[0090] Based on the first embodiment, a second embodiment of the blockchain-based data storage method of the present invention is proposed. In this embodiment, after step S130, the blockchain data storage method further includes:
[0091] Step S140, when there is a first sub-node server with updated data in each of the sub-node servers, the first sub-node server obtains the updated first data;
[0092]In this embodiment, each sub-node server can monitor in real time whether its own stored data is updated. When there is a first sub-node server for data update in each sub-node server, the first sub-node server obtains the updated first data .
[0093] Step S150, the first sub-node server sends the obtained first data to the main node server;
[0094] Step S160, upon receiving the first data, the master node server stores the first data based on the first identification information of the first sub-node server.
[0095] In this embodiment, when the first sub-node server obtains...

The invention discloses a data storage method based on a block chain. The method comprises the following steps: a master node server sends a first data acquisition request to child node servers; uponreceiving the first data acquisition request, the child node servers feed back currently stored service data of the child node servers; and up receiving the service data fed back by the child node servers, the master node server stores the service data. The invention further discloses a data storage system based on the block chain, and a computer readable storage medium. By adoption of the data storage method disclosed by the invention, all blocks, namely the service data, in a distributed network, only need to be stored in the master node server, and the child node servers do not need to store the service data of other node servers, thereby greatly saving the resources of the child node servers. Moreover, the operating efficiency of application programs related to the distributed networkin the child node servers is improved.
Description
technical field [0001] The present invention relates to the technical field of data storage, in particular to a blockchain-based data storage method, system and computer-readable storage medium. Background technique [0002] The blockchain is a reliable database maintained by a decentralized and trustless collective. The distributed network is the infrastructure of the blockchain. The data generated on each node is broadcast to other nodes through the distributed network, and other nodes pass the workload proof. to verify the authenticity of the data. Distributed network is the premise to ensure the decentralized, non-tamperable, and traceable features of blockchain. In the Bitcoin network, it is precisely because of the verification nodes distributed around the world that the Bitcoin workload proof mechanism is recognized. Only then did people realize the value of the blockchain. [0003] The distributed network is the basis of the blockchain, and each node connected to t...
