Mihailo Bjelic Exits Polygon: Impact on Layer 2 Network’s Future

In a significant development for the cryptocurrency ecosystem, Mihailo Bjelic, one of the four co-founders of Polygon, has announced his departure from the Layer 2 scaling solution. This exit marks a pivotal moment in Polygon’s journey, as the network continues to evolve in the rapidly changing blockchain landscape.

Bjelic made the announcement via X (formerly Twitter), stating, “After much thought and reflection, I’ve decided to step down from the board of the Polygon Foundation, and wind down my day-to-day involvement with Polygon Labs.” This decision leaves co-founder Sandeep Nailwal as the last remaining member of the original founding team.

The Departure of a Visionary: What It Means for Polygon

Mihailo Bjelic has been instrumental in Polygon’s growth since its inception as Matic Network. His technical expertise and strategic vision helped transform Polygon from a simple scaling solution into a comprehensive ecosystem of interconnected blockchain technologies. As one of the architectural minds behind Polygon’s evolution, Bjelic’s departure raises important questions about the network’s future direction.

The timing of this announcement comes during a period of significant transformation for Polygon, which has been aggressively expanding its suite of Layer 2 solutions while navigating the competitive landscape of Ethereum scaling technologies.

Polygon’s Evolution: From Matic to Layer 2 Powerhouse

To understand the significance of Bjelic’s exit, it’s important to trace Polygon’s journey from its origins as Matic Network to its current position as a leading Layer 2 solution.

The Founding Team and Vision

Polygon was originally founded in 2017 as Matic Network by four visionaries:

  • Jaynti Kanani: The technical architect who previously worked on Housing.com
  • Sandeep Nailwal: The business strategist with extensive blockchain experience
  • Mihailo Bjelic: The Ethereum researcher who brought technical depth to the project
  • Anurag Arjun: The product manager who helped shape the user experience

The team identified a critical problem in the early Ethereum ecosystem: scalability. As Ethereum gained popularity, transaction costs rose and confirmation times lengthened, making the network impractical for many everyday applications. Matic Network was conceived as a solution to these scaling challenges, using a technology called Plasma to process transactions off the main Ethereum chain while maintaining security.

Transformation into Polygon

In February 2021, Matic Network rebranded as Polygon, signaling a significant expansion of its mission. No longer just a scaling solution, Polygon positioned itself as a framework for building and connecting Ethereum-compatible blockchain networks. This strategic pivot allowed the project to address a broader range of use cases and compete more effectively in the rapidly evolving Layer 2 space.

Under this new vision, Polygon developed multiple scaling solutions:

  • Polygon PoS (Proof of Stake): The original Matic solution, offering fast and inexpensive transactions
  • Polygon Supernets: Customizable blockchain networks for specific applications
  • Polygon zkEVM: A zero-knowledge rollup solution that maintains Ethereum compatibility
  • Polygon Miden: A STARK-based zero-knowledge rollup
  • Polygon Nightfall: A privacy-focused solution built in collaboration with Ernst & Young

This diversification strategy, which Bjelic helped architect, enabled Polygon to offer solutions tailored to different technical requirements and use cases.

The Gradual Dissolution of Polygon’s Founding Team

Bjelic’s departure represents the continuation of a pattern that has seen the gradual exit of Polygon’s original founders. Let’s examine this trend in greater detail:

FounderRoleExit DateReason (If Public)
Jaynti KananiCEO & Co-founderJuly 2023Personal reasons and desire to explore new ventures
Anurag ArjunCo-founderSeptember 2022To pursue other projects in the blockchain space
Mihailo BjelicCo-founderMay 2025Stepping down after “much thought and reflection”
Sandeep NailwalCo-founderStill activeRemains as the last original founder

This pattern of founder departures is not uncommon in the cryptocurrency space as projects mature. Early visionaries often step aside to make way for operational leaders who specialize in scaling established organizations. However, the exodus of three out of four founders within a relatively short timeframe raises questions about Polygon’s internal dynamics and future leadership structure.

Market Reaction to Bjelic’s Departure

The immediate market reaction to Bjelic’s announcement was modest but notable. Polygon’s native token, POL (previously MATIC), experienced a 5% decline in the 24 hours following the announcement, trading at approximately $0.23. This reaction suggests that while investors are concerned about the departure, they do not view it as catastrophic for the project’s prospects.

Several factors may explain this measured response:

  1. Polygon has already established itself as a major player in the Layer 2 ecosystem, with significant adoption and partnerships
  2. The gradual departure of founders over time has given the market time to adjust to the changing leadership landscape
  3. Sandeep Nailwal, who remains with the project, is highly respected in the industry and has been a public face of Polygon
  4. The broader cryptocurrency market conditions likely overshadow individual project developments

Nailwal’s Response and Future Leadership

Sandeep Nailwal, now the sole remaining founder, publicly acknowledged Bjelic’s contributions to Polygon and wished him well in his future endeavors. This gracious response suggests an amicable departure rather than internal conflict, though the full circumstances remain private.

As the last founder standing, Nailwal faces the challenge of preserving Polygon’s founding vision while continuing to adapt to the rapidly evolving Layer 2 landscape. His leadership will be crucial in navigating several key challenges:

Technical Innovation in a Competitive Landscape

The Layer 2 ecosystem has become increasingly competitive, with solutions like Arbitrum, Optimism, and Base gaining significant traction. Polygon must continue to innovate technically to maintain its position, particularly as Ethereum itself implements improvements that affect the value proposition of scaling solutions.

Governance Evolution

With the departure of multiple founders, Polygon’s governance structure will likely continue to evolve. The balance between centralized leadership and community governance will be a critical factor in the network’s long-term sustainability.

Integration with the Broader Ethereum Ecosystem

Polygon’s success depends partly on its relationship with Ethereum. As Ethereum continues its own evolution, Polygon must maintain alignment while preserving its unique value proposition.

Potential Scenarios for Polygon’s Future

Based on the current situation, several scenarios could unfold for Polygon in the post-Bjelic era:

Scenario 1: Continued Growth Under Nailwal’s Leadership

In this most optimistic scenario, Sandeep Nailwal successfully maintains Polygon’s momentum, recruiting new technical and business leaders to fill the void left by departing founders. Polygon continues to innovate and adapt to market conditions, maintaining its position as a leading Layer 2 solution.

Scenario 2: Transition to Community Governance

With the departure of most founders, Polygon could accelerate its transition toward more decentralized governance. This would involve empowering token holders and the broader community to play a greater role in decision-making, potentially through an enhanced DAO structure.

Scenario 3: Acquisition or Merger

The departure of founders sometimes precedes significant structural changes. Polygon might become an acquisition target for larger blockchain organizations seeking to enhance their scaling capabilities, or might seek strategic mergers with complementary projects.

Scenario 4: Renewed Focus on Core Products

Polygon has developed a diverse portfolio of scaling solutions. A leadership change could prompt a strategic reassessment, potentially leading to greater focus on the most promising technologies while scaling back investments in others.

Lessons from Other Founder Departures in Crypto

To understand the potential implications of Bjelic’s exit, it’s instructive to examine how other major cryptocurrency projects have fared after founder departures:

Ethereum After Vitalik’s Reduced Role

While Vitalik Buterin remains involved with Ethereum, his direct influence has gradually decreased as the project has matured. This transition has generally been successful, with Ethereum maintaining its position as the leading smart contract platform. This suggests that well-established projects can thrive even as founders step back.

EOS After Dan Larimer

The departure of Dan Larimer from EOS in January 2021 coincided with a period of declining relevance for the project. This illustrates how founder departures can exacerbate existing challenges when a project is already struggling to maintain momentum.

Cardano’s Steady Leadership

In contrast, Cardano has maintained consistent leadership under Charles Hoskinson, demonstrating how founder stability can provide continuity during extended development cycles.

Why Founders Leave Crypto Projects

The departure of founders from established crypto projects is common enough to warrant examination of the underlying patterns. Several factors typically contribute to these exits:

  • Mission Completion: Founders often have specific visions they want to realize. Once achieved, they may seek new challenges.
  • Evolving Project Needs: As projects mature, they may require different leadership skills than those possessed by founders.
  • Governance Disagreements: Differences in opinion about the future direction of a project can lead to founder departures.
  • Personal Burnout: The intense pressure of leading high-profile crypto projects can take a toll on founders’ wellbeing.
  • New Opportunities: The rapidly evolving crypto landscape constantly generates new opportunities that may attract founders away from their original projects.

While we don’t know exactly which of these factors motivated Bjelic’s decision, his reference to “much thought and reflection” suggests a carefully considered choice rather than an impulsive departure.

What’s Next for Mihailo Bjelic?

Bjelic has not publicly announced his next venture, leaving room for speculation about his future plans. Given his extensive experience in blockchain scaling and Ethereum infrastructure, several paths seem plausible:

  1. New Blockchain Project: Bjelic might launch a new venture addressing unsolved problems in the blockchain space.
  2. Advisory Roles: His expertise would be valuable to emerging projects in the Ethereum ecosystem.
  3. Research: Bjelic could return to a more research-focused role, potentially at an academic institution or research-oriented blockchain organization.
  4. Investment: Many successful founders transition to investor roles, helping to fund the next generation of innovators.

Whichever path he chooses, Bjelic’s contributions to Polygon have secured his place as a significant figure in the development of Ethereum’s scaling ecosystem.

Key Takeaways from Bjelic’s Exit

As the dust settles on this announcement, several important conclusions emerge:

  • Founder departures, while significant, don’t necessarily spell doom for established projects like Polygon
  • The gradual exit of multiple founders suggests Polygon is transitioning to a new phase of its organizational life cycle
  • Sandeep Nailwal faces both challenges and opportunities as the last remaining founder
  • The Layer 2 market remains highly competitive, requiring continuous innovation regardless of leadership changes
  • The modest market reaction suggests investors are taking a wait-and-see approach rather than panicking

Conclusion: What This Means for Polygon Users and Investors

For current users of Polygon’s various scaling solutions, Bjelic’s departure is unlikely to cause immediate changes in functionality or performance. The network’s technical infrastructure and core teams remain in place, continuing their work on improving and expanding the platform.
