‘​​The Polyverse Testnet’ is live, bringing IBC to Ethereum

Polymer, an Ethereum rollup that’s hoping to turn out to be Ethereum’s interoperability hub, has launched the Polyverse Testnet, changing into the most recent crew hoping to sort out blockchain interoperability.

The testnet will likely be launched in three phases dubbed ‘Basecamp,’ ‘Into the Unknown’ and ‘Discovery.’ The primary part, Basecamp, will likely be reside beginning right this moment and is designed to incentivize builders to facilitate liquidity onto the testnet from different rollups.

Section 2, Into the Unknown, will begin the next week, the place Polymer will choose a handful of decentralized apps to advertise to finish customers, who may also be capable of obtain rewards. Then the ultimate part, Discovery, will deal with refining and optimizing incentive mechanisms to drive participation.

The blockchain interoperability downside

Like many cross-chain messaging and bridging protocols right this moment, Polymer was created to unravel the problem of blockchain interoperability.

Blockchain ecosystems right this moment stay comparatively remoted from each other, that means they can’t talk or work together with one another — creating horrible person experiences for his or her clients.

An instance of this in Web2 could be being unable to ship emails out of your Gmail account to an Outlook account.

To handle the communication barrier, cross-chain messaging protocols and different interoperability options have sprung into life as a way to allow blockchains to soundly switch useful info to one another.

The sort of infrastructure is important to blockchain scaling, as evidenced by the eye and curiosity it has obtained from traders.

Wormhole, one of many largest cross-chain messaging options right this moment, secured $225 million in a non-public token sale, which noticed curiosity from Brevan Howard, Coinbase Ventures and Multicoin Capital late final 12 months.

Equally, LayerZero locked in a seven-figure Sequence B fundraise, the place traders from a16z, OKX Ventures and Sequoia Capital gave the protocol $120 million to develop its operations.

Polymer additionally lately revealed that it acquired $23 million to convey Cosmos SDK’s inter-blockchain communication (IBC) protocol to Ethereum.

Polymer’s approaches to interoperability

Not like many interoperability protocols right this moment, Polymer will not be designed as a third-party bridge however relatively as a layer-2 Ethereum rollup answer that serves an analogous goal to the ‘interoperability hub’ on Cosmos. It goals to offer IBC to Ethereum and join with different layer-2 options.

IBC, in contrast to many different interoperability options right this moment, will not be a bridge utility however a community commonplace, Devain Pal Bansal, a product analyst at Polymer Labs, advised Blockworks.

“The most important advantage of introducing it to Ethereum, notably Ethereum rollups, is that it extends the capabilities of how a rollup settles on Ethereum by way of the native bridge and extends it cross rollups – with no third celebration required to attest to knowledge or its validity by merely utilizing the shared supply of reality for all rollups – Ethereum,’ Bansal stated.

Tommy O’Connell, a senior product supervisor at Polymer, defined to Blockworks that purposes can construct their very own bridges and management inbound and outbound messages utilizing a layer-1 belief layer. This eliminates the necessity for a further belief assumption of a 3rd celebration.

“This additionally permits us to be centered on enabling chains to hitch Polymer’s ecosystem of chains with only a SINGLE connection to the hub, mitigating Polymer being a blocker for progress,” O’Connell stated.

This differs from Wormhole, for instance, which depends on a 13 of 19 supermajority to attest to a message earlier than it’s produced or despatched. Additionally it is completely different from Axelar, which depends on validators for attestations.

You will need to observe, nonetheless, that Polymer’s minimal viable product (MVP) will likely be restricted to the Base and Optimism on the testnet launch.

Although that is the case, O’Connell notes that there are rapid plans to develop to different OP stack chains and shortly after to different chains similar to these within the Cosmos ecosystem.

“The first profit for OP stack rollups is that now we have constructed an IBC consumer for OP geth, which allows us to increase the capabilities of native L1<>L2 bridge throughout rollups. It’s notably interesting as a result of we will unlock different chains constructed on the OP stack with minimal growth effort,” O’Connell stated.
