## deCDN

- `storage/decdn` | fails-quota | evidence reported | binding write-gated | category Decentralized CDN — paid per MB in USDC, iroh transport
- needs card no, phone no, ID no, institution no | verified 2026-10-21 (inherited) | stale on 2026-11-05
- url https://decdn.org/
- free tier: No free capacity. No storage tier at all: 'Not a blockchain or storage network — durability relies on cheap, reliable object storage (S3-class) owned by origin operators.' Target delivery price $0.01/GB (node default rate `payment.rate_per_mb = 10` = $0.00001/MB). | unit: GB | metered on: stored-bytes | read on: 2026-10-21 | source: [1]
- per-object cap: not stated | source: [1] | note: not stated
- retention: not stated | source: [1] | note: not stated
- 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. | metered: yes
- identity: email | detail: email
- interface: cli
- limits:
  - per-ip-shaping: 1 Gbps [1]
  - write-gated (binding): approved, the rest of the network accepts your nodes as origins'), so publishing is writ [1]
  - write-gated (binding): approval-gated [1]
- limits note: 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.
- interface detail: 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.
- notes: the same as the free tier
- extras:
  - dead_end.failure_class: paid
  - dead_end.why: No free capacity. No storage tier at all: 'Not a blockchain or storage network — durability relies on cheap, reliable object storage (S3-class) owned by origin operators.' Target delivery price $0.01/GB (node default rate `payment.rate_per_mb = 10` = $0.00001/MB).
  - dead_end.first_recorded: 2026-10-21
- evidence:
  - [1] 2026-10-21: content-addressed, paid per MB, origin-hidden, bonded/slashable, 'Not a blockchain or storage network'
  - [2] 2026-10-21: '$0.01/GB' target, split fetch over >64 MiB with ≥2 holders across up to 4 operators, origin 'Once you get approved'
  - [3] 2026-10-13: 2026-10-13 public testnet, sponsor-capped allowance, 'nothing to pay and no account to make', pilots by email
  - [4] 2026-10-21: bond curve 12.6 x Mbps^1.2, testnet minBond 50,000 TOKEN, 14-day unbond, operator share 60% testnet / 90% at mainnet launch
  - [5] 2026-10-21: UDP 4433 public, 5 TB/month egress recommended, cache 250 GB-1 TB
  - [6] 2026-10-21: 'no single vendor can reprice you'; the pitch is verified delivery, not free bytes
