In October 2024, Ethereum’s founder Vitalik Buterin released a series of articles on the future development of the Ethereum protocol, which drew significant attention from the global blockchain community. In these articles, Vitalik elaborated on the latest progress of Ethereum’s “Surge” phase and the critical role Layer 2 solutions will play in the protocol’s future. These articles not only outlined Ethereum’s technical roadmap but also shed light on the direction Layer 2 scaling solutions are heading, signaling a significant growth opportunity for decentralized applications (dApps) and the DeFi ecosystem in the coming years.

Ethereum’s “Surge” Roadmap: Tackling the Scalability Challenge

Since its launch in 2015, Ethereum has established itself as the foundation of the blockchain industry with its smart contract platform. However, the rapid increase in network usage has brought scalability challenges to the forefront. Issues like network congestion and high transaction fees have long plagued users and developers. To address these challenges, Vitalik proposed five key phases in Ethereum’s future development: Merge, Surge, Scourge, Purge, and Splurge. The “Surge” phase, in particular, focuses on enhancing Ethereum’s scalability.

The core objective of the “Surge” roadmap is to significantly increase Ethereum’s transaction throughput through the introduction of sharding technology. Sharding is a technique that divides the blockchain into smaller parts (called shards), enabling transactions to be processed in parallel. This innovation is expected to dramatically reduce network congestion, lower transaction fees, and lay the technical foundation for Ethereum’s broader scalability.

Layer 2 Scaling Solutions: The Backbone of Ethereum’s Future

Although sharding will play an essential role in the long term, Vitalik highlighted in his articles that Layer 2 scaling solutions will be the main path to Ethereum’s scalability in the near future. Layer 2 solutions are technologies built on top of Ethereum’s main network (Layer 1) that enable scalability by moving a large volume of transactions off-chain, while maintaining the security and decentralization features of Ethereum.

Currently, leading Layer 2 solutions include Rollups, state channels, and sidechains. Among these, Rollups have gained the most traction as a core Layer 2 technology. There are two main types of Rollups: Optimistic Rollups and ZK-Rollups. Optimistic Rollups assume that transactions are valid by default to reduce computation, while ZK-Rollups leverage zero-knowledge proof technology to ensure transaction validity. Both offer distinct advantages — Optimistic Rollups are simpler and more user-friendly, while ZK-Rollups boast higher efficiency and enhanced privacy protection.

In his articles, Vitalik expressed great optimism about the future of Layer 2 solutions, noting that the further development of these technologies will propel Ethereum to new heights. Rollups and other Layer 2 technologies not only promise to dramatically improve Ethereum’s transaction capacity, but they also enable a diverse array of applications, including decentralized finance (DeFi), NFT trading, and decentralized social platforms.

Challenges and Opportunities for Layer 2

While Layer 2 technologies offer enormous potential, they also face several challenges in their implementation. One significant challenge is the complexity of the technology. Although Rollups can theoretically improve performance significantly, a variety of development, testing, and deployment hurdles need to be overcome to achieve large-scale adoption. Vitalik also pointed out that interoperability between different Layer 2 solutions is a crucial issue. Ensuring liquidity, compatibility, and security across various Layer 2 networks will be vital to the success of these solutions.

Another key factor is the user experience. While Layer 2 solutions can substantially lower transaction fees and improve speed, they may still seem complex to the average user. At present, users must navigate multiple steps and tools to move funds between different Layer 2 networks. Simplifying this process and enhancing user-friendliness will be critical for Layer 2’s widespread adoption.

Despite these challenges, the application scenarios for Layer 2 solutions are rapidly expanding as the technology matures. In the DeFi space, Layer 2 is already lowering operational costs for users and enabling the development of more complex financial products. In the NFT market, Layer 2 provides the infrastructure for mass minting and trading of NFTs, addressing the high transaction fees on Ethereum’s mainnet. Looking ahead, decentralized social platforms and games will also benefit from Layer 2, offering developers a broader range of opportunities for innovation.

The Future of Layer 2: Aiming for One Million TPS

In Vitalik’s vision, the future of Ethereum lies in the combination of Layer 2 and sharding technologies, which will enable the network to process millions of transactions per second (TPS). This will not only solve current scalability issues but also transform Ethereum into a truly global distributed computing platform. Vitalik predicts that as Rollup technologies become more widely adopted, Ethereum’s mainnet will increasingly serve as a settlement layer for Layer 2 solutions, ensuring the finality and security of transactions.

He emphasized the critical role of Rollup technology and outlined the roadmap for its optimization over the coming years. Rollups will compress transaction data to a minimum, while sharding will further enhance the overall network’s throughput. Vitalik also discussed the importance of cross-chain interoperability in the future, stating that seamless interaction between different Layer 2 networks will be the key to achieving global blockchain applications.

Conclusion: A Bright Future for Ethereum

Vitalik Buterin’s “Surge” roadmap paints an optimistic picture of Ethereum’s future. With the combination of Layer 2 and sharding technologies, Ethereum is set to evolve from a decentralized application platform into the foundational infrastructure capable of supporting global finance, social interaction, commerce, and more.

In the next few years, Layer 2 solutions will be the driving force behind Ethereum’s scalability, enabling the network to leap from handling thousands of TPS to millions. While there are technical and user experience challenges to overcome, the continued maturation of these technologies will pave the way for their resolution. Ethereum will steadily move toward its vision of becoming the global decentralized computing platform, providing a robust foundation for decentralized applications and innovation worldwide.

All of this positions Ethereum as a key player in the future of blockchain, ensuring it remains at the forefront of industry development and growth.
