Steve Newcomb is a Silicon Valley veteran with an extended record of achievements. He constructed software program for buying and selling vitality within the 90s, was a pioneer in including electronic mail to telephones, and helped create the again finish of the Bing search engine beneath Peter Thiel’s mentorship. At present, he heads up growth for Berlin-based Matter Labs, which is constructing scaling options for Ethereum.
“I used to be very a lot a skeptic” when it got here to cryptocurrency and blockchain, explains Newcomb, zkSync’s chief product officer. He provides that it took two years of research earlier than he understood the subject and the advantages to his satisfaction.
Calculating that Ethereum had a 65% market share of the layer-1 market, Newcomb was satisfied that it held the best promise in turning into the de facto “world pc.” However he describes blockchain as being gradual and cumbersome at this time because the web was 25 years in the past, so he set to work scaling it as much as sooner or later to change into as quick as Web2 is now.
Layer 2s to the rescue
As a veteran of the dot-com period, Newcomb sees the present state of the blockchain atmosphere — not simply Ethereum — as just like that of the web in 1995, when the World Extensive Internet’s 25,000 web sites may very well be accessed by common dial-up speeds of lower than 30 kilobits per second.
“It’s gradual as molasses. Our very well-known ‘Ethereum web pc’ that claims to have the ability to vary the world runs at a grand complete of 15 transactions per second, and now we have 4,000 respectable tasks on Ethereum — very, similar to 1995.”
Simply 10 years later in 2005, web sites numbered over 100 million, and speeds had elevated no less than thirtyfold. “We had SSL, we had HTTPS by then — that little lock icon appeared in our browser. Amazon occurred, Google occurred,” he lists. At present, in 2022, there are over 1 billion websites, and speeds over 200 megabits are frequent even on cellular units far superior to something Nokia engineers may have even dreamed of 20 years in the past.
Identical to the arrival of SSL and HTTPS, which made the web safe — permitting for on-line buying and the protected transmission of personal information — Newcomb is satisfied that “the layer 2s that make crypto safe are the place 10x moments are occurring.”

He identifies 5 varieties of layer-2 options: state channels (Raiden Community, Perun), plasma (Plasma Money, Plasma MVP), sidechains (Skale, Gnosis, Loom), Optimistic Rollups (Arbitrum, Optimism, Boba), and zero-knowledge rollups (Scroll, Matter). Newcomb has some robust opinions to share.
“Should you assume that the aim of layer 2s is to scale Ethereum whereas sustaining its decentralization and safety, sidechains don’t obtain this. They’ve far much less safety than Ethereum does, as a result of their purposeful chain will not be on Ethereum’s chain,” he states matter-of-factly.
He feels equally about state channels and plasma, arguing that “they simply actually don’t examine the containers.” This leaves solely Optimistic Rollups and zk-Rollups in Newcomb’s good graces. His ardour comes throughout as a reasonably assertive, maybe unfair, dismissal of a good portion of the layer-2 panorama — however let’s save that dialogue for a future article.
“My mission is to be sure that Ethereum wins. I would like it to be the primary that will get it to go from 15 to 1,000 or 10 million transactions per second. I wish to be within the room when it occurs.”
Serial founder
No stranger to know-how, Newcomb has fond recollections from the 70s when at 6 years previous he would solder motherboards together with his father, who “labored for an company I can’t identify.” He describes a need from an early age to be a part of historical past, which propelled him in his profession. In his view, one ought to discover out what they assume a very powerful factor occurring is, after which take part in that factor in no matter method they’ll. Cellphones have been the primary of those grand phenomena.
“Once I set out on my profession, I requested myself: Is that this one thing that’s going to have an effect on hundreds of thousands of individuals? Is it a giant deal? Can I add worth ultimately?”
In 2000, Newcomb based LoudFire, an organization that aimed to construct consoles that might management sensible properties, which he describes as an abject failure — “besides that we realized tips on how to take electronic mail from a pc and put it in your Nokia telephone,” which was a revolutionary mixture of two beforehand separate applied sciences. Naturally, the agency was bought to Nokia in 2002, which was the pre-iPhone juggernaut dominating the cell phone business on the time.
In 2008, he based Powerset, a pure language search engine that was basically bought to change into a central part of Microsoft’s Bing. He recollects pitching the undertaking to investor Thiel by having him kind a search after which asking him to pick whether or not Google’s outcomes or these from Newcomb’s resolution have been higher. “He selected us 70% over Google,” Newcomb recollects, after which he promptly had $800,000 within the financial institution and a brand new mentor.
“Two of my junior engineers break up off to create a small firm referred to as GitHub,” he remarks.
Jingles and resumes
Newcomb describes himself as having been one thing of a troublemaker rising up, making use of to Salisbury College in Maryland on the idea that it was near a seaside the place he may spend his days “principally ignoring college” whereas majoring in accounting.
Within the Nineteen Eighties, he wrote an algorithm to routinely generate the scripts for used automobile dealerships’ TV and radio commercials with “tacky music and a few tacky gross sales man,” charging 1000’s a pop. His second enterprise whereas in college was successfully a pre-internet model of LinkedIn, charging college students to distribute their resumes to different universities throughout the area through a system of interconnected printers.
Upon graduating, Newcomb joined the vitality firm Statoil in 1993, reasoning that it appeared like an essential business to get into, because the U.S. authorities had simply deregulated the vitality markets. At simply 21, he says he was buying and selling $600 million value of vitality offers per 12 months, and he realized to code in Object Pascal on the aspect with a view to make his job simpler by automation and simpler management.
As the corporate started utilizing his software program to commerce billions in annual quantity, Newcomb says he realized the true energy of coding and fell in love with software program, finally being promoted to go of engineering for North America. In 1998, he joined Proxicom, the place he led the manufacturing of buying and selling techniques for the vitality sector. By 1999, he was chargeable for AT&T’s web and streaming video technique.

The impenetrable door
Together with his historical past as witness, Newcomb doesn’t assume small. For him, the top sport of Ethereum is safety so excellent that no quantum pc can break it and decentralization so good that no nation-state can cease it — in different phrases, a “non-public web pc that can not be hacked by any pc or stopped by any nation-state.”
“I would like folks to grasp that that is extra essential than know-how; that is probably as essential as what comes after capitalism and democracy,” he says. He elaborates that when a brand new know-how comes alongside, it usually replaces an incumbent, as when iPhone changed Nokia.
“What’s the incumbent that blockchain replaces? If you consider it, it’s authorities.”
If that’s true, there’s a determined want for adults within the room, and Newcomb quips that he’s lastly sufficiently old to be thought of one. “Think about we constructed a door that may by no means be knocked down. What would folks do of their properties?” he asks, describing the encryption of Ethereum as an impenetrable door behind which individuals can commerce and work together freely in such a method that no authorities, establishment or authority can attain them — a blockchain that runs by itself and is sort of free to make use of.
“If in case you have a non-public blockchain and folks resolve to do enterprise on it, then governments now not have a approach to tax folks and governments are gone.” Nicely, possibly. Historical past is being made a technique or one other, and Newcomb is doing his greatest to be a part of it.
Rating rollups
So, what are these rollups to start with, and why are they higher, in response to Newcomb?
In line with Ledger Academy:
“Rollups ‘roll up’ or compile a bunch of transactions and switch them into one single information and submit it to the Ethereum mainnet. They take the transactions out of the mainnet and course of them off-chain, convert them into one single piece of information, and submit them again to the Ethereum mainnet. For this reason rollups are additionally referred to as ‘off-chain scaling options.’”

There are two main sorts: Optimistic Rollups and zk-Rollups.
In line with Newcomb, Optimistic Rollups, as utilized by Optimism and Arbitrum, finally rely on a classy sport concept, which successfully permits everybody to make use of the blockchain. “After which, after the very fact, they examine to be sure that there is no such thing as a fraud.”
With this technique, “you can be possibly 99.999% certain there’s no fraud, however you possibly can’t be 100%. It’s the easiest sport concept now we have, and it does scale Ethereum by an element of seven, possibly as much as 10.” Although he concedes that it passes as a scaling resolution, Newcomb expresses considerations about settlement instances at elevated ranges of scaling, describing the method as more and more “hairier” and saying that he “couldn’t perceive the way it scales past the unique 10x.”
Zk-Rollups, alternatively, “examine for fraud utilizing arithmetic — one thing referred to as a ZK proof that isn’t 99.999% correct. It doesn’t use sport concept. It’s actually mathematically excellent.” There are competing zk-Rollup layer 2s from ConsenSys, StarkNet and Polygon.
Clearly, they’re Newcomb’s most well-liked resolution, one which he says was beforehand considered too costly and 10 years away from efficient implementation — however “we’ve solved these issues a lot quicker than anybody predicted.”
“Zk-Rollups, for me, represented each scale and safety mixed at limitless scale. We theoretically may rise up to hundreds of thousands of transactions per second, making this an actual web pc, and we may accomplish that whereas completely sustaining safety.”
Zk-Rollups usually are not a singular undertaking however a technical resolution being labored on by varied separate groups. Of those, Newcomb lists his prime three (engaged on EVM-compatible options): Matter, Scroll and Polygon. He considers Matter, which he works for, to be 9 to 12 months forward of Scroll and Polygon, with different options being roughly one to 2 years behind — a view he has arrived at through a five-point record of “magic elements” he believes are wanted for a ZK resolution to be adopted.
5 factors
Firstly, an L2 resolution must be “basic goal,” which means that any DApp or sensible contract might be constructed to work together with it, versus accommodating solely particular use circumstances similar to NFTs.
Secondly, the answer must be EVM-compatible, which means that like with BNB Chain, Polygon, Solana and Avalanche, Ethereum tasks might be simply ported over. Bitcoin, Monero, Litecoin, Cardano and XRP Ledger are completely completely different and are examples of non-EVM suitable chains.
Thirdly, the answer ought to help Solidity, the programming language used to develop sensible contracts on Ethereum. “Supporting JavaScript for the online equals supporting Solidity for crypto,” Newcomb causes.
Fourthly, a ZK-proof resolution must be open-source, “or the neighborhood of crypto will change into riled up in opposition to you, as it will not match the ethos.”
Lastly, Newcomb emphasizes that there should be a plan for tokenization that advantages the ecosystem: “Two-thirds of your tokens must be devoted to the good thing about the ecosystem, to not the good thing about the shareholders of the unique firm constructing the layer-2 resolution.”
“The precise greatest case is that ZK turns into an ordinary. That’s why we open-sourced it, in order that it may possibly change into a public good. Our hope sooner or later is that there aren’t any different protocols — it’s simply the protocol.”
No matter layer-2 resolution(s) find yourself taking middle stage within the coming years, what Newcomb seems to be ahead to most is the general public nature of progress that’s inherent to blockchain versus earlier eras of technological growth. “Engineers used to see issues privately and speak about them after. We get to see progress dwell on-chain.”
