Blockchain
Only a few tasks have come near matching the safety and decentralization of the Ethereum community. Nonetheless, the inherent overhead of sustaining these two essential options has left Ethereum burdened by low throughput and prohibitively excessive prices. In consequence, various layer-1 blockchains (L1s) — which usually sacrifice safety and decentralization to offer 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 business, 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., enormous 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 vital 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 return.

There’s additionally the truth that Ethereum remains to be the main community in terms of the huge quantity of decentralized purposes, platforms and nonfungible tokens (NFTs) deployed on it, appearing because the go-to blockchain for all Web3 builders. Primarily, the market hasn’t seen any of those rivals — typically labeled “Ethereum killers” — really “kill” Ethereum (and even hurt it).
That mentioned, it’s comprehensible why alternate options have proliferated lately. Because it stands, Ethereum is deeply decentralized and safe, however it’s also comparatively sluggish 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, resembling sharding, will help this imaginative and prescient and make it extra highly effective.
ZK L2s are capable of course of a lot of transactions, and robotically generate mathematical proof of the validity of these transactions. That proof then will be submitted to Ethereum and verified by its validators, thus successfully providing the identical degree of safety as Ethereum. To make this superior know-how 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. Resulting from effectivity and complexity constraints, ZK L2s have been utilizing customized execution environments as an alternative of the acquainted and extensively used Ethereum Digital Machine. After a whole lot of exhausting work and spectacular cryptographic and engineering breakthroughs, builders managed to create zkEVM — an EVM-compatible ZK L2.

This superior know-how permits all Ethereum tasks to simply port current good contracts onto a zkEVM L2 with none modifications to their code, thus eradicating the final barrier for huge adoption. Till not too long ago, it was believed that full-featured zkEVMs have been nonetheless three to 5 years away, however current developments have significantly compressed that timeline, with the primary sensible implementation of the know-how already being deployed.
That is the important thing element that Ethereum has been lacking to offer larger utility at scale. Decentralized finance companies, NFT markets and Web3 gaming are actually possible for normal use and international adoption. Higher but, when the vital upcoming Ethereum upgrades get applied, zkEVMs solely stand to function much more successfully. All of this can additional set up Ethereum because the blockchain of selection for all sorts of decentralized tasks.
Do we want various layer 1s?
With the zkEVMs, there are not any boundaries with regard to scalability, safety, decentralization and developer expertise. This then begs a elementary query: Will we even want different L1 blockchains?
Ethereum already has the overwhelming majority of Web3 purposes constructed on prime of it. All different networks face an enormous uphill battle in the event that they hope to ever really 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 answer that already works.
Because of offering immense scaling potentialities, zkEVMs will also be leveraged to redefine what’s doable on Ethereum as an entire. To this point, prohibitively excessive transaction charges have incentivized purposes which might be both computationally environment friendly or fee-insensitive, probably leaving different revolutionary or vital tasks on the shelf as a consequence of these restrictions. Along with scaling current use instances, zkEVMs can breathe new life into these unexplored use instances, thus really turning into the endgame of Web3 infrastructure.
