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 is just not a product; it’s a mistake.
Talking on the occasion, Buterin drew a distinction between two sorts of L2 initiatives. 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 elements these functions require past Ethereum’s base layer, and builds particularly to fulfill these wants.
His verdict on the primary sort was, “The kind of L2 that doesn’t make sense is while you simply take Ethereum, make a duplicate 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. Fairly than beginning with Ethereum and asking the best way to make it larger, he argued that significant L2 improvement begins with functions and works backward.
“The kind of L2 that I feel is smart is while you begin to look by the functions, you ask what are the off-chain elements that they want, what are the components they want apart from the Ethereum L1, and then you definately construct,” he mentioned.
Two Scaling Priorities
Alongside his critique of copycat L2s, Buterin outlined the place Ethereum’s scaling focus must go subsequent. The primary precedence is knowledge scaling. The latest Ethereum laborious fork launched PeerDAS expertise, considerably enhancing the community’s potential to publish knowledge on-chain. Buterin acknowledged the progress however was direct that the work is unfinished.
“We nonetheless must push that additional,” he mentioned, signaling that knowledge availability stays an lively improvement precedence slightly than a solved drawback.
The second precedence is compute scaling. That is the place Buterin’s argument turns into notably important for builders. “Scaling compute that’s a part of the Ethereum chain permits totally different functions to compose with one another, to speak to one another, with out requiring intermediaries,” he mentioned.
That composability is one among Ethereum’s defining architectural benefits. Compute scaling is what preserves it at a larger scale slightly 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 progress represents real worth creation.
Tasks that replicate Ethereum’s construction with out addressing particular software necessities are contributing noise slightly than infrastructure. Those that determine real gaps and construct exactly to fill them are those he believes are value constructing.
