payment finality

Blockchain payment finality means the transaction is irreversible once confirmed, unlike chargebacks in card networks.区块链支付最终性意味着交易一旦确认便不可撤销，这与卡片网络中的拒付截然不同。

Payment finality is critical for merchants—knowing a payment cannot be reversed removes fraud risk from transactions.支付最终性对商户至关重要——知道支付无法被撤销消除了交易中的欺诈风险。
