# Communities

Clusters is the best way to issue usernames to your community. A community like *treasure/* can issue thousands or even hundreds of thousands or free and paid usernames like *treasure/karel*, *treasure/yuri*, *treasure/foobar*. There are three key advantages:

* **Brand Awareness -** cluster names are visible across leading block explorers like Etherscan, wallets like Metamask, and bridges like LayerZero
* **Clean Aesthetics** - it looks way cleaner to have *treasure/karel* than karel.treasure.eth.
* **Make Money -** communities can combine a free or a paid approach and earn from both community name signups and upgrades to personal clusters
* **Fastest Launch** - no need to develop or deploy your own smart contracts, we take care of it all with a white-label solution

**How do I set it up?**

We provide a flexible settings panel where you can choose community images, names, payment currency, pricing, and more. We provide a simple default interface that users can register on our site but expect to work with partners to set up a seamless experience on their community website.

**What's the technical architecture?**

Clusters takes an appchain approach for both decentralization and scalability. Cluster names are decentralized digital assets, and full cluster configuration is replicated onto a data availability layer (currently Arweave) so that full protocol state can be permissionlessly indexed and replicated by anyone. However most integrators and community partners interact solely with our REST/JavaScript APIs for simplicity. Community name registration can be done either offchain via API (for free names) or onchain via smart contract call (for paid names).
