# Immutability `kaal:entity:immutability` **Status.** derived This node is assembled mechanically from the 22 claims that carry the concept tag `immutability`. It is a roster of what the corpus says under this term. It is **not** an adjudicated definition: no single statement here has been ruled canonical, and no first-appearance call has been made. Read the claims and judge for yourself. ## Every claim under this term 22 claims across 16 works, 2017 to 2025. **2017** - [2939127-014](https://wulfkaal.github.io/claims/2939127-014) [mechanism/argued] -- Because a public blockchain is genuinely public and immutable, it increases transparency while simultaneously and significantly reducing transaction costs. > Because the blockchain (at the least the public blockchain) is in fact public and immutable, the technology increases transparency, while at the same time significantly reducing transaction costs.
