Arbitrum was literally designed from day one with privacy in mind - not as an afterthought, not as an add-on, but baked directly into its architecture. Straight from the original Princeton research paper: ➡️ Smart contracts execute off-chain inside a private VM ➡️ Only disputes get shown on-chain ➡️ Honest parties can advance state privately without revealing internal logic ➡️ Verifiers only check signatures - not full execution ➡️ Massive scalability + native privacy That means: 🔒 Sensitive contract logic stays private 💨 Heavy computation happens off-chain 🛡️ On-chain only sees the minimal data needed to prove correctness ⚡ And you still get Ethereum-level security guarantees Arbitrum isn’t just fast. It isn’t just cheap. It isn’t just leading L2 adoption. It’s one of the only rollups originally engineered to deliver scalability and privacy together without sacrificing trustlessness.
