Just when we thought the biggest bottleneck in P2P networking was reaching complex consensus mechanisms or generating efficient proofs, we realized that the fundamental networking protocol stack itself is one of them. Join this session to explore the latest open proposals for optimizing GossipSub in libp2p.
The challenge of broadcasting messages has been a topic of research for over two decades. However, after years of effort from the Web3 community to build robust consensus models and efficient proving mechanisms, we now see that the network protocol stack responsible for decentralization is becoming a critical bottleneck.
For a long time, GossipSub in libp2p has been considered the standard for securely and efficiently delivering messages over P2P networks. However, recent findings suggest that it may not be as optimized as it could be. In this talk, we will explore the latest challenges faced by this core component of decentralized networks and discuss ongoing research efforts and proposals aimed at improving its efficiency.
