Embodiment 1

[0048] The embodiment of the present invention provides a blockchain-based certificate storage method.

[0049] Please refer to figure 1 , figure 1 A structural diagram of the certificate storage system provided by the embodiment of the present invention is shown.

[0050] Such as figure 1 As shown, the blockchain-based certificate storage system 100 at least includes: a data node 110 , a storage node 120 and a mining node 130 . Among them, the storage node 120 is used to store the original file of the certificate information, and to perform other steps involved in this solution; and the data node 110 (also called a participating node) is used to store the certificate information The original file of the certificate information is stored in the storage node 120, and used to perform other steps involved in this solution; the mining node 130 is used to generate a new block according to the certificate information.

[0051] In different application scenarios, such as figure ...

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 stores storage information to a storage node, and then the data node obtains a first Merkle tree and a second Merkle tree; Wherein the first Merkle tree is obtained by the data node according to the storage information; wherein the second Merkle tree is obtained by the storage node according to the storage information; Therefore, the data node verifies the second Merkle tree by using the first Merkle tree, if the verification is passed, the data node broadcasts a first broadcast message on a block chain, and the first broadcast message is used for indicating the mining node to generate a new block according to the second Merkle tree. According to the method provided by the invention, the problem that the application of the block chain-based evidence storage system is limited due to the storage pressure 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 certificate 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 applied in the field of data storage. In the proof storage scheme based on blockchain technology, each requested proof document will be fully recorded in the blockchain ledger, that is, blockchain technology meets the demand for massive data storage. 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 network causes a larg...
