🇷🇸 Srbija devs: Add JMBG (Jedinstveni Matični Broj Građana) to the AI identity standard — Soulprint open source (30 min PR)

Every day, AI agents make decisions on our behalf — buying, sending emails, signing documents — and nobody verifies there's a real human behind them.

Soulprint solves this with Zero-Knowledge Proofs: 100% on-device, open source (MIT), free to run. soulprint.digital

🇷🇸 Srbija's JMBG (Jedinstveni Matični Broj Građana) is not in Soulprint yet. You can add it in ~30 minutes with one PR.


What Soulprint does

npx soulprint verify-me       # scan ID + face match — all local
# → SPT token (score 0-100)

# AI agent includes token in every call
# X-Soulprint: eyJ... (score: 84)

# API verifies in 3 lines:
import { requireSoulprint } from "soulprint-mcp";
server.tool("premium", requireSoulprint({ minScore: 80 }), handler);

🇷🇸 Srbija: JMBG (Jedinstveni Matični Broj Građana)

JMBG: 13 digits. DDMMYYYY + region + sequence + check. Mod-11 check digit (weights 7,6,5,4,3,2,7,6,5,4,3,2).


The code — fill in the blanks and open a PR

// packages/verify-local/src/document/countries/RS.ts
import { CountryVerifier, DocumentResult, NumberValidation } from "../verifier.interface";

const RS: CountryVerifier = {
  countryCode:   "RS",
  countryName:   "Srbija",
  documentTypes: ["jmbg"],

  parse(ocrText: string): DocumentResult {
    // JMBG (Jedinstveni Matični Broj Građana) format: 13 digits DDMMYYYYRRNNNC
    const doc_number = ocrText.match(/(\d{13})/)?.[1] ?? "";
    return { valid: !!doc_number, doc_number, country: "RS" };
  },

  validate(docNumber: string): NumberValidation {
    // mod-11 weighted check
    return { valid: validateJMBG(docNumber) };
  },
};

export default RS;

Then add one line in registry.ts:

import RS from "./countries/RS";
// add to registry map: "RS": RS,
Enter fullscreen mode Exit fullscreen mode
