Preface

Bitcoin has Saylor, Ethereum has Joe Lubin.

The co-founder of Ethereum just convinced a casino marketing firm to invest $425 million in programmable money.

His recent moves include becoming chairman of SharpLink Gaming and negotiating with sovereign wealth funds to build financial infrastructure on Ethereum. The SEC just dropped its lawsuit against his company, ConsenSys, clearing a regulatory hurdle for bigger plans.

Lubin’s path to cryptocurrency began in a Princeton robotics lab, a Goldman Sachs trading floor, and a Jamaican music studio. His approach is methodical: build infrastructure first, then drive adoption.

Goldman Sachs’ Exit

Joe Lubin’s cryptocurrency story begins with the financial disaster he witnessed firsthand, not ideological conviction.

Sept. 11, 2001: Lubin, as vice president of technology at Goldman Sachs' private wealth management unit, witnessed the attacks on the World Trade Center. Seven years later, he observed the global financial crisis from inside Wall Street.

His response was extraordinary. Instead of doubling down on traditional finance, Lubin headed to Jamaica to make music.

This was no midlife crisis. Twice in a decade the financial system had exposed its fragility, and Lubin was there both times.

His path to Goldman Sachs followed a predictable pattern. He studied electrical engineering and computer science at Princeton University. For three years, he ran the Robotics and Expert Systems Lab, working on machine vision and self-driving cars. Then he worked at Vision Applications, developing autonomous mobile robots. Then he moved into finance through software consulting.

By the late 1990s, Lubin had occupied the coveted intersection of ambitious technologists—the marriage of technology and big money. His Princeton roommate, Michael Novogratz, was making a similar move in traditional finance.

Then, tall buildings fell, markets crashed, and Lubin decided that the predictable patterns weren’t worth it.

After becoming disillusioned with traditional finance, Lubin moved to Jamaica with his girlfriend and became a music producer.

However, the story that follows reads less like a retreat and more like a field trip.

The Discovery of Bitcoin

Lubin was developing music software for Jamaica’s dancehall music scene in 2009 when he stumbled upon Bitcoin’s white paper.

“When I was introduced to the technology, I had the ‘Bitcoin moment’ that many of us have had: it had the potential to change everything,” he later recalled.

Lubin’s Bitcoin moment is different from the typical cryptocurrency transformation story. His excitement lies in providing an engineering solution to a systemic problem rather than libertarian ideals or financial speculation.

The 2008 financial crisis demonstrated how centralized financial institutions can amplify risk across the entire economy. Bitcoin offers an alternative: a monetary system that doesn’t require intermediaries, who have just proven themselves to be unreliable.

Over the next four years, Lubin accumulated Bitcoin at a time when most of the financial world was dismissing it. He wasn’t building a community or preaching, he was learning.

Then in January 2014, everything changed.

Encounter with Ethereum

“In November 2013, Vitalik Buterin wrote the first 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 was all in,” he said.

“In November 2013, Vitalik Buterin wrote the first version of the Ethereum white paper. On January 1, 2014, I discussed the white paper with Vitalik and received a copy. That was my Ethereum moment. I was fully committed,” he said.

Vitalik envisions a programmableBlockchain, not only can value be transferred. Lubin, with his background in robotics and autonomous systems, understood the significance of this.

A few months later, Lubin positioned himself as the business architect of Ethereum. Vitalik was responsible for the technical vision, while Lubin was responsible for the practical operations of turning the white paper into a working system.

This process was full of drama. On June 7, 2014, the founding team of Ethereum gathered in Zug, Switzerland, planning to build Ethereum into a for-profit company. But internal political factors intervened. After private discussions, Vitalik announced that Charles Hoskinson and Steven Chetrit would withdraw, and Ethereum would become a non-profit foundation.

Lubin and others called it the “Red Wedding,” a reference to the betrayal scene in Game of Thrones. To Lubin, it was not a setback but an opportunity.

The Ethereum Foundation will focus on protocol development. Others will be needed to build the commercial infrastructure that makes Ethereum usable by enterprises and institutions.

Building the infrastructure stack

ConsenSys was founded in October 2014, launching at the same time as the Ethereum mainnet. Lubin’s approach is systematic: building all the infrastructure needed for Ethereum to serve as the foundation of a financial system.

Rather than betting on a single application, ConsenSys incubates projects covering the entire Ethereum stack:

• Infrastructure: Infura provides API access to Ethereum nodes, which most decentralized finance (DeFi) applications rely on to run.

• User Interface: MetaMask has become the primary entry point for millions of people to access Ethereum applications.

• Developer Tools: Truffle Suite has become the standard for Ethereum development.

• Enterprise Solutions: Kaleido providesBlockchainAs a service for internal build needs.

Lubin describes the early stages as a “chaotic incubator” that has spawned more than 50 companies. Critics say it lacks focus, but Lubin calls it ecosystem building.

This approach reflects his engineering background. In robotics, you need to build perception systems, processing systems, execution systems, and coordination protocols. Lubin applies similar systems thinking to Ethereum.

Theory of Progressive Decentralization

Lubin’s philosophical framework for building decentralized systems out of centralized entities is called “progressive decentralization.”

This concept solves a practical problem: how to launch a decentralized network when decentralized coordination is inherently difficult?

Lubin’s strategy is to start with centralization, build the infrastructure, and then gradually hand over control to the community as the technology matures.

This strategy has worked to varying degrees for ConsenSys projects. Truffle Suite became an open source project with community-driven development. ConsenSys has spun off dozens of projects into independent entities, including Gnosis, reducing its direct control over its ecosystem.

But the transition is not yet complete. MetaMask is still largely controlled by ConsenSys, and Infura has discussed plans for decentralized node distribution but without a specific timeline.

“There’s nothing wrong in itself with having an entity that’s organized in a fixed way try to build an entity that’s organized differently,” he argued.

This philosophy enables ConsenSys to build Ethereum infrastructure without getting bogged down in governance debates or community politics. It also allows Lubin to serve as a coordinator of the Ethereum business ecosystem while keeping his 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 accused ConsenSys of violating securities laws by earning more than $250 million in fees through MetaMask's staking and exchange services.

ConsenSys filed a countersuit in April 2024, arguing that treating ETH as a security would criminalize basic network usage.

The SEC dropped the case without fines or conditions, following its “new direction” under the Trump administration. “Now we can focus on building,” Lubin said. “2025 will be the best year yet for Ethereum and ConsenSys.”

SharpLink Transaction

In May 2025, SharpLink Gaming, an online casino affiliate marketing company, announced a $425 million private placement to build an Ethereum vault. Joe Lubin became chairman of the board.

Comparisons to Michael Saylor immediately emerged.

Similar to Saylor’s MicroStrategy, SharpLink uses a corporate treasury strategy to make big bets on cryptocurrencies.Similar to Saylor, Lubin is positioning himself as the public face of institutional adoption.

SharpLink's stock price soared by more than 400% after the announcement, and has risen by more than 900% in the past month. The list of participants includes well-known crypto venture capital companies: ParaFi Capital, Electric Capital, Pantera Capital, Arrington Capital, Galaxy Digital, and Republic Digital.

Lubin has applied to raise an additional $1 billion for SharpLink, “substantially all” of which will be used to buy ETH. If successful, this would create one of the largest corporate cryptocurrency vaults.

This model represents active utility rather than passive speculation.

Sovereign Fund Statement

The SharpLink deal could be just the beginning of a bigger move.

In a recent podcast, Lubin said ConsenSys is in talks with the sovereign wealth fund of “a very large country” and major banks to build infrastructure within the Ethereum ecosystem.

He declined to name specific countries. The discussions reportedly focused on building institutional infrastructure for the Ethereum ecosystem, including both layer-one protocols and customized layer-two solutions.

If true, this would validate Lubin’s decade-long bet on Ethereum infrastructure. It would also be what sets Ethereum apart from other cryptocurrencies: as the base layer of a nation’s financial system.

This timing coincides with the central bank digital currency (CBDC) moving from the experimental stage to the implementation stage. Governments need programmable currency infrastructure, and Ethereum has the most mature developer ecosystem and institutional tools.

Lubin sees this as a logical progression: “Ethereum is uniquely positioned to anchor the next phase of the global financial system.”

Our View

Lubin, 61, presides over a crypto empire built around tools that make Ethereum truly usable. ConsenSys’ most important creation is MetaMask, a browser wallet that became a gateway to DeFi for millions of people.

Without MetaMask, the Ethereum ecosystem might have remained limited to the developer realm. The company has also incubated dozens of other projects, from critical node infrastructure with Infura to developer tools with Truffle.

Rather than hiring traditional tech workers, ConsenSys assembled a unique team: entrepreneurs with an engineering mindset, protocol architects who understood business, and enterprise experts who could translate blockchain concepts for Fortune 500 boardrooms.

The SEC’s victory removes regulatory uncertainty around ConsenSys’ core product. SharpLink treasury trading provides an open market vehicle for institutional adoption of Ethereum. If sovereign fund discussions come to fruition, it could position Ethereum as infrastructure for national financial systems.

Lubin’s vision goes beyond financial applications to completely reinvent the internet architecture — a decentralized World Wide Web (Web 3.0) where users own their data, applications resist censorship, and economic value flows directly between creators and consumers.

He explained: “Entrepreneurs and technologists are flocking into the ecosystem to build the decentralized World Wide Web, Web 3.0. Once you see the profound impact of blockchain, it’s impossible to ignore. Each new wave of the hype cycle will bring more and larger groups of builders and users. For these people, there is no turning back.”

His recent actions suggest that this vision is moving from theory to practice.
