Open-source infrastructure / Digital identity
VC Inspector
A Rust trust-boundary inspector for W3C Verifiable Credentials and DID proof wiring.
A small CLI tool that parses credential JSON, checks trust-relevant structure, optionally compares issuer DID Documents, and outputs pass/warn/fail reports before deeper cryptographic validation.

Code Behind The Surface
Checking the proof boundary
rsThe core move behind the product surface.
let report = inspect_credential(&credential, did_doc);
for check in report.checks {
println!("[{}] {}", check.status, check.message);
}Product Model
tsThe useful answer has to be modeled before the UI can make it obvious.
type ProductSurface = {
input: "Digital identity";
signal: "Where can a standards-based identity flow fail before full cryptographic verificatio";
proof: string[];
};
const surface: ProductSurface = {
input: "Digital identity",
signal: "Credential structure, DID proof wiring, and verification readiness.",
proof: [
"Credential JSON parsing",
"Issuer and subject inspection",
"Proof metadata checks",
"DID Document assertion-method validation"
],
};Hard Part
tsEvery build has a constraint: data quality, workflow shape, trust, speed, or operational risk.
const constraint = {
project: "VC Inspector",
status: "Prototype",
category: "Open-source infrastructure",
hardPart: "The value is clear boundaries. It makes the pre-verification structure explicit so integration teams can see w...",
};

Why This Exists
The point is not to show another screen. It is to show the gap, the build constraint, and the proof of work.
Mission
Where can a standards-based identity flow fail before full cryptographic verification even starts?
Digital credential systems depend on precise trust boundaries: issuer, holder, verifier, proof metadata, controller relationships, assertion methods, expiration, and revocation status. Those details are easy to misunderstand when the flow is hidden behind libraries.
Build
What Had To Work
I built a Rust inspector that validates credential shape, proof metadata, issuer DID wiring, assertion-method control, expiration, and credential status, then prints human and machine-readable reports.
Why It Matters
Pass / warn / fail
Shows credential trust-boundary failures before a team relies on a verifier flow.
Hard Parts
Make The Signal Useful
Make an opaque trust model easier to inspect so builders can understand credential readiness before relying on a verifier flow.
Turn The Work Into A System
I built a Rust inspector that validates credential shape, proof metadata, issuer DID wiring, assertion-method control, expiration, and credential status, then prints human and machine-readable reports.
Prove The Wedge
The value is clear boundaries. It makes the pre-verification structure explicit so integration teams can see what is missing before deeper validation.
Decisions
Next Move
I would add integrations with standards-aware verification libraries, a small UI for credential review, and CI examples for teams integrating credential issuance or verifier flows.

Market Gap
Demand exists, but the answer is missing.
Workflow Drag
The work is still too manual, slow, or scattered.
Product Wedge
A small surface could prove the larger opportunity.
