Bitchat Geohash Code List: Hello guy’s in this article we all Learn what geohashing is, how it works, why geohashes are useful for proximity and search, edge cases to know, and get a copy‑ready geohash code list table.

What is a geohash? :

In Bitchat, geohash is a way to convert the real-world locations into the short and unique codes. Each code represents a certain area on the world map. this could be a few streets, a town or even an entire region. These codes act as chat rooms where people in or near that area can connect through Nostr relays.

A geohash is a compact alphanumeric string that encodes latitude and longitude into a hierarchical grid cell on the Earth’s surface, enabling fast, prefix-friendly spatial indexing and lookup. Nearby points often share longer common prefixes, which makes string prefix searches a practical first step for proximity filtering in databases and caches. Each additional character subdivides the grid into 32 finer cells, increasing precision.

How It Works:

1. Location into Code
   Your GPS position is converted into a geohash code. Depending on the size of the grid, this can link you to a small neighborhood group or a larger regional one.
2. Area-Based Chat Rooms
   Each geohash is tied to a specific chat channel. When you’re inside that location, you can join and chat with others nearby.
3. No Central Server
   Messages are shared across multiple Nostr relays, so communication stays decentralized and doesn’t depend on a single authority.
4. Privacy First
   Bitchat assigns a fresh, anonymous ID for every geohash channel. This way, you can join local chats without revealing your exact location.

How geohashing works for Bitchat Channels Join by Geohash:

Interleave bits from longitude and latitude after iteratively halving their ranges; this yields a bitstream that is then grouped into 5-bit chunks. Convert 5‑bit chunks to Base‑32 using the geohash alphabet [0123456789], [bcdefghjkmnpqrstuvwxyz] letters a, i, l, o are leave to avoid confusion.

Each extra character “zooms in” by sub divided in the parent cell into 32 sub cells, so precision increases with length.

1. Practical benefits : Fast shortlist for proximity: Use prefix matching on 5–6 characters to narrow candidates, then compute exact distances (e.g., Haversine) for accuracy.
2. Simple partitioning: Geohash prefixes can act as partition keys or primary sort keys in key‑value stores and search indices.
3. Easy bucketing: Consistent tiles for aggregation, heatmaps, and map zooms.
4. Known limitations and edge cases
5. Boundary artifacts: Points that are physically close but separated by a large geohash boundary may not share a prefix. Always follow a prefix filter with precise distance checks and consider adding the eight neighboring geohashes of the target cell for robust coverage.
6. Latitude effects: Cell shapes distort with latitude; widths shrink toward the poles. Treat geohash cells as approximations, not exact polygons, and don’t equate equal prefix length with a fixed meter accuracy everywhere.
7. Recommended usage pattern: Choose a coarse precision (often 5–6 chars) to filter by prefix and neighbors.

Decode candidate geohashes or use stored coordinates to compute exact distances. Apply final sort/radius filters to produce accurate results
