Definition ∞ Controlled mutability refers to the ability to modify data on a blockchain under specific, predefined conditions. This approach allows for intentional, authorized changes to ledger entries, unlike traditional blockchains which are generally immutable. Such modifications are typically governed by smart contracts or multi-signature mechanisms. It represents a deviation from absolute immutability, offering practical flexibility.
Context ∞ The concept of controlled mutability is a key discussion point for enterprise blockchain solutions and regulatory compliance. It addresses concerns about data correction, legal mandates for data deletion, or upgrades to token standards. While enhancing utility for certain applications, it introduces complexities regarding transparency and the trust model of the underlying system.
