Because Douban scoring mechanism isAfter scoring, you can also modify the content and rating, but the number of likes is still there, and the top short reviews with a high number of likes may affect the reputation of the movie, so this loophole was exploited by the water army. Netizens were very dissatisfied with this, and what happened to The Wandering Earth pushed this dissatisfaction to the extreme, so many netizens went to the rating section of the APP store to give Douban a star to express their protest.
Under the strong appeal of netizens, Douban responded on the 12th and announced the revision of the scoring mechanism. Douban said: A large revision of the score is an abnormal score and will not be included in the total score. In order to avoid such incidents, the website is also urgently optimizing product functions. After modifying the rating, the useful (like) data before the modification will be cleared.
In other words, once the rating and content are modified, the number of likes of the short comment will be cleared.
Although Douban has made crisis public relations, this incident is not the first case. Douban has been questioned many times by users and the outside world because of its scoring mechanism.
As an influential platform, Douban has a certain degree of autonomy. The platform itself will not participate too much in the content output by users, and it is more about ruling by doing nothing. This cant help but remind me of the DAO of the blockchain, that is, the decentralized autonomous organization. So can we use blockchain technology to optimize Doubans scoring mechanism?
cannot be tampered withcannot be tampered withIt is one of the characteristics of blockchain. As long as the data is on the chain, it is basically impossible to change the data. This happens to be used in various scoring systems. Take this incident of rating modification as an example. If Douban recorded every movie review and rating in the block, then there would be no five-star to one-star farce. It will not cause an uproar later.
In addition, some users pointed out that Douban has not set a rating threshold, and anyone can comment on Douban. Some people may not have seen the movie, just follow the trend. This problem can also be solved in the blockchain mechanism. The mechanism that everyone can write movie reviews is similar to the mechanism that everyone can participate in miningPOWconsensus. In order to raise the threshold, Douban can learn fromPOS and even DPOS consensus, that is, users need to meet certain conditions to publish movie reviews on the platform, and users may be weighted according to the quality of their past movie reviews.
In addition, Douban can also learn from token economics to build its own token system. Users can get tokens for posting movie reviews, and the obtained tokens can be used to vote for other people’s movie reviews. Movie reviews and users with high votes can become platform nodes (KOL), thereby further improving the quality of platform movie reviews.

Through this incident, we can see that there are actually many potential cases of blockchain landing. In the future, there may really be a public chain dedicated to various voting and scoring, so as to optimize the usability of various comments and truly realize the application of blockchain.
