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.

Abstract: An improved gossip-protocol-based method, a device, a piece of equipment and a medium for incentivizing block propagation. By improving the Gossip protocol and embedding block propagation rewards, the block forwarding process is accelerated. The designed signature chain structure records the block forwarding path and ensures that the path information is not tampered with. By combining the signature chain structure with the block generation process, the rewards are ensured to be truly and reliably distributed. A block propagation reward distribution strategy is designed to prevent forwarding nodes from adding pseudonyms in the propagation path. Therefore, the method can reduce the blockchain stale rate and enhance the scalability and consensus performance of the blockchain by accelerating block propagation in the presence of selfish nodes, and addresses the problem that selfish nodes refuse to forward blocks to save communication consumptions in the current blockchain network.

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. The present invention significantly improves the efficiency and throughput of a blockchain, and optimizes and reduces the energy consumption of executing a consensus protocol by a terrestrial blockchain miner network.
