According to the announcement of the National Intellectual Property Administration, Tencent Technology (Shenzhen) Co., Ltd. applied for a patent called "Blockchain On-Chain Method, Related Devices and Media", with publication number CN117354324A, and the application date was October 2023. The patent abstract shows that this disclosure provides a method, related devices and media for blockchain on-chain. The method is applied to the first consensus node in the blockchain network, which includes not only the first consensus node but also the second consensus node. The method includes: obtaining multiple batches of transactions to be put on the chain, each batch of transactions to be put on the chain includes multiple transactions of a consensus node in multiple consensus nodes; for each batch of transactions to be put on the chain, packing the transaction indexes of multiple transactions to be put on the chain in the batch of transactions to be put on the chain into a pre-generated block; broadcasting the pre-generated block to the second consensus node, so that the second consensus node can obtain the transactions to be put on the chain based on the transaction indexes and give consensus feedback to the first consensus node based on the obtained multiple transactions to be put on the chain; based on the consensus feedback of the second consensus node, packing the transactions to be put on the chain into the target block to be put on the chain. This disclosure can improve the efficiency of transaction on-chain. This disclosure can be applied to various scenarios such as blockchain, artificial intelligence, and cloud technology.
