🚀 Linea (ZK-Rollup) vs. Optimism/Arbitrum (Optimistic Rollup)
🔷️Linea (ZK-Rollup)
🔸️Verification Method: Uses Validity Proofs (Zero-Knowledge Proofs).
🔸️Security Assumption: Transactions are invalid until proven valid.
🔸️Withdrawal Time (L2 \to L1): Near-Instant. The proof is verified cryptographically.
🔸️Security Model: Purely cryptographic. Fraud is considered mathematically impossible.
🔸️Developer Complexity: Historically higher due to zkEVM complexity.
🔶️Optimism/Arbitrum (Optimistic Rollup)
🔹️Verification Method: Uses Fraud Proofs (Challenge Period).
🔹️Security Assumption: Transactions are valid until proven otherwise.
🔹️Withdrawal Time (L2 \to L1): Long Delay (Typically 7 days for the challenge period).
🔹️Security Model: Relies on economic incentives (stakers) to challenge fraud.
🔹️Developer Complexity: Lower, as it's nearly 100% EVM-compatible from the start.
