Starknet is a Validity-Rollup (also known as ZK-Rollup) Layer 2 network built on Ethereum, designed to empower decentralized applications (dApps) with unparalleled scalability while maintaining Ethereum's renowned security standards. By leveraging advanced cryptographic proofs, Starknet transforms Ethereum's capacity without compromising its core values.
How Starknet Works: Off-Chain Computation with On-Chain Security
At its core, Starknet bundles thousands of transactions into a single STARK proof—a cryptographic verification method processed off-chain. This proof is then submitted to Ethereum as one consolidated transaction, achieving:
- Higher throughput: Processes thousands of transactions per second (TPS).
- Faster finality: Near-instant transaction confirmations.
- Reduced costs: Drastically lowers gas fees compared to Ethereum Mainnet.
- Unmatched security: Inherits Ethereum's decentralization and auditability.

Solving Ethereum's Scalability Trilemma
Blockchain networks face a fundamental challenge: optimizing security, decentralization, and scalability simultaneously—often referred to as the "blockchain trilemma." Ethereum prioritizes security and decentralization, which historically limited its transaction speed and affordability. Starknet addresses this by:
- Off-Chain Execution: Processes transactions outside Ethereum's Mainnet.
- On-Chain Verification: Uses STARK proofs to validate transaction batches with minimal on-chain footprint.
- Seamless Integration: Maintains Ethereum's security while scaling its capacity exponentially.
Key Innovations Behind Starknet's Scalability
- STARK Proofs: Zero-knowledge proofs that verify computations without revealing underlying data.
- Batch Processing: Groups transactions into blocks, reducing on-chain congestion.
- EVM Compatibility: Supports Ethereum's ecosystem tools and smart contracts.
