Vitalik Buterin, Ethereum’s Co-founder Shares What Layer 3 Would Look Like

Vitalik Buterin, the co-founder of , which recently migrated to Proof-of-Stake (PoS) is already thinking about Layer 3, sharing what he believes would be the future of blockchain scaling.

Buterin on Layer 3

The base layer of a blockchain network such as Ethereum, , or , is referred to as Layer 1. 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 different purposes other than scaling. Hence, layer 3 solutions cannot consist of stacked rollups as it would lead to inefficient data compression.

Buterin Shares His Vision for Layer 3 Solutions

In a blog post titled “What kind of layer 3s make sense?” Buterin explained that Layer 3 solutions can 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, customized scaling solutions for specific applications, or validiums (which are another kind of roll-up).

Buterin’s comments on possible layer 3 use cases come as StarkWare’s newly produced recursive validity proofs appear to have possibly put an end to Ethereum’s scalability concerns.

On the Flipside

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

Why You Should Care

Since layer 2 solutions on the same network efficiently perform cross-border transactions, layer 3s may not improve the efficiency of the network.
