deCDN

deCDN is a peer-to-peer content delivery network — an open, programmable delivery layer for any large file. Today's distribution depends on a handful of centralized providers: legacy CDNs (CloudFront, Akamai) charge $0.04–$0.20 per gigabyte list, while $0-egress object storage (Cloudflare R2, Backblaze B2) gives the price away to lock you into a single vendor's roadmap, terms, and outage surface. Either way there is no operator transparency and no way for anyone outside the incumbents to participate in the market.

deCDN replaces that bottleneck with a peer-to-peer mesh. Node operators bond TOKEN, cache BLAKE3-addressed content, and earn USDC for every megabyte they serve. Clients probe available nodes for latency and price over QUIC (0-RTT), then stream directly from the winning peer — every byte cryptographically verified against its content hash, every payment cleared through off-chain USDC channels with on-chain dispute resolution. The target rate is around $0.01/GB, up to 90% cheaper than legacy CDN list pricing, and it falls as the network grows. deCDN does not claim to undercut $0-egress object storage on the egress line; it removes the single-vendor dependency, pricing delivery on an open market no provider can reprice or revoke.

The architecture is verifiable by construction: corrupted or phantom-announced content is instantly detectable and slashable. End-to-end encryption keeps content opaque to operators while preserving global cacheability. The network self-heals — cache misses trigger paid peer pulls that warm the grid around demand.

Built in Rust on the iroh QUIC stack, with USDC for payments and a native TOKEN for bonding (slashable operator bonds) and served-bytes governance. The initial deployment targets tens of nodes on an Arbitrum Sepolia testnet, with production launch planned on Arbitrum One.
