Ethereum’s Co-Founder Vitalik Buterin Shares What Layer-3 Could Look Like

Vitalik Buterin, Co-Founder of Ethereum, which recently migrated to the Proof of Stake (PoS) model, is already thinking about Layer-3, sharing what he believes could be the future of blockchain scaling.

Buterin on Layer 3

The base layer of a blockchain network, such as Ethereum, Cardano, or Solana, is referred to as “Layer-1”, while “Layer-2” solutions are built on Layer-1 blockchains to provide better scalability for the base layer. 

Buterin believes that a Layer-3 solution would only make sense if used for purposes other than scaling. For this reason, Layer-3 solutions should not consist of stacked rollups, as it would lead to inefficient data compression.

Buterin Shares His Vision for Layer-3 Solutions

In a blog post titledWhat kind of layer 3s make sense?” Buterin explained that Layer-3 solutions could be implemented in privacy-focused chains by utilizing zk proofs to submit private transactions to Layer-2.

According to Buterin, Layer-3 solutions can also be built around non-EVM platforms, using customized scaling solutions for specific applications or validiums (which are another kind of roll-up).

Buterin’s comments on potential Layer-3 use cases come as StarkWare’s newly produced, recursive validity proofs appear to have put an end to Ethereum’s scalability concerns.

On the Flipside

Vitalik Buterin also argues that decentralized autonomous organizations (DAOs) shouldn’t resemble corporations.

Why You Should Care

Since Layer-2 solutions on theperform efficient cross-border transactions on their respective networks, Layer-3 formats may not actively improve efficiency.
