Why don’t blockchain systems have a “reversal” or refund feature?

[bonk]

Blockchains are designed to be trustless and immutable, meaning transactions are final once confirmed. This prevents fraudsters from altering history, but it also means legitimate users cannot reverse mistakes or thefts.

Introducing a reversal mechanism would require a central authority or consensus override, which would undermine the core security model of most decentralized networks. As a result, companies focus more on prevention, monitoring, and rapid response rather than post-hack recovery.
