The revolution in blockchain and decentralized computing has brought a world of possibilities to the world. And a technology that may come to be decentralized and that is present in the daily life of any internet user are search engines such as Google, DuckDuckGo and Baidu. Would it really be possible for a decentralized search engine to become as popular as Google?
Although Google has represented a significant evolution for internet users, making it much easier to find what you want on the world wide web, many people fear that so much power is concentrated in the hand of a single company. To give you an idea, the market value of Alphabet, a conglomerate that owns Google, is more than 2x higher than Argentina's GDP.
With that in mind, many users look, whenever they can, for alternative companies just to try to minimally boycott the technology giant. But now, a competitor worthy of Google may not be another company, but a decentralized application, check out an example.
Presearch
Presearch is a decentralized search engine that was born in the 2017 ICO boom and emerged with the stated objective of reducing the power concentrated in the hands of a few internet searchers. 
Privacy
Searches performed on the platform do not record your search history. Queries "are handled by a decentralized network of node servers that process searches anonymously".
Rewards
It is possible to receive reward tokens when researching, operating a node and referring others to join the platform.
Advertising model
Advertisers can bet their tokens (PRE) on a keyword and the advertiser who bets more tokens will have their advertisements displayed when a user searches for the selected term.
Decentralized governance
According to the project's whitepaper, the idea is to create a decentralized governance network, allowing token holders to decide “through a democratic process” the direction of the project.
Phase III has an entirely new goal: decentralization of governance. In short, this means that, instead of Presearch being the primary driver of decisions for the project, it allows the community to take over almost every aspect of governance, the document says.
Technical specifications on how the project works can be found in your whitepaper.
Centralize or decentralize?
Despite the advantages that the use of free and decentralized code brings to the user, it should be noted that blockchain networks may not yet be ready for global adoption.
A clear example of the lack of blockchain scalability was the crash of the Ethereum network in 2017 when the children's game CryptoKitties tested the limits of the network. If a not-so-popular game was enough to slow the network down, when will it be possible to popularize a decentralized application on a global scale?
Ethereum 2.0 and other solutions aim to bring more scalability so that public blockchains can run the Internet decentralized. Will the project work? You can read more about it in the article “Ethereum 2.0: A New Age“.
