What is GyID?
The Identity Layer for Geoyuan
GyID (Geoyuan Identity) is a decentralized identity system that generates unique, permanent IDs from multiple dimensions: hardware fingerprint, geographic location, timestamp, and avatar hash.
How It Works
Collect
Gather hardware fingerprint, GPS/WiFi/IP location, and timestamp in parallel.
Hash
Combine inputs through a multi-dimensional cryptographic hash algorithm.
Encode
Encode the result in Base58 to produce a human-readable GyID string.
Anchor
Optionally anchor the identity hash to Polygon or Aptos blockchain.
Permanent
Once generated, a GyID is immutable and cannot be deleted.
Offline-First
Works without internet. GPS and hardware fingerprint alone can generate a valid ID.
Multi-Chain
Supports Polygon PoS (EVM) and Aptos (Move) for on-chain anchoring.
H3 Spatial
Built-in H3 hexagonal grid encoding for spatial identity and NFT geofencing.
H3 Spatial Indexing
GyID uses Uber's open-source H3 hexagonal geospatial indexing system to partition the Earth's surface into hierarchical hexagonal cells. Each cell has a unique identifier for location encoding and spatial indexing.
