A method comprises receiving from a distributed app (dApp), a shard creation transaction in a blockchain block of a blockchain, the block comprising multiple shards; collecting, with a join block in the blockchain, transactions, the join block adjacent the blockchain block; encapsulating the shard creation transaction; applying the block including the shard creation transaction to yield a new shard in the block; and broadcasting the block.

Blockchain sharding with parallel threads

A computer-implement method comprises: selecting a trusted computing node via smart contract on a blockchain; completing remote attestation of the selected trusted computing node; writing secret information to an enclave of the selected node; causing a thin device to establish a private connection with the selected node without revealing the secret information; and causing the selected node to act as a proxy on the blockchain for the device. Another method comprises: receiving a signed device access request from a device owner; validating, by the verification node, the received request; executing, by a verification node, a smart contract on a blockchain based on the received request; and producing, based on the executed smart contract, an output command to access the device for the device to validate, decrypt and execute.

Blockchain joining for a limited processing capability device and device access security

A method comprises receiving from a distributed app (dApp), a shard creation transaction in a blockchain block of a blockchain. he block may comprise multiple shards. Next, the method comprises collecting, with a join block in the blockchain, transactions. The join block is adjacent to the blockchain block. Next, the method includes encapsulating the shard creation transaction; applying the block including the shard creation transaction to yield a new shard in the block; and broadcasting the block. The join block executes cross shard transactions without impacting the parallel execution of intra-shard transactions with computer threads by separating inter-shard and intra-shard transactions into different blocks. Without join block, parallel executing intra shard threads in computer threads may need to lock the database states since inter-shard transactions may also write to it from different computer thread. Not sure if we need to make this clear in our claims regarding join block.

A method, a system, and an apparatus provide for a cable modem termination system (CMTS). The CMTS may include a virtual machine configured to provide a plurality of virtual CMTSs (vCMTSs). The CMTS may also include a plurality of subscriber groups. Each subscriber group of the plurality of subscriber groups may be assigned to a vCMTS of the plurality of vCMTSs. Additionally, each vCMTS is configured to provide a process.

Virtual cable modem termination system

Techniques are generally directed to selective reestablishment of Internet Protocol (IP) connectivity between a cable modem and a cable modem termination system (CMTS). IP connectivity between the cable modem and the CMTS is initially established through execution of a plurality of connectivity steps. After IP connectivity is lost, the cable modem determines which of the plurality of connectivity steps are desired for use in reestablishing IP connectivity, and sends a message to the CMTS indicating the desired IP connectivity step. The CMTS determines if the desired connectivity steps identified in the message may be used to reestablish IP connectivity, and sends a response message to the cable modem indicating if the desired connectivity steps may be used. IP connectivity is then reestablished using at least the desired connectivity steps.
