What significant transition has the Celo blockchain recently completed? How does the Celo blockchain plan to enhance transaction efficiency and cost by utilizing a layer-2 network? What tools or frameworks are being adopted by Celo to facilitate this migration? How might Celo’s transition serve as a template for other Ethereum layer-1 blockchains? What are some of the challenges and considerations other blockchains may face when contemplating a move to layer-2 technology?
The Celo blockchain’s long-awaited plan of becoming an Ethereum layer-2 chain has been completed, ending an almost two-year process, the main organizations behind the network said Wednesday. The transition ends a long journey beginning back in July 2023 for the layer-1 blockchain that included a community vote in July 2024 and a fierce competition, won by Optimism, among layer-2 networks out to convince the Celo ecosystem to build with their technology. The improved network — like other layer 2s — offers faster and cheaper transactions on top of Ethereum’s mainnet. The blockchain is powered by Optimism’s OP Stack, a customizable framework that lets developers build layer-2 networks based off of Optimism’s technology.
“You know, whenever people ask us, we always recommend the OP stack, because the team there has been so helpful and so supportive,” said Marek Olszewski, the CEO at cLabs, the main developer firm supporting the Celo blockchain.
According to Rene Reisberg, the CEO of the Celo Foundation, the migration is the first of its kind in the Ethereum ecosystem and will probably be used as a blueprint for other EVM-compatible blockchains that are looking to become a layer-2 network. “This path of not just spinning up a new chain, but actually maintaining that history, and having everyone be on the new chain, while it’s a lot more work, is great from a Celo perspective. It’s becoming this kind of great case study for Ethereum,” Rene Reinsberg, the president at the Celo Foundation, said in an interview.
“Even just based on outreach I’ve been getting from other L1 founders that are like, ‘hey, so what does it actually feel like on the inside of going through this transition, and how much work is it, and how you’re thinking about it?’ And so it definitely feels like there’s increased interest now,” Reinsberg added.
Despite Ethereum’s leaders experiencing backlash from the community because of the clunky experience of operating between the plethora of layer-2 blockchains, the lagging price of ether (ETH) relative to other cryptocurrencies and the blockchain losing mindshare and new talent to competitors like Solana, Reinsberg said other layer 1s similar to Celo are watching the transition and also considering moving into the layer-2 ecosystem. “As some of these short-term storms come down and sentiment starts to shift, I think you’ll start seeing a series of layer 1s that will likely be more public about that,” Reisberg said. “But we’re definitely already seeing these early conversations happening.”
According to the team, Celo end users won’t notice much of a difference in their setups and will still be able to access key features like SocialConnect, a protocol that connects users’ phone numbers or X handles to their Celo wallet addresses to make payments. Nevertheless, there are protocol-level changes. “Validator responsibilities have evolved from operating the consensus protocol to temporarily running community RPC nodes, with validator rewards now distributed via smart contract execution rather than at epoch blocks,” the team said in a press release. “Additionally, transaction sequencing — previously determined by validators running the consensus protocol — will initially be handled by a centralized sequencer, with a roadmap in place for transitioning to decentralized sequencing in the future.”

Celo Migration to Layer-2 Network: A New Era for the Blockchain
In the dynamic landscape of blockchain technology, adaptability and scalability have become quintessential for platforms aiming to serve a growing user base and an expanding ecosystem of decentralized applications (dApps). With this in mind, Celo, a prominent player in the blockchain space focusing on mobile-first financial solutions, has successfully completed its migration to a Layer-2 network. This pivotal transition marks the beginning of a new era for Celo, promising enhanced scalability, improved transaction speeds, and lower costs, all while maintaining the platform’s core ethos of financial inclusion.
Understanding Celo’s Vision
At its core, Celo aims to provide financial services to unbanked and underbanked populations across the globe through the power of blockchain technology. By leveraging smartphones, Celo seeks to make cryptocurrency and blockchain accessible to anyone with a mobile device, creating a more inclusive financial ecosystem. Since its inception, Celo has emphasized its commitment to social impact, and the migration to a Layer-2 network is a natural step in enhancing its capacity to realize this mission.
The Need for Layer-2 Solutions
Layer-2 solutions are designed to address the limitations of Layer-1 networks, particularly concerning scalability and transaction efficiency. Celo’s original blockchain, which primarily utilized proof-of-stake (PoS) consensus, faced challenges in terms of high gas fees and slower transaction speeds during periods of high network usage. By migrating to a Layer-2 network, Celo is set to alleviate these pain points, allowing for thousands of transactions to be processed per second while significantly reducing costs.
Moreover, Layer-2 technologies, such as Rollups and state channels, enable the execution of smart contracts and transactions off-chain while still benefiting from the security and decentralization of the underlying Layer-1 blockchain. This hybrid approach not only enhances transaction throughput but also increases user engagement by providing a smoother experience for dApp developers and end-users.
Benefits of the Migration
Enhanced Scalability: With the migration to a Layer-2 network, Celo can handle a significantly larger volume of transactions. This scalability is essential for accommodating the growth of Celo’s ecosystem, which includes various dApps focused on finance, remittances, and other valuable services.
Reduced Costs: One of the primary barriers to widespread blockchain adoption has been transaction costs. After migrating, users will experience much lower fees, making it economically viable for everyday transactions, especially in lower-income regions. This affordability is key to Celo’s mission of facilitating access to financial tools for marginalized communities.
Faster Transaction Speeds: Users can now expect faster confirmations for their transactions, enhancing the overall user experience. This improvement is critical for the types of applications that Celo supports, such as payments and remittances, where speed can significantly affect user satisfaction.
Improved Developer Experience: The migration is a boon for developers within the Celo ecosystem as they can now create more sophisticated applications without worrying about the constraints of the original network. The transition to a Layer-2 solution allows for greater flexibility and innovation, which can lead to the development of new financial products and services.
- Environmental Impact: Celo has always been committed to sustainability. By moving to a Layer-2 network, the platform can potentially reduce its carbon footprint by decreasing the energy consumption associated with transactions. This aligns with the broader trend within the blockchain community to develop eco-friendly solutions.
Community and Partnerships
The successful migration to a Layer-2 network is a significant milestone, and it wouldn’t have been possible without the unwavering support of the Celo community and its partners. The Celo Foundation has played a vital role in communicating the benefits of this transition, working closely with developers and stakeholders to ensure a smooth migration. The community-driven approach fosters collaboration, making it easier to build and launch exciting new projects on the platform.
Looking Ahead
As the dust settles from this monumental transition, Celo is poised to attract a new wave of users and developers eager to explore the enhanced capabilities of the Layer-2 network. The focus on financial inclusion remains at the forefront of its agenda, and with the improved infrastructure, Celo is better equipped to create innovative solutions that can address real-world financial challenges.
The vast potential of dApps on Celo’s Layer-2 network has implications not just for the platform itself but for the entire blockchain ecosystem. As more projects embrace Layer-2 solutions, we may see a broader shift in how decentralized applications are built and utilized.
