# Implementation Independence
**Entity class:** Computational architecture concept
**Collections:** [[collections/Neurotech|Neurotech]] · [[collections/Consciousness Continuity|Consciousness Continuity]]
## Definition
**Implementation Independence** is the claim that a functional organization can, within relevant constraints, be realized by more than one physical mechanism or substrate.
## Relationships
- It is technically related to [[wiki/Substrate Independence|Substrate Independence]] and philosophically related to [[wiki/Functionalism|Functionalism]].
- [[wiki/Technological Embodiment|Technological Embodiment]] supplies the counterweight: alternative implementations still differ in timing, noise, energy, failure modes, and access geometry.
- [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]] treats cross-substrate implementation as an engineering hypothesis rather than proof of identity preservation.
