The second annual Based Rollup Summit hosted by Taiko—Ethereum's first based rollup scaling solution—brought together global developers during EthCC 2025 in Cannes, France. This gathering of Ethereum Foundation members, Celo, SSV Network, and Boundless ecosystem leaders explored groundbreaking advancements in based rollup technology, preconfirmations, and Ethereum's evolving infrastructure.
Here are the 10 pivotal insights that emerged:
1. Preconfirmations Are Everywhere—Even in Your Coffee Run
Taiko COO Joaquin Mendes demystified preconfirmations by illustrating their omnipresence:
"Preconfirmations aren't exotic—they're mechanisms we use daily, like when purchasing coffee."
He detailed how Taiko's implementation delivers faster, smoother transactions while preserving Ethereum's security.
2. ZK's Winning Strategy: Solve User Needs, Not Technical Benchmarks
Boundless CEO Shiv Sankar reframed the zero-knowledge narrative:
"Stop competing on tech specs. The real victory lies in addressing user pain points better than Web2 giants like Amazon."

3. URC Integration Simplifies Validator Onboarding
SSV Network's Alon Muroch demonstrated their Universal Registry Contract (URC) integration:
"Validators can now serve based rollups with one-click registration—whether managing 10 nodes or 10,000."
4. Why Ethereum Can't Just Shorten Block Times
Taiko CEO Daniel Wang explained the decentralization tradeoff:
"Sub-second consensus would jeopardize Ethereum's 1M+ validators. Preconfirmations preserve accessibility without sacrificing security."
5. Measuring Based Preconfirmation Success
Key metrics identified by panelists:
- Operational based rollups
- 20%+ validator participation rate
- Tangible UX improvements like reduced fees
6. Enterprise Adoption Requires Privacy-Centric Design
Ethereum Foundation's Tomasz Stanczak stressed:
"Mass adoption flows through Web2 platforms. Our infrastructure must deliver enterprise-grade privacy and compliance."
7. Ethereum Needs Stronger Storytelling
Celo's Marek Olszewskii challenged the ecosystem:
"Are we attracting the right audience? Institutional investors need compelling ROI narratives beyond 'smart contract platform.'"
8. Horizontal Scaling: Ethereum's Only Path Forward
Researcher Justin Drake was unequivocal:
"Vertical scaling is exhausted. Shared sequencers and cheaper SNARK verification will enable continuous rollup settlement."

9. Booster Rollups: A Novel Scaling Paradigm
Taiko CTO Brecht Devos introduced game-changing architecture:
"Booster rollups allow direct L1 contract calls from L2, maintaining composability while scaling automatically."
10. True Scalability Means Internet-Level Usability
Closing panelists including Avail's Kyle Rojas agreed:
"Real scalability isn't just TPS—it's global accessibility that preserves decentralization and censorship resistance."
Interactive Innovations Beyond the Keynotes
Attendees experienced Taiko's technology firsthand through on-chain gaming demonstrations, blending technical depth with engaging applications.
FAQ Section
Q: How do preconfirmations differ from traditional blockchain confirmations?
A: Preconfirmations provide near-instant transaction guarantees from rollups before final L1 settlement, similar to credit card authorizations.
Q: What makes based rollups unique compared to optimistic/ZK rollups?
A: They leverage Ethereum's full security while enabling faster preconfirmations—combining the best of L1 and L2.
Q: When will Booster Rollups be production-ready?
A: Taiko's testnet already demonstrates the concept, with mainnet deployment expected by late 2025 after rigorous audits.
