# 5.3 ZK-ID (The One-Pass)

The Accessth ZK-ID is a portable identity standard. Currently, on-chain history is public. If you interact with a sensitive dApp, that interaction is permanently linked to your financial history.

ZK-ID allows for selective disclosure.

* You can prove you are a unique human (Sybil resistance).
* You can prove you are an accredited investor (holding >$1M assets).
* You can prove you are a long-term holder. ...all without revealing your address or specific balance.

This creates a reputation layer for Ethereum that respects privacy, essential for institutional adoption.
