What is Payment Fraud?
Payment fraud encompasses unauthorized or deceptive transactions designed to steal funds — a major problem in traditional finance that blockchain's cryptographic authentication and finality model addresses differently.
WHY IT MATTERS
Traditional payment fraud costs over $30B annually. Card-not-present fraud, identity theft, and unauthorized transactions are rampant because traditional payment authentication is relatively weak.
Crypto's cryptographic authentication (private key signing) makes unauthorized transactions much harder — you can't initiate a transaction without the key. But crypto introduces new fraud vectors: phishing, social engineering, and smart contract exploits.
The trade-off: crypto eliminates many traditional fraud types but introduces new ones. The irreversibility that prevents chargebacks also means fraud victims have no recourse for on-chain transactions.
