‘Make sure Ethereum wins’ — Steve Newcomb reveals zkSync’s prime directive

Silicon Valley seasoned Steve Newcomb is connected a ngo to standard Ethereum to 10 cardinal transactions per 2nd with zk-Rollups. History suggests you shouldn’t stake against him.

Steve Newcomb is simply a Silicon Valley seasoned with a agelong database of achievements. He built bundle for trading vigor successful the 90s, was a pioneer successful adding email to phones, and helped make the backmost extremity of the Bing hunt motor nether Peter Thiel’s mentorship. Today, helium heads up improvement for Berlin-based Matter Labs, which is gathering scaling solutions for Ethereum.

“I was precise overmuch a skeptic” erstwhile it came to cryptocurrency and blockchain, explains Newcomb, zkSync’s main merchandise officer. He adds that it took 2 years of survey earlier helium understood the taxable and the benefits to his satisfaction. 

Calculating that Ethereum had a 65% marketplace stock of the layer-1 market, Newcomb was convinced that it held the top committedness successful becoming the de facto “world computer.” But helium describes blockchain arsenic being dilatory and cumbersome contiguous arsenic the net was 25 years ago, truthful helium acceptable to enactment scaling it up to 1 time to go arsenic accelerated arsenic Web2 is now.

Layer 2s to the rescue

As a seasoned of the dot-com era, Newcomb sees the existent authorities of the blockchain situation — not conscionable Ethereum — arsenic akin to that of the net successful 1995, erstwhile the World Wide Web’s 25,000 websites could beryllium accessed by mean dial-up speeds of little than 30 kilobits per second. 

“It’s dilatory arsenic molasses. Our precise well-known ‘Ethereum net computer’ that claims to person the powerfulness to alteration the satellite runs astatine a expansive full of 15 transactions per second, and we person 4,000 morganatic projects connected Ethereum — very, precise akin to 1995.”

Just 10 years aboriginal successful 2005, websites numbered implicit 100 million, and speeds had accrued astatine slightest thirtyfold. “We had SSL, we had HTTPS by past — that small fastener icon appeared successful our browser. Amazon happened, Google happened,” helium lists. Today, successful 2022, determination are implicit 1 cardinal sites, and speeds implicit 200 megabits are communal adjacent connected mobile devices acold superior to thing Nokia engineers could person adjacent dreamed of 20 years ago.

He identifies 5 types of layer-2 solutions: authorities channels (Raiden Network, Perun), plasma (Plasma Cash, Plasma MVP), sidechains (Skale, Gnosis, Loom), Optimistic Rollups (Arbitrum, Optimism, Boba), and zero-knowledge rollups (Scroll, Matter). Newcomb has immoderate beardown opinions to share.

“If you deliberation that the extremity of furniture 2s is to standard Ethereum portion maintaining its decentralization and security, sidechains bash not execute this. They person acold little information than Ethereum does, due to the fact that their functional concatenation is not connected Ethereum’s chain,” helium states matter-of-factly. 

He feels likewise astir authorities channels and plasma, arguing that “they conscionable virtually don’t cheque the boxes.” This leaves lone Optimistic Rollups and zk-Rollups successful Newcomb’s bully graces. His passionateness comes crossed arsenic a alternatively assertive, possibly unfair, dismissal of a important information of the layer-2 scenery — but let’s prevention that treatment for a aboriginal article.

“My ngo is to marque definite that Ethereum wins. I privation it to beryllium the archetypal that gets it to spell from 15 to 1,000 oregon 10 cardinal transactions per second. I privation to beryllium successful the country erstwhile it happens.”

Serial founder

No alien to technology, Newcomb has fond memories from the 70s erstwhile astatine 6 years aged helium would solder motherboards with his father, who “worked for an bureau I can’t name.” He describes a tendency from an aboriginal property to beryllium portion of history, which propelled him successful his career. In his view, 1 should find retired what they deliberation the astir important happening happening is, and past enactment successful that happening successful immoderate mode they can. Cellphones were the archetypal of these expansive phenomena.

“When I acceptable retired connected my career, I asked myself: Is this thing that’s going to impact millions of people? Is it a large deal? Can I adhd worth successful immoderate way?”

In 2000, Newcomb founded LoudFire, a institution that aimed to physique consoles that would power astute homes, which helium describes arsenic an abject nonaccomplishment — “except that we realized however to instrumentality email from a machine and enactment it connected your Nokia phone,” which was a revolutionary operation of 2 antecedently abstracted technologies. Naturally, the steadfast was sold to Nokia successful 2002, which was the pre-iPhone juggernaut dominating the mobile telephone manufacture astatine the time.

In 2008, helium founded Powerset, a earthy connection hunt motor that was fundamentally sold to go a cardinal constituent of Microsoft’s Bing. He recalls pitching the task to capitalist Thiel by having him benignant a hunt and past asking him to prime whether Google’s results oregon those from Newcomb’s solution were better. “He chose america 70% implicit Google,” Newcomb recalls, aft which helium promptly had $800,000 successful the slope and a caller mentor. 

“Two of my inferior engineers divided disconnected to make a tiny institution called GitHub,” helium remarks.

Jingles and resumes

Newcomb describes himself arsenic having been thing of a troublemaker increasing up, applying to Salisbury University successful Maryland connected the ground that it was adjacent to a formation wherever helium could walk his days “mostly ignoring school” portion majoring successful accounting.

In the 1980s, helium wrote an algorithm to automatically make the scripts for utilized car dealerships’ TV and vigor commercials with “cheesy euphony and immoderate cheesy income guy,” charging thousands a pop. His 2nd concern portion successful assemblage was efficaciously a pre-internet mentation of LinkedIn, charging students to administer their resumes to different universities crossed the portion via a strategy of interconnected printers.

Upon graduating, Newcomb joined the vigor institution Statoil successful 1993, reasoning that it seemed similar an important manufacture to get into, arsenic the U.S. authorities had conscionable deregulated the vigor markets. At conscionable 21, helium says helium was trading $600 cardinal worthy of vigor deals per year, and helium learned to codification successful Object Pascal connected the broadside successful bid to marque his occupation easier by automation and easier control. 

The impenetrable door

With his past arsenic witness, Newcomb does not deliberation small. For him, the extremity crippled of Ethereum is information truthful cleanable that nary quantum machine tin interruption it and decentralization truthful bully that nary nation-state tin halt it — successful different words, a “private net machine that cannot beryllium hacked by immoderate machine oregon stopped by immoderate nation-state.”

“I privation radical to recognize that this is much important than technology; this is perchance arsenic important arsenic what comes aft capitalism and democracy,” helium says. He elaborates that erstwhile a caller exertion comes along, it usually replaces an incumbent, arsenic erstwhile iPhone replaced Nokia.

“What is the incumbent that blockchain replaces? If you deliberation astir it, it’s government.” 

If that’s true, determination is simply a hopeless request for adults successful the room, and Newcomb quips that helium is yet aged capable to beryllium considered one. “Imagine we built a doorway that tin ne'er beryllium knocked down. What would radical bash successful their homes?” helium asks, describing the encryption of Ethereum arsenic an impenetrable doorway down which radical tin commercialized and interact freely successful specified a mode that nary government, instauration oregon authorization tin scope them — a blockchain that runs connected its ain and is astir escaped to use.

“If you person a backstage blockchain and radical determine to bash concern connected it, past governments nary longer person a mode to taxation radical and governments are gone.” Well, maybe. History is being made 1 mode oregon another, and Newcomb is doing his champion to beryllium portion of it.

Ranking rollups

So, what are these rollups to statesman with, and wherefore are they better, according to Newcomb?

According to Ledger Academy:

“Rollups ‘roll up’ oregon compile a clump of transactions and crook them into 1 azygous information and taxable it to the Ethereum mainnet. They instrumentality the transactions retired of the mainnet and process them off-chain, person them into 1 azygous portion of data, and taxable them backmost to the Ethereum mainnet. This is wherefore rollups are besides called ‘off-chain scaling solutions.’”

There are 2 superior types: Optimistic Rollups and zk-Rollups.

According to Newcomb, Optimistic Rollups, arsenic utilized by Optimism and Arbitrum, yet beryllium connected a blase crippled theory, which efficaciously allows everyone to usage the blockchain. “And then, aft the fact, they cheque to marque definite that determination is nary fraud.” 

With this system, “you could beryllium possibly 99.999% definite there’s nary fraud, but you can’t beryllium 100%. It’s the precise champion crippled mentation we have, and it does standard Ethereum by a origin of seven, possibly up to 10.” Though helium concedes that it passes arsenic a scaling solution, Newcomb expresses concerns astir colony times astatine accrued levels of scaling, describing the process arsenic progressively “hairier” and saying that helium “couldn’t recognize however it scales beyond the archetypal 10x.”

Zk-Rollups, connected the different hand, “check for fraud utilizing mathematics — thing called a ZK impervious that isn’t 99.999% accurate. It does not usage crippled theory. It is virtually mathematically perfect.” There are competing zk-Rollup furniture 2s from ConsenSys, StarkNet and Polygon.

Clearly, they are Newcomb’s preferred solution, 1 that helium says was antecedently thought to beryllium excessively costly and 10 years distant from effectual implementation — but “we’ve solved those things overmuch faster than anyone predicted.”

“Zk-Rollups, for me, represented some standard and information combined astatine unlimited scale. We theoretically could get up to millions of transactions per second, making this a existent net computer, and we could bash truthful portion perfectly maintaining security.”

Zk-Rollups are not a singular task but a method solution being worked connected by assorted abstracted teams. Of these, Newcomb lists his apical 3 (working connected EVM-compatible solutions): Matter, Scroll and Polygon. He considers Matter, which helium works for, to beryllium 9 to 12 months up of Scroll and Polygon, with different solutions being astir 1 to 2 years down — a presumption helium has arrived astatine via a five-point database of “magic ingredients” helium believes are needed for a ZK solution to beryllium adopted.

Five points

Firstly, an L2 solution should beryllium “general purpose,” meaning that immoderate DApp oregon astute declaration tin beryllium built to interact with it, arsenic opposed to accommodating lone peculiar usage cases specified arsenic NFTs. 

Secondly, the solution should beryllium EVM-compatible, meaning that similar with BNB Chain, Polygon, Solana and Avalanche, Ethereum projects tin beryllium easy ported over. Bitcoin, Monero, Litecoin, Cardano and XRP Ledger are wholly antithetic and are examples of non-EVM compatible chains.

Thirdly, the solution should enactment Solidity, the programming connection utilized to make astute contracts connected Ethereum. “Supporting JavaScript for the web equals supporting Solidity for crypto,” Newcomb reasons.

Fourthly, a ZK-proof solution needs to beryllium open-source, “or the assemblage of crypto volition go riled up against you, arsenic it would not acceptable the ethos.”

Fully hold with this explanation of zkEVM. It's precisely what describes @zksync v2 — the zkEVM which is unrecorded connected testnet for >6 months and coming to mainnet successful <100 days.

Cheers to Polygon for giving up the mendacious EVM-equivalence claims aft conscionable 2 days! https://t.co/qQBiw2YzrZ

Lastly, Newcomb emphasizes that determination indispensable beryllium a program for tokenization that benefits the ecosystem: “Two-thirds of your tokens should beryllium dedicated to the payment of the ecosystem, not to the payment of the shareholders of the archetypal institution gathering the layer-2 solution.”

“The existent champion lawsuit is that ZK becomes a standard. That’s wherefore we open-sourced it, truthful that it tin go a nationalist good. Our anticipation successful the aboriginal is that determination are nary different protocols — it is conscionable the protocol.”

Whatever layer-2 solution(s) extremity up taking halfway signifier successful the coming years, what Newcomb looks guardant to astir is the nationalist quality of advancement that is inherent to blockchain arsenic opposed to erstwhile eras of technological development. “Engineers utilized to spot things privately and speech astir them after. We get to spot advancement unrecorded on-chain.”
