Using blockchain technology in the Internet of Things (IoT) security is a research trend in recent years. With large IoT networks, miners will have to verify a lot of transactions broadcast from IoT devices. This can cause a delay in saving valid transactions to the ledger. This paper proposes a proof-of-miner-clustering-authentication consensus method of blockchain for IoT networks. In the proposed method, miners in a blockchain network will be clustered, each miner in a cluster is responsible for verifying transactions from IoT devices in the area it manages. Mining of new blocks between clusters is done by the round robin method. Our consensus method can apply to private or consortium blockchain networks, helping to improve the transaction verification speed of miners.
