Can Ethereum Keep Up with the Growing Layer 2 (L2) Demand?

Ethereum has long been the backbone of decentralized finance (DeFi), gaming, and other Web3 applications. However, as adoption surges and transaction volumes climb, especially on Layer 2 networks, the big question looms: Is Ethereum ready to handle the load?

The State of Ethereum L2s in 2024

Layer 2 networks like Base (by Coinbase) and Optimism have become crucial for scaling Ethereum. These networks process transactions offchain before bundling them and settling on Ethereum’s main chain.

This design keeps costs low and transaction speeds high. In August 2024, Ethereum’s Layer 2 ecosystems processed an average of 12.4 million transactions daily, a staggering figure that shows the growing reliance on L2s. Base alone saw usage grow by 300% this year, fueled by meme coins and other trendy projects.

While these numbers highlight the success of L2s, they also signal growing pressure on Ethereum’s infrastructure. If Ethereum’s base layer doesn’t evolve to support this demand, L2s could face bottlenecks, leading to congestion, higher fees, and slower transactions — the very problems they were designed to solve.

How Ethereum Plans to Scale

Ethereum developers are actively working on upgrades to ensure their infrastructure can meet rising demands. Two major innovations in the pipeline are Danksharding and PeerDAS (Peer Data Availability Sampling).

Danksharding:

This upgrade restructures Ethereum’s data handling by dividing it into smaller units called “shards.”
Shards can be processed in parallel, greatly increasing Ethereum’s capacity to handle data and benefiting L2s that depend on Ethereum for security and data availability.

PeerDAS:

PeerDAS allows validators to confirm the availability of data without downloading it all, using probabilistic sampling methods.
This reduces the hardware requirements for securing the network and boosts scalability while maintaining decentralization.
Together, these upgrades promise to provide the additional blockspace L2s need for long-term growth. However, they’re still under development, with PeerDAS notably delayed.

Immediate Solutions and Challenges

With major upgrades like Danksharding and PeerDAS still on the horizon, Ethereum needs interim solutions. One idea, supported by Ethereum co-founder Vitalik Buterin, is to increase the blob space—the amount of data L2s can upload to Ethereum’s base layer.

A 33% increase in blob space could offer temporary relief by accommodating more L2 transactions. However, this isn’t a permanent fix, as demand is growing faster than incremental adjustments can handle.

Risks of Delay

If scaling upgrades are delayed too long, Ethereum faces several risks:

Congestion and Higher Fees: L2s could struggle to meet user demands, undermining their value proposition.

Competition from Other Chains: Faster but less secure networks might attract developers and users, leading to Ethereum losing its dominant position.

Stalling Adoption: Without scalable solutions, the growing wave of Web3 adoption could slow, hindering the ecosystem’s potential.

The Future

For Ethereum to continue as the foundation of Web3, timely implementation of upgrades like Danksharding and PeerDAS is essential. The network’s developers are racing against rising demand, but delays could mean ceding ground to competitors.

While short-term solutions like increasing blob space can help, they are only a stopgap. The long-term success of Ethereum as the ultimate blockchain for global payments, DeFi, and gaming hinges on these innovative upgrades arriving before demand outpaces the network’s capacity.

Ethereum’s future looks promising, but the race to scale is far from over. If the ecosystem can rise to the challenge, it will solidify its role as the cornerstone of decentralized innovation.
