Scroll

A bytecode-level zkEVM L2 — the closest mainline to running Ethereum Solidity unchanged with ZK validity proofs.

Scroll prioritises EVM-equivalence (no opcode differences from L1). Stablecoin float is currently smaller than Arbitrum / Base; native USDC available. Validity-proof system is one of the more aggressive ZK production deployments.

ZK rollup (zero-knowledge rollup)An L2 that posts validity proofs to L1, enabling near-instant withdrawals and stronger trust assumptions than optimistic rollups.
L2 (Layer-2)A scaling network that inherits security from an L1 by posting state roots back — rollups, validiums, plasma.
EVM (Ethereum Virtual Machine)The runtime that executes Ethereum smart-contract bytecode — replicated across all EVM-compatible chains.
