  • Ethereum co-founder Vitalik Buterin believes Layer 3 will be very important in the future and shares three visions for its use cases.
  • This could play a huge role in SEO for privacy-based apps that would use zk evidence to submit privacy.

Ethereum co-founder Vitalik Buterin recently Publish observed that the concept of Layer 3 is usually in discussions about scaling Layer 2. In short, Buterin said that the Layer 2 solution is much more focused on hyper-scale in the network . However, Layer 3 would provide custom functionality. According to him, the consideration for layer 3 is very important because it plays different functions from layer 2.

A three-layer scaling architecture that involves piling the same scaling scheme on top of itself usually doesn’t work well. Rollups on top of rollups, where both layers of rollups use the same technology, certainly don’t. A three-layer architecture where the second layer and the third layer have different purposes can work, however.

Buterin thinks Layer 3 would be very important in the future, sharing three visions for its use cases. This could play a huge role in SEO for privacy-based apps that would use zk evidence to submit privacy. He described it as a “custom feature”.

Additionally, custom scaling for specialized applications that do not want to use the Ethereum Virtual Machine (EVM) for compute would be another use case for Layer 3 in the future. It could also be used for zk-proof technology, “poorly reliable” scaling via Validiums. According to him, they can be important for “enterprise blockchain” applications. It’s using “a centralized server that runs a validium prover and regularly validates hashes to chain.”

Cross-Chain Transactions Could Be Easily Executed Between Two Layer 2s – Ethereum Co-Founder

Either way, it’s not clear if the Layer 3 structure would be more efficient than the Layer 2 models.

A possible argument for the three-layer model versus the two-layer model is: a three-layer model allows an entire sub-ecosystem to exist in a single aggregation, which allows cross-domain operations within that ecosystem to happen very cheaply, without the need to go through the expensive layer 1.

Buterin also mentioned that cross-chain transactions can be executed easily and cheaply between two layers 2 engaged in the same chain. However, creating Layer 3s does not necessarily make the network more efficient. It is important to note that the recursive validity proofs newly produced by StarkWare no longer concern themselves with the Ethereum Scalability. Declan Fox, the product manager of Ethereum software company ConsenSys, also believes that it’s theoretically possible to scale infinitely with recursive roll-ups and proofs.

StarkWare co-founder Eli-Ben Sasson revealed that 600,000 non-fungible tokens (NFTs) minted in a single transaction on Immutable X were accumulated by his recursive proofs.

The implementation is expected to increase the demand for ETH to tame the selling pressure in the market. This, coupled with its major upgrade, the asset could maintain a price of around $4,000 by the end of the year.
