Ethereum co-founder Vitalik Buterin delivered an essential message in regards to the Layer 2 ecosystem on the fourth Hong Kong Web3 Competition on April 20: copying Ethereum and making it extra centralized shouldn’t be a product; it’s a mistake.
Talking on the occasion, Buterin drew a distinction between two sorts of L2 tasks. The primary takes Ethereum, scales it up, and reduces decentralization within the course of. The second begins by inspecting what functions really want, identifies the off-chain parts these functions require past Ethereum’s base layer, and builds particularly to fulfill these wants.
His verdict on the primary kind was, “The kind of L2 that doesn’t make sense is while you simply take Ethereum, make a replica of Ethereum, make it 100 instances larger, make it extra centralized, and you’re completed.”
What an L2 Ought to Truly Do
Buterin’s argument is rooted in how helpful infrastructure will get constructed. Reasonably than beginning with Ethereum and asking easy methods to make it larger, he argued that significant L2 growth begins with functions and works backward.
“The kind of L2 that I feel is smart is while you begin to look by means of the functions, you ask what are the off-chain parts that they want, what are the components they want aside from the Ethereum L1, and you then construct,” he stated.
Two Scaling Priorities
Alongside his critique of copycat L2s, Buterin outlined the place Ethereum’s scaling focus must go subsequent. The primary precedence is information scaling. The latest Ethereum arduous fork launched PeerDAS expertise, considerably bettering the community’s potential to publish information on-chain. Buterin acknowledged the progress however was direct that the work is unfinished.
“We nonetheless have to push that additional,” he stated, signaling that information availability stays an energetic growth precedence fairly than a solved downside.
The second precedence is compute scaling. That is the place Buterin’s argument turns into significantly important for builders. “Scaling compute that’s a part of the Ethereum chain permits completely different functions to compose with one another, to speak to one another, with out requiring intermediaries,” he stated.
That composability is considered one of Ethereum’s defining architectural benefits. Compute scaling is what preserves it at a larger scale fairly than fragmenting the ecosystem throughout remoted chains that can’t work together effectively.
Why This Issues
The L2 ecosystem has grown, with dozens of chains launching on high of Ethereum’s safety layer. Buterin’s Hong Kong feedback recommend that not all of that development represents real worth creation.
Initiatives that replicate Ethereum’s construction with out addressing particular utility necessities are contributing noise fairly than infrastructure. Those that establish real gaps and construct exactly to fill them are those he believes are price constructing.
