Connecting Domains to Decentralized Hosting

A key use case for Web3 domains is decentralized website hosting. Instead of relying on centralized servers, your website files are:

  • Uploaded to the InterPlanetary File System (IPFS hosting), which distributes content across a global peer-to-peer network.
  • Assigned a unique Content Identifier (CID), which is then linked to your Web3 domain through the provider’s dashboard.

This setup ensures permanent, censorship-resistant hosting where you, not a central provider, control site availability and updates.

Using IPFS for Website Hosting

IPFS hosting brings significant advantages:

  • Provides resilience against downtime and DDOS attacks by eliminating a single point of failure.
  • Ensures content immutability—past versions can be retained or reverted as needed.
  • Integrates seamlessly with Web3 domains for easy updates: update your content, upload to IPFS, and refresh the content hash.

Site builders like Pazly and templates from Unstoppable Domains simplify the process for non-technical users.
