Polymer Labs has officially launched Polymer Hub, a real-time interoperability protocol for connecting all Ethereum rollups.
By streaming messages, states and logs over IBC primitives equivalent to Web 2.0’s TCP/IP Polymer Hub verifies and stores the headers of all connected rollups, allowing applications to prove any arbitrary state across rollups at vastly reduced overhead.
Rollup/layer-two ecosystems have historically connected only within their own walled gardens.
With Polymer, however, rollups can now communicate across ecosystems and coordinate as fast as they can produce blocks.
The protocol offers significant improvements in cross-chain communication latency, bandwidth and cost for all on-chain primitives compared to existing solutions.
Polymer aims to make cross-chain interoperability as fast, efficient and affordable as blockspace itself, enabling Ethereum applications to scale to the next million users.
Increase bandwidth reduce latency
Real-time, high-throughput rollups are right around the corner, but existing interoperability protocols point-to-point and hub-and-spoke models were not designed to support dense network traffic across hundreds of rollups.
According to the team, existing solutions are too slow and expensive for the next generation of applications on Ethereum.
As we enter this new era, interoperability solutions must complement their speed and efficiency. Real-time apps require real-time interoperability.
Polymer aims to build the fastest and most efficient interoperability protocol for next-generation rollups like MegaETH.
The hub passes messages in real-time via sequencer pre-confirmations, ensuring cross-chain communication latency can keep up with millisecond block times of these rollups.
Polymer also leverages EigenDA to scale cross-rollup bandwidth to facilitate data-intensive use cases on-chain.
Lei Yang, co-founder and CTO of MegaETH, said,
“Real-timeness the ability to react to inputs with ultra-low latency at massive scale will enable truly ground-breaking [DApps] (decentralized applications).
“Readying the infra stack for this revolution will be a joint effort, in which real-time interoperability from Polymer will be crucial.”
Various technologies like shared sequencers and ecosystem-native interoperability intra-nets have fragmented Ethereum into rollup clusters.
These clusters, however, can leverage Polymer Hub’s…
