Taiko Hosts Second Based Rollup Summit In Cannes: Preconfirmations Are Key, Horizontal Scaling Is Ethereum’s Path Forward
In Brief
Taiko’s second Based Rollup Summit in Cannes brought together industry leaders to explore Ethereum scalability, preconfirmations, booster rollups, and strategies for mainstream adoption without compromising decentralization.
Based rollup scaling project Taiko has organized the second Based Rollup Summit in Cannes, held concurrently with EthCC Cannes 2025, maintaining the ongoing dialogue on the future of Ethereum scalability. The event brought together developers, industry figures, and technology experts to examine current progress in based rollup solutions, explore the role of preconfirmations, and assess the broader developments influencing Ethereum’s next phase.
Joaquin Mendes, Chief Operating Officer at Taiko, began the summit by discussing preconfirmations, highlighting their presence in routine interactions. He illustrated how these mechanisms function and their significance in enhancing the efficiency and responsiveness of the Taiko network. His remarks provided context for the role of based preconfirmations in improving the scalability of Ethereum.
Shiv Sankar, Chief Executive Officer of Boundless, spoke about the priorities within the zero-knowledge domain, focusing on practical application rather than competing technologies. He pointed out that the key challenge lies not within the Web3 space but in addressing competition from major established technology companies. Sankar underlined the importance of identifying user needs and delivering solutions that provide tangible value, noting that user spending and revenue serve as meaningful indicators of what is genuinely important to end users.
Alon Muroch, Chief Executive Officer of SSV Network, presented the Universal Registry Contract (URC) and described how SSV is simplifying validator access to based rollup infrastructure. He noted the growing significance of Layer 2 networks in transaction volume, suggesting this shift offers new potential for both validators and rollup systems. By integrating the URC directly into their client software, SSV has removed common registration hurdles, making participation more accessible across different validator sizes.
In a separate segment, Daniel Wang, Chief Executive Officer of Taiko, addressed a structural consideration regarding Ethereum’s design and the role of based preconfirmations. He explained that while Taiko aims to reduce block times from 12 seconds to below 2, achieving such speeds directly on Ethereum is not feasible without undermining decentralization. With a validator set exceeding one million participants, reaching consensus in sub-second intervals would demand either a reduction in validator numbers or the use of significantly more powerful hardware, both of which would contradict Ethereum’s foundational principles of inclusivity and decentralization.
Speakers Highlight Path To Scalable Ethereum Adoption
Speakers at the summit discussed measurable indicators of progress, emphasizing real-world adoption and sustainable economic models. A shared view emerged that a benchmark would be the deployment of a based rollup utilizing preconfirmations and Layer 1 proposers, with at least 20% of the stake actively participating. Additional goals included lowering transaction costs and enhancing overall usability.
Tomasz K. Stanczak, Co-Executive Director at the Ethereum Foundation, shared insights into the broader strategy for achieving widespread adoption. He explained that the approach does not prioritize direct user engagement, as end users are expected to interact with blockchain technology through interfaces provided by large institutions. The core objective, he noted, is to ensure that blockchain infrastructure remains central while supporting enterprises in addressing regulatory challenges.
Marek Olszewski, Chief Executive Officer of Celo, brought attention to the need for Ethereum to better position itself for institutional and mainstream adoption. He questioned whether the current user base aligns with Ethereum’s long-term goals and highlighted the importance of distinguishing Ethereum from competing platforms by reinforcing its role as a yield-generating network.
Justin Drake, a researcher at the Ethereum Foundation, emphasised the limitations of vertical scaling for Ethereum, stating that future scalability must rely on horizontal expansion. He pointed out that even increases in computational capacity would not be sufficient, reinforcing the necessity of a broader scaling approach.
Brecht Devos, Co-founder and Chief Technology Officer at Taiko, introduced the idea of booster rollups, outlining how this approach contrasts with conventional scaling methods. He explained that while most activity and smart contracts remain on Layer 1, each rollup can establish a direct connection to that base layer. This architecture enables Layer 2 networks to access Layer 1 smart contracts seamlessly, supporting scalability while preserving composability across layers.
Can Blockchain Match The Scale Of Internet Platforms Without Compromising Decentralization?
The event concluded with a broader discussion on the meaning of blockchain scalability, featuring contributions from Kyle Rojas of Avail, Gustavo from OpenZeppelin, and Harry Gao of Luban. The dialogue centered on whether blockchain infrastructure can match the scale and usability of mainstream internet platforms. Participants agreed that true scalability involves reaching global capacity without compromising essential features such as decentralization, resistance to censorship, and system integrity. Rather than simply pursuing higher transaction throughput, the focus remains on developing infrastructure that can support worldwide adoption without sacrificing core blockchain principles.
In addition to technical exploration, the summit included interactive elements, such as gaming experiences powered by Taiko’s technology, offering a practical demonstration of how blockchain can merge utility with engagement. The concepts of preconfirmations and booster rollups presented throughout the event reflect ongoing efforts to scale Ethereum in a way that upholds its foundational values while addressing the demands of global usage.
