Mandorka

Mandorka is a web-based verification platform that turns real-world work simulations into live, verifiable WorkProof records. Candidates complete job-relevant challenges in a bounded environment, and after each session they receive a versioned proof containing dimensional scores, integrity metadata, and a SHA-256 fingerprint. The platform is positioned as a "WorkProof Network" where work capability becomes verifiable infrastructure rather than another course or certificate shop. The WorkProof protocol is built around strict integrity controls: answers are scored server-side so key mappings never reach the browser, each completed session can only be used once, and the resulting record is machine-readable via JSON for integration into other systems. Candidates receive a portable URL and an embeddable badge, enabling them to own and share their evidence. Employers can verify the live record without creating an account, and can compare candidates on consistent dimensions such as accuracy, judgment, instructions, verification, and communication. Mandorka is a paid B2C service, though limited free runs are available. The WorkProof Sprint costs €19 and provides 15 randomized decisions from three work tracks in a single 45-minute session. A Professional plan adds more Sprint credits for ongoing skill certification. The company also publishes a public standard for scoring and integrity and runs a validation program with research partners to measure whether scores relate to actual job performance. Overall, Mandorka aims to reduce hiring risk by connecting job-relevant simulations with tamper-resistant proof. It targets candidates, freelancers, employers, and researchers, and is designed to support a more accountable and transparent hiring process.

Problem solved

Self-reported skills and polished resumes make it difficult for employers to know if a candidate can actually perform the work. Mandorka solves this by creating verifiable, single-use proof from standardized work simulations, allowing candidates to demonstrate real skills and employers to check claims instantly without relying on unsubstantiated certifications.

Use cases

A candidate completes a WorkProof Sprint to generate evidence for a job application
An employer verifies a candidate's live WorkProof by public URL or JSON record
A freelancer embeds a WorkProof badge on a personal website or portfolio
A hiring team screens candidates before interviews using consistent dimensional scores
A recruiter compares multiple candidates using the same proof standard
A research partner participates in the validation program to study score predictive validity
An affiliate partner promotes WorkProof Sprint to earn referral commissions

Audience

Business Users
Enterprise
Startups
Researchers

Pros

Server-side scoring ensures test answer keys are never exposed to the browser
Single-use sessions prevent a candidate from minting multiple proofs from one run
Portable URLs and embeddable badges make proof easy to share
Employers can verify proofs publicly without an account
Published scoring standard increases transparency and auditability

Cons

Limited number of tracks may not cover every job role
Validity of the assessment signal is still being studied, as stated by the company
Paid plans could be a barrier for some candidates
Requires trust in the platform's integrity of scoring and record-keeping
No evidence yet of wide adoption among major employers
