Layer-2 Scaling Challenges in 2025
The second quarter of 2025 has exposed the limitations of blockchain scaling. As investments pour into rollups and sidechains,the layer-2 (L2) model faces increasing scrutiny. initially, L2s promised to enhance ethereum’s scalability. However, they’ve introduced new issues, such as high costs, delays, and fragmented user experiences.
L2s handle transaction sequencing and state computation. They use Optimistic or ZK Rollups to settle on the main layer. Optimistic Rollups offer long finality times, while ZK Rollups are computationally expensive. Both have trade-offs.
Future solutions may involve separating computation from verification. Centralized supercomputers could handle computations, while decentralized networks verify them in parallel. This approach could scale blockchains without compromising security.
The traditional “total order” blockchain model is becoming outdated. Shifting to local, account-based ordering could unlock massive parallelism. This change could resolve the “L2 compromise” and build a scalable web3 foundation.
New projects,like stablecoin payments,are questioning the L2 paradigm. They wonder if L2s are truly secure and if their sequencers are single points of failure. Fragmentation seems inevitable in web3.
Are we building on a solid foundation or a house of cards? L2s must address these questions.If Ethereum’s base layer were inherently fast, cheap, and scalable, the L2 ecosystem would be redundant. L2s are a workaround for L1 constraints, creating technical debt for users and developers.
To find answers, we need to deconstruct L2s. their structure determines their function. L2s perform two key tasks: sequencing transactions and computing new states. Sequencing involves ordering and batching transactions. State computation updates balances and must be settled on the main layer for security.
Efficiency and Scalability in Layer 2 Solutions
Layer 2 (L2) solutions can considerably boost blockchain efficiency. Once transactions are sequenced, computing the next state becomes a purely computational task. This can be handled by a single supercomputer, optimized for speed. This supercomputer can even be shared among different L2s.
After the new state is claimed,verification becomes a separate process. A network of verifiers can work in parallel to check the claim. This is similar to Ethereum’s stateless clients and high-performance systems like MegaETH.
Parallel verification is infinitely scalable. No matter how fast L2s produce claims, the verification network can always keep up by adding more verifiers.This is the theoretical optimum: using decentralization effectively for verification, not computation.
After sequencing and verification,the L2’s job is nearly complete. The final step is to publish the verified state to a decentralized network, the Layer 1 (L1), for ultimate settlement and security.
However, blockchains are not ideal settlement layers for L2s. The main computational work is done off-chain, yet L2s must pay a premium to finalize on an L1. This creates congestion and high costs. L1s also have inherent finality delays.
For ZK Rollups, this delay is minutes. For Optimistic Rollups, it’s a week-long challenge period. This “total order” paradigm is costly and overkill for L2 settlement.
It’s time to move on from the “total order” myth. The future is local, account-based ordering. Onyl transactions interacting with the same account need to be ordered, unlocking massive parallelism and true scalability.
Global ordering is naive and simplistic. The distributed systems scientific domain has already transitioned to a strong eventual consistency model that unleashes parallelism and concurrency. It’s time for the web3 industry to follow forward-looking scientific progress.
