Unlinkability
Definition
Unlinkability is a privacy property ensuring that different actions or transactions cannot be connected to the same entity. In cryptocurrency, unlinkability prevents observers from determining that multiple addresses or transactions belong to the same user.
Technical Explanation
Blockchain transactions create links when inputs and outputs can be traced. Techniques like stealth addresses, ring signatures, and mixing protocols break these links. With perfect unlinkability, even if individual transactions are visible, connecting them to form user profiles becomes impossible.
Unlinkability must persist against all adversaries, including those with quantum computers. If quantum attacks could break the privacy cryptography, transaction links could be revealed. Post-quantum privacy schemes maintain unlinkability even against quantum-equipped analysts.
SynX Relevance
SynX implements unlinkability features that remain secure against quantum analysis. Optional stealth addresses generate unique one-time addresses for each transaction, preventing address reuse from creating links. Privacy features use quantum-resistant constructions throughout.
Frequently Asked Questions
- Can blockchain analysts link my SynX transactions?
- With privacy features enabled, linking becomes computationally infeasible.
- Does unlinkability hide transaction amounts?
- Unlinkability specifically prevents address linking; amount privacy requires additional techniques.
- Is unlinkability always enabled?
- Privacy features are optional—you choose your desired privacy level per transaction.
