Today, the Harmony community is launching the first of its kind subdomain NFT on the Harmony blockchain. These will be live internet domains and each one is unique and non-fungible by design.

The Harmony Foundation owns the crazy.one domain name and we are giving the community the ability to own your personal crazy.one subdomain which is both a NFT and can additionally be linked to your Harmony ONE wallet address via Harmony’s domain name service.

Blockchain domains enable open, transparent and censorship resistant ownership of content on the internet. These domains essentially look like NFTs. We see a future where anyone can truly own space on the internet, by linking their virtual identity to it. Especially when you want to be a part of different communities or tribes on the internet, like ‘The Crazy Ones.

“Here’s to the crazy ones. The misfits. The rebels. The troublemakers. The round pegs in the square holes. The ones who see things differently. They’re not fond of rules. And they have no respect for the status quo. You can quote them, disagree with them, glorify or vilify them. About the only thing you can’t do is ignore them. Because they change things. They push the human race forward. And while some may see them as the crazy ones, we see genius. Because the people who are crazy enough to think they can change the world, are the ones who do.”

If you resonate with The Crazy Ones mentality, join the tribe by claiming your unique crazy.one subdomain.

Anyone can now claim their sub-domain on https://crazy.one by simply completing a transaction on Harmony — within 2 seconds! This is a unique combination of NFTs + blockchain name service + live subdomain service. Your subdomain will be live on the internet and it can serve as your unique identity within the Harmony dApp ecosystem and community.

For example, you could register the following: “satoshi.crazy.one” using your ONE address.

  1. Visit https://crazy.one
  2. Choose your subdomain and check the availability
  3. Pay the rental fee in ONE using metamask.
  4. Add your twitter profile to link it with your live sub domain.

Please note: this is a ONE year RENTAL, not a purchase. This project is also a mechanism by which the Community DAO will be able to generate revenue. As the Community DAO stands up, it will take over the management and operation of Crazy.ONE subdomains and the Harmony Domain Name Service. We are eager to see how this project evolves based on the community aspirations.

Crazy.ONE subdomains is not a “for-profit” concern. All of the tokens used to pay for registration of the subdomain will go directly into the community DAO wallet whose sole purpose is to support the community. Thus, not only will the user experience on the Harmony blockchain drastically improve, this will be a sustainable way for the community to fund Harmony ecosystem projects and initiatives.

For every 100 crazy.one NFTs purchased by the community, we will create a Crazy.ONE NFT using the Harmony logo that has 100 pixels and each pixel is ONE of the 100 owner’s twitter profile picture. We will then drop this NFT into the wallets of those 100 sub-domain owners. This will become one of the official badges of our Harmony tribe.

Here’s the process:

We love interacting with our community and Twitter is an excellent place to ask and answer questions. To engage, not only with the Harmony community, but also with the wider ecosystem, version 1.0 of the crazy.one subdomains project is that your twitter feed (if you link it while registering your Crazy.ONE subdomain) will automatically be shown on your crazy.one page. As the project matures and progresses, we are sure other interesting use cases will be deployed by the community.

We will soon enable the Harmony domain name service, called ONE Names. With this you can link any Harmony address with a human readable name, example: ‘satoish.one’. Harmony ONE wallet, Block explorer and dApps will integrate this and let you send/receive Harmony assets based on your .one names, instead of your hexadecimal address.

We are excited about bringing Crazy.ONE to the Crazy Ones and look forward to what the community will be building next. In the meantime, if you are interested in digging into the technical details, please follow the links below.

Until then, let us never doubt that a small number of determined individuals can change the world. Because that is the only thing that ever has.
