Embodiment approach 1

[0104] Embodiment 1: After each user node extracts evidence files from the storage area (the local storage area of ​​the user node or the storage area docked with the management node), it reports the evaluation elements of the extracted evidence files, or it can be in the verification office After the extracted evidence files have not been tampered with, report the evaluation elements of the evidence files.

Embodiment approach 2

[0105] Embodiment 2: Disclose the evidence file in a read-only manner to each user node that accesses the consortium chain, so that each user node that accesses the consortium chain reports the evaluation elements of the disclosed evidence file.

[0106] In the specific implementation process, the evaluation elements can take many forms, which are explained below:

[0107] Form 1: The evaluation element is the score value of the evidence file. Specifically, the range of the score value can be set, and the user node can score the obtained evidence file within the range of the score value, so that the management node can obtain the evidence file value of each user node. scoring value. For example, the scoring value range can be set to 0-5, or can be set to 0-10, or can be set to 0-100. Of course, the scoring value range can also be set to other ranges according to actual needs. Correspondingly, the preset evaluation condition is the scoring value threshold, and the scoring val...

Abstract

The invention discloses a chain data anchoring method and device, comprising: obtaining the chain time node of the first chain file fingerprint currently written into the alliance chain; judging the time node between the chain time node and the latest anchor time node Whether the preset anchoring time interval is met, where the latest anchoring time node is the corresponding time node when the fingerprint of the second uploaded file is anchored to the public chain set, and the fingerprint of the second uploaded file is on the alliance chain and is the latest Anchor to the fingerprint of the uploaded file of the public chain set; if satisfied, anchor the fingerprint of the first uploaded file to the target public chain of the public chain set. The invention solves the technical problem of insufficient credibility of the evidence chain information on the alliance chain.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to an on-chain data anchoring method and device. Background technique [0002] In the past, in order to store evidence for data, one had to go to a notary office or a judicial authentication institution in person, and only after cumbersome procedures could a legally effective certificate be formed. This process was often carried out offline, the process was complicated, and the time cost was high. timely evidence. [0003] The blockchain is very suitable for evidence preservation. Evidence can be stored on the alliance chain. The alliance chain refers to the blockchain formed by several organizations or institutions jointly participating in the management. The signed evidence chain information will be permanently stored on the alliance chain. As long as any node on the alliance chain has evidence, evidence can be obtained at any time. To tamper with the evidence, it is...
