Problems solved by technology

[0005] However, in the existing technology, only a single node in the consortium chain network is responsible for capturing network evidence and constructing a deposit transaction. When other nodes accept the deposit transaction broadcast by the node, they usually cannot verify the network evidence captured by the node. whether the evidence is true

Embodiment Construction

[0032] figure 1 It is a schematic diagram of the existing mode of accepting blockchain deposit transactions. Such as figure 1 As shown, for the webpage to be deposited, node A can access webpage X and grab a screenshot of webpage X, and then, based on the captured webpage screenshot, node A constructs a certificate deposit transaction including the hash value of the webpage screenshot. Then, on the one hand, node A accepts the deposit transaction (that is, caches the deposit transaction), and on the other hand, broadcasts the deposit transaction to nodes B~D, and nodes B~D also cache the deposit transaction respectively. In the subsequent consensus stage, the cached transaction will be packaged into a block and written into the blockchain by nodes A~D respectively.

[0033] However, in practice, there is such a possibility that node A visits the wrong webpage (does not visit webpage X, but visits webpage Y), or node A intentionally acts maliciously, causing the screenshot of...

Abstract

The invention discloses a method and a system for accepting a blockchain evidence storage transaction. A plurality of nodes (called as evidence obtaining nodes herein) in the block chain network are responsible for capturing network evidences, and after capturing the network evidences, the plurality of evidence obtaining nodes send evidence hashing of the network evidences captured by themselves to each other. And then, each evidence obtaining node determines the evidence hash with the maximum number in all the evidence hashing (including the calculated evidence hash and the evidence hash received by the evidence obtaining node) obtained by the evidence obtaining node as the credible evidence hash, constructs a evidence storage transaction based on the credible evidence hash, and accepts the evidence storage transaction.

Description

technical field [0001] The embodiment of this description relates to the field of information technology, and in particular to a method and system for accepting blockchain certificate deposit transactions. Background technique [0002] With the development of blockchain technology, the business model of realizing network evidence storage based on blockchain is more common. [0003] Specifically, for the network evidence to be stored (such as a web page), generally a node in the blockchain network is responsible for capturing the network evidence, and then, the node will calculate the evidence hash of the captured network evidence, and based on The evidence hash constructs the deposit transaction, and then, on the one hand, the node accepts the deposit transaction constructed by itself, and on the other hand, broadcasts the constructed deposit transaction to other nodes for acceptance. [0004] It should be noted that for each node in the blockchain network, the node accepts...
