decdn-bao-range 0.0.2

Leaf crate: iroh-blobs-free bao verified-range helpers (chunk-group alignment, encoded-size, range encode/verify) shared by decdn-cache (serve/import) and decdn-client (receive). Depends only on bao-tree so the CLI's iroh-blobs-free invariant (#578) holds.

decdn-bao-range

Part of deCDN — a decentralized CDN where nodes cache and serve BLAKE3-addressed blobs over iroh QUIC, and clients pay per megabyte in USDC over off-chain payment channels.

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.

bao-tree-based verified-range helpers: chunk-group alignment, encoded-size arithmetic, and range encode/verify against an untrusted {hash}.obao4 pre-order outboard.

Deliberately free of iroh-blobs. That is what lets the publisher CLI request and verify byte ranges without linking a blob store — see ADR 038 for the range-transfer design.
