Foreword

Bitcoin has Saylor, Ethereum has Joe Lubin.

The co-founder of Ethereum has just convinced a casino marketing company to invest $425 million in programmable currency.

His recent moves include becoming the chairman of SharpLink Gaming and negotiating with sovereign wealth funds to build financial infrastructure on Ethereum. The U.S. Securities and Exchange Commission has just dropped its lawsuit against his company ConsenSys, clearing regulatory hurdles for larger plans.

Lubin's cryptocurrency journey began at the Princeton Robotics Lab, Goldman Sachs trading floor, and a Jamaican music studio. His approach is methodical: first build the infrastructure, then drive application implementation.

Goldman's exit

Joe Lubin's cryptocurrency story began with the financial disaster he witnessed, rather than ideological beliefs.

September 11, 2001: Lubin, as the Vice President of Technology in Goldman Sachs' Private Wealth Management division, witnessed the attacks on the World Trade Center. Seven years later, he observed the global financial crisis from inside Wall Street.

His reaction was unusual. Lubin did not double down on traditional finance, but went to Jamaica to make music.

This is not a midlife crisis. The financial system has exposed its vulnerabilities twice in the past decade, and Lubin was present both times.

His journey to Goldman Sachs followed a predictable pattern. Pursue a degree in Electrical Engineering and Computer Science at Princeton University. For three years, he managed the Robotics & Expert Systems Laboratory, focusing on machine vision and autonomous vehicles. For a while, he worked at Vision Applications, where he was responsible for the development of autonomous mobile robots. After that, he entered the financial field through software consulting.

By the late 1990s, Lubin occupied the coveted intersection of ambitious tech experts' dreams—the combination of technology and vast capital. His Princeton roommate, Michael Novogratz, made similar moves in traditional finance.

Then, the high-rise buildings collapsed, the market crashed, and Lubin believed that predictable patterns were not worth it.

After being disappointed with traditional finance, Lubin moved to Jamaica with his girlfriend to become a music producer.

However, the following story reads less like a retreat and more like a field investigation.

The Discovery of Bitcoin

In 2009, Lubin stumbled upon the Bitcoin white paper while developing music software in the dancehall music scene in Jamaica.

He later recalled, "When I first encountered this technology, I experienced the 'Bitcoin moment' that many of us have gone through: it has the potential to change everything."

Lubin's Bitcoin moment differs from the typical cryptocurrency transformation story. His excitement lies in providing engineering solutions to systemic problems rather than liberal ideals or financial speculation.

The 2008 financial crisis demonstrated how centralized financial institutions can amplify risk throughout the entire economy. Bitcoin offers an alternative: a currency system that does not require intermediaries, which have just proven themselves to be unreliable.

For the next four years, Lubin continued to accumulate Bitcoin, while most people in the financial industry looked down on it at the time. He was not building a community, nor was he preaching; he was learning.

By January 2014, everything had changed.

Encounter with Ethereum

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

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

Vitalik envisioned a programmable blockchain that could do more than just value transfer. Lubin, with his background in robotics and autonomous systems, grasped its significance.

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

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

Lubin and others referred to it as the "Red Wedding," citing the betrayal scene from "Game of Thrones." For Lubin, this is not a setback, but an opportunity.

The early Ethereum core team members rented a house during the 2014 Bitcoin Conference in Miami.

The Ethereum Foundation will focus on protocol development. Others are needed to build the commercial infrastructure so that Ethereum can be used by enterprises and institutions.

Build infrastructure stack

ConsenSys was founded in October 2014, launching simultaneously with the Ethereum mainnet. Lubin's approach is systematic: to build all the infrastructure necessary for Ethereum to serve as the foundation of a financial system.

ConsenSys has not bet on a single application, but has incubated projects that cover the entire Ethereum stack:

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

User Interface: MetaMask has become the primary gateway for millions to access Ethereum applications.

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

Enterprise Solutions: Kaleido provides blockchain as a service for enterprises to meet internal build needs.

Lubin described the early stage as a "chaotic incubator," giving rise to more than 50 companies. Critics argue that it lacks focus, while Lubin refers to it as ecosystem building.

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

Progressive Decentralization Theory

Lubin's philosophy framework for building decentralized systems using centralized entities is called "progressive decentralization."

This concept addresses a practical issue: how to initiate a decentralized network when decentralized coordination is inherently difficult?

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

This strategy has achieved varying degrees of success in the ConsenSys projects. The Truffle Suite has become an open-source project, developed by the community. ConsenSys has spun off dozens of projects into independent entities, including Gnosis, reducing its direct control over its ecosystem.

But the transformation is not yet complete. MetaMask is still mainly controlled by ConsenSys, and while Infura has discussed plans for decentralized node distribution, there is no specific timeline.

"It's not inherently wrong for an entity with a fixed organizational structure to attempt to build an entity with a different organizational structure," he argued.

This philosophy allows ConsenSys to build Ethereum infrastructure without getting caught up in governance disputes or community politics. It also positions Lubin as a coordinator of the Ethereum business ecosystem while maintaining a distance from protocol governance.

Regulatory Victory

In February 2025, the U.S. Securities and Exchange Commission (SEC) agreed to dismiss the lawsuit against ConsenSys. The case accused ConsenSys of earning over $250 million in fees through MetaMask's staking and swapping services, in violation of securities laws.

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

The SEC has withdrawn the case under the "new direction" guided by the Trump administration, with no fines or additional conditions. Lubin stated, "Now we can focus 100% on building. 2025 will be the best year for Ethereum and ConsenSys."

SharpLink trading

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

The comparison with Michael Saylor comes up immediately.

Similar to Saylor's MicroStrategy, SharpLink makes large bets on cryptocurrencies using a corporate treasury strategy. Like Saylor, Lubin positions himself as a public figure for institutional adoption.

SharpLink's stock price soared over 400% after the announcement, with a cumulative increase of over 900% in the past month. The list of participants includes well-known crypto venture capital firms: ParaFi Capital, Electric Capital, Pantera Capital, Arrington Capital, Galaxy Digital, and Republic Digital.

Lubin has applied for an additional $1 billion in funding for SharpLink, of which "almost all" will be used to purchase ETH. If successful, this will create one of the largest corporate cryptocurrency vaults.

This model represents active practicality rather than passive speculation.

Sovereign Fund Declaration

SharpLink trading may just be the prelude to a larger movement.

In a recent podcast, Lubin stated that ConsenSys is negotiating with the sovereign wealth fund and major banks of "a very large country" to build infrastructure within the Ethereum ecosystem.

He declined to disclose the specific country. According to reports, the focus of these discussions is to build institutional infrastructure for the Ethereum ecosystem, including a layer protocol and customized layer two solutions.

If true, this will validate Lubin's decade-long bet on Ethereum's infrastructure. It will also distinguish Ethereum from other cryptocurrencies: as the foundational layer of national financial systems.

This opportunity coincides with the transition of central bank digital currencies (CBDC) from the experimental phase to the implementation phase. Governments need programmable currency infrastructure, and Ethereum has the most mature developer ecosystem and institutional tools.

Lubin believes this is a logical progression: "Ethereum has a unique advantage in anchoring the next phase of the global financial system."

Our viewpoint

61-year-old Lubin oversees a crypto empire built around making Ethereum truly usable. ConsenSys's most important creation is MetaMask—a browser wallet that has become the gateway for millions to access DeFi.

Without MetaMask, the Ethereum ecosystem may still be limited to the developer domain. The company has also incubated dozens of other projects, from Infura's critical node infrastructure to Truffle's development tools.

ConsenSys has not hired traditional tech workers but has assembled a unique team: entrepreneurs with an engineering mindset, protocol architects who understand business, and business experts who can translate blockchain concepts for Fortune 500 boardrooms.

The SEC's victory has eliminated regulatory uncertainty for ConsenSys's core products. SharpLink treasury transactions provide a public market tool for institutional adoption of Ethereum. If discussions around sovereign funds materialize, it could position Ethereum as the infrastructure for national financial systems.

Lubin's vision is not limited to financial applications but aims to completely transform the architecture of the internet—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 tech experts are flocking to build a decentralized web, Web 3.0, in the ecosystem. Once you see the profound impact of blockchain, you can't ignore it. Each new wave of hype will bring more and bigger builders and user communities. For these people, there is no turning back."

His recent actions indicate that this vision is shifting from theory to practice.
