Abstract

The embodiment of the invention provides an agreement information processing method, device and system based on a block chain and electronic equipment. The method comprises the steps that agreement information (msg) of a to-be-stored certificate is acquired, and the appointment information is generated from application software; a random key (Ai) is generated; the agreement information (msg) is encrypted by using the random key (Ai) to obtain encrypted agreement information; a hash value of the agreement information (msg) is calculated; the hash value of the agreement information (msg) is signed by using a privatekey of a user to obtain signature data; and the encrypted agreement information and the hash value of the agreement information (msg) are uploaded to a block chain.

Description

technical field [0001] The embodiment of the present application relates to the technical field of block chain, in particular to a method, device, system and electronic equipment for processing agreed information based on block chain. Background technique [0002] People often establish various agreements with others in social interaction, whether these agreements are put forward formally or verbally, they have the significance of depositing evidence. As the name implies, deposit evidence, as an agreed witness, can but does not necessarily require it to have legal effect. [0003] At present, there are mainly two agreed deposit methods, one is non-electronic deposit based on traditional media (such as paper), and the other is electronic deposit based on centralized computer storage media. The former is inconvenient for long-term preservation and has the risk of loss, and the latter cannot guarantee that the agreed content of the record will not be maliciously tampered with / ...
