Abstract is a Layer 2 (L2) blockchain that processes transactions off-chain and batches them for verification on Ethereum, inheriting Ethereum's security while enabling faster, cheaper transactions. As a ZK Rollup built with the ZK Stack, Abstract leverages zero-knowledge proofs to validate transaction batches efficiently.
Understanding Layer 2 Blockchains
What Is a Layer 2 (L2)?
A Layer 2 blockchain scales Ethereum by handling transactions off-chain, reducing congestion and fees. Key features:
- Throughput: Processes thousands of TPS vs. Ethereum’s ~15 TPS.
- Cost: Lowers gas fees by batching transactions.
- Security: Maintains decentralization via Ethereum settlement.

Why L2s Matter
Ethereum’s limitations—high fees and slow speeds—make L2s critical for:
- DeFi: Affordable trading and lending.
- NFTs: Cheaper minting and transfers.
- Gaming: Seamless in-game transactions.
ZK Rollups: Abstract’s Core Technology
How ZK Rollups Work
- Batching: Groups transactions into a single proof.
- Validity Proofs: Uses zero-knowledge proofs to verify correctness without re-executing on Ethereum.
- Efficiency: Reduces data stored on-chain by ~90%.

FAQ
Q: How does Abstract ensure security?
A: By anchoring batches to Ethereum and validating them with zero-knowledge proofs.
Q: Can I migrate dApps from Ethereum to Abstract?
A: Yes—Abstract supports EVM compatibility for seamless migration.
Q: What’s the difference between ZK and Optimistic Rollups?
A: ZK Rollups use cryptographic proofs for instant finality; Optimistic Rollups rely on fraud detection.
