Crate host_chain_core 

host-chain-core — WASM-compatible portable networking, parsing, and chain types.

Compiles to both native (x86_64, aarch64) and wasm32-unknown-unknown. Uses reqwest as the sole HTTP client: rustls-tls on native, browser fetch() via web-sys on WASM — same Rust code, no JS glue. Uses ruzstd for zstd decompression (pure Rust, no C FFI).

Modules

• car — CARv1 / UnixFS parser (ruzstd for decompression)
• chain — shared chain data types (ChainId, ChainState, etc.)
• dotns — async DOTNS resolution pipeline (reqwest for HTTP)
• identity — async username resolution via Substrate Identity pallet
• registry — genesis-hash-to-ChainId lookup table
• state_machine — generic chain state machine (shared WASM/native)
• store — chain database persistence abstraction

Modules

car

CARv1 / UnixFS parser for .prod bundles.

chain

Shared chain data types — WASM-compatible, no platform-specific deps.

dotns

Async DOTNS (DOT Name Service) on-chain resolution.

identity

Async username and consumer identity resolution against the Identity and Resources pallets on People chains.

registration

Async HTTP-based helpers for username registration on People chains.

registry

Chain registry — maps genesis hashes to chain identifiers.

state_machine

Generic chain state machine — shared between WASM and native.

store

Chain database persistence abstraction.

subscription

Generic statement-store subscription — trait definitions and StatementStoreSubscription reconnect/dedup/dispatch infrastructure.
