Profile

Hi HNI'm one of the authors of Stigmem. Stigmem is an open-source specification and reference node for a shared, federated knowledge substrate for AI agents. The core idea: instead of agents maintaining isolated memory stores, they write typed, provenance-tagged facts into a shared substrate that replicates across nodes via Ed25519-signed peer handshakes.A fact is a seven-tuple: (entity, relation, value, source, timestamp, confidence, scope). Facts are immutable, contradictions surface as first-class conflict records, not silent overwrites. Each fact carries a Hybrid Logical Clock timestamp so ordering is consistent across distributed nodes without a central coordinator.v1.0 is spec-complete

The company sits in the show hn launch segment, where it competes on its core product or service.

The company is listed at the Show HN launch stage of development.
