🚀 Crypto Polymer Officially Launches Real-Time Interoperability Protocol For Ethereum Rollups

Polymer Labs has launched a real-time interoperability protocol for connecting all Ethereum rollups, known as Polymer Hub.

The new protocol verifies and stores the headers of all connected rollups by streaming messages, states, and logs over IBC primitives (equivalent to Web2’s TCP/IP). This allows it to prove any arbitrary state across rollups at a low cost.

Before now, Rollup/L2 ecosystems were connected only within their walled gardens. Polymer Hub changes this by enabling communication across ecosystems and coordinates as fast as they can produce blocks.

Some of the protocol’s most significant improvements are in cross-chain communication latency, bandwidth, and cost for all on-chain primitives compared to existing solutions. Polymer also intends to make cross-chain interoperability as fast, efficient, and affordable as block space itself, enabling Ethereum applications to scale to the next million users through the protocol.

The most significant of these improvements is in reducing latency and increasing bandwidth. Current interoperability protocols were not designed to support dense network traffic across hundreds of rollups because they are too slow and expensive.

The goal is to build interoperability solutions that complement the speed and efficiency of next-generation Ethereum applications. Polymer aims to support this by building the fastest and most efficient interoperability protocol for next-generation rollups like MegaETH.

Polymer Hub passes messages in real time via sequencer pre-confirmations, ensuring that cross-chain communication latency can keep up with the rollups’ millisecond block times. It also leverages EigenDA to scale cross-rollup bandwidth to facilitate data-intensive use cases on the chain.

Commenting on the new protocol, Lei Yang, Cofounder & CTO MegaETH, said:

“Real-timeness, the ability to react to inputs with ultra-low latency at massive scale, will enable truly ground-breaking decentralized applications. Readying the infra stack for this revolution will be a joint effort, in which real-time interoperability from Polymer will be crucial.”

Notably, Polymer is the first interoperability solution to offer re-org protection, which enables token bridges and solver networks to safely settle cross-chain transactions in milliseconds and automatically revert them if they deviate from Ethereum’s L1 history.

In the near future, Polymer plans to bring real-time interoperability to all rollup ecosystems on Ethereum—enabling swift and cost-effective scaling for applications, starting with the OP stack.
