Blockchain and centralized databases both play critical roles in modern finance, but their differences matter. Blockchain powers new financial models like tokenization and stablecoins, while centralized systems still dominate high-speed processing in banks. For example, the USDC stablecoin ecosystem grew nearly 90% year-over-year, reaching $61.3 billion by mid-2025 and climbing further since. Meanwhile, traditional systems remain the backbone of daily transactions worldwide. This article unpacks the latest stats and shows how both technologies shape finance.
