Frequently Asked Questions
Was ist der Unterschied zwischen Optimistic und ZK Rollups?
Optimistic rollups assume transactions are valid and use fraud proofs, offering full EVM compatibility. ZK rollups use validity proofs for faster finality and stronger security but are more complex.
Are Layer 2s cheaper than Ethereum mainnet?
Yes, L2s typically cost a fraction of mainnet gas for everyday transactions, which is why most DeFi activity now happens on Layer 2.
Which L2 is best for DeFi?
The answer depends on the assets and protocols you use. Arbitrum hosts the largest DeFi ecosystem, while Base and others offer low costs and specific integrations.
