xrayGraphDB holds and traverses the entire Friendster social graph, 1.8 billion friendships, on one server. A breadth-first walk from one person reaches every one of 65,608,366 people, and the last of them is 22 hops away. Every property value, string, WAL entry and key is encrypted at rest with AES-256-GCM.
| hop | newly reached (log scale) | people | covered | time |
|---|
A figure appears here only when its run archive recomputes it from the raw samples. Courtroom-clean latency and throughput results are coming soon, measured head-to-head on equal hardware. (Hint: we think you’ll like them.)

Benchmarks run in this mode. There is no faster, unencrypted mode to quote.
Protocol frozen
Hashed and timestamped before the first sample.
Binary pinned
The running engine is checked against the build under test.
Samples signed
Raw samples go into a signed, hash-chained ledger.
Recomputed
Every published figure is recomputed from those samples.
The Tracing demo joins federal campaign-finance filings, nonprofit tax returns and the ICIJ Offshore Leaks into one graph, then follows the connections from any starting point.
Each source arrives as its own bulk files. xrayGraphDB stores every filing as nodes and edges, records which file and snapshot each fact came from, and links entities across sources only where their filings share an exact identifier or address.
A trace starts from one entity and expands outward hop by hop. At every hop the engine reports how many entities it reached and how many connections it explored, and the page shows how long that live query took.
Demonstration only. The demo shows relationships recorded in public filings; nothing in it indicates or suggests wrongdoing by any person or organization. Individual donors appear only under serial pseudonyms. The live trace returns when the demo comes back online; until then this section describes it.
