Measuring Each Other’s Rollups
Money, technological progress, personal ambitions and achievements. There’s a whole lot at stake as new EVM-compatible zk-rollup blockchains vye for market share, development and users.
It’s probably not a surprise that, in these exciting and formative times for zkEVM, disagreements and discussions among leaders of competing projects have spilled out into the public arena.
In the past few days, leaders of Polygon zkEVM, zkSync Era and Scroll have been engaging with one another on Twitter, variously taking issue with claims about their projects, disputing characterizations of others’, and attempting to diffuse the perceived tension with peacemaking remarks.
Polygon Zero Co-Founder Brendan Farmer tussled with Alex Gluchowski, Co-Founder and CEO of zkSync creator Matter Labs over relative efficiency and gas costs.
ZK wars are already spicy and full of FUD. Per @jbaylina, the accurate numbers are 2.27m gas for 1116 transactions, so the difference in efficiency is... basically zero. https://t.co/0h9GWbAVQA

Then, fellow Polygon Zero Co-Founder Daniel Lubarov published an article attempting to “clarify some facts about Polygon zkEVM and how it compares to others.”
The article mainly compares Polygon zkEVM to zkSync Era, in regard to EVM compatibility, performance and security.
Gluchowski took issue with Lubarov’s analysis, calling it “extremely biased and misleading.”
He said, “The honest way to do a credibly neutral comparison is to reach out to the other party *before* you publish. Otherwise it's a marketing brochure.”
With the "ZK wars" heating up, there's been a lot of discussion about the merits of each zkEVM, and a few misconceptions. I wrote a post which I hope will clarify things: https://t.co/9mH8I3ztER

In the meantime, Farmer posted a separate Twitter thread parsing the difference between EVM-compatibility and EVM-equivalence, saying that definitions are arbitrary but arguing that Polygon zkEVM is EVM-equivalent for nearly 100% of smart contracts on the layer-1 Ethereum blockchain.
He then brought up a December 2022 comment from Scroll Senior Researcher Toghrul Maharramov, who had said Polygon’s rollup was “not a zkEVM.”
Keep in mind, I'm biased - I work at @0xPolygonLabs!

But also keep in mind that there's a vested interest in modifying definitions to benefit different agendas. Not to pick on Toghrul, whom I respect, but as of last year, we weren't even a zkEVM!https://t.co/mtFm5lcGzO

Polygon Labs President Ryan Watt made a Twitter post saying that, compared to his experience at Google, Web3 is a much smaller arena and projects need to “think bigger and more collaboratively.”
Scroll Co-Founder Sandy Peng retweeted Watt’s post with praise for Polygon’s product and marketing.
In all seriousness we are all still small. Polygon has consistently pushed the boundaries on both what their zk teams achieved in the form of product, and the marketing team achieved in terms of gaining popular mindshare. We have a lot to learn across the board. https://t.co/cs6bAKOqX1

Fellow Scroll Co-Founder Ye Zhang tweeted her agreement, saying that there was more smoke than fire in the recent “spicy” Twitter arguments among the competing zkEVM projects.
Although it looks spicy on twitter, @_bfarmer @dlubarov @jbaylina are very friendly and collaborative! Amazing progress has been made to prover acceleration and zkEVM engineering.
