Preface
Bitcoin has Saylor; Ethereum has Joe Lubin.
The co-founder of Ethereum has just convinced a casino marketing company to invest $425 million into programmable money.
His recent moves include becoming chairman of SharpLink Gaming and negotiating with sovereign wealth funds to build financial infrastructure on Ethereum. The U.S. Securities and Exchange Commission (SEC) recently dropped its lawsuit against his company ConsenSys, clearing regulatory hurdles for larger ambitions.
Lubin’s path into cryptocurrency began in a Princeton robotics lab, a Goldman Sachs trading floor, and a Jamaican music studio. His approach is methodical: first build the infrastructure, then drive application adoption.
Exit from Goldman Sachs
Joe Lubin’s journey into crypto began not with ideology, but with firsthand observation of financial disasters.
September 11, 2001: Lubin, then Vice President of Technology at Goldman Sachs’ private wealth management division, witnessed the attack on the World Trade Center. Seven years later, he observed the global financial crisis from within Wall Street.
His response was unusual. Instead of doubling down on traditional finance, Lubin moved to Jamaica to produce music.
This wasn’t a midlife crisis. The financial system had revealed its fragility twice within a decade—and both times, Lubin was there in person.
His entry into Goldman followed a predictable trajectory. He earned a degree in Electrical Engineering and Computer Science from Princeton University. For three years, he managed a robotics and expert systems laboratory, working on machine vision and autonomous vehicles. After stints developing mobile robots at Vision Applications, he entered finance through software consulting.
By the late 1990s, Lubin occupied the coveted intersection where ambitious technologists dream of being—technology meets massive capital. His Princeton roommate, Michael Novogratz, made a similar move into traditional finance.
Then towers fell, markets crashed, and Lubin decided predictable patterns weren't worth pursuing.
Disillusioned with traditional finance, Lubin moved to Jamaica with his girlfriend to become a music producer.
But what followed reads less like retirement and more like field research.
Discovering Bitcoin
In 2009, while developing music software in Jamaica’s dancehall scene, Lubin stumbled upon the Bitcoin whitepaper.
He later recalled: “When I encountered this technology, I went through what many of us call the ‘Bitcoin moment’—the realization that it could change everything.”
Lubin’s Bitcoin moment differed from typical crypto conversion stories. His excitement stemmed not from libertarian ideals or financial speculation, but from seeing an engineering solution to systemic failures.
The 2008 financial crisis demonstrated how centralized institutions could amplify risk across the entire economy. Bitcoin offered an alternative: a monetary system without intermediaries—intermediaries that had just proven themselves untrustworthy.
Over the next four years, Lubin quietly accumulated Bitcoin while most in finance dismissed it. He wasn’t building communities or evangelizing—he was learning.
Then, in January 2014, everything changed.
Encounter with Ethereum
“In November 2013, Vitalik Buterin wrote the initial version of the Ethereum whitepaper. On January 1, 2014, I discussed the project with Vitalik and received a copy. That was my Ethereum moment. I went all in,” he said.
Vitalik envisioned a programmable blockchain capable of more than just value transfer. With his background in robotics and autonomous systems, Lubin immediately grasped its significance.
Within months, Lubin positioned himself as Ethereum’s business architect. While Vitalik focused on technical vision, Lubin took charge of turning the whitepaper into a functional system.
The process was dramatic. On June 7, 2014, the founding team gathered in Zug, Switzerland, planning to establish Ethereum as a for-profit company. Internal politics intervened. After closed-door discussions, Vitalik announced Charles Hoskinson and Steven Nerayoff were out, and Ethereum would become a non-profit foundation.
Lubin and others called it the “Red Wedding,” referencing the betrayal scene from *Game of Thrones*. For Lubin, it wasn’t a setback—it was an opportunity.

The Ethereum Foundation would focus on protocol development. Others would need to build the commercial infrastructure to make Ethereum usable for enterprises and institutions.
Building the Infrastructure Stack
ConsenSys was founded in October 2014, launching alongside the Ethereum mainnet. Lubin’s approach was systematic: build all the infrastructure required for Ethereum to serve as the foundation of a new financial system.
Rather than betting on a single application, ConsenSys incubated projects spanning the entire Ethereum stack:
-
Infrastructure: Infura provides API access to Ethereum nodes—most decentralized finance (DeFi) applications rely on it.
-
User Interface: MetaMask became the primary gateway for millions to access Ethereum applications.
-
Developer Tools: Truffle Suite became the standard for Ethereum development.
-
Enterprise Solutions: Kaleido offers blockchain-as-a-service for corporations building internal solutions.
Lubin described the early phase as a “chaotic incubator” that spawned over 50 companies. Critics saw lack of focus; Lubin called it ecosystem building.
This approach reflected his engineering roots. In robotics, you must build perception, processing, execution, and coordination systems. Lubin applied similar systemic thinking to Ethereum.
The Theory of Progressive Decentralization
Lubin’s philosophy of using centralized entities to build decentralized systems is known as “progressive decentralization.”
This framework addresses a practical challenge: How do you launch a decentralized network when decentralized coordination itself is difficult?
Lubin’s strategy: Start centralized, build infrastructure, then gradually transition control to the community as the technology matures.
This approach has seen mixed results across ConsenSys projects. Truffle Suite became an open-source, community-driven project. ConsenSys has spun off dozens of ventures—including Gnosis—reducing its direct control over the ecosystem.
But the transition remains incomplete. MetaMask is still largely controlled by ConsenSys, and while Infura has discussed plans for decentralized node distribution, no concrete timeline exists.
“There's nothing wrong with a fixed-structure organization trying to build something with a different organizational structure,” he argues.
This philosophy allowed ConsenSys to build critical Ethereum infrastructure without getting bogged down in governance debates or community politics. It also positioned Lubin as the coordinator of Ethereum’s business ecosystem while maintaining distance from protocol governance.
Regulatory Victory
In February 2025, the U.S. Securities and Exchange Commission (SEC) agreed to drop its lawsuit against ConsenSys. The case alleged that ConsenSys earned over $250 million in fees through MetaMask’s staking and swap services, violating securities laws.
ConsenSys filed a countersuit in April 2024, arguing that treating ETH as a security would criminalize basic network usage.
The SEC dropped the case under the Trump administration’s “new direction,” imposing no fines or conditions. Lubin stated: “Now we can be 100% focused on building. 2025 will be Ethereum and ConsenSys’ best year yet.”
The SharpLink Deal
In May 2025, online casino affiliate marketing firm SharpLink Gaming announced a $425 million private placement to build an Ethereum treasury. Joe Lubin became chairman of the board.
Comparisons to Michael Saylor emerged immediately.
Like Saylor’s MicroStrategy, SharpLink is employing a corporate treasury strategy to make large-scale bets on cryptocurrency. Like Saylor, Lubin is positioning himself as a public face of institutional adoption.
SharpLink’s stock surged over 400% following the announcement, rising more than 900% in the past month. Participants include major crypto venture firms: ParaFi Capital, Electric Capital, Pantera Capital, Arrington Capital, Galaxy Digital, Republic Digital.
Lubin has applied to raise an additional $1 billion for SharpLink, with “almost all” proceeds earmarked for ETH purchases. If successful, this would create one of the largest corporate crypto treasuries.
This model represents active utility rather than passive speculation.
Sovereign Fund Initiative
The SharpLink deal may be just the opening act.
In a recent podcast, Lubin revealed that ConsenSys is in talks with a sovereign wealth fund from “a very large country” and major banks to build infrastructure within the Ethereum ecosystem.
He declined to name the country. Reports suggest these discussions center on building institutional-grade infrastructure for Ethereum, including Layer 1 enhancements and customized Layer 2 solutions.
If realized, this would validate Lubin’s decade-long bet on Ethereum infrastructure. It would also differentiate Ethereum from other cryptocurrencies—positioning it as foundational infrastructure for national financial systems.
This timing aligns with central bank digital currencies (CBDCs) moving from experimentation to implementation. Governments need programmable money infrastructure, and Ethereum boasts the most mature developer ecosystem and institutional tooling.
Lubin sees this as a logical progression: “Ethereum has a unique advantage in anchoring the next phase of global finance.”
Our Take
At 61, Lubin oversees a crypto empire built around tools that make Ethereum truly usable. ConsenSys’ most important creation is MetaMask—a browser wallet that became the portal for millions to access DeFi.
Without MetaMask, the Ethereum ecosystem might have remained confined to developers. The company has also incubated dozens of other projects—from Infura’s critical node infrastructure to Truffle’s development tools.
Instead of hiring conventional tech workers, ConsenSys assembled a unique team: entrepreneurs with engineering minds, protocol architects who understand business, and enterprise experts who can translate blockchain concepts for Fortune 500 boards.
The SEC victory eliminated regulatory uncertainty around ConsenSys’ core products. The SharpLink treasury deal provides a public market vehicle for institutional Ethereum adoption. If the sovereign fund talks succeed, Ethereum could become foundational infrastructure for national financial systems.
Lubin’s vision extends beyond finance—to a complete overhaul of internet architecture: a decentralized web (Web3), where users own their data, applications resist censorship, and economic value flows directly between creators and consumers.
He explains: “Entrepreneurs and technologists are flocking to the ecosystem to build the decentralized web, Web3. Once you see the profound implications of blockchain, you can’t unsee them. Each new wave of hype brings more—and bigger—builders and user bases. For these people, there’s no going back.”
His recent actions show this vision is shifting from theory to practice.
