 these projects. We diligently went through and performed initial outreach to the authors,
 and here is what we found to be some of the top projects on this list.
 
-* https://github.com/ipfs-rust/rust-ipfs
-    * This is likely the furthest along in terms of a Rust IPFS implementation. It contains implementations of the block, dag, ipns and a few other APIs. However, there are no CLI or HTTP bindings as of this writing
-* https://github.com/libp2p/rust-libp2p
-    * Parity’s implementation of libp2p in Rust, which includes their own in-tree versions of rust-multihash and rust-multiaddr. The next two items on the list would capture the requirements not covered, i.e. cid and multicodec
 * https://github.com/multiformats/rust-cid
 * https://github.com/mudlee/rust-multicodec
-* https://github.com/ipfs-rust/rust-ipld
-    * Most advanced IPLD library with support for protobuf, cbor, and json
 * https://docs.rs/ipfs-api/0.6.0-rc/ipfs_api/
     * HTTP Bindings for Rust to call the standard IPFS HTTP API
-* https://github.com/vmx/rust-ipld/
-    * Protocol Labs internal work on rust-ipld.
