The “scaling wars” of Ethereum have been heating up this previous few months, and we’re now on the level the place over half the most important protocols have launched their zero-knowledge EVM (zkEVM) affords. zkEVMs herald the following period of scalability for Ethereum by utilising zero-knowledge proof know-how so as to present better transaction throughputs (~2000 tps is usually recommended) than is feasible utilizing different layer 2 applied sciences, akin to optimistic rollups.
This throughput is achieved by decreasing the quantity of knowledge that must be saved on the layer one community — the Ethereum mainnet which holds proof of the transactions contained within the rollup. That is versus optimistic rollups which require all transaction knowledge to be revealed on the layer one community. The better throughput is not the one advantage of zkEVMs, in addition they present a decrease transaction price, sooner finality and proof of the underlying computation happening.
The state of the ecosystem
2023 has seen plenty of exercise with zkEVM launches, and at first of April we’ve got:
The EVM in zkEVM
ZkEVMs are suitable with the EVM, the concept being that you would take any sensible contract code written in Solidity compile it to EVM byte code and run it on a zkEVM with out having to make any changes. In apply, many zkEVMs require a customized compiler to generate the bytecode executed by their zkEVM, and that is the place the approaches range between completely different groups.

Extra concerns
On prime of the compilation concerns, to make use of any of those networks, you will want to bridge Ether to them to pay for fuel charges. Then there may be the extra infrastructure utilized by layer 2 networks. All layer 2 networks have sequencers that are accountable for taking batches of transactions within the case of optimistic rollups, or proofs within the case of ZK rollups and writing them to the Ethereum mainnet.
zkEVM networks have the addition of provers that are accountable for creating the proofs of transactions which happen on the community.
Each sequencers and provers are at present centralised parts inside layer 2 networks. It’s anticipated that they may grow to be decentralised over time, however on the present time, they’re infrastructure sometimes operated by the groups behind the layer 2 community know-how. This is not a reason for competition at current, but it surely’s probably that there will be competitors between the varied groups to totally decentralise their infrastructure too.
The place to start out
With the entire exercise taking place with ZK know-how, it is thrilling, but additionally fairly daunting in case you’re contemplating which layer 2 community to work with.
As is evident from the 5 corporations listed above, the ecosystem continues to be very younger, with out clear leaders rising but from the zkEVM camps.
Referring to a number of the complete worth locked (TVL) metrics offered by l2beat, optimistic rollups Arbitrum One and Optimism account for round $8bn of the TVL on layer two networks, with the zkEVMs being within the low tons of or tens of million by way of TVL.

It will not keep this manner perpetually, however it’s a consideration of what would be the motivation for customers preferring zkEVM-based options over optimistic. There are clear technical advantages for zkEVMs, nevertheless, we all know that comfort and the switching prices will be excessive emigrate folks and groups to new applied sciences, so it could not occur as rapidly as some might imagine.
“Visa scale”
For groups seeking to launch new functions on public networks, the zkEVMs can be very enticing if they will comfortably deal with 2000 tps versus the tons of of tps that optimistic rollups can deal with.
This capacity to course of “Visa scale” transaction volumes will little doubt pave the best way for brand new courses of software on public networks and curiosity these corporations that have been constrained by the volumes offered by common blockchain networks.
Nevertheless, till clear winners emerge out of the present crop of zkEVMs groups might want to needless to say they might have to be keen emigrate down the road relying on how the panorama performs out.
As well as, there are the challenges related to interacting with these networks, the place funds have to be bridged to networks which aren’t as streamlined as they could possibly be.
ZK != non-public
Alternatively, we could begin seeing launches of zkEVM based mostly app-chains which use zk-rollup know-how to realize scale however anonymise their exercise by way of the proofs which are despatched to a public blockchain community. This can be a pattern that’s prone to collect traction, because it might present consortia to assist profit from a number of the safety ensures of the general public blockchain networks.
The primary takeaway is while there may be at present a flurry of exercise happening within the zkEVM house, it may take time for the know-how to mature and correctly decentralise.
Wen standardisation?
It is also helpful to distinction the method being taken right here with a number of groups constructing their very own layer 2 know-how stacks. They’re all making use of the Ethereum mainnet to inherit the safety and decentralisation ensures provided by this community.
Nevertheless, every layer2 networks is its personal particular person ecosystems. There may be commonality so far as they supply EVM compatibility in their very own methods, however in case you have one app on Linea and one other one on Scroll, there may be not going to be some extent the place the networks consolidate down the road, they may stay their very own separate entities.
This differs considerably from the method taken by the creation of Ethereum the place a number of groups have been working collectively to construct out a shared imaginative and prescient of a world decentralised community.
There isn’t a standardised method to constructing layer 2 networks. They’re being created in a bottom-up method to the Ethereum mainnet.
This brings with it a proliferation of albeit open, however nonetheless walled gardens with respect to how the completely different networks work. It additionally signifies that there can be an absence of consumer variety in lots of of those networks till they acquire important momentum.
It additionally offers important competitors between consumer groups to realize adoption themselves which is what we’re seeing now.
This is not a nasty factor, however we can’t know the way this method performs out contrasted with a extra top-down method akin to that taken by Polkadot.
In Polkadot, its mainnet — the relay chain, use a standardised method to launch their parachain networks that are roughly equal to layer2s on Ethereum. This implies there are fewer limitations to launching new networks and transacting between them, as all of them make use of Parity Applied sciences Substrate Framework.
Change is the one fixed
It’s nice to see the entire mainnet and testnet launches this previous month and momentum will proceed to construct as an increasing number of groups begin to construct on these platforms, however in case you’re making an attempt to select an L2 to double down on, if you should buy your self a while, it’s best to.
One factor we will say with certainty is that the panorama is prone to look fairly completely different in 12-18 months from now versus the place we’re proper now and now is just not the time to go all-in on one layer 2 in case you don’t need to.
