Vitalik Buterin, the co-founder of Ethereum, is hesitant about incorporating all advanced functionalities that developers desire on Layer 2 scaling solutions. Many opt for L2 solutions like Optimism, Polygon, and Arbitrum due to their cost-effectiveness and speed compared to Ethereum mainnet. As of now, L2s are handling around 75 transactions per second, while Ethereum mainnet only manages a consistent 12 TPS, as reported by L2Beat. In essence, L2s benefit from the security assurances provided by the underlying L1 network. Buterin explained that when advanced functions are added on top of layer 2 rather than the primary layer, it can create additional risks. He stated that if there is a failure in the consensus of the primary layer, there may be some disruptions initially, but eventually things will be resolved. People could lose a significant amount of money permanently due to an L2 bug. He was responding to and generally in agreement with a tweet from a Bitcoin Magazine editor that criticized individuals who exaggerate the abilities of Layer 2 solutions. He suggested that it may be beneficial to incorporate advanced features at the base layer to streamline the development of Layer 2 solutions and make them easier to use. Lately, Buterin has been particularly concentrated on enhancing security and ensuring the safety of users on the Ethereum network. He recently mentioned his interest in utilizing AI technology to assist developers in auditing Ethereum’s code and identifying bugs. The increased emphasis on security, which was the topic of his latest blog post, may explain why he has shifted his viewpoint on L2s. In the past, he supported the idea of keeping the Ethereum mainnet as uncomplicated as possible. At a Ethereum meetup in Taipei in 2019, Buterin shared his views on scaling solutions, suggesting that there is no need for the first layer to be overly complicated in order to optimize its properties. He also stated that modifying L1s would become progressively more challenging as time passes. His remarks were made shortly before the Dencun upgrade is launched on the Ethereum mainnet.
