✅ Acumulaciones optimistas (Arbitrum, OP, Base)
- EVM idéntico: implemente Solidity existente sin cambios
- Tarifas más bajas, especialmente Base (posterior a EIP-4844)
- Período de retiro de 7 días a L1 (use el puente rápido para omitir)
- Los ecosistemas DeFi más grandes de la actualidad
🔒 Paquetes acumulativos de ZK (zkSync, Starknet)
- Prueba criptográfica = mayores garantías de seguridad
- Finalidad más rápida a L1 (horas versus días)
- Mayor costo computacional = tarifas ligeramente más altas
- Ecosistemas en crecimiento, aún madurando
TVS figures: L2beat, Oct 2026. Base overtook Arbitrum in value secured during 2026; Optimism and ZK rollups saw sharp TVL declines.
Preguntas frecuentes
Which Ethereum L2 has the most value secured right now?
As of October 2026, Base leads with roughly $15B in total value secured (per L2beat), having overtaken Arbitrum (~$10.2B) earlier this year. Optimism (~$1.8B) and the ZK rollups zkSync Era (~$0.26B) and Starknet (~$0.36B) trail well behind after steep TVL declines.
What's the real difference between optimistic and ZK rollups?
Optimistic rollups (Arbitrum, Optimism, Base) assume transactions are valid and only run a fraud proof if challenged, which means a ~7-day withdrawal window to Ethereum unless you use a fast bridge. ZK rollups (zkSync Era, Starknet) post a cryptographic validity proof with every batch, so withdrawals finalize in hours instead of days, at the cost of higher proving overhead.
Are L2 fees still much cheaper than Ethereum mainnet?
Yes. Since the EIP-4844 blob fee upgrade, all five networks settle typical transfers for fractions of a cent to a few cents, versus dollars on L1 during congestion. Base and Arbitrum are usually the cheapest; Starknet tends to run slightly higher due to proving costs.
