Ethereum has seen large development this 12 months with the community now supporting over 2,000 decentralized purposes (dApps) spanning decentralized finance (DeFi), non-fungible tokens (NFTs), gaming and extra, in line with State of the DApps.
The variety of Ethereum customers has additionally soared. Monthly energetic customers of the MetaMask non-custodial pockets product have surpassed 21 million — a 38-fold improve from 2020. There are actually 3.4 million Ethereum addresses interacting with DeFi protocols and over US$170 billion in whole worth locked in DeFi protocols, in line with DeFi Llama.
But Ethereum’s increasing ecosystem and recognition have additionally resulted in skyrocketing transaction charges and considerations that Ethereum’s scalability points have made it cost-prohibitive for mainstream customers.
Although competitor blockchains resembling Binance Smart Chain, Solana, Cardano and Polkadot have emerged, Ethereum nonetheless stays the dominant sensible contract platform given its community impact and the technical funding by tasks and builders.
Layer 2 — the way forward for Ethereum scaling
A myriad of options are being developed to scale Ethereum, with the principle purpose to extend transaction velocity and transaction throughput, with out compromising decentralization or safety. Eth 2, a multi-year, multi-phase sequence of upgrades that features Ethereum’s transition to a proof-of-stake community and shard chains, plans to make Ethereum extra scalable, safer, and extra sustainable. However, Ethereum base-layer scalability for purposes stays years away.
Layer-2 tasks, a collective time period for options designed to scale Ethereum by dealing with transactions off the mainnet whereas counting on Ethereum’s decentralized consensus mechanism for safety, is a rising development. Rollups, a Layer-2 resolution, are designed to decongest the Ethereum community by bundling (or “roll-up”) transactions collectively, compressing and processing them off-chain, earlier than sending the outcomes again to Ethereum, leading to improved velocity and considerably decrease transaction prices.
In a current speech on the 2021 Shanghai International Blockchain Week, Ethereum creator Vitalik Buterin mentioned Layer 2 is the way forward for Ethereum scaling and the one protected method to scale Ethereum whereas preserving decentralization that’s so core to the blockchain.

Rollups take two varieties: “Optimistic rollups” that assume transactions are legitimate and solely execute the computation if a fraudulent transaction is suspected, and “zero-knowledge rollups” (ZK rollups) that bundle the transactions for processing off-chain and submit a validity proof to the Ethereum community verifying that the transactions are legitimate. It is estimated that optimistic rollups can supply as much as 10 to 100 instances enhancements in scalability relying on the transaction.
Why Arbitrum is main Ethereum scaling
Arbitrum, a layer-2 optimistic rollup resolution constructed on Etherum by Off-chain Labs, at present leads layer-2 utilization, with a market share of 41% and whole worth locked of over US$2.72 billion, in line with L2 Beat, which tracks layer-2 tasks.
Blockchain analytics platform Nansen sees Arbitrum main the wave of Ethereum scalability options within the close to future with builders more and more constructing on it.
“Arbitrum is the most Ethereum Virtual Machine (EVM) compatible layer 2 as of today. This makes it almost trivial for developers to migrate existing Ethereum applications to rollups because they don’t have to rewrite the code,” Nansen wrote in a analysis report on Arbitrum revealed this week.
Arbitrum permits for 40,000 transactions per second (TPS), considerably greater than Ethereum’s 15 to 30 TPS for Ethereum. Transaction charges on Arbitrum are at present about thrice decrease in comparison with utilizing the Ethereum base layer (US$3.46 on Arbitrum One vs. US$11.17 on Ethereum as of publishing time, in line with L2 charges.)
Attracted by decrease transaction prices, customers are turning to Arbitrum when utilizing dApps on Ethereum that require transactions resembling Aave and Uniswap. This could possibly be achieved by including the Arbitrum One community extension to the MetaMask pockets. Centralized cryptocurrency exchanges resembling Binance and Crypto.com have additionally not too long ago added assist for Arbitrum. There are at present 280,000 distinctive addresses on Arbitrum — a rise of over 4,000% because the starting of September.
The crypto whales, too, are interacting with Arbitrum. Half of “ETH Millionaires” — addresses with an Ether (ETH) steadiness of not less than US$1 million — that use Ethereum additionally use Arbitrum, in line with Nansen knowledge. Over 3.66 million transactions have been processed on Arbitrum, with a peak of over 267,608 day by day transactions on Sept. 12, in line with Arbiscan.
Although optimistic rollups like Arbitrum, Boba Network and Optimism promise a lot by way of enhancing Ethereum’s scalability, they’re nonetheless at an early stage of growth. Current challenges embody a protracted withdrawal time, the place withdrawals can take as much as seven days resulting from potential fraud disputes, lack of interoperability and the fragmentation of liquidity between the totally different rollups, in line with Nansen’s report.
Optimistic rollups could also be most well-liked within the brief time period as they’re easier and simpler to construct, in line with Ethereum’s creator Buterin. But ZK rollups, however their complexity, could prevail as a greater technical resolution in the long term given their sooner finality time and stronger safety.
Polygon, a layer-2 Ethereum scaling platform, this month introduced the launch of Polygon Miden, which makes use of superior zero-knowledge cryptography to boost the scalability, privateness and safety of Polygon and Ethereum.
Most rollups resembling Arbitrum at present would not have native tokens, however Nansen predicts that almost all rollups will finally launch one. Loopring, a ZK rollup for buying and selling and fee that allows decentralized exchanges to course of hundreds of requests in batches off-chain with zero-knowledge proofs, has seen the worth of its Loopring (LRC) native token surge near 400% this month amid the hype over rollups.
As blockchain adoption grows, Nansen expects different layer-1 blockchains to start out constructing rollups on high of their mainnet in the long term.
“Beyond Ethereum, rollups is a paradigm that will be exported to other competing L1 and fuse in an increasingly complex landscape of scaling solutions,” Nansen wrote. “For everyone in crypto, L2s like Arbitrum are not just an investment question, they are the basis to ongoing and future projects in DeFi, the NFT space; will sustain DAOs and virtual worlds, but also support the entire creator economy and the Metaverse.”
