## Issue Addressed Upgrade libp2p to v0.52 ## Proposed Changes - **Workflows**: remove installation of `protoc` - **Book**: remove installation of `protoc` - **`Dockerfile`s and `cross`**: remove custom base `Dockerfile` for cross since it's no longer needed. Remove `protoc` from remaining `Dockerfiles`s - **Upgrade `discv5` to `v0.3.1`:** we have some cool stuff in there: no longer needs `protoc` and faster ip updates on cold start - **Upgrade `prometheus` to `0.21.0`**, now it no longer needs encoding checks - **things that look like refactors:** bunch of api types were renamed and need to be accessed in a different (clearer) way - **Lighthouse network** - connection limits is now a behaviour - banned peers no longer exist on the swarm level, but at the behaviour level - `connection_event_buffer_size` now is handled per connection with a buffer size of 4 - `mplex` is deprecated and was removed - rpc handler now logs the peer to which it belongs ## Additional Info Tried to keep as much behaviour unchanged as possible. However, there is a great deal of improvements we can do _after_ this upgrade: - Smart connection limits: Connection limits have been checked only based on numbers, we can now use information about the incoming peer to decide if we want it - More powerful peer management: Dial attempts from other behaviours can be rejected early - Incoming connections can be rejected early - Banning can be returned exclusively to the peer management: We should not get connections to banned peers anymore making use of this - TCP Nat updates: We might be able to take advantage of confirmed external addresses to check out tcp ports/ips Co-authored-by: Age Manning <Age@AgeManning.com> Co-authored-by: Akihito Nakano <sora.akatsuki@gmail.com>
