## Irreversibility of Transactions

The irreversibility of transactions is a defining characteristic of most blockchain-based financial systems, meaning that once a transaction is confirmed and added to the ledger, it cannot be undone. While this provides finality and prevents double-spending, it also means that funds lost to fraud, theft, or human error are typically unrecoverable.

This creates a significant risk profile for users, as there is no central authority to reverse unauthorized transfers. Consequently, security measures must be proactive rather than reactive.

Users and institutions must implement rigorous verification and safety protocols to ensure that every transaction is intended and accurate before it is broadcast to the network.
