His take? That\u2019s fine but developers should <strong>embrace Ethereum\u2019s foundational features<\/strong> instead of trying to rebuild them from scratch.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Build Smarter, Not Harder<\/h3>\n\n\n\n<p>According to Buterin, future Layer 2s don\u2019t need to be bloated with unnecessary infrastructure. Instead, they should <strong>focus on what L2s are really good at<\/strong>: sequencing transactions and generating cryptographic proofs like <strong>ZK-proofs or fraud proofs<\/strong> to validate execution.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><em>\u201cReduce your logic to just being a sequencer and a prover (if based, just a prover) over the core execution,\u201d<\/em> Buterin advised.<\/p>\n<\/blockquote>\n\n\n\n<p>He argues that developers should <strong>lean into Ethereum L1\u2019s baked-in strengths<\/strong> such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Security<\/strong><\/li>\n\n\n\n<li><strong>Censorship resistance<\/strong><\/li>\n\n\n\n<li><strong>Proof generation<\/strong><\/li>\n\n\n\n<li><strong>Data availability<\/strong><\/li>\n<\/ul>\n\n\n\n<p>By offloading these key features to Ethereum\u2019s base layer, builders can keep L2s <strong>lightweight, efficient, and robust<\/strong>, rather than trying to duplicate efforts already solved by Ethereum\u2019s architecture.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The Real-World Payoff<\/h3>\n\n\n\n<p>Vitalik didn\u2019t stop at theory. He highlighted <strong>real-world examples<\/strong> where Ethereum L1\u2019s properties have come to the rescue when something went wrong on an L2.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><em>\u201cWe\u2019ve already seen successful examples of the L1\u2019s features protecting users\u2019 rights if something on the L2 goes wrong,\u201d<\/em> he explained, underlining the practical security benefit of tying L2s closely to Ethereum\u2019s foundation.<\/p>\n<\/blockquote>\n\n\n\n<p>This philosophy is especially relevant in light of Buterin\u2019s broader push for <strong>true decentralization<\/strong> not just buzzword-level marketing. At the recent <strong>Ethereum Community Conference<\/strong>, he criticized many so-called decentralized apps for relying on centralized front ends, calling them \u201c<strong>straw houses<\/strong>.\u201d<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The Walkaway Test<\/h3>\n\n\n\n<p>To test whether a decentralized app is actually resilient, Buterin introduced what he called the <strong>\u201cwalkaway test\u201d<\/strong>: would the app still work if the original team completely disappeared?<\/p>\n\n\n\n<p>If the answer is no, the app likely isn\u2019t as decentralized or secure as it claims to be.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Bottom Line<\/h3>\n\n\n\n<p>Buterin\u2019s message is clear: L2 builders should <strong>ditch unnecessary complexity<\/strong>, embrace Ethereum\u2019s L1 strengths, and build systems that are <strong>truly decentralized and durable<\/strong>.<\/p>\n\n\n\n<p>In doing so, the Ethereum ecosystem can realize a long-standing dream: the fusion of <strong>trust minimization and efficiency<\/strong> that the blockchain space has been chasing since the early 2010s and now, finally, has the tools to achieve.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ethereum co-founder Vitalik Buterin has a message for the crypto developer community: when building Layer 2 solutions, stop overengineering and start using the full power of Ethereum\u2019s Layer 1.
