Optimistic vs ZK Rollups — Why ZK Withdraws in Hours Not Days (2026)

Описание: Optimistic rollups withdraw in days. ZK in hours. Here's the proof system that decides — and why your first L2 choice depends on it more than fees ever will.

WHAT YOU'LL LEARN:
🔹 Two ways to convince Ethereum: fraud proofs vs validity proofs — explained without the maths jargon
🔹 Why the seven-day window isn't a fee — it's a HOLDING period that costs traders real money
🔹 Where BoLD changed optimistic rollups (Arbitrum, Feb 2025) — permissionless challenges, large assertion bonds
🔹 Boojum and S-two — the ZK provers that brought cryptography down to consumer GPUs
🔹 Why "good enough for now" (optimistic) and "right forever" (ZK) are both correct answers — to different questions
