# Transaction processing flow Formless uses the improved libp2p-gossip-pubsu to realize the message broadcasting/subscription function, through the seed node setting for node automatic discovery and automatic connection functions, each online node can be used as the seed node of other nodes to provide network discovery services by default. The automatic networking mechanism of the Formless public chain ensures that messages can eventually reach all nodes online. In the multi-chain scenario, each chain on the node has an independent GossipPubSub service, and through precise control of each Gossip routing table, the broadcast data isolation between multiple chains can be realized, ensuring that the broadcast data only transmits across the nodes of the chain. In theory, tens of thousands of nodes can form an online network of consensus at the same time. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
