How much do you know about the future “blockchain Google?”

Recently, the editor appeared on Twitter, facebook, Telegramd and other major media websites and on the big screen of Reuters outdoor advertising, that is QTC, so the editor started the human flesh search of QTC, and finally revealed QTC’s information.

Mystery, today I will make a simple science popularization for you all.

Looking back at our own lives today and the world today, since the emergence of Bitcoin and blockchain, we seem to have a little more inexplicable courage for many things that we are accustomed to today, to question and even try to correct them.

Search engines are one such example. I saw a discussion on hacker news today. Someone wrote a paper and proposed to create an open web index to solve the problems faced by search engines today.

This question seems a little strange. For ordinary users, the search results are fast enough, and they can basically find everything they want. What else is not satisfied?

With this question and the spirit and thinking of blockchain, we approach QTC together:

1. What is QTC?

QTC is based IPFS distributed search engine designed to block the chain to become “Google” and resolve personal data privacy issues, not controlled by any company or individual, the search engine back to the people.

It is a tool based on blockchain distributed ledger technology used to search encrypted data stored on different nodes on the blockchain. Each node of QTC can choose other search algorithms according to its situation. When searching for the information we need, please search for a keyword on QTC, and the search engine on each node will query in its distributed ledger. All results are output, and the search details will also be encrypted and stored in the distributed ledger. At the same time, QTC is also an essential part of Web3.0 data value conversion. It builds a truly peer-to-peer market between data producers, service providers, and potential consumers without intermediaries to make price differences, reduce market friction, and give full play to the market. Come with potential.

2. The significance and value of QTC

QTC has solved some of the problems that traditional search engines have troubled the public to some extent.

First, QTC is based on different network nodes to store data, and users do not have to worry about information loss.

Second, QTC will list all the results in the distributed node according to the keywords searched by the user, with no ad insertion in the middle, significantly improving the efficiency of the search.

Finally, QTC adopted encryption technology. The user has their private data key unless the individual will inform others; otherwise, the individual can completely control their data information, not stolen by others, significantly ensuring users’ privacy.

QTC can give the public a real solution to the problem and let more people really participate in it and achieve an excellent ecological cycle.
