Scroll ¹

What is Scroll?

Ethereum but cheaper and faster, using math proofs (zero-knowledge) to guarantee security. The key difference: Scroll prioritizes being identical to Ethereum — your existing code works without changes, unlike competitors that modified things for speed.

Best for: Moving existing Ethereum projects without modifications, DeFi apps that need Ethereum's exact behavior.

Technical: A zkEVM rollup with bytecode-level EVM equivalence and ZK-based finality, built for compatibility with existing Ethereum contracts.

• Security & Data Availability

  • Uses ZK validity proofs to confirm all state transitions before finalization.
  • Publishes calldata to Ethereum using EIP‑4844 blobs; no custom DA layer.
  • Withdrawals are finalized once proofs are verified — no fraud windows.

• Infra & Execution

  • Fully bytecode-equivalent — same opcodes and gas costs as Ethereum.
  • Centralized sequencer; decentralized proving and proposer layers are planned but not yet live.
  • Node stack includes dedicated proving infrastructure.

• Performance

  • Handles high daily tx volumes (~500k/day).
  • Proof submission adds latency — typically a few minutes after batch inclusion.
  • Throughput depends on prover capacity and L1 calldata constraints.

• Use Cases

  • DeFi migrations: Uniswap, Aave, and other majors deployed without code changes
  • NFT platforms: Lower minting costs while keeping OpenSea compatibility
  • DAO tooling: Snapshot, Gnosis Safe work identically to mainnet
  • Developer testing: Same behavior as Ethereum, cheaper to experiment

• Trade-offs

  • Sequencer is not decentralized — risk of transaction censorship or delays.
  • Prover infra is heavy and may bottleneck under load.
  • Finality is fast, but depends on timely proof generation and posting.
  • Ecosystem still early — infra and decentralization not yet fully mature.
