Why can no one reverse a transaction if I make a mistake?

Malairte transactions are final by design, and that finality is a feature, not a flaw. Because there is no central company controlling the network, there is also no central authority with the power to reverse, freeze, or undo a payment. Once a transaction is confirmed on the blockchain, it is permanently recorded across thousands of independent computers. This is what makes the system trustworthy and resistant to censorship — nobody can quietly claw back your coins either. The trade-off is that responsibility sits with you. If you send coins to the wrong address, there is no helpline to call. That is exactly why careful habits matter: always copy and paste addresses, verify the first and last characters, and send a small test amount first when paying someone new.
