Why VerifiedState

vs No memory

Agents forget everything between sessions. VerifiedState gives them persistent, queryable, verified facts — across every model, session, and agent in your stack.

vs Raw database

Storing facts is easy. Knowing if they're true is hard. Every VerifiedState assertion ships with a cryptographic receipt proving what evidence supports it, which method was used, and who signed off.

vs Mem0 / basic memory layers

Other memory layers store text. VerifiedState stores structured assertions with confidence scores, temporal validity windows, conflict detection, and signed audit trails that hold up to enterprise scrutiny.


From zero to first verified memory

Four pillars

🔐
Verified
Every fact ships with a signed receipt proving what evidence supported it.
Temporal
Assertions have validity windows and decay automatically. No stale facts.
📜
Governed
JSON policy engine controls who can read, write, verify, or challenge.
🗜
Compressed
Lossless IR + literal sidecar format. Agents read less, retain more.
