Layer 2s have been an awesome blockchain success story. They’ve lowered congestion on the Ethereum mainnet, driving down fuel charges whereas preserving safety.
However possibly they’ve develop into too profitable, drawing chain exercise and payment earnings from the mother or father that spawned them? No less than that’s what some are suggesting these days, most just lately at Cornell Tech’s blockchain convention in late April.
Certainly, some suppose Ethereum needs to be a bit of greedier, or at the least battle tougher for an even bigger a part of the income pie, notably sequencing charges.
“Individuals within the Ethereum Basis [the nonprofit that supports the Ethereum ecosystem] will inform you that, ‘Sure, we effed up by being too ivory tower.’ I’ve heard that a number of instances,” mentioned David Hoffman, an proprietor at Bankless, throughout a panel dialogue on the Cornell Tech occasion in New York Metropolis on April 25.
Elsewhere, Hoffman has urged Ethereum to make a “strategic pivot,” noting that the crypto setting has modified in the previous couple of years. Ethereum now not has the “luxurious of being a peace-time analysis mission…. exploited by its competitors.”
L2s are reaping thousands and thousands of {dollars} in transaction order charges (generally referred to as sequencing charges), however none of those revenues are being handed on to Ethereum, in keeping with James Beck, head of development at ENS Labs and one other speaker on the New York Metropolis convention. Beck advised Cointelegraph:
So, this cultural layer of podcasters and researchers are saying, ‘Properly, the worth of ETH has been dropping in comparison with these different tokens. What will we do to make Ethereum extra highly effective?’
Briefly, Ethereum is a impartial verification layer, however the Ethereum mainnet will not be being pretty compensated for the work that it’s doing. Centralized for-profit L2s like Base, Optimism and Arbitrum are gathering the profitable sequencing charges whereas having fun with the safety and liveness ensures of the Ethereum mainnet at comparatively little financial price.
L2s soared after Dencun improve
L2 rollups are a current innovation; they solely emerged in 2023. The thought was to cut back chain congestion and fuel charges by transferring transaction processing from the primary blockchain (layer 1) to separate chains that sit atop the mainnet (L2s). However transaction processing is arguably essentially the most worthwhile a part of the income sport, particularly when customers decide to pay precedence charges to get their orders processed quicker.
Price-sharing was hardly ever a lot of a difficulty earlier than Ethereum’s March 2024 Dencun improve, which launched blob transactions to assist scale layer 2s. Blobs considerably lowered the fee for L2s to publish information to Ethereum, permitting them to function extra profitably, CoinMetrics researcher analyst Tanay Ved advised Cointelegraph this week.
Since then, L2 consumer demand has soared, particularly on Base, the L2 launched by Coinbase in August 2023 on the Ethereum mainnet.
As Ved famous in an April 8 weblog, Base has earned a complete of ~$98 million in revenues from user-transaction charges (together with base and precedence charges), “whereas paying solely ~$4.9M to the Ethereum base layer, leading to a complete estimated revenue of $94M for the reason that Dencun improve.”
Ved added:
This dynamic has led to many questioning whether or not Layer-2s are web optimistic for Ethereum, or whether or not they’re ‘extractive.
Base’s response
Requested about charges, a Base spokesperson advised Cointelegraph, “Immediately, Base already pays Ethereum charges for each transaction on Base. All transactions are settled on Ethereum, and to this point, Base has paid Ethereum greater than $20 million in settlement charges since Base’s inception.” One can see these charges on Token Terminal beneath “price of income,” the spokesperson added.
“General, Base makes getting onchain extra accessible with quick and low-cost transactions and helps develop the Ethereum ecosystem by onboarding extra customers, builders, apps and belongings, all of whom are transacting in ETH and driving demand,” mentioned the spokesperson.

Nonetheless, in lots of, if not most months, Base’s total charges are roughly 10 instances the quantity paid to Ethereum for settling trades, in keeping with examination of the referenced Base monetary assertion. In April, as an example, the newest full month, Base reaped $3.7 million in charges, however solely $305,000 was delivered to Ethereum as settlement charges — about 8% of complete charges.
Nonetheless, possibly issues aren’t fairly so dire. Even when charges are out of kilter now, the imbalance might not final, others warning. Ethereum exhausting forks like Pectra, which went stay yesterday (Could 7), and Fusaka, scheduled for late 2025, will improve blob throughput. “This implies L2s will have the ability to publish extra blobs, probably driving greater complete blob charges to mainnet,” Ved advised Cointelegraph.
Ethereum is already constantly hitting the present blob goal of three per block, because the chart beneath exhibits. “Pectra will elevate this to 6 blobs per block — with a max of 9 — creating room for elevated payment seize as L2 exercise scales,” added Ved.
Are “based mostly rollups” the reply?
Some Ethereum researchers, podcasters — and even L2s — have been leaning into “based mostly rollups” as a extra everlasting method to repair the payment drawback and supply higher safety within the cut price. Right here, transaction ordering (i.e., sequencing) can be carried out on the mainnet, not on L2s.
The sequencers utilized by Optimism, Arbitrum One, Base and others are extra liable to assault or failure, provided that they’re centralized, with a single level of failure, some researchers say. Polygon’s Jarrod Ward writes:
If a centralized sequencer goes down, the rollup successfully stops doing its job solely. It stops dealing with transactions from customers on the L2 and in addition stops sending batch information again to Ethereum.
“Layer-2 sequencers have develop into dangerously centralized,” added Tom Ngo, government lead at Metis — an Ethereum layer-2 blockchain.
Final June’s $2.6-million hack of Ethereum layer-2 blockchain Linea drove residence to Ngo and others the significance of decentralization and the perils of centralized sequencers.

A number of based-rollup L2s have launched this previous yr. Taiko Alethia, the primary and largest, went stay in Could 2024. A yr later, it had $148.3 million in complete worth secured — rating 14th on L2Beat’s listing of L2s, although far behind chief Base’s $12.06 billion.
Speedwise, Taiko was averaging a good 20.3 consumer operations per second (UOPS) on Could 7, a far cry from Base’s 86.3 UOPS, however on par with Arbitrum One’s (21.6 UOPS) and considerably higher than Optimism’s (10.3 UOPS).
A tax on L2s?
One other concept floated within the Ethereum group is imposing a form of tax on L2s. However doing this might have some unintended penalties, in keeping with Ved. It may make L2s much less aggressive. It additionally dangers “leakage of exercise to competing layer 1s exterior the Ethereum ecosystem.” Exercise that flows to Base at this time may movement as a substitute to Solana or different L1s, Ved mentioned.
There might be philosophical points, too, have been Ethereum to put a surcharge on its L2s. Ved famous:
A tax might be seen as opposite to Ethereum’s ethos of decentralization, which might go for market-driven forces slightly than implementing a tax.
Usually talking, the Ethereum Basis appears to be prioritizing long-term development over short-term income, Ved defined. Proposals like EIP-7762, although, which raises the minimal blob base payment to hurry up worth discovery throughout demand surges, may drive extra payment earnings to Ethereum mainnet, having an impact like a tax.
Social stress?
In accordance with ENS Labs’ Beck, it might take some social stress to get the main centralized L2s to voluntarily hand over their sequencing charges. Different L2s like Linea might must step in and say to centralized L2s one thing alongside the strains of: “Look, you guys have these dangers inherent in a extra centralized design, and right here’s the prospect to bake [the order processing] into Ethereum, which is extra decentralized.”
Alongside these strains, ENS took half in a three-day workshop within the UK in January with main researchers and builders from entities like Linea, Standing, OpenZeppelin, Titan, Spire Labs and the Ethereum Basis. The instant process was the way to create scalable, decentralized infrastructure for ENS Labs’ Namechain, but in addition to carry collectively numerous Ethereum ecosystem groups to collaboratively remedy L2 interoperability challenges with based mostly…
