Independent security research

Sentinel Zero

A research workflow for turning suspected vulnerabilities into reproducible evidence—or discarding them when the evidence does not hold.

Research position

Do not guess. Prove.

The method begins with a system invariant rather than an automated scanner result. A finding survives only when controlled testing shows a repeatable violation and the report explains both impact and remediation.

This work includes local tooling, audit notes, proof-of-concept tests and remediation reports across web APIs and smart-contract or consensus review exercises.

Validation sequence

From hypothesis to defensible report

01
Define the invariant
State the security property that must always hold—ownership, authorization, accounting, contract state or consensus correctness.
02
Create a controlled mutation
Change one relevant variable at a time and retain a valid baseline for comparison.
03
Test repeatability
Reject findings that cannot be reproduced or whose observed difference does not violate the invariant.
04
Build a proof artifact
Use a focused test, code-level demonstration or structured request comparison that another reviewer can inspect.
05
Write remediation
Explain the missing control and propose a bounded fix without overstating business impact.

Need a security-minded systems review?

Radbit can review authorization boundaries, data handling and workflow risks as part of application architecture. This is scoped separately from certified penetration testing.
