Only a few initiatives have come near matching the safety and decentralization of the Ethereum community. Nonetheless, the inherent overhead of sustaining these two crucial options has left Ethereum burdened by low throughput and prohibitively excessive prices. Because of this, various layer-1 blockchains (L1s) — which usually sacrifice safety and decentralization to supply scale — have emerged to nip away at Ethereum’s market share.
Nonetheless, with Ethereum Digital Machine (EVM)-equivalent scaling options bringing excessive throughput and low transaction charges to Ethereum itself, the query is: Do we actually want these various L1 networks?
Regardless of a rocky 12 months for the trade, Ethereum remains to be as robust as ever
The dangers of sacrificing safety and decentralization have been largely materialized with various L1s this 12 months. These blockchains and their communities have been experiencing downtimes, censorship, giant hacks and existential challenges brought on by centralized token provide — i.e., large parts of tokens held by malicious people. Within the meantime, the Ethereum ecosystem has had one other good 12 months.
For starters, we’ve seen the long-awaited improve of the Ethereum blockchain from proof-of-work to proof-of-stake after its September “Merge.” This was essential for a number of causes, together with that it led to an enormous discount within the vitality utilization of the community. It additionally set the stage for additional scaling options within the months and years to come back.

There’s additionally the truth that Ethereum remains to be the main community on the subject of the huge quantity of decentralized purposes, platforms and nonfungible tokens (NFTs) deployed on it, performing because the go-to blockchain for all Web3 builders. Primarily, the market hasn’t seen any of those opponents — usually labeled “Ethereum killers” — really “kill” Ethereum (and even hurt it).
That stated, it’s comprehensible why alternate options have proliferated in recent times. Because it stands, Ethereum is deeply decentralized and safe, however it is usually comparatively gradual and costly to make use of.
Making Ethereum work
To mitigate the aforementioned challenges with out vital tradeoffs, Ethereum has now successfully ceded execution to layer-2 options (L2s). Even Ethereum founder Vitalik Buterin has famous that layer-2 zero-knowledge (ZK) options are the way forward for Ethereum scaling. He has additionally acknowledged that additional Ethereum enhancements, akin to sharding, will assist this imaginative and prescient and make it extra highly effective.
ZK L2s are in a position to course of a lot of transactions, and mechanically generate mathematical proof of the validity of these transactions. That proof then might be submitted to Ethereum and verified by its validators, thus successfully providing the identical degree of safety as Ethereum. To make this superior expertise much more interesting, these proofs would not have to disclose details about the precise transactions, thus enabling privateness of transactions when required.
ZK L2s have been round for greater than a 12 months, however wider adoption has been hindered primarily by suboptimal developer expertise. As a result of effectivity and complexity constraints, ZK L2s have been utilizing customized execution environments as a substitute of the acquainted and broadly used Ethereum Digital Machine. After a number of laborious work and spectacular cryptographic and engineering breakthroughs, builders managed to create zkEVM — an EVM-compatible ZK L2.

This superior expertise permits all Ethereum initiatives to simply port present sensible contracts onto a zkEVM L2 with none modifications to their code, thus eradicating the final barrier for vast adoption. Till just lately, it was believed that full-featured zkEVMs had been nonetheless three to 5 years away, however latest developments have significantly compressed that timeline, with the primary sensible implementation of the expertise already being deployed.
That is the important thing part that Ethereum has been lacking to supply higher utility at scale. Decentralized finance companies, NFT markets and Web3 gaming are actually possible for normal use and world adoption. Higher but, when the essential upcoming Ethereum upgrades get carried out, zkEVMs solely stand to function much more successfully. All of this can additional set up Ethereum because the blockchain of selection for every type of decentralized initiatives.
Do we’d like various layer 1s?
With the zkEVMs, there are not any boundaries with regard to scalability, safety, decentralization and developer expertise. This then begs a basic query: Can we even want different L1 blockchains?
Ethereum already has the overwhelming majority of Web3 purposes constructed on high of it. All different networks face a large uphill battle in the event that they hope to ever actually compete with that. Even with an ideal community that addresses all scaling and safety points whereas staying decentralized, any various L1 will nonetheless be making an attempt to claw customers away from a longtime resolution that already works.
Because of offering immense scaling potentialities, zkEVMs can be leveraged to redefine what’s potential on Ethereum as a complete. To this point, prohibitively excessive transaction charges have incentivized purposes which are both computationally environment friendly or fee-insensitive, doubtlessly leaving different progressive or essential initiatives on the shelf because of these restrictions. Along with scaling present use circumstances, zkEVMs can breathe new life into these unexplored use circumstances, thus actually changing into the endgame of Web3 infrastructure.
