Micro-blog multi-signature method based on chain block

Abstract

The invention relates to a micro-blog multi-signature method based on a chain block. The method comprises the following steps: 1, performing user registration to obtain a pair of public key and private key and an address for transaction and generated by the private key; 2, creating multi-signature addresses by m users by using the addresses obtained in step S1; 3, creating micro-blog sending transaction, and inserting to-be-sent information in the transaction by using an OP-RETURN operator, wherein the OP-RETURN operator is operated by the multi-signature addresses created in step S2, the multi-signature addresses support the authority of n of m; and 4, performing digital signature on the micro-blog transaction by the users onsite in turns, and broadcasting the micro-blog transaction after at least n signatures are obtained, and permanently recording the micro-blog transaction in the block chain after the success of the transaction.

Description

technical field [0001] The invention relates to the technical field of multi-signatures, in particular to a block chain-based microblog multi-signature method. Background technique [0002] With the continuous development of the Internet, people are more and more inclined to online social media, and people are used to using these social media to share their information and status. According to survey statistics, an average of 6,000 new tweets are added to Twitter every second, and the total number of tweets sent every year is almost 200 billion.

AI Technical Summary

Problems solved by technology

[0004] 1) This kind of social media is usually held by a company, and all data is stored in the company's server. All user registration privacy information such as phone numbers, email addresses, etc. will be stored in the server, which is easy hacked

These social media will suddenly push an advertisement, but there is no prompt, and the user experience is particularly bad

[0007] 4) These social media usually require users to register through mobile phone numbers, emails, etc., so as to obtain more information about users. Generally speaking, these companies will model user portraits for these users, but for users, Users just need a platform to obtain and share information, and do not want to expose a lot of privacy

[0010] At present, the blockchain-based Weibo platform has twister, but its functions are relatively simple. It can only be sent by a single person, and it cannot realize the function of multiple people sending Weibo at the same time (for example, for 6 people in a social circle, you can It is required that Weibo can only be sent when at least 3 people sign and confirm)
