## Immutability Vs Security

Immutability refers to the inability to change or delete data once it has been recorded on a blockchain, ensuring a permanent ledger. Security, in this context, refers to the mechanisms that protect the network from unauthorized access, fraud, or malicious manipulation.

While immutability is a core security feature that prevents historical tampering, it creates a unique challenge for smart contract security. If a contract contains a vulnerability or a bug, its immutability prevents developers from simply editing the code to fix the issue.

Therefore, high security in decentralized finance requires rigorous auditing and formal verification before deployment, as there is no undo button. Balancing these concepts is fundamental to designing robust financial derivatives and trading protocols where code is law.
