Ethereum Layer 2s: Powering Institutional Blockchain Adoption

Ethereum L2s offer faster transactions and lower costs, making blockchain viable for enterprise-scale operations.

Optimistic and ZK Rollups provide security and finality, letting institutions customize workflows with high-speed execution.

L2 AppChains let businesses launch dedicated chains while inheriting Ethereum’s robust security and global liquidity.

Ethereum’s Layer 2 (L2) networks are becoming the infrastructure of choice for institutions seeking high-speed, secure, and cost-effective blockchain solutions. According to a report co-written by Etherealize_io, Nethermind, and l2beat, Ethereum L2s are now capable of handling enterprise-scale transactions, making public blockchains viable for large-scale finance. Stablecoins alone settled $27 trillion last year—surpassing Visa’s annual volume—while J.P. Morgan moves over $2 billion daily on Ethereum rails.

Throughput improvements have been dramatic. Ethereum’s mainnet handled 47 transactions per second (TPS) in 2022, but by 2025, L2 networks achieve 1,500 TPS. Currently, 154 L2 networks operate live, providing both speed and security for everyday business operations. L2s extend Ethereum’s core security guarantees while offering enterprises higher throughput, custom execution rules, privacy infrastructure, and significantly lower costs.

Understanding Layer 2 Networks

Unlike sidechains or alternative Layer 1 blockchains, L2s remain extensions of Ethereum. If issues arise, the mainnet acts as a referee, and users can withdraw funds back to L1. Two primary L2 types exist: Optimistic Rollups and ZK Rollups

Optimistic Rollups assume transactions are valid and rely on fraud proofs, with a seven-day withdrawal window. ZK Rollups, in contrast, verify transactions mathematically upfront, providing faster finality in minutes.

Data availability remains crucial. Rollups posting data to Ethereum offer maximum security, while validiums using external data availability require trust in providers. Consequently, high-value regulated use cases benefit most from on-chain data availability, minimizing new trust assumptions.

Leading networks include Base, Arbitrum, and Optimism for optimistic rollups, and Starknet, ZKsync Era, and Linea for ZK rollups. Many now support “AppChains,” allowing institutions to launch dedicated L3s inheriting security from both L2 and Ethereum.
