Appendix A - External Network Libraries

gorilla

Algorand uses a fork of gorilla websocket (v1.4.2), to implement the Relay Network.

Relevant changes:

• Header size and read limits,

  • connection.ReadMessage() is marked as unsafe to avoid explosively compressed messages.

• Server is TLSServer,

• Message compression,

• Mutexes for multithreading,

• Connection closing without flushing, and a thread flusher,

• Tests and benchmark over additions.

Further details refer to the fork.

libp2p

Algorand uses go-libp2p library (building from the latest release), to implement the Peer-to-Peer network.

See libp2p specifications for detailed documentation on this external package.
