✅ Optimistische Rollups (Arbitrum, OP, Base)
- EVM identisch – vorhandene Solidity ohne Änderungen bereitstellen
- Niedrigere Gebühren, insbesondere Base (nach EIP-4844)
- 7-tägige Widerrufsfrist für L1 (zum Überspringen die Schnellbrücke verwenden)
- Größte DeFi-Ökosysteme heute
🔒 ZK-Rollups (zkSync, Starknet)
- Kryptografischer Beweis = stärkere Sicherheitsgarantien
- Schnellere Finalität zu L1 (Stunden vs. Tage)
- Höherer Rechenaufwand = etwas höhere Gebühren
- Wachsende Ökosysteme, die immer noch reifen
TVS figures: L2beat, Oct 2026. Base overtook Arbitrum in value secured during 2026; Optimism and ZK rollups saw sharp TVL declines.
Häufig gestellte Fragen
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.
