@Winter-Soren : Great, thank you for submitting the PR. Reviewing the PR and getting it ready for production level testing. As discussed, reiterating the pointers shared: according to the Gossipsub 1.2 spec, the primary addition at that version is indeed the IDONTWANT control message. The extra features you mentioned—message author validation, IP colocation checks, spam protection enhancements, and extended control messages- are not part of the 1.2 scope. Those were proposed, refined in later iterations (1.3 and 1.4), where the focus broadened to include stronger validation, Sybil resistance measures, anti-spam controls. So your understanding is correct: in 1.2, we only need to ensure we’re compliant with the IDONTWANT mechanism, keeping the implementation lean and true to the spec. The additional enhancements you mentioned are indeed tracked for later Gossipsub versions, and we can plan to incorporate them once we’re ready to move toward 1.4 compatibility. CCing @lla-dane , who is working on peer store integration with Gossipsub. Would recommend him to do integration for Gossipsub 1.2 branch too. |

What was wrong?
Issue #806
py-libp2p was missing support for GossipSub 1.2, which includes important security and performance improvements over GossipSub 1.1. The missing features included:
Without these features, py-libp2p networks were vulnerable to spam attacks and had suboptimal mesh quality compared to other libp2p implementations.
How was it fixed?
Implemented complete GossipSub 1.2 support following the official specification and maintaining compatibility with go-libp2p and js-libp2p implementations.
