Irreversible Transaction

An irreversible transaction is a transfer of value on a blockchain that cannot be undone, modified, or canceled once it has been confirmed and added to a block. Because blockchains are decentralized ledgers, there is no central authority or administrator with the power to reverse entries or revert states.

This property provides finality, which is essential for secure financial settlement. Once a transaction is finalized, the assets are transferred permanently to the recipient address.

This differs significantly from traditional banking, where transactions can often be reversed by institutions. This finality is a core pillar of trustless finance but places the burden of security and accuracy entirely on the user.
