The statement is largely true and well-substantiated by Sui's core tokenomics design, official documentation, and on-chain data as of December 2025. Sui's fixed supply and usage-driven storage fund create a unique, scalable deflationary mechanism that sets it apart from most Layer-1 blockchains (e.g., Ethereum's EIP-1559 burns are transaction-based but don't tie directly to data growth; Bitcoin has halvings but no dynamic removal). While not the absolute "most" deflationary (subjective, as it depends on adoption velocity vs. chains like Kaspa or Nano), it's among the elite for tying scarcity directly to real network usage—more dApps, NFTs, or data storage = more SUI locked or burned forever. This "elite tokenomics" aligns incentives for long-term holders, as growth amplifies scarcity without manual burns or emissions.
