Layer 2s have been an important blockchain success story. They’ve lowered congestion on the Ethereum mainnet, driving down fuel charges whereas preserving safety.
However possibly they’ve change into too profitable, drawing chain exercise and price earnings from the mum or dad that spawned them? A minimum of that’s what some are suggesting recently, most lately at Cornell Tech’s blockchain convention in late April.
Certainly, some suppose Ethereum ought to be somewhat greedier, or at the very least combat more durable for a much bigger a part of the income pie, notably sequencing charges.
“Folks within the Ethereum Basis [the nonprofit that supports the Ethereum ecosystem] will let you know that, ‘Sure, we effed up by being too ivory tower.’ I’ve heard that a number of instances,” stated 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 few years. Ethereum now not has the “luxurious of being a peace-time analysis undertaking…. exploited by its competitors.”
L2s are reaping tens of millions of {dollars} in transaction order charges (typically referred to as sequencing charges), however none of those revenues are being handed on to Ethereum, in accordance with James Beck, head of progress 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, ‘Effectively, 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 isn’t 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 value.
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 recreation, particularly when customers decide to pay precedence charges to get their orders processed quicker.
Charge-sharing was not often 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 put up information to Ethereum, permitting them to function extra profitably, CoinMetrics researcher analyst Tanay Ved advised Cointelegraph this week.
Since then, L2 person 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 because the 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, “In the present day, Base already pays Ethereum charges for each transaction on Base. All transactions are settled on Ethereum, and up to now, Base has paid Ethereum greater than $20 million in settlement charges since Base’s inception.” One can see these charges on Token Terminal below “value of income,” the spokesperson added.
“Total, 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,” stated the spokesperson.

Nevertheless, in lots of, if not most months, Base’s general charges are roughly 10 instances the quantity paid to Ethereum for settling trades, in accordance with examination of the referenced Base monetary assertion. In April, as an illustration, the latest full month, Base reaped $3.7 million in charges, however solely $305,000 was delivered to Ethereum as settlement charges — about 8% of whole charges.
Nonetheless, possibly issues aren’t fairly so dire. Even when charges are out of kilter now, the imbalance could not final, others warning. Ethereum laborious forks like Pectra, which went dwell yesterday (Might 7), and Fusaka, scheduled for late 2025, will enhance blob throughput. “This implies L2s will be capable of put up extra blobs, probably driving increased whole blob charges to mainnet,” Ved advised Cointelegraph.
Ethereum is already constantly hitting the present blob goal of three per block, because the chart under reveals. “Pectra will elevate this to 6 blobs per block — with a max of 9 — creating room for elevated price 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 approach to repair the price drawback and supply higher safety within the discount. Right here, transaction ordering (i.e., sequencing) could be carried out on the mainnet, not on L2s.
The sequencers utilized by Optimism, Arbitrum One, Base and others are extra vulnerable 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 change into dangerously centralized,” added Tom Ngo, govt lead at Metis — an Ethereum layer-2 blockchain.
Final June’s $2.6-million hack of Ethereum layer-2 blockchain Linea drove house to Ngo and others the significance of decentralization and the perils of centralized sequencers.

A number of based-rollup L2s have launched this previous 12 months. Taiko Alethia, the primary and largest, went dwell in Might 2024. A 12 months later, it had $148.3 million in whole 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 person operations per second (UOPS) on Might 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 type of tax on L2s. However doing this might have some unintended penalties, in accordance with Ved. It might 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 present might circulate as an alternative to Solana or different L1s, Ved stated.
There could possibly be philosophical points, too, had been Ethereum to put a surcharge on its L2s. Ved famous:
A tax could possibly be seen as opposite to Ethereum’s ethos of decentralization, which might go for market-driven forces reasonably than implementing a tax.
Usually talking, the Ethereum Basis appears to be prioritizing long-term progress over short-term income, Ved defined. Proposals like EIP-7762, although, which raises the minimal blob base price to hurry up value discovery throughout demand surges, might drive extra price earnings to Ethereum mainnet, having an impact like a tax.
Social strain?
In response to ENS Labs’ Beck, it could take some social strain to get the main centralized L2s to voluntarily hand over their sequencing charges. Different L2s like Linea could have to step in and say to centralized L2s one thing alongside the traces 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 traces, 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 rapid process was how one can create scalable, decentralized infrastructure for ENS Labs’ Namechain, but additionally to carry collectively numerous Ethereum ecosystem groups to collaboratively resolve L2 interoperability challenges with based mostly rollups.
It’s not at all times simple to get issues carried out in a flat (non-hierarchical), multi-voice entity like Ethereum, Beck acknowledges. “Ethereum is a decentralized ecosystem. You may’t get everybody on the identical web page .” However a collaboration just like the current one which came about within the UK is a begin.
Cornell Tech convention panelist Hoffman expressed some confidence that Ethereum might pivot and “flip the layer 1 right into a rollup” with processing speeds similar to at present’s L2s.
As famous, Hoffman has criticized the Ethereum Basis for being too insular and tutorial, however he sees indicators that issues could also be altering now, writing lately:
The appointment of co-executive administrators Tomasz Stańczak and Hsiao-Wei Wang marks a brand new period of accountability, course, and inner cohesion.
“I’m feeling optimistic,” added Beck. “Ethereum nonetheless has essentially the most belongings locked for DeFi; essentially the most stablecoins are on Ethereum. BlackRock has a fund that’s deciding on Ethereum.”
Put one other manner, Ethereum remains to be well-positioned to offer the infrastructure for the “community of networks” — i.e., the easily interacting community of multitudinous personal and public blockchains that many hope would be the know-how’s future.
