Blockchain FileSystem (BCFS)

This crate provides a blockchain filesystem for use in a WASI Wasm runtime. The implementation is based on the Blockchain WASI proposal (link to high-level blog post).

You can find examples of using BCFS in src/lib/tests.rs.

BCFS can be compiled to Wasm so that it can be used in integration tests. Just build using cargo build --target wasm32-unknown-unknown. BCFS exposes FFI bindings so that it can be called from, say, JavaScript in the browser. To build the bindings, you'll want to pass --features ffi.
