decdn-node

Part of deCDN — a decentralized CDN where nodes cache and serve BLAKE3-addressed blobs over iroh QUIC, and clients pay per megabyte in USDC over off-chain payment channels.

Status: early implementation. deCDN runs a public testnet on Arbitrum Sepolia and is pre-mainnet. Wire formats, APIs and on-chain interfaces change without compatibility shims until mainnet.

The decdn-node daemon: runtime bring-up, protocol handlers, the local admin JSON-RPC server, the dispatch limiter, and Prometheus metrics.

cargo install decdn-node
decdn-node run

Container images are published as ghcr.io/decdn/decdn-node and decdn/decdn-node. The image also carries the decdn CLI, so docker exec <container> decdn node status works. Configure the daemon with decdn config init from the decdn-cli crate.
