The original GossipSub design emphasizes robustness, with less focus on message sizes. However, emerging use cases—such as Ethereum's EIP-4844 and data availability sampling (DAS) require rapid propagation of high data volumes, often in the form of large messages. Many ongoing research efforts attempt to find solutions for efficiently forwarding large messages through the GossipSub network. This post provides a concise overview and performance evaluation of some research initiatives aimed at improving GossipSub to meet the performance needs of modern P2P networks.

Zerokit is a toolkit providing powerful zero-knowledge utilities, including a means to answer the question "How do you prevent spam when every message is anonymous?". Its use of the Merkle hash tree, combined Poseidon hasher are keys to the answer we seek here, and with other questions that ask the improbable. These technologies, however, can take a heavy toll on resources if not used correctly. What follows is a window into the efforts made to squeeze out optimizations, and culling of redundant resource use. A story of cripplingly slow performance meets engineering talent, we arrive at a place where Zerokit comes through, fast and efficient, ready to face the world.
