Offchain Labs CEO Steven Goldfeder’s crypto origin story is basic geek gold. As a pupil at Princeton, he first heard about Bitcoin in 2013 throughout a go to day at Princeton.
Professor Ed Felten — the longer term inventor of rollups on Ethereum, co-founder of Arbitrum and a White Home science advisor — gave a five-minute lightning discuss the price of a authorities destroying Bitcoin.
Goldfeder’s curiosity was immediately piqued, and that night time, different college students hosted a poker sport with a half-BTC buy-in. As he says:
“That was again within the days when that was simply ten bucks. If solely I’d held onto it…”
Goldfeder doesn’t really want to fret about that missed alternative now that Arbitrum has change into a serious pressure in crypto. It was designed to repair a number of the points plaguing Ethereum, equivalent to excessive gasoline charges, sluggish transaction speeds and scalability bottlenecks. It’s at present the chief amongst Ethereum L2 scaling options.
However rollups have been criticized for relying too closely on centralized sequencer income and for an absence of interoperability and composability within the ecosystem. Ethereum Basis researchers have proposed making rollups “based mostly” and/or “native” to repair these issues.
Regardless of experiences popping out of January’s sequencing name suggesting Arbitrum would embrace these options, Goldfeder seems to have had a rethink.
Why Arbitrum gained’t change into a based mostly rollup
Based mostly rollups use Ethereum’s validators for sequencing, opening up the opportunity of interoperability and composability amongst L2s. Native rollups, in the meantime, would use Ethereum’s base layer community to interchange fraud-proof programs and make L2s as safe as Ethereum itself.
However Goldfeder now sounds much more skeptical about the advantages for Arbitrum in adopting the tech.
“Simply to make clear the phrases, you recognize, a based mostly rollup is mainly a rollup and not using a sequencer that makes use of Ethereum for sequencing. Really, in case you take a look at that preliminary Arbitrum paper that we wrote in 2018, you may name it a based mostly rollup. It doesn’t have a sequencer; that solely got here later,” he says.
As for native execution, he echoes Vitalik Buterin’s sentiment: Ethereum’s energy lies in its range.
“And one factor we experiment in is completely different execution fashions. So, Arbitrum is totally EVM but in addition has one thing referred to as Stylus, which provides you the flexibility to write down good contracts in different languages equivalent to Rust, C and C++,” he says.
“However I believe having put this method in manufacturing for 4 years, in several testnet phases, I believe the design that we’ve come on is definitely the proper one.”
“So, I don’t suppose Arbitrum will change into a based mostly rollup anytime quickly, and I don’t suppose that it ought to relating to native execution.”
Journal determined to hunt additional clarification and context from Arbitrum on its place after the interview was performed. Relating to the possibilities of his L2 turning into a based mostly rollup, Goldfeder confirmed in a press release that he believes Arbitrum’s present design is “extra environment friendly, sensible, and cost-effective” than based mostly rollup designs.
He was extra circumspect in regards to the possibilities of Arbitrum making use of the know-how that underpins native rollups however made no dedication to take action.
“I help Vitalik’s view of native rollups, which envisions a typical core that we issue out that can be helpful by many rollups, but in addition offers for rollups to increase that with extra options,” he stated. “Some rollups might select to cease on the widespread core, nevertheless it’s essential that we additionally help continued innovation and experimentation on the execution layer.”
From poker to protocols: Origins of Arbitrum
After Goldfeder’s crypto introduction at Princeton in 2013, his educational pursuits led him into cryptography and multiparty computation, finally touchdown him within the thick of blockchain safety analysis.
By 2018, he had co-founded Offchain Labs with the aforementioned Felten, reviving an previous Princeton analysis challenge. The outcome? Arbitrum — the rollup resolution whose historical past really predates Ethereum going reside.
Not like the numerous crypto tasks with names that sound like unhealthy sci-fi film titles, Arbitrum has a transparent etymology. “It comes from arbitration,” Goldfeder explains. “So, the thought is we take as a lot computation off Ethereum as doable whereas having Ethereum to be the type of referee. If one thing goes fallacious, Ethereum can, you recognize, sort things.”
This method aligns completely with Ethereum’s philosophy — decentralized, permissionless and resilient.
How Arbitrum competes in Ethereum’s layer-2 race
The layer-2 house is crowded, with heavyweights equivalent to Optimism, ZKsync and StarkNet all competing for dominance. Arbitrum has been the highest canine for a while, however Coinbase’s L2, Base, is snapping at its heels, and quicker rollups that sacrifice some decentralization for pace like MegaETH — already working at 20,000 TPS on testnet — appear more likely to siphon some customers.
Goldfeder says Arbitrum has full EVM compatibility, enabling builders to port their Ethereum good contracts to Arbitrum with zero modifications. No new languages, no arcane integrations — simply plug and play.

Gasoline charges are aggressive, too. Arbitrum slashes Ethereum’s brutal gasoline charges by batching transactions, making DeFi, NFTs and gaming apps way more accessible.
However Arbitrum’s true benefits, in response to Goldfeder, are its decentralization and safety. Some L2 options have centralized choke factors, whereas Arbitrum was the primary general-purpose rollup to attain Stage 1 decentralization.
This marks a transition the place the chain state is verified with fault proofs however retains an override mechanism requiring consensus from each operators and exterior stakeholders, lowering dependence on operators alone — a feat that Goldfeder alleges many opponents have but to succeed in.
As for Stage 2, which represents the perfect state the place the community is totally managed by good contracts, it eliminates the necessity for any human operators and achieves true permissionless validation, that means anybody can submit fraud proofs; that continues to be a bit of means off.
Arbitrum’s challenges and roadblocks
Regardless of its success, Arbitrum isn’t with out hurdles, and Goldfeder is effectively conscious that competitors is fierce, with rival L2 Optimism’s ecosystem rising, Base aggressively scaling, ZKsync providing cryptographic certainty and StarkNet’s zero-knowledge proofs additionally making waves.
Goldfeder additionally needs to make enhancements to safety.
“So, Arbitrum is like the unique layer, the earliest optimistic rollup, the primary normal objective layer 2 to launch. And the issues that we take very significantly and are paramount to us is that we all the time put safety and decentralization and (values like) censorship resistance over development.”
Arbitrum DAO actually does have management, says Goldfeder
Governance in crypto is commonly a facade — a handful of insiders pulling the strings whereas tokenholders merely play alongside. Not so with Arbitrum, says Goldfeder.
Goldfeder says the Arbitrum DAO is completely different in that many governance fashions are advisory — the inspiration has the ultimate say. However with Arbitrum, governance is self-executing. Token holders management billions in belongings, handle protocol upgrades, and even determine how charges are distributed.
“The Arbitrum DOA is instantly managed by the tokenholders onchain. And by the best way, for the charges for the community, these don’t come to me. These don’t come to some centralized basis pockets. These go on to the onchain treasury,” he says.
Which may be so, however final month, a proposal by Arbitrum DAO’s just lately appointed development administration committee sparked backlash after recommending that 7,500 ETH be deployed to Lido, Aave and Fluid, three decentralized finance protocols that aren’t native to Arbitrum.
Take the Gaming Catalyst Program (GCP), a $200-million initiative to spice up Web3 gaming. Not like conventional VC-backed funds the place earnings go to insiders, GCP’s sole LP is the Arbitrum neighborhood itself, which is voted on by the DAO. Each success instantly advantages tokenholders, reinforcing a real possession mannequin.
Past L2 scaling, Offchain Labs can also be instantly contributing to Ethereum’s core improvement. “We constructed Prysm, Ethereum’s main consensus consumer,” Goldfeder notes. “The merge, the shift to proof-of-stake, and even upcoming blob transactions — our staff is among the core builders which can be central to that dialog.”
After which there’s Arbitrum Orbit — a framework permitting builders to spin up their very own custom-made chains. With over 100 orbit chains in improvement, Arbitrum is trying to change into the AWS of Web3, providing tailored blockchain options for enterprises, DAOs and innovators.
Arbitrum’s future in Ethereum scaling
Arbitrum is bridging the hole between Ethereum’s beliefs and real-world usability. By trying to slash prices, enhance pace and decentralize governance, it’s attempting to pave the best way for a future the place Ethereum can compete with conventional monetary programs with out compromising its core ideas.
Goldfeder has the ultimate phrase: “Not like another scaling strategies, Arbitrum stays carefully built-in with Ethereum’s decentralized framework.”
That is still to be seen, however 12 years after an notorious sport of poker utilizing Bitcoin in 2013, Goldfeder and his firm might but up the ante.
