Blockchains were created with immutability as one of its fundamental principles and to many the thought of introducing limited mutability contradicts the very foundations on which blockchains were first created. While the immutability of blockchains is key to fortifying security and fostering trust, it must be emphasized that immutable blockchains are not faultless and recent exploits in 2023 have raised questions about the possibility of limited mutability.
Immutability only guarantees security when code is invulnerable
Immutability prevents many types of exploits as the inability to modify code or data prevents bad actors or attackers from manipulating a system. However, in situations where upgrades are not possible, challenges may arise, including the risk of encountering delayed updates when necessary modifications are required, or the potential for funds to be left in vulnerable contracts. This is what happened in the August attack against Curve Finance.
