ARCHITECTURAL ADVANTAGES
Why Build a Sovereign Streaming Chain
Sovereign streaming chains built with the Cosmos SDK's Streaming Module unlock new paradigms in data accessibility, performance, and developer control. Move beyond the limitations of standard full nodes.
02
Enhanced Performance & Scalability
Offload intensive data processing from consensus-critical nodes. Our streaming chain architecture isolates data services, preventing them from impacting block production speed or network stability.
