Polygon’s ‘holy grail’ Ethereum scaling zkEVM beta hits mainnet

Polygon has launched its open-source zkEVM Ethereum (ETH) scaling know-how to the mainnet, promising lowered transaction prices and elevated throughput of good contract deployments.

Polygon’s zkEVM is a zero-knowledge rollup (ZK-rollups) scaling resolution equal to the Ethereum Digital Machine. ZK-rollups improve throughput on Ethereum’s blockchain by batching computations and state storage to layer-2 platforms. The know-how permits hundreds of transactions to be batched off-chain, with a proof containing a minimal information abstract posted to the Ethereum mainnet.

Polygon’s zkEVM is a kind of ZK-rollup that mimics the transaction execution atmosphere of Ethereum’s mainnet. The open-source zkEVM is touted to permit decentralized purposes (DApps) to scale via transaction batching, unlocking increased efficiency.

Fuel charges are additionally set to be lowered for DApp customers, which might drive wider adoption, whereas the usage of zero-knowledge proofs sees Polygon zkEVM inherit Ethereum’s community safety. Lastly, equivalence with Ethereum implies that builders can merely copy throughout present good contracts to Polygon’s zkEVM.

Cointelegraph spoke to Polygon co-founder Sandeep Nailwal forward of the mainnet beta launch to unpack the importance of the milestone, and the anticipated impact zkEVM could have on the broader Ethereum ecosystem.

Nailwal described ZK proofs as ‘the holy grail of Ethereum scaling,’ permitting the layer 1 blockchain to easily confirm a submitted proof with out having to re-run computations:

“Think about you computed an entire enterprise transaction some other place off-chain on layer 2, however on Ethereum, you submitted a really succinct proof and Ethereum 200% is aware of that you simply computed it appropriately.”

ZK-rollups are additionally set to make optimistic rollups out of date, in keeping with Nailwal. The Ethereum blockchain primarily assumes optimistic rollups are submitting appropriate computations whereas a community participant verifies the small print of the transaction. That is a part of the rationale optimistic rollups on layer 2 have a seven-day withdrawal interval:

“That is why it is a sport changer. The group is aware of that optimistic rollups are like crutches earlier than Ethereum found out ZK. And now that ZK is there, it sort of makes optimistic rollups out of date. That is the tip sport principally.”

Nailwal says the arrival of ZK-rollups implies that future improvement of the Ethereum ecosystem can give attention to consumer expertise, elevated scalability and simpler proving to ‘open up the floodgates’ for wider use.

Whereas the zkEVM has been launched to mainnet beta, Nailwal careworn that the know-how is ultimately state of the product. The zkEVM will proceed to be optimized as customers improve and bug bounties, and additional audits might be carried out over the subsequent couple of months.

Cointelegraph additionally queried whether or not ZK-rollups have introduced the Ethereum ecosystem nearer to fixing the so-called blockchain trilemma coined by co-founder Vitalik Buterin.

“It is extremely shut, truly. The blockchain trilemma says out of safety, decentralization and scalability, you may select solely two. What you might be doing is getting scalability some other place, computing one thing and getting the safety and decentralization from Ethereum.”

Buterin was additionally concerned within the launch of Polygon’s zkEVM on March 27, finishing up the primary consumer transaction. Nailwal described the gesture as symbolic, given Buterin’s ongoing affect within the improvement of Ethereum.
