Ethereum scaling options supplier StarkWare is taking issues a step additional with know-how to help in additional scaling of Layer 1 and a couple of networks.
In a weblog submit on Dec 21, StarkWare unveiled “Fractal Scaling” from Layer 2 to Layer 3. The agency, which already scales Ethereum utilizing zero-knowledge (ZK) rollups, is already planning to construct on prime of this infrastructure with Layer 3.
StarkWare stated that almost all of Ethereum exercise shall be on Layer 2 within the close to future because of the prohibitive prices of transactions on L1. It added that some functions want particular tailoring which might be higher served by a brand new layer – 3.
Layer 3 will relate to L2 simply as L2 does to L1. It shall be constructed on prime of the StarkNet L2 platform to offer “hyper-scalability” additional decreasing Ethereum community charges.
StarkWare defined that the system that gives the proofs to L1 may also be used to offer proofs to L2 from one other layer;
When the L2 additionally makes use of validity proofs submitted to L1, as StarkNet does, this turns into an especially elegant recursive construction the place the compression good thing about L2 proofs is multiplied by the compression good thing about L3 proofs.
It added that if L2 can obtain a hypothetical value discount of 1,000x, then L3 can attain a a million instances discount over L1 whereas nonetheless retaining its safety.
StarkWare co-founder and President Eli Ben-Sasson mentioned Validium, which is a hybrid scaling resolution that maintains the information off-chain. Validium additionally makes use of zk-rollups to batch and implement transactions however on this case, it will likely be used to offer custom-made knowledge availability fashions for L3.
Another benefit is a discount in the price of on/off ramping between L1 and L2, which remains to be costly. A 3rd layer will present cheaper and less complicated interoperability and it may also be used as a “canary community” for L2 functions earlier than they’re launched.
The agency acknowledged that StarkEx is presently working as an L2 however shall be ported to L3, earlier than concluding:
L3 guarantees hyper scalability, higher management of the know-how stack for varied wants, and privateness, whereas sustaining the safety ensures supplied by Ethereum (L1).
Layer 2 ecosystem outlook
The L2 ecosystem has exploded this yr as Ethereum L1 gasoline prices have surged. At the time of press, there was $5.4 billion locked throughout all L2 networks based on L2beat.
This represents a rise of 11,200% thus far this yr and is about the identical as your entire DeFi TVL was in August 2020.
