decdn-common

Part of deCDN — a decentralized CDN where nodes cache and serve BLAKE3-addressed blobs over iroh QUIC, and clients pay per megabyte in USDC with off-chain vouchers backed by a shared on-chain payment pool.

Status: early implementation. deCDN runs a public testnet on Arbitrum Sepolia and is pre-mainnet. Wire formats, APIs and on-chain interfaces change without compatibility shims until mainnet.

Types shared by the two deCDN binaries (decdn-node and decdn): the config schema and its resolver, the shared clap argument definitions both binaries build their command lines from, node identity loading, and the local admin JSON-RPC trait plus its request/response DTOs.

Split out so the daemon and the CLI agree on config and admin wire shapes by construction rather than by convention — see the dockerd-style two-binary rationale in the binaries appendix.
