Healthy competition welcome — Polygon zkEVM lead – Cointelegraph


Prominent Ethereum development firms have rolled out varying zero-knowledge scaling solutions that drive healthy competition in the ecosystem.
An environment of healthy competition is being fostered between the Ethereum ecosystem’s top development firms building zero-knowledge Ethereum Virtual Machines (zkEVMs) to scale the network, according to one of Polygon’s co-founders.
Jordi Baylina, technical lead of Polygon Hermez zkEVM, spoke to Cointelegraph ahead of the start of EthCC in France. With builders from across the Ethereum ecosystem converging on Paris, zero-knowledge proof (ZK-proof) scaling tools are set to be a major focal point.
Polygon’s zkEVM uses ZK-proofs to reduce transaction costs and increase the throughput of the Ethereum network, while taking advantage of the security and finality of the layer-1 blockchain.
ZK-proofs have proved to be an important scaling tool for the Ethereum ecosystem. The technology allows protocols like Polygon’s zkEVM to handle transaction computations off-chain before providing a resource-lite proof to the Ethereum mainnet without revealing any of the associated data.

Baylina, who is at the helm of Polygon’s zkEVM, says the breadth of development being done with ZK technology has been hugely beneficial to the wider Ethereum ecosystem:
Baylina added that various projects emulate good advances and try to make them better, while failings act as a learning for all ZK-based projects in the space.
Polygon zkEVM is live on mainnet, and the network is closing in on 250,000 unique active addresses. Its daily active Polygon zkEVM addresses are also trending upward, with both metrics suggesting that user adoption is growing.

Meanwhile, Baylina highlighted the number of applications that are building on Polygon zkEVM as the most important metric for his team. This, in turn, leads to a wealth of information and feedback from developers, which is shaping changes to the protocol:
Baylina provided a working example where developers had identified issues with timestamps that were critical for the operation of decentralized finance oracles. Bayina’s team found a workaround solution while a long-term fix was being developed. Nevertheless, the input from builders is helping improve the protocol as more join the ecosystem.
Polygon co-founder Sandeep Nailwal previously told Cointelegraph that Polygon’s zkEVM is the “holy grail of Ethereum scaling,” allowing the protocol to submit proofs to the Ethereum mainnet without the layer-1 blockchain having to rerun computations. 
The technology is envisioned to drastically scale Ethereum, allowing developers to build decentralized applications while being unencumbered by the base blockchain’s network performance.
