Problem
Delivering large files such as OS images, datasets, game patches, or AI models relies on traditional CDNs that require fixed provisioning, long‑term contracts, and centralized infrastructure, leading to high per‑gigabyte costs and limited scalability for bursty demand. Users also face latency and reliability issues when the origin or regional edge nodes fail, and they must trust the provider without cryptographic verification of each byte.
Solution
deCDN offers a decentralized, peer‑to‑peer delivery layer that routes large files through a mesh of nodes located near the client. In a single probe handshake, the client discovers nearby peers, evaluates their price, latency, and reputation, and selects the best‑priced, fastest nodes, optionally opening parallel streams to multiple peers for high throughput. Each data chunk is addressed and verified with a BLAKE3 hash as it arrives, providing byte‑level integrity without trusting any single node. Payments are settled per megabyte in USDC automatically as the data streams, eliminating subscription fees and monthly minimums. The open‑source protocol runs on QUIC/iroh transports, uses Rust for performance, and is chain‑agnostic for settlement, enabling a cost‑effective, low‑latency, and fault‑tolerant delivery experience.
Target Audience
Primary customers are content publishers, software distributors, and data providers who need to deliver large binary assets at low cost and high speed, as well as developers of applications that require decentralized, integrity‑verified file distribution.
Features
- Probe phase: single‑handshake discovery of cached peers with price, latency, and reputation metadata, round‑trip under 100 ms
- Swarm mode: parallel streams to multiple peers for multi‑gigabit aggregate throughput, scaling beyond a single origin’s bandwidth
- BLAKE3 chunk‑by‑chunk verification with on‑the‑fly fraud proofs and token slashing for misbehaving nodes
- Per‑megabyte settlement in USDC via a chain‑agnostic payment channel, no subscription or minimum billing
- Open‑source stack built in Rust, leveraging QUIC and iroh transport layers for efficient, low‑latency data transfer
- Token‑secured network where operators stake TOKEN to guarantee service quality, while payments remain in stable USDC
- Governance‑driven content gating and takedown via on‑chain hash flagging and automated slashing of non‑compliant nodes
