01Open verification stack
AlwaysVerify
A practical, MIT-licensed foundation for multi-agent systems where claims are tested, evidence is preserved, and agreement is never confused with truth.

Trust should be
witnessed.
NSG Studios builds open, evidence-first systems for a world where software agents act, identities are contested, and “trust me” is no longer enough.

Selected work
Two systems.
One conviction.
High-consequence decisions deserve more than a single source of truth.
02Identity attribution
GeoMFA
A patent-pending identity-attribution system for people and machines: establishing that an actor is who—or what—it claims to be through independent corroboration.

The AlwaysVerify Stack
Agreement is not
verification.
Multiple models can repeat the same error. AlwaysVerify asks a harder question: did an independent witness actually reproduce the result?

Identity is not a secret.
It is a shape.
People and machines should be able to prove they are who—or what—they claim to be.
Humans already establish identity through corroboration: a second signature, another set of eyes, an independent witness. GeoMFA brings that instinct to digital systems—attributing identity through independent confirmation without making any one person, machine, factor, or device sufficient alone.
For people.For machines.
The security thesis
More independent corroboration does more than add checks—it changes the attacker's economics. As corroboration rises, an adversary must compromise, simulate, coerce, or coordinate across a broader set of genuinely independent witnesses. The intended effect is a disproportionate increase in attacker cost, complexity, and exposure—and a nonlinear reduction in the path to successful false attribution.
A security design thesis, not a guaranteed performance curve. Outcomes depend on real independence, implementation, and threat context.“Truth is something witnessed, not something hoarded.”
