Polymer Launches Real-Time Interoperability For Ethereum Rollups | HackerNoon
Briefly

Polymer Hub enables real-time interoperability between Ethereum rollups, allowing them to communicate efficiently and reduce overhead to scale Ethereum applications significantly.
By streaming messages and states over IBC primitives, Polymer Hub can verify and store headers of all connected rollups, facilitating rapid cross-chain communication without costly delays.
Existing interoperability protocols have limitations in speed and cost, but Polymer Hub is designed to handle the high throughput needed for the next generation of Ethereum applications.
The polymer framework enhances cross-chain communication with ultra-low latency, aiming to support dense network traffic and improve user experience for Ethereum applications.
