Steve Newcomb is a Silicon Valley veteran with a protracted checklist of achievements. He constructed software program for buying and selling vitality within the 90s, was a pioneer in including e mail to telephones, and helped create the again finish of the Bing search engine below Peter Thiel’s mentorship. Immediately, 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 examine 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 changing into the de facto “world laptop.” However he describes blockchain as being gradual and cumbersome at the moment because the web was 25 years in the past, so he set to work scaling it as much as at some point to turn 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 Broad Internet’s 25,000 web sites could possibly 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 laptop’ that claims to have the facility to alter the world runs at a grand complete of 15 transactions per second, and we’ve 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 at the very least thirtyfold. “We had SSL, we had HTTPS by then — that little lock icon appeared in our browser. Amazon occurred, Google occurred,” he lists. Immediately, in 2022, there are over 1 billion websites, and speeds over 200 megabits are widespread even on cellular units far superior to something Nokia engineers might 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 purchasing and the secure transmission of personal knowledge — Newcomb is satisfied that “the layer 2s that make crypto safe are the place 10x moments are taking place.”

He identifies 5 sorts 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 sturdy opinions to share.
“For those who assume that the objective 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 just isn’t on Ethereum’s chain,” he states matter-of-factly.
He feels equally about state channels and plasma, arguing that “they simply actually don’t verify the containers.” This leaves solely Optimistic Rollups and zk-Rollups in Newcomb’s good graces. His ardour comes throughout as a somewhat 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 ensure that Ethereum wins. I need 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 reminiscences from the 70s when at 6 years outdated he would solder motherboards along 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 an important factor taking place is, after which take part in that factor in no matter manner they will. Cellphones had been the primary of those grand phenomena.
“After I set out on my profession, I requested myself: Is that this one thing that’s going to have an effect on thousands and thousands of individuals? Is it an enormous deal? Can I add worth indirectly?”
In 2000, Newcomb based LoudFire, an organization that aimed to construct consoles that may management sensible houses, which he describes as an abject failure — “besides that we realized how one can take e mail from a pc and put it in your Nokia cellphone,” which was a revolutionary mixture of two beforehand separate applied sciences. Naturally, the agency was offered 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 offered to turn into a central part of Microsoft’s Bing. He recollects pitching the challenge to investor Thiel by having him sort a search after which asking him to pick out whether or not Google’s outcomes or these from Newcomb’s resolution had 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 premise that it was near a seashore the place he might spend his days “principally ignoring faculty” whereas majoring in accounting.
Within the Nineteen Eighties, he wrote an algorithm to mechanically 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 by way of 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 price of vitality offers per 12 months, and he discovered to code in Object Pascal on the facet with a purpose 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, ultimately being promoted to go of engineering for North America. In 1998, he joined Proxicom, the place he led the manufacturing of buying and selling methods for the vitality sector. By 1999, he was accountable 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 good that no quantum laptop can break it and decentralization so good that no nation-state can cease it — in different phrases, a “non-public web laptop that can’t be hacked by any laptop or stopped by any nation-state.”
“I need individuals to know 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 concentrate on 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 individuals do of their houses?” he asks, describing the encryption of Ethereum as an impenetrable door behind which individuals can commerce and work together freely in such a manner that no authorities, establishment or authority can attain them — a blockchain that runs by itself and is sort of free to make use of.
“In case you have a non-public blockchain and other people determine to do enterprise on it, then governments not have a approach to tax individuals and governments are gone.” Properly, possibly. Historical past is being made a technique or one other, and Newcomb is doing his finest to be a part of it.
Rating rollups
So, what are these rollups to start with, and why are they higher, in keeping with Newcomb?
In response to Ledger Academy:
“Rollups ‘roll up’ or compile a bunch of transactions and switch them into one single knowledge 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 knowledge, and submit them again to the Ethereum mainnet. That is why rollups are additionally referred to as ‘off-chain scaling options.’”

There are two main sorts: Optimistic Rollups and zk-Rollups.
In response to Newcomb, Optimistic Rollups, as utilized by Optimism and Arbitrum, in the end rely on a classy sport idea, which successfully permits everybody to make use of the blockchain. “After which, after the very fact, they verify to ensure that there isn’t any fraud.”
With this technique, “you may be possibly 99.999% certain there’s no fraud, however you’ll be able to’t be 100%. It’s the easiest sport idea we’ve, 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 occasions 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, then again, “verify for fraud utilizing arithmetic — one thing referred to as a ZK proof that isn’t 99.999% correct. It doesn’t use sport idea. It’s actually mathematically good.” There are competing zk-Rollup layer 2s from ConsenSys, StarkNet and Polygon.
Clearly, they’re Newcomb’s most popular 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 might stand up to thousands and thousands of transactions per second, making this an actual web laptop, and we might achieve this whereas completely sustaining safety.”
Zk-Rollups will not be a singular challenge however a technical resolution being labored on by numerous separate groups. Of those, Newcomb lists his high 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 by way of a five-point checklist of “magic elements” he believes are wanted for a ZK resolution to be adopted.
5 factors
Firstly, an L2 resolution ought to be “basic objective,” that means that any DApp or sensible contract might be constructed to work together with it, versus accommodating solely particular use instances akin to NFTs.
Secondly, the answer ought to be EVM-compatible, that 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 totally different and are examples of non-EVM suitable chains.
Thirdly, the answer ought to assist 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 turn into riled up towards you, as it could not match the ethos.”
Lastly, Newcomb emphasizes that there should be a plan for tokenization that advantages the ecosystem: “Two-thirds of your tokens ought to be devoted to the advantage of the ecosystem, to not the advantage of the shareholders of the unique firm constructing the layer-2 resolution.”
“The precise finest case is that ZK turns into a typical. That’s why we open-sourced it, in order that it could turn 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 heart stage within the coming years, what Newcomb appears to be like 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.”
