Polygon has launched its open-source zkEVM Ethereum (ETH) scaling expertise to the mainnet, promising decreased transaction prices and elevated throughput of sensible contract deployments.
Polygon’s zkEVM is a zero-knowledge rollup (ZK-rollups) scaling resolution equal to the Ethereum Digital Machine. ZK-rollups enhance throughput on Ethereum’s blockchain by batching computations and state storage to layer-2 platforms. The expertise permits hundreds of transactions to be batched off-chain, with a proof containing a minimal knowledge abstract posted to the Ethereum mainnet.
Polygon’s zkEVM is a sort of ZK-rollup that mimics the transaction execution surroundings of Ethereum’s mainnet. The open-source zkEVM is touted to permit decentralized purposes (DApps) to scale by transaction batching, unlocking increased efficiency.
Fuel charges are additionally set to be decreased for DApp customers, which may drive wider adoption, whereas using zero-knowledge proofs sees Polygon zkEVM inherit Ethereum’s community safety. Lastly, equivalence with Ethereum signifies that builders can merely copy throughout present sensible 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 may have on the broader Ethereum ecosystem.
twenty seventh March 2023 will change Ethereum scaling for ever.
What does a “zkEVM Mainnet” imply?
1. EVM Equivalence
2. Totally carried out and printed audits
3. Public entry to all builders, builders and customers

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 a complete enterprise transaction elsewhere 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 accurately.”
ZK-rollups are additionally set to make optimistic rollups out of date, in accordance with Nailwal. The Ethereum blockchain basically assumes optimistic rollups are submitting appropriate computations whereas a community participant verifies the small print of the transaction. That is a part of the explanation optimistic rollups on layer 2 have a seven-day withdrawal interval:
“That is why it is a recreation changer. The neighborhood is aware of that optimistic rollups are like crutches earlier than Ethereum found out ZK. And now that ZK is there, it form of makes optimistic rollups out of date. That is the top recreation mainly.”
Nailwal says the arrival of ZK-rollups signifies that future growth of the Ethereum ecosystem can deal with 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 expertise is in the long run state of the product. The zkEVM will proceed to be optimized as customers enhance and bug bounties, and additional audits will likely be carried out over the following 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, really. The blockchain trilemma says out of safety, decentralization and scalability, you may select solely two. What you might be doing is getting scalability elsewhere, 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 growth of Ethereum.
