deCDN is a decentralized content delivery network. Instead of a single provider operating all edge servers, staked independent nodes cache content and deliver it to clients over peer-to-peer QUIC connections. Clients pay nodes directly, per megabyte, over off-chain payment channels.

Core properties

  • Content-addressed. Every blob is identified by its BLAKE3 hash. Clients verify the bytes they receive — they do not trust any node to return the right content.
  • Paid per megabyte. Every byte delivered is paid, including node-to-node cache-miss pulls. Payments run on off-chain channels denominated in USDC (fixed at deployment), with on-chain settlement only at channel open and close.
  • Origin-hidden. Origin backends (S3, R2, B2, NFS, local disk) are opaque per-node configuration. No external origin URL is ever exposed to the network.
  • Bonded and slashable. Nodes post a TOKEN capacity bond (scaled to declared bandwidth) to join the peer mesh. Slashable offenses have on-chain evidence paths that anyone can challenge.
  • No single operator. Gossip for discovery. A DHT for content location. Optimistic challenge-response for disputes. Operator governance weighted by delivered bytes, with a timelock for parameter updates.

What it isn’t

  • Not a blockchain or storage network — durability relies on cheap, reliable object storage (S3-class) owned by origin operators.
  • Not a transcoding or search service — delivery only.
