Polymer Labs officially announces the launch of Polymer Hub, a protocol that provides real-time interoperability for all Ethereum rollups. By streaming messages, states, and logs, and based on IBC primitives (similar to Web2's TCP/IP), Polymer Hub can verify and store the block headers of all connected rollups, enabling applications to validate arbitrary states across different rollups with lower overhead.
In the past, the Rollup/L2 ecosystem could typically only interconnect within their own isolated environments; however, Polymer breaks this limitation, allowing Rollups to communicate and coordinate in real-time across ecosystems, with speeds nearly synchronized with block generation. Compared to existing solutions, this protocol offers significant improvements in cross-chain communication latency, bandwidth, and cost, especially in scenarios involving all chain primitives.
Polymer aims to make cross-chain interoperability as fast, efficient, and economical as the blockchain space itself, helping Ethereum applications scale to millions of users.
Enhance Bandwidth, Reduce Latency
Real-time, high-throughput Rollups are on the horizon, but existing interoperability protocols (such as peer-to-peer and star network models) are insufficient to support the heavy network traffic among hundreds of rollups. The Polymer team points out that current solutions are too slow and expensive for next-generation Ethereum applications. As technology advances, interoperability protocols must meet the speed and efficiency demands of real-time applications. Future application scenarios require real-time interoperability.
Polymer aims to build the fastest and most efficient interoperability protocol for the next generation of Rollups (such as MegaETH). Through the pre-confirmation mechanism of block sorters, Polymer Hub achieves real-time message delivery, ensuring that cross-chain communication latency can keep pace with the millisecond block generation speed of these Rollups. Additionally, Polymer leverages EigenDA to expand cross-Rollup bandwidth to support on-chain data-intensive application scenarios.
"Real-time capability, the ability to respond to inputs with ultra-low latency in large-scale environments, will lay the foundation for breakthrough developments in decentralized applications. Preparing the relevant infrastructure will be a collective task for the entire industry, and the real-time interoperability provided by Polymer will be key." — Lei Yang (Co-founder and CTO of MegaETH)
Currently, as Ethereum is divided into multiple rollup clusters due to the expansion of shared sorters and interoperability networks, these clusters can achieve interoperability within minutes through Polymer Hub's "one-to-many" architecture, without taking months. Furthermore, Polymer Hub is the first interoperability solution to provide re-org protection, allowing token bridges and solving networks to securely settle cross-chain transactions at millisecond speeds and automatically roll back when these transactions do not align with the historical data of Ethereum L1.
Looking Ahead
The architecture of next-generation on-chain applications will resemble that of cloud applications: Rollups will become the new microservices, while AVS will be the new infrastructure service. To achieve horizontal scaling on-chain, cross-chain infrastructure must have low latency, high bandwidth, and cost-effectiveness.
The Polymer team is committed to enhancing interoperability performance to support the emergence of more high-throughput applications, such as on-chain e-commerce and ride-hailing innovations.
"Building interoperable applications with both low cost and low latency is key to restoring usability in cryptocurrency. In scaled applications, this connection layer needs to be as robust and secure as Ethereum's base layer, and Polymer has made significant efforts to achieve this goal." — Vikram Arun (Co-founder and CEO of Superform Labs)
Starting with the OP stack, Polymer plans to extend real-time interoperability to the entire Ethereum Rollup ecosystem, facilitating rapid and low-cost scaling for applications.
