Per-MB payment is mandatory for clients on mainnet — there is no free reader tier. Namespaces gate the origin role ('Once you get approved, the rest of the network accepts your nodes as origins'), so publishing is write-gated by a human. Node bond on testnet is 50,000 TOKEN for anything up to ~1 Gbps; unbonding takes 14 days. 0.4% verification overhead plus node-to-node pull costs. |

| Identity | email email |
|---|
| Egress | $0.01/GB target, set per node and signed into every quote; client sets a ceiling. Testnet is sponsor-funded with a capped allowance — 'there is nothing to pay and no account to make' — but that is testnet money on Arbitrum Sepolia. |

| Interface | cli Client SDK (Rust; macOS/Linux/Windows, phone/browser in testing) + decdn CLI: decdn get 'decdn:<blake3hash>/?ns=1'. One human-verification step in a browser on first install. |
|---|
| Tooling | Install via curl -fsSL https://up.decdn.org/decdn.sh | sh -s -- get '<uri>' (both scripts returned HTTP 200); PowerShell variant; node operator side is decdn setup / decdn node bond. |
|---|
| Composes with | Origin node in front of your own S3/R2/B2/NFS/local disk stays hidden; bonded nodes cache and re-serve over iroh QUIC with bao-encoded verified streaming. Multi-source fetch splits blobs >64 MiB across up to 4 nodes, one per operator. Publisher's own origin pulls are free — cache misses cost the serving node, not the publisher. |
|---|
| Reliability | Public testnet only (Arbitrum Sepolia, launched 2026-10-13); governance hash blacklist forces nodes to stop serving a listed hash within 24 h, and the origin role is approval-gated. |
