PsicoStacks

Introduction to PsicoStacks

A decentralized platform for creating and verifying psychometric credentials on the blockchain.

What is PsicoStacks?

PsicoStacks is a blockchain-based platform that allows candidates to create verifiable, portable psychometric credentials as Soulbound Tokens (SBTs) on the Stacks blockchain. These credentials can be shared with employers who can verify their authenticity by paying a small fee, ensuring trust while preserving privacy.

The platform leverages AI (Mistral) for intelligent data extraction and Stacks blockchain for immutable, Bitcoin-secured credential storage.

Key Features

🔗 Blockchain-Verified

Credentials are stored as non-transferable SBTs on Stacks, inheriting Bitcoin's security.

🤖 AI-Powered

Mistral AI extracts and analyzes psychometric data, generating structured summaries.

🔒 Privacy-First

Full reports are encrypted (AES-256-GCM) and only accessible via time-limited tokens.

💰 Pay-to-Verify

Employers pay 10 STX (~$3) to access full reports, ensuring value for candidates.

How It Works

1

Upload Assessment

Candidates upload their psychometric test results (PDF format).

2

AI Processing

AI analyzes the document and generates a structured summary with band rating (A/B/C).

3

Mint on Blockchain

Credential is minted as a Soulbound Token on the Stacks blockchain.

4

Share & Verify

Generate shareable links that employers can use to verify credentials (pay-per-view model).

The platform consists of three main repositories:

  • Frontend: Next.js 14 app with TypeScript and Tailwind CSS (GitHub)
  • Backend: Express API with Mistral AI and Supabase (GitHub)
  • Smart Contracts: Clarity contracts on Stacks (GitHub)

Use Cases

For Job Seekers

Stop taking the same psychometric tests for every job application. Create your credential once and share it with unlimited employers.

For Recruiters & HR

Instantly verify candidate assessments without contacting test providers. Pay only when you need the full report.

For Assessment Providers

Offer blockchain-verified certificates that candidates can share independently, reducing your verification support burden.
