Introducing One OS

Introducing One OS - A layer on top of your device to access Harmony Blockchain

Whether you are a trader specialized in the crypto world, a collector of NFTs , or if you manage a node , you are a blockchain validator or you develop software , you will agree that the usability of the applications you use in your day to day is a critical point for the management and security of your digital assets.

And it is that Blockchain technology comes with a strength and weakness at the same time: The custody of your keys and the immutability of the registry. This basically means that whether you lose your keys, make a wrong transaction or sign a multisig without understanding its content, it can lead to terrible consequences and great losses that cannot be reversed. For this reason, and after developing +30 projects and official wallets at Peersyst, we care a lot about clarity, usability and security for all software that uses blockchain.

When we began to contribute to the Harmony One ecosystem, we started to see all the options offered by the technology as well as the applications that were available, both in wallets and in dApps. The first thing that surprised us is that in a blockchain that handles about 4M daily transactions at the time of this article, with more than 800k accounts and more than $2,000,000,000 of fully diluted marketcap , there was no solid, usable and scalable platform for all its holders, which would allow them not only to use their assets easily but also to have a clear vision and access to all their dApps.

With this problem not only present in Harmony, but in practically all blockchains, the idea of ​​One OS was born. A layer on top of your device , be it desktop or mobile, that brings the usability and ease of traditional and modern software that most of the population is familiar with.

Our proposed solution: Cross-chain plugin-based platform

The idea is to enhance both the accessibility and usability of both solutions, decentralizing development and support through a plug-in system that allows everyone to contribute and collaborate in the same direction. For this, the following is established:

  • Delegate the responsibility of cross-chain / keys management to «Metamask» and individually manage each blockchain.
  • Connect the network to a platform , where all the applications and functionalities of the blockchain are collected.
  • The platform can be powered by a plugin system , open to all communities.
  • Blockchains can develop «core» or official software, and the community can support their dApps

Product Research: Starting with the best of today

To meet this challenge, we did extensive research on the best applications, frameworks, dApps and technologies that we could find today, both in the blockchain world and outside of it, to try to create usable software for everyone. This was the result:

One OS Brand: One software to rule them all

Finally, we needed a powerful, easy and clear brand for our product. We think of Harmony OS , due to its resemblance to an operating system over devices, but this name was already reserved by Huawei. So, we decided on One Os, clean, simple and with global usability.

Final Product: Putting all the pieces together

We applied the correct branding and UI to the previous wireframes to guarantee great usability , both for our software and for the new dApps that are included in the OS. We also decided to incorporate themes , so that the community can create, download and install their favorite display colors.

One OS Wallet Dark

Easy to customize your wallet and your sections with «Drag and drop», since this software is of vital importance and used by and for everyone.

The vitally important cross-platform shows us what it would look like on mobile :

One OS Mobile Version

A marketplace where you can find and search for dApps , very similar to, but allowing you to install new dApps directly to One OS.

One OS uninstall app

A spotlight that includes native features and efficient searches between apps and features

Finally, the inclusion of dApps . One OS is the reference platform if it includes support for multiple software. With our team, Peersyst can guarantee the development and access of the main fundamental applications of the ecosystem, such as the Wallet , t he Marketplace , integration of the main Bridges , basic tools such as Staking or Multisig present in Harmony are also on our roadmap. Finally, tools to facilitate the development and deployment of Harmony to everyone, allowing access to the main standards, modification and deployment in a few clicks, as well as more advanced tools for testing and execution of contracts will be included.

Looks very nice! I’ll be testing this a lot :rocket:
Is it available yet?


Also, is there any affiliation with this OneOS or is it just a coincidence?

Thank you for your feedback! We get highly inspired in Harmony Universe for the marketplace, your support would be fantastic there.

We are working to create a DAO for One OS to fund the project and the community plugins. We have the team and expertise to do so :+1:t2:, but it will only work if its a community collaborative platform.

We will explain the milestones and roadmap on the DAO proposal already with the timings!

We are also open to accept people who want to contribute in the DAO!

Any further word on how you guys are planning to move forward? Is this a DAO seeking funding? Launch grant?


Yes, the idea is to create a DAO. The project is pretty big, and as much contributors and people imvolved we can get better.

So the idea is to create a DAO and fund it to allow the development of the One OS and also fund contributors who build their plug-ins and dApps!

Everyone that also have an application running on Harmony will be very welcome to add the plugin there :+1:t2: As much dapps there the better and more usable will be available for everyone! :blue_heart:

Here is a series of videos we are doing presenting the product
