Embodiment 1

[0048] An embodiment of the present invention provides a blockchain-based storage method. in, figure 1 A structural diagram of a blockchain-based storage system provided by an embodiment of the present invention is shown.

[0049] Such as figure 1 As shown, the blockchain-based storage system 100 at least includes: a data node 110 , a storage node 120 and a mining node 130 . Among them, the data node 110 (also called a participating node) is used to execute the specific steps involved in this scheme; the storage node 120 is responsible for storing all the real information of the blockchain, and is used to execute other steps involved in this scheme and; the mining node 130 is used to generate a new block according to the information to be stored.

[0050] In the storage system 100 provided by the embodiment of the present invention, the number of data nodes 110, storage nodes 120 and mining nodes 130 is at least one, which is not particularly limited in the embodiments of t...

Abstract

The invention provides a storage method, device and system based on a block chain and a storage medium. The method comprises the steps that a data node broadcasts a first broadcast message on a blockchain, the first broadcast message is used for requesting to store to-be-stored information on the block chain, and then the data node obtains a first Merkle tree and a second Merkle tree; wherein thefirst Merkle tree is obtained by the data node according to the to-be-stored information; wherein the second Merkle tree is obtained by the storage node according to the to-be-stored information; therefore, the data node verifies the second Merkle tree by using the first Merkle tree, and if the verification is passed, the data node broadcasts a second broadcast message on a block chain, and the second broadcast message is used for indicating the mining node to generate a new block according to the second Merkle tree. According to the method, the problem of application limitation caused by storage pressure of a block chain-based storage system can be solved to a certain extent.

Description

technical field [0001] The present invention relates to block chain technology, in particular to a block chain-based storage method and device, system and storage medium. Background technique [0002] New application models of computer technologies such as blockchain distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc., are currently widely used. [0003] At present, blockchain technology has been widely used in the field of data storage. In the existing storage solutions based on blockchain technology, the blockchain ledger will completely record the data to be stored broadcast between nodes, that is, blockchain technology meets the storage requirements of massive data. However, this also leads to a huge amount of content in the blockchain ledger, and based on the distributed storage architecture of the blockchain system, each node in the blockchain needs to synchronize the blockchain ledger locally. Each node in the netwo...
