When CryptoKitties crashed the Ethereum network in 2017, the industry learned a hard lesson about blockchain scalability. Today, with over $100 billion locked in decentralized finance (DeFi) and millions of non-fungible tokens (NFTs) being traded, that lesson is more relevant than ever. The Ethereum Virtual Machine (EVM) — the engine that powers this activity — is reaching its limits.
So far, the crypto community’s answer has been layer 2 solutions — separate chains that process transactions and report back to Ethereum. But what if the community’s been looking for answers in the wrong place?
Layer 2s are not the solution
Layer 2 blockchains have long been touted as the solution to the EVM’s performance challenges, given their ability to offload the computational work from Ethereum to a secondary chain. Layer-2 solutions have proven to be nothing more than a “quick fix” instead of a permanent solution, as many hoped for. As Gemini reported, a new layer 2 appeared every 19 days in 2024, indicating that the competitive landscape is creating more problems instead of solving them.
Layer 2 solutions come with their own challenges, primarily tied to centralization and interoperability. Many of today’s layer 2 blockchains run with centralized sequencers that could expose the network to transaction censorship, transaction reordering and more. Additionally, Vitalik Buterin stated in a recent blog post that layer 2s are struggling to maintain interoperability. This called attention to the disorganized state of layer 2s, further contributing to liquidity fragmentation and a complex user experience.
