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 underneath Peter Thiel’s mentorship. At this time, he heads up improvement 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 sluggish and cumbersome right this moment because the web was 25 years in the past, so he set to work scaling it as much as at some point 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 surroundings — not simply Ethereum — as just like that of the web in 1995, when the World Broad Net’s 25,000 web sites might be accessed by common dial-up speeds of lower than 30 kilobits per second.
“It’s sluggish as molasses. Our very well-known ‘Ethereum web pc’ that claims to have the facility to alter the world runs at a grand complete of 15 transactions per second, and we now have 4,000 reputable initiatives on Ethereum — very, similar to 1995.”
Simply 10 years later in 2005, web sites numbered over 100 million, and speeds had elevated a minimum of thirtyfold. “We had SSL, we had HTTPS by then — that little lock icon appeared in our browser. Amazon occurred, Google occurred,” he lists. At this time, in 2022, there are over 1 billion websites, and speeds over 200 megabits are widespread even on cell units far superior to something Nokia engineers may have even dreamed of 20 years in the past.
Similar to the arrival of SSL and HTTPS, which made the web safe — permitting for on-line buying and the secure 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 kinds 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 suppose 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 useful chain will not be on Ethereum’s chain,” he states matter-of-factly.
He feels equally about state channels and plasma, arguing that “they only actually don’t test the containers.” This leaves solely Optimistic Rollups and zk-Rollups in Newcomb’s good graces. His ardour comes throughout as a slightly 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 need to be within the room when it occurs.”
No stranger to expertise, Newcomb has fond recollections from the 70s when at 6 years outdated he would solder motherboards together with his father, who “labored for an company I can’t title.” 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 suppose a very powerful factor occurring is, after which take part in that factor in no matter approach they’ll. Cellphones have 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 tens of millions of individuals? Is it a giant deal? Can I add worth in a roundabout way?”
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 the way to take e-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 offered to Nokia in 2002, which was the pre-iPhone juggernaut dominating the cell phone trade on the time.
In 2008, he based Powerset, a pure language search engine that was primarily offered to change into a central element 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 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 cut up off to create a small firm known 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 “largely ignoring faculty” whereas majoring in accounting.
Within the 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 hundreds 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 necessary trade 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 yr, and he discovered to code in Object Pascal on the aspect so as 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 move of engineering for North America. In 1998, he joined Proxicom, the place he led the manufacturing of buying and selling programs for the vitality sector. By 1999, he was accountable for AT&T’s web and streaming video technique.

The impenetrable door
Along with his historical past as witness, Newcomb doesn’t suppose small. For him, the tip recreation of Ethereum is safety so good 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’t be hacked by any pc or stopped by any nation-state.”
“I need individuals to know that that is extra necessary than expertise; that is probably as necessary as what comes after capitalism and democracy,” he says. He elaborates that when a brand new expertise 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 individuals 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 approach that no authorities, establishment or authority can attain them — a blockchain that runs by itself and is nearly free to make use of.
“If in case you have a non-public blockchain and other people resolve to do enterprise on it, then governments now not have a option to tax individuals and governments are gone.” Effectively, perhaps. Historical past is being made a technique or one other, and Newcomb is doing his finest to be a part of it.
So, what are these rollups to start with, and why are they higher, in line with Newcomb?
According to 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 knowledge, and submit them again to the Ethereum mainnet. Because of this rollups are additionally known as ‘off-chain scaling options.’”
Essentially the most participating reads in blockchain. Delivered as soon as a
There are two major sorts: Optimistic Rollups and zk-Rollups.
In accordance with Newcomb, Optimistic Rollups, as utilized by Optimism and Arbitrum, in the end rely upon a complicated recreation idea, which successfully permits everybody to make use of the blockchain. “After which, after the actual fact, they test to ensure that there is no such thing as a fraud.”
With this method, “you could possibly be perhaps 99.999% positive there’s no fraud, however you may’t be 100%. It’s the easiest recreation idea we now have, and it does scale Ethereum by an element of seven, perhaps 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, “test for fraud utilizing arithmetic — one thing known as a ZK proof that isn’t 99.999% correct. It doesn’t use recreation 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 regarded as 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 stand up to tens of millions of transactions per second, making this an actual web pc, and we may accomplish that whereas completely sustaining safety.”
Zk-Rollups will not be a singular challenge 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 by way of a five-point checklist of “magic substances” he believes are wanted for a ZK resolution to be adopted.
Firstly, an L2 resolution ought to be “normal function,” that means that any DApp or sensible contract could be constructed to work together with it, versus accommodating solely particular use circumstances equivalent to NFTs.
Secondly, the answer ought to be EVM-compatible, that means that like with BNB Chain, Polygon, Solana and Avalanche, Ethereum initiatives could be simply ported over. Bitcoin, Monero, Litecoin, Cardano and XRP Ledger are completely totally different and are examples of non-EVM suitable chains.
Fourthly, a ZK-proof resolution must be open-source, “or the group of crypto will change into riled up in opposition to you, as it might 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 good thing about the ecosystem, to not the good thing about the shareholders of the unique firm constructing the layer-2 resolution.”
“The precise finest case is that ZK turns into a regular. That’s why we open-sourced it, in order that it might 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 ahead to most is the general public nature of progress that’s inherent to blockchain versus earlier eras of technological improvement. “Engineers used to see issues privately and discuss them after. We get to see progress dwell on-chain.”
