What is Payment Dispute?
A payment dispute in crypto is a disagreement between parties about whether a payment obligation has been satisfied — handled through smart contract escrow, arbitration protocols, or off-chain resolution since blockchain transactions can't be reversed.
WHY IT MATTERS
Without chargebacks, crypto needs alternative dispute resolution. Smart contract escrow (hold funds until conditions verified), multi-sig release (both parties must agree), and decentralized arbitration (Kleros, Aragon Court) provide mechanisms.
The challenge: disputes often involve off-chain facts (was the service delivered? was the product satisfactory?) that smart contracts can't verify directly. Oracle-based verification and human arbitration bridge this gap.
Well-designed payment flows minimize disputes through: clear terms encoded in contracts, milestone-based releases, and mutual confirmation before final settlement.
