediment, which may be, for example, a vehicle, a trash receptacle, or an individual, is detected by a detection device (a camera, for example). The detection device informs a computer located in the residence of the driving impediment. The computer then communicates via the neighborhood area network with a computer in the vehicle to alert the driver. In some implementations, information pertaining to driving impediments in the neighborhood may be entered into a distributed ledger by using a blockchain mode of operation. The computer in the vehicle can access the distributed ledger to obtain this information.
