Comments and vote properties of existing website is a centralized, has the following features:
1. The site administrators have delete, modify the content of concern, support against the number of audience data such as power, so the credibility of this site is insufficient,
2. User sensitive comments will causing the site to be blocked, and from long-term accumulation of website content resources will be wiped out,
3. The user needs the system to the relevant comments,
I have a vision, to think in block chain to design a review site, achieve the following goals:
1, review content, user behavior data cannot be tampered with
2. Users hold a copy of the content, not afraid of websites blocked
3. Can realize the user information encryption,
Don't know whether use block chain technology can achieve the above goals???????
CodePudding user response:
As far as I know, if used for study, the project can be implemented, if the project into a commercial, for the moment is not suitable for large scale application,In fact we have idea to do last year WeChat decentralization, public comments, taobao, today's headlines, etc., using block value chain change transfer mode, to build credibility and so on, bala bala,
Commercial or test for more than half a year, but there is a problem, finally making the integration of industry resources alliance chain block chain,
Block chain chain ring is developed so slowly, or content type block chain no outbreak, because the data of non real-name, rather than the real name and to achieve a balance between government regulation, at present does not apply to ordinary people, or chain,
But for the voting system, that is not a problem, because the vote itself is anonymous, but you asked for ordinary users have a copy of the content, this is where the male chain, male chains currently is not suitable for business;
2 it is chain packing the block is no longer a user's access speed and frequency dimensions, COINS pack a block for 10 minutes, now the fastest block chain packing hundreds of thousands of times a second (see online, there is no real hammer), but the taobao, there may be ten million times a second deal, because the block chain zhang to check the time consuming, trading, the more the more serious the network congestion, the disadvantages of this block chain are born to bring,
Your three requirements: (1) the data cannot be tampered with, this is the block chain; (2) a copy of the user has to block chain is the chain; (3) the user information encryption, block chain's own,
So if you're just learning, and it is the application layer, directly based on Ethernet fang DAPP can make a vote,
If is the underlying development study, such as the Java language development, database storage can use RocksDB; Using the ellipse encryption, such as dense + bouncycastle SM2 countries; Network can be used to build a DHT Netty structure P2P network; Consensus algorithm, Raft is the most simple, but suitable for private chain, if is chain can choose POW (but I won't concrete implementation), choose PBFT league chain; In view of the rewards and punishment mechanism in the public chain, who charge to an account, who have certain interests, finally use block chain top together, finally again on the ground floor to an interface, it is the application layer,
CodePudding user response:
It's not reasonable to meaningless, at least for now,CodePudding user response:
1, the content on the chain do not tamper with the easy to do2, the chain is more books on content, if the data volume is larger, can use IPFS + extracted data hash
3, user information encryption, if refers to the real name or information such as mobile phones, so can go to central data such as telecom identity out after ok
You say other sensitive information, legal compliance is the first article, circle are ok, but the circle may not insist on block chain,
And the understanding of the public are not necessarily correct, is to vote much are not necessarily suitable for leave against is not suitable for or not correct,
So people think this scene is not too fit, have this idea, it is better to go to think about how for taobao comments I do,
How to find a third party, reduce the weight of I, let the product and the seller's credit real value, the more lucrative than you,
Buyers comments, to authorize the APP at the same time, on the part of the data chain or IPFS storage, how to incentive to use,
