Since pivoting to a layer 2-centric approach, the Ethereum (ETH) ecosystem has relied heavily on L2 solutions to scale. However, these solutions are struggling to compete effectively, especially under pressure from alternatives like Solana (SOL). During the recent meme coin craze, Solana attracted much of the activity due to its advantages: low fees, high transaction speed, and user-friendliness.

To understand the challenges, it’s essential to examine why L2 solutions have not demonstrated the scalability and cost advantages that were widely anticipated.

Why meme projects favor Solana over Ethereum L2s

Meme projects have significantly contributed to the recent surge in market activity. These projects favor Solana for several reasons beyond user-friendliness:

• Low fees: Solana’s low transaction costs make it ideal for fee-sensitive applications like memecoins.
• High speed: Solana’s multithreaded architecture enables high throughput, ensuring seamless user experiences.
• Better developer experience: Solana’s tools and ecosystem are optimized for ease of use, attracting developers and projects.

Why is scalability important?

Scalability is fundamentally measured by the number of transactions a blockchain can process. A highly scalable blockchain can handle more TXs while offering lower fees, making it crucial for widespread adoption and maintaining a seamless user experience.

This is especially important for grassroots projects like meme coins, many of which are short-lived and highly fee-sensitive. Without scalability, these projects cannot thrive, and users will migrate to platforms that offer better efficiency and cost-effectiveness.

Why Ethereum L2s aren’t up to the challenge

Architectural limitations of Ethereum. Ethereum has long faced scalability issues, and L2 rollups are its primary solution to these problems. L2s operate as independent blockchains that process transactions off-chain while posting transaction results and proofs back to Ethereum’s mainnet. They inherit Ethereum’s security, making them a promising scaling approach.

However, Ethereum’s original design poses inherent challenges. Ethereum’s founder, Vitalik Buterin, has admitted that “Ethereum was never designed for scalability.” One of the key limitations is the lack of multithreading in the Ethereum Virtual Machine. The EVM, which processes transactions, is strictly single-threaded, meaning it can handle only one transaction at a time. In contrast, Solana’s multithreaded architecture allows it to process multiple transactions simultaneously, significantly increasing throughput.

L2s inheriting Ethereum’s limitations. Virtually all L2 solutions inherit Ethereum’s single-threaded EVM design, which results in low efficiency. For instance, Arbitrum: With a targeted gas limit of 7 million per second and each coin transfer costing 21,000 gas, Arbitrum can handle about 333 simple transactions per second. More complex smart contract calls consume even more gas, significantly reducing capacity. Optimism: With a gas limit of 5 million per block and a block time of 2 seconds, Optimism can handle only about 119 simple transfers per second. Gas-intensive operations further reduce this capacity.

Unstable fees. Another major issue with Ethereum and its L2 solutions is unstable fees during periods of high network activity. For applications relying on low and stable fees, this is a critical drawback. Projects like meme coins are especially fee-sensitive, making Ethereum-based L2s less attractive.

Lack of interoperability between L2s. The scalability argument for having multiple L2s only holds if contracts on different L2s can interact freely. However, rollups are essentially independent blockchains, and accessing data from one rollup to another is as challenging as cross-chain communication. This lack of interoperability significantly limits the potential of L2 scalability.

What can L2s do to further scale?

Embed features to enhance interoperability. Ethereum L1 needs to do more to support interoperability among L2s. For example, the recent ERC-7786: Cross-Chain Messaging Gateway is a step in the right direction. While it doesn’t fully resolve the interoperability issue, it simplifies communication between L2s and L1, laying the groundwork for further improvements.

Architectural updates: Diverge from the existing L1 design. To compete with multithreaded blockchains like Solana, L2s must break free from Ethereum’s single-threaded EVM design and adopt parallel execution. This may require a complete overhaul of the EVM, but the potential scalability gains make it a worthwhile endeavor.

Future milestones

Ethereum’s L2 solutions face significant challenges in delivering the scalability and cost-effectiveness that applications like meme coins demand. To stay competitive, the ecosystem must address fundamental architectural limitations, enhance interoperability, and embrace innovations in blockchain design. Only by doing so can Ethereum L2s achieve the scalability needed to support widespread adoption and fend off competition from emerging blockchains like Solana.

Three coins have risen to the top of the leaderboard: The Dogeson, a playful nod to Elon Musk, his son and Dogecoin; Shiro Neko, a cat-themed token tied to gaming and NFTs; and Orbit, a space-inspired coin.

These tokens topped the gainers’ charts on Saturday night. Here’s a closer look at each.

Dogeson

The Dogeson (DOGESON), a Doge-inspired coin named after an edited photo Elon Musk posted of himself and his son, X Æ A-12, is up more than 90% at last check Saturday.

With a market cap reaching $146.6 million, the token is built on the Ethereum blockchain and has garnered attention for its narrative of a “space-bound Doge” — meshing humor with a decentralized finance (DeFi) theme​.

Details about The Dogeson’s founding team or developers were not immediately clear.

Shiro Neko

Shiro Neko (SHIRO) is a new cryptocurrency project that blends blockchain technology with play-to-earn (P2E) gaming.

Its ecosystem is built around a native token that can be used for in-game purchases, staking, and governance.

It’s up over 83% at last check, with a market cap of about $441 million.

The project emphasizes a community-driven approach, immersive gaming experiences, and collectible in-game assets, including NFTs. It aims to attract both gamers and crypto enthusiasts through competitive challenges and real-world rewards​

Shiro Neko is also building on Shibarium, the Layer 2 blockchain for the Shiba Inu ecosystem, further anchoring itself in a popular crypto community. Additionally, the project is venturing into entertainment by launching an animated series featuring “Shiro” the cat.

The token recently had its Initial Exchange Offering (IEO) on Gate.io, with 88 billion tokens available for sale, representing 0.01% of its total supply of 1 quadrillion tokens.

This reflects a focus on early adoption and community-building in the crypto-gaming landscape​.

Orbit

Orbit (ORBIT) was up 77.6% at last check Saturday, with a market cap of roughly $44 million.

Built on the Blast Chain, the native utility token of the Orbit Protocol serves multiple purposes including facilitating governance, incentivizing participants, and enabling staking for rewards.

The protocol also boasts a Total Value Locked (TVL) of over $6.4 million and a fixed total supply of 100 million.

As of now, ORBIT’s market performance shows significant price fluctuations, with a 24-hour range of $0.02543 and $0.06379.

BEAMING OVER THE BEAM CHAIN: What’s good for the L1 is good for the L2s. That’s the assessment the teams behind zkSync and Polygon, two of the leading layer-2 networks running on top of Ethereum, gave of Justin Drake’s proposal to overhaul the $400 billion blockchain, dismissing suggestions it would make their auxiliary networks redundant. “That’s really a misconception,” said Alex Gluchowski, the CEO of Matter Labs, the developer firm behind zkSync. “The changes that Justin announced are focused on the consensus layer, not on the execution layer. It’s not going to affect the execution layer.” In addition to incorporating ZK, Drake’s proposal seeks to shorten block times, which could cut transaction costs for L2s settling on Ethereum. Drake also said he wants to introduce single-slot finality, meaning blocks with transaction data could be finalized immediately, and that information would become permanent right away. “All of those things are great because we depend on Ethereum as the global settlement layer,” Gluchowski said. Brendan Farmer, a co-founder at Polygon, also told CoinDesk he doesn’t think the Beam Chain would obsolesce layer-2s. Instead, he said, the upgrade would “make rollups work better.” However, others in the crypto community were underwhelmed by the whole plan, lamenting in particular that Drake’s five-year timeline wasn’t ambitious enough, leaving ample room for centrally-developed chains like Solana to eat Ethereum’s lunch.” Read more

SUI OUTAGE: Sui Network (SUI), a relatively new blockchain, experienced an unexpected two-hour outage on Thursday. The downtime was caused by a bug in its transaction scheduling logic, which led to its validator network crashing. The issue was resolved, the network said. Blockchain outages can take place for a plethora of reasons, ranging from a 51% attack to technical errors. A common error is that of nodes – or individual entities that process transactions – being unable to sync with each other, causing the blockchain to go offline. Software bugs may be another error vector, where outdated code can render the network’s processes inoperable. Read more

STAKING ON STARKNET: Starknet has become the first major rollup blockchain running on top of Ethereum to let users earn money by staking their tokens and validating transactions. (Metis was the first layer-2 to do so but is far smaller and is an “optimium,” a different kind of L2.) Now, anyone who has at least 20,000 STRK tokens (roughly $12,000 at recent prices) can pledge the asset as collateral and earn rewards for validating transactions. Users with less than 20,000 STRK can delegate their tokens to validators to stake on their behalf. (Validators that behave maliciously or neglect their duties stand to forfeit staked tokens.) Validators and delegators that want to withdraw staked tokens must wait 21 days to receive them as well as any rewards earned from staking. Implementing staking on Starknet is part of a multiphase plan. During this first phase, StarkWare, the company developing Starknet will study staking habits on the network, and from there will assess whether and how its validators can be given the additional responsibilities of creating and “attesting,” or confirming, blocks in the protocol.

AVALANCHE’S BIG UPGRADE: Avalanche, the eighth-largest blockchain by total value locked (TVL), is moving ahead with a major technical makeover. The Avalanche9000 upgrade went live in a test network environment Monday, bringing the changes one step closer to the main network. Avalanche9000 will be the largest upgrade that Avalanche has seen. It is designed to cut the costs of sending transactions, operating validators and building apps on the network, whose native token (AVAX) is the 11th-largest cryptocurrency, with a $16 billion market cap. The foundation is trying to attract developers to Avalanche and encourage users to create customized blockchains using its technology, known as subnets. Somewhat confusingly, subnets are now officially referred to in the Avalanche community as “L1s,” even though they are roughly analogous to the layer-2, or L2, networks that augment Ethereum and other blockchains. (Avalanche’s “primary network,” the equivalent of a layer-1 in other ecosystems, is considered a subnet.) The team is hoping to bring Avalanche9000 to mainnet by yearend. Among other changes, 9000 would allow for a new type of validator with which anyone can launch their own subnets. Read more

ONE-WAY TICKET: BitcoinOS, a smart contract project led by crypto O.G. Edan Yago, has executed what it bills as the first trustless bridge transaction for any blockchain. Using zero-knowledge cryptography, a nominal amount of bitcoin (0.0002 BTC, about $19 and change) was locked up on the main blockchain’s testnet, and a proof was generated minting tokens on the testnet for Merlin Chain, a layer-2 network. No oracle or custodian was involved, according to BitcoinOS. For now, however, Merlin Chain is like the Hotel California or a roach motel for the bridged BTC. “This is one half of the bridge showing the ability to bridge assets from Bitcoin to an EVM,” BitcoinOS said in a press release. “Once the other half of the bridge is completed, Merlin Chain users can settle their Bitcoin-pegged assets back to the mainchain by proving that the tokens were burned.”

Ethereum’s Blob Mob

Usage of binary large objects, or blobs, has surged on the Ethereum network, signaling that more users are embracing layer-2 scaling tech for faster and more affordable transactions.

This year, Ethereum’s Dencun upgrade introduced blobs, which allow large chunks of data to be temporarily attached to transactions, and later deleted after the data is verified. (You can think of a blob as a sidecar that rides along with a motorcycle for a time but eventually gets detached and discarded.) Layer-2 protocols such as BASE, Arbitrum, and Optimism use blobs to bundle transactions together, process them off-chain and then post them to the Ethereum main chain for verification without permanently gumming up the works.

The number of blobs posted to the network consistently averaged more than 21,000 this month, matching the record activity seen in March, according to pseudonymous data analyst Hildobby’s Dune Analytics dashboard.

Posting blobs costs a fee, which fluctuates depending on network conditions. The fees are paid in Ethereum’s native token ether, and are burned just like regular transaction fees, taking supply of ETH off the market, a positive for the coin’s price.

In this way, blobs mitigate the much-discussed cannibalization of the main chain by L2.

The blob base submission fee spiked as high as $80 on Monday, the highest since March, and the average number of blobs posted in each Ethereum block rose to 4.3. More importantly, blob fees have burned over 214 ETH worth $723,000 over the last seven days, the sixth largest source of fee burns on the network over that period, according to data from ultrasound.money.
