Hybrid blockchain architecture with computing pool

A hybrid blockchain architecture, comprising:

• a hybrid blockchain physical network node;
• an Internet of Things (IoT) blockchain network that is a private blockchain network and is coupled to said hybrid blockchain node;
• and
• a communication blockchain network that is public blockchain network and is coupled to said hybrid blockchain node, wherein said communication blockchain network is selected from an internet network, wifi network, Bluetooth network and telecommunication network;
• wherein a distributed computing pool is built by said communication blockchain network and said Internet of Things (IoT) blockchain network to share a computing capability for a device;
• wherein the hybrid blockchain node broadcasts puzzles obtained for the communication blockchain network to IoT devices in the Internet of Things (IoT) blockchain network, the puzzles are generated by miners of the communication blockchain network, and IoT device of the IoT devices that submits a transaction comprising a correct solution to the puzzles within a predetermined time period is determined to be an authenticated device, and a miner that participates in authenticating the IoT device receives a reward token and records the transaction in a distributed ledger.
