Field notes
The design represents each siding as a JSON document plus a key, with deterministic genesis and blocks that carry a signature satisfying the chain’s challenge. Its peg model mints exactly the amount locked on the parent and describes a timelocked refund path if the sidechain fails. The page lists three BLAKE2b testnet4 chains, each with one signer, and separates validation into Signed, Proven, and Federated levels.
