Steve Newcomb is a Silicon Valley veteran with a protracted listing 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. Right now, 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 changing into the de facto “world pc.” However he describes blockchain as being gradual and cumbersome at present because the web was 25 years in the past, so he set to work scaling it as much as at some point to develop 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 much like that of the web in 1995, when the World Huge Internet’s 25,000 web sites might 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 facility to alter the world runs at a grand complete of 15 transactions per second, and we now have 4,000 legit 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. Right now, in 2022, there are over 1 billion websites, and speeds over 200 megabits are widespread even on cellular gadgets far superior to something Nokia engineers may have even dreamed of 20 years in the past.
Identical to the appearance 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 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 sturdy opinions to share.
“In case you suppose that the purpose 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 simply actually don’t examine the packing containers.” This leaves solely Optimistic Rollups and zk-Rollups in Newcomb’s good graces. His ardour comes throughout as a relatively 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 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 need to be within the room when it occurs.”
No stranger to expertise, 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 suppose an important factor occurring is, after which take part in that factor in no matter means 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 ultimately?”
In 2000, Newcomb based LoudFire, an organization that aimed to construct consoles that might management good properties, which he describes as an abject failure — “besides that we realized the way to take electronic 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 bought 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 bought to develop into a central part of Microsoft’s Bing. He remembers pitching the challenge 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 had been higher. “He selected us 70% over Google,” Newcomb remembers, 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 seaside the place he may spend his days “principally ignoring college” 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 through 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 value of vitality offers per yr, and he realized 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, 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 techniques for the vitality sector. By 1999, he was answerable 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 top recreation 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 “personal web pc that can’t be hacked by any pc or stopped by any nation-state.”
“I would like 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 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 properties?” he asks, describing the encryption of Ethereum as an impenetrable door behind which individuals can commerce and work together freely in such a means 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 other people determine to do enterprise on it, then governments not have a option to tax individuals and governments are gone.” Properly, perhaps. Historical past is being made a method or one other, and Newcomb is doing his greatest to be a part of it.
So, what are these rollups to start with, and why are they higher, in response to 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. This is the reason rollups are additionally referred to as ‘off-chain scaling options.’”
Essentially the most partaking reads in blockchain. Delivered as soon as a
There are two main sorts: Optimistic Rollups and zk-Rollups.
In line with Newcomb, Optimistic Rollups, as utilized by Optimism and Arbitrum, finally rely upon a classy recreation idea, which successfully permits everybody to make use of the blockchain. “After which, after the very fact, they examine to ensure that there isn’t a fraud.”
With this technique, “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 issues 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, however, “examine for fraud utilizing arithmetic — one thing referred to as a ZK proof that isn’t 99.999% correct. It doesn’t use recreation idea. 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 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 rise up to thousands and thousands of transactions per second, making this an actual web pc, and we may achieve this 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 through a five-point listing of “magic substances” he believes are wanted for a ZK resolution to be adopted.
Firstly, an L2 resolution needs to be “common objective,” which means that any DApp or good contract will be constructed to work together with it, versus accommodating solely particular use instances comparable to NFTs.
Secondly, the answer needs to be EVM-compatible, which means that like with BNB Chain, Polygon, Solana and Avalanche, Ethereum tasks will be simply ported over. Bitcoin, Monero, Litecoin, Cardano and XRP Ledger are completely completely different and are examples of non-EVM appropriate chains.
Fourthly, a ZK-proof resolution must be open-source, “or the group of crypto will develop 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 needs 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 greatest case is that ZK turns into a regular. That’s why we open-sourced it, in order that it may possibly develop 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 seems 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 discuss them after. We get to see progress reside on-chain.”
