decdn-cache

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 is pre-launch — no network is deployed. Wire formats, APIs and on-chain interfaces change without compatibility shims.

The node's cache engine: a store wrapping iroh-blobs with origin pull-through, range admission, partial-blob retention across GC, and prewarm.

Independent of the payment layer by design — the cache works with no payment logic wired in, which keeps it usable for local development and testing. The paid fetch path lives in decdn-client instead.
