Whereas Ethereum-based layer-2 options have been targeted on hyperscaling the community, Ethereum co-founder Vitalik Buterin believes layer 3s will serve a far totally different objective — offering “personalized performance.”
Buterin shared his ideas in a Saturday put up, offering three “visions” of what layer 3s shall be used for sooner or later.
The Ethereum co-founder stated a 3rd layer on the blockchain is smart provided that it offers a unique operate to layer 2s, which have been used primarily to reinforce scaling by way of zero-knowledge (zk) Rollup expertise:
“A 3-layer scaling structure that consists of stacking the identical scaling scheme on high of itself typically doesn’t work effectively. Rollups on high of rollups, the place the 2 layers of rollups use the identical expertise, actually don’t.”
However, “a three-layer structure the place the second layer and third layer have totally different functions, nevertheless, can work,” stated Buterin.
One in every of layer 3’s use circumstances can be what Buterin describes as “personalized performance” — referencing privacy-based purposes which might make the most of zk proofs to submit privacy-preserving transactions to layer 2.
One other use case can be “personalized scaling” for specialised purposes that don’t wish to use the Ethereum Digital Machine (EVM) to do computation.
Buterin additionally stated that layer 3 might be used for “weakly-trusted” scaling via Validiums, a zk-proof expertise. Buterin stated this can be helpful for “enterprise blockchain” purposes by utilizing “a centralized server that runs a validium prover and frequently commits hashes to chain.”
However, Buterin added that it’s nonetheless unclear whether or not layer-3 buildings shall be extra environment friendly than the present layer-2 mannequin in the case of constructing personalized purposes on Ethereum.

“One potential argument for the three-layer mannequin over the two-layer mannequin is: a three-layer mannequin permits a complete sub-ecosystem to exist inside a single rollup, which permits cross-domain operations inside that ecosystem to occur very cheaply, with no need to undergo the costly layer 1,” Buterin stated.
However, Buterin stated that as a result of cross-chain transactions might be executed simply and cheaply between two layer 2s which have dedicated to the identical chain, constructing layer 3s could not essentially enhance the effectivity of the community.
Buterin’s feedback on potential layer 3 use circumstances come as StarkWare’s newly produced recursive validity proofs seem to have presumably put an finish to Ethereum’s scalability considerations.
Declan Fox, the product supervisor at Ethereum software program agency ConsenSys, lately informed Cointelegraph that “with recursive rollups and proofs, we theoretically can infinitely scale.”
These recursive proofs have been effectively examined in manufacturing, with StarkWare co-founder Eli-Ben Sasson lately telling Cointelegraph that its recursive proofs have rolled up as many as 600,000 nonfungible token mints in a single transaction on Immutable X and that 60 million transactions might quickly be on the playing cards “with extra engineering and tweaking.”
