Decentralized Search Engine

PREsearch Mainnet Is Going Live

By Ari King | IoT: The People's Network | 23 May 2022

What is Mainnet and why is it so monumental for Presearch?

Ever since we launched the Presearch node Testnet back in October of 2020, we’ve been working hard toward launching Mainnet and are now in the final days before it goes live.

But what is Mainnet and why is it so monumental for Presearch and its future as the leading search engine of the web3 era?

What is Mainnet?

First, for those not familiar with the term, a node is a server or computer running a piece of software that enables it to connect to a larger distributed computer network and play a role in operating and powering that network. Mainnet is the way the crypto space refers to the public launch of a network that has been in testing phase.

The Presearch Mainnet launch is more than just the public launch of Presearch’s decentralized search network powered by more than 60,000 user nodes.

Mainnet is also the culmination of a number of developments to improve the Presearch user experience and ensure the project is ready to take to the masses, creating massive value for the Presearch Keyword Staking platform and in-turn the PRE token.

These developments include:

  • The switch to
  • An improved homepage experience
  • Improved anti-abuse system
  • Enhanced search results experience
  • Web3 withdrawals (going live shortly after Mainnet launches)

That said, far and away, the most significant change that Mainnet brings from a technical standpoint is the deployment of the Presearch decentralized search node network to begin serving public user search requests.

To help you better understand what this means for the project, and why decentralized search infrastructure is such a big breakthrough, we’ve prepared this post as well as some others we’ll be releasing as we approach Mainnet launch.

Traditional search engine infrastructure

Before we talk about decentralized search nodes, and how they’re used within the Presearch ecosystem, let us first review the infrastructure powering traditional search engines like Google, Bing and even upstarts like Brave.

A Google data center in St. Ghislain, Belgium. For more information on Google’s data operations, including this source photo, click here:

Google alone has 23 massive data facilities that power its computing and infrastructure requirements. These data centers are impressive feats of engineering costing billions of dollars, staffed by an army of technical and operational employees and powered by an incredibly amount of electricity that also costs billions of dollars each year.

Owning and operating these systems requires a highly corporate structure that requires not just real estate and employees, but all of the supporting legal, accounting and administrative resources that make it possible to have the physical presence that supports the scale of a big search engine.

This model has worked — and continues to work — well for the existing legacy web1 and web2 search engines. Data centers like these provide speed, scalability and reliability with redundant power sources, backbone internet connections and cooling facilities to keep tightly-packed servers running 24/7.


While this model of cloud computing — offloading the computing resources from the user’s device to a remote server — has been extremely effective versus the pre-cloud days of running software locally, there’s a new model of distributing computing infrastructure requirements out in a more decentralized manner that stands to make the existing cloud paradigm seem more like the mainframe model of days gone by.

The Web3 infrastructure model

The Web3 infrastructure model, which is used by Bitcoin, Ethereum and decentralized projects like Presearch, enables independent computing resource providers around the world to contribute the power of their servers and computers to decentralized networks, replacing the need for a central entity to operate physical servers or traditional cloud accounts that may be vulnerable to censorship and cancellation.


In this model, those who contribute resources are able to be rewarded in the native cryptocurrency token of the project they support, enabling these resource providers to not just be paid for their services, but to capture a fragment of the value of the entire network they are enabling to exist, resulting in a distributed value model that puts the people who power the network in a position to benefit from its growth in value over time.

In addition to distributing value, this model has many additional benefits, including resilience, scalability, security and community integration, whereby those providing the infrastructure become key growth engines for uptake due to having a vested interest and a participatory role in the project.

You may have heard the adage that the rocket that blasted the Apollo mission to the moon in 1969 had less computing power than a modern watch, and it’s not an exaggeration. A smartphone of today is millions of times more powerful than this legacy technology, and the web3 infrastructure model is poised to disrupt the legacy cloud model in time as well.

With such fast internet connections, affordable bandwidth, high-capacity processors, plentiful memory and reliable hardware now available across the world, from billions of people and millions of companies, the ability to harness these resources for common infrastructure projects is now feasible, and in fact much more powerful than the highest-quality infrastructure available when Google first began to build its data centers.

While peer-to-peer and decentralized infrastructure was once second-rate, offering noticeably slower response times and low reliability, today’s internet-connected devices are able to compete with centralized hardware.

There are limits to a human’s ability to perceive differences in load times of information, and we are quickly approaching a point at which any perceptible speed difference can be easily overcome with smart network optimization and clever user interface technology.

The time for web3 infrastructure to rise and usher in the next generation of internet services, that are literally built by and for users is here, and Presearch is grateful to our community for providing the opportunity to apply the web3 model to the most important utility on the web: search.

Decentralized search nodes

In their current form, Presearch nodes receive anonymized queries from what we call ‘node gateways’, which are located around the world in different regions where Presearch has users. Some areas have more node gateways than others, based on usage rates in that area.

Once a node has received a query, they use that term or set of terms to retrieve search results from other external platforms — legacy search engines, databases and APIs. After they’ve retrieved results, they return the list of related links back to the node gateway which builds the results page and returns it to the searcher.

Nodes can operate on your home computer, on a dedicated device like a Preberry, or on a virtual server. Each has benefits and drawbacks, and there’s an entire community chat room dedicated to helping people get started and optimize their nodes.

Node operators are rewarded with small amounts of Presearch’s PRE token for every query that they successfully process, and there is a dashboard in the Presearch platform ( that displays how many queries have been processed, how much a node operator has earned, and to make changes to their node settings.

Please watch the video below for an illustration of how it all works.


Now, this current role — where the nodes are getting information from other sources — is just the first one being launched. Eventually there will be other roles, which we will discuss in future posts.

The top 5 reasons Mainnet matters so much

These are some of the biggest reasons that Mainnet matters, and why Presearch is becoming better positioned to be the top search engine of the web3 era.

1. The foundational infrastructure layer upon which we build all the things

The first reason this is a huge deal because nodes are the fundamental layer of infrastructure the project requires to handle all of its ongoing computing requirements.

We now have the ability for node operators to contribute computing resources, be rewarded for their contributions, and have the network automatically distribute those resources to the locations and tasks that require processing.

Although we’re starting with what we call the ‘federating’ role, we can now build out the other roles required to build and power the Presearch decentralized search index — crawling, indexing, file storage, etc. — and deploy an update to the network and have thousands of users begin handling those tasks.

2. Geographic distribution of node gateways and nodes

The second reason Mainnet is a breakthrough is that due to geographic distribution, the speed of running searches for global users will improve due to closer proximity between searchers and the computing resources they will access.

Before Mainnet, all traffic is being routed through the US, and the network is being powered by significantly fewer servers, making searches less able to be optimized for a user’s geographic location. US users should see stable search speed moving forward, though there may be improvements as well as we eventually add more node gateways around the continent.

3. Increased resilience of the network

The third reason Mainnet is a big deal is that as the footprint of the network gets wider, it becomes more resilient and is less likely to experience blocks, rate-limiting, regional outages or other issues that could lead to the platform not working.

With a decentralized network, there are more factors to optimize to ensure top performance, but there is a significant increase in the network’s ability to withstand catastrophic blockages that render it broken. In the case of the current federating role, this is very important.

4. A working proof of concept that decentralized search works

The fourth reason Mainnet is an awesome development for the Presearch community is that the project is taking a major step toward its ultimate vision of becoming completely decentralized and being able to provide the world with an alternative search engine that is built by and for the community.

Launching one of the world’s largest decentralized networks, handling millions of daily search requests is a significant feat, and proves that the project is heading in the right direction according to the plans published in the vision paper.

Presearch is quickly becoming a credible contender in the search space, and with this development, we are in a great position to execute on bringing millions more users into the platform and increasing the value of the advertising platform, thereby growing demand for PRE.

5. More traffic and rewards for node operators

The fifth reason we are so excited about Mainnet is that this is a great milestone for the community of thousands of node operators, running more than 60,000 nodes, who will now see significant increases in the volume of search requests they receive, as well as continued growth in search rewards as the economic value of serving real traffic is greater, and the marketing opportunity is now upon us.

The Road to Mainnet and beyond

Leading up to May 26th, the project will be launching geographically-distributed gateways around the globe that local nodes can connect to.

The team will also roll out the rest of the developments included in the launch, such as web3 withdrawals, the new homepage and transitioning of the platform from to

While there will be many more functions to decentralize over time, this is a massive step forward for the project and its ambitions to continue growing rapidly in order to ultimately become a top 100 crypto project with one of the largest search user bases in the world.

With many of the pain points of the project in the rear view mirror, and an incredibly solid, community-driven foundation to build upon, Presearch is poised for major growth in usage as well as the ability to make rapid progress against the project’s development roadmap.

We’ll release our updated product development roadmap in the coming weeks post Mainnet.

Exciting times for all Presearchers! Thank you all for your support in realizing this incredible milestone!
