  • Patent number: 11954681
    Abstract: A blockchain-enhanced open Internet of Things (IoT) access architecture includes an access point, a number of IoT devices, a hash access mechanism, a blockchain mining network, and a blockchain enabling mechanism that manages network access of the IoT device. The blockchain-enhanced open IoT access architecture provided in the present invention provides a secure, reliable, fair, and short-packet access service for a plurality of devices in an IoT network by using features of a blockchain such as distributed storage, tamper-proofing, and traceability, thereby promoting the trust and cooperation between the devices and ensuring the security and efficiency of the network in the large-scale untrustworthy IoT network. The blockchain-enhanced open IoT access architecture in the present invention can provide secure and reliable IoT access with low latency and a high value in practice.

  • Publication number: 20230327752
    Abstract: The present invention discloses a satellite-based blockchain architecture, including a terrestrial blockchain miner network, a constellation system, and a consensus protocol coordinating the constellation system and the terrestrial blockchain miner network. In each round, a satellite generates an oracle, and satellites broadcast the oracle to the terrestrial blockchain miner network. The oracle selects a terrestrial miner as a winner of the current round based on a specific rule. The winning terrestrial miner has the right to generate a new block in the round, and broadcasts the new block to other miners by using the terrestrial blockchain miner network. Other miners receiving the new block check the validity of the block, and if the check succeeds, the block is broadcast to other miners by using the terrestrial blockchain miner network.
