Immutable Smart Contract Logic
Immutable smart contract logic refers to code that cannot be altered once it has been deployed to the blockchain. This is the ultimate form of security, as it removes the risk of an administrator or attacker changing the rules of the game.
In derivatives, this means that the margin requirements, liquidation logic, and settlement rules are fixed and transparent. However, it also means that any bugs discovered after deployment cannot be fixed.
This requires rigorous auditing and testing before launch. The trend toward immutability is a response to the risks associated with upgradable contracts, which often rely on trusted multi-sig signers.
It represents a commitment to trustless, permanent financial infrastructure.
