Vitalik Buterin, one of the founders of Ethereum, recently announced a significant change in his support strategy for Layer-2 (L2) scaling solutions. While previously many L2 networks received attention, in 2025 Buterin has committed to supporting only one L2 network. This decision could have a major impact on the development of Ethereum and the crypto ecosystem as a whole. Let's review the predictions regarding this move and its impact on the blockchain industry.
L2 Technology Consolidation
Currently, there are several L2 networks used for Ethereum scaling, such as Optimism, Arbitrum, and zkSync. However, if Buterin only supports one L2 network in 2025, this could lead to the consolidation of L2 technology. The chosen network will be the center of attention, attracting more developers, projects, and investments. The chosen L2 solution will likely become the industry standard for Ethereum scaling, while other networks may experience declining interest or even exit the competition.
Rollup Dominance or zk-Rollups
Vitalik Buterin has often emphasized the potential of zk-Rollups (zero-knowledge rollups) as the best technology for scaling Ethereum. zk-Rollups allow for much faster and cheaper transaction processing without sacrificing security. Assuming that zk-Rollups will be Buterin’s chosen L2 network, we can anticipate that this technology will dominate the Layer-2 market. It will also revolutionize the way Ethereum operates, with the ability to process more transactions without putting pressure on Ethereum’s Layer-1 (mainnet).
Accelerating Mass Adoption
With a fully supported L2 network, Ethereum’s mass adoption could happen faster. Lower transaction fees and faster processing times will make Ethereum even more attractive not only to developers but also to mainstream users and large institutions. Sectors like decentralized finance (DeFi), NFTs, and other blockchain-based applications could directly benefit from this change. Lower fees and increased efficiency could make Ethereum more competitive in the global blockchain market.
Interoperability Improvements
Buterin’s support for a single L2 network could lead to increased interoperability between Ethereum and other blockchains. Better interoperability would make it easier to transfer assets and data between networks, paving the way for a more integrated blockchain ecosystem. Ultimately, this could have a major impact on the pace of global adoption of blockchain technology, expanding the use of digital assets and smart contracts across industries.
Pressure Reduction on Mainnet
With the majority of transaction activity and dApps happening on Layer-2, the pressure on the Ethereum mainnet will be significantly reduced. The mainnet can focus more on its role as a security and decentralization layer, while the majority of day-to-day transactions are processed on the Layer-2 network. This will make Ethereum more efficient, reduce network congestion, and strengthen its technological foundation.
Impact on the Crypto Ecosystem
Vitalik Buterin’s decision to support only one L2 network by 2025 will have a major impact on the crypto ecosystem. First, the chosen L2 network will become the dominant force, attracting more users and developers to the Ethereum ecosystem. Second, competing blockchains such as Solana, Avalanche, or Binance Smart Chain will face fiercer competition. If Ethereum can solve its scalability issues, it could attract more users from other blockchains.
Third, the price of ETH is likely to be positively affected. If the Ethereum network becomes more efficient and widely used, the value of ETH assets could increase due to increased demand and network activity. Fourth, the potential centralization in one L2 solution could be a risk, as it may go against the principle of decentralization that blockchains adhere to. However, Buterin is known to have a balanced view between decentralization and efficiency.
Conclusion
Vitalik Buterin, with his support for a Layer-2 solution by 2025, is likely to steer Ethereum in a more robust and efficient direction. This decision will accelerate the wider adoption of blockchain technology, make Ethereum a more competitive platform, and bring major changes to the crypto ecosystem as a whole.
