Arbitrum vs Plasma

Arbitrum One and Nova are optimistic rollups using Nitro fraud proofs that compress transactions into calldata submitted to Ethereum. The Orbit toolkit lets projects deploy their own Arbitrum Orbit chains with configurable permissions. ARB token governance manages the 3 000‑plus validator whitelist and a 1 billion‑dollar ecosystem grant fund.

Plasma is a high-performance layer 1 blockchain purpose-built for stablecoins, delivering near-instant, fee-free payments with institutional-grade security. Its infrastructure supports thousands of transactions per second, sub-second block times, and global interoperability across 100+ currencies and payment methods. Backed by industry leaders like Bitfinex and Founders Fund, Plasma aims to power the next phase of stablecoin adoption with scalable, decentralized rails for the digital dollar economy.
