Presearch 价格 

PRE

Presearch offers several products with real-world utility. Its search tool allows users to search the internet in the same way they are used to with search engines like Google or DuckDuckGo. Users can choose between searching on the default Presearch engine or switching to results from more than 150 different providers. Presearch also offers search rewards to its users, the more you stake, the more you earn per search.

For advertisers, Presearch offers a wide array of attractive products including a Search API and homepage/search results page takeovers. Additionally, Presearch developed a propietary Keyword Staking mechanism. Token holders can stake their PRE against specific words or search terms to display ads to users. If a user searches for a term, the Presearch algorithm shows the ad with the most PRE staked belonging to this term. If there are no matches for a long-tail keyword, it breaks down the term into individual words and picks the ad with the most PRE staked on a single word from the search query.

Furthermore, Presearch also provides a browser extension on Firefox, Edge and Chrome that enables users to search from their address bar in their web browser and use Presearch as the default search engine.

The total circulating supply of PRE is 500 million and Total minted supply is 750 Million PRE. The Max supply is 1 Billion PRE.

PRE has several use cases within the Presearch ecosystem: users can stake and receive PRE as a reward for searches, use it to make purchases for advertising and the Search API, and stake it on our decentralized node infrastructure to earn PRE for every search your node processes. Node operators stake PRE to secure the network, while partners can pay and stake PRE to be added as a search provider. Currently, 5% of gross revenue on the platform is used for buybacks on the open market with an ultimate goal of 50%.

PRE is an ERC-20 token on Ethereum. ERC-20 is a token standard most new tokens follow when publishing on the Ethereum blockchain. Ethereum is one of the most popular blockchains and the go-to solution for many decentralized applications and exchanges to launch on.

The platform is secured by nodes, which connect to a Node Gateway that receives requests from the server and removes personally identifiable information from the search requests. A node registry manages the identity of all nodes, the node stats and payouts. Nodes are compensated in PRE for different types of services:

1) Registering (all nodes). Registering with a Node Gateway, which can then route queries to the node if it passes health and security validation.

2) Validating (all nodes). Coordinating with a Node Validator to ensure that each node is only running trusted Presearch software (to avoid security issues from potential bad actors).

3) Coordinating. Processing and distributing queries sent by Node Gateways. This may require routing to multiple serving nodes and aggregating the results.

4) Federating. Proxying other data sources and returning their data as part of search results.

5) Serving. Hosting portions of the search index used to process queries.

6) Crawling. Crawling websites to build out search indices.

7) Indexing. Writing federated or crawled data to search indexes to be served by serving nodes.
