# Blockchain-based Recording of Training and Certifications

> Training and certification documentation often occurs manually and paper-based, leading to problems in tracking qualifications and verifying the authenticity of certificates. Blockchain enables digital, tamper-proof documentation and verification of training and certifications through cryptographic algorithms. According to a 2017 CareerBuilder survey, more than two-thirds of all HR professionals had already encountered fake resumes and certificates, highlighting the problem this technology addresses.

## Description

Resume fraud is a significant problem: CareerBuilder found in a study that 58% of employers discovered lies in application documents — most frequently concerning educational qualifications, job titles, and employment durations. Blockchain-based certificates make such fraud structurally impossible.

The MIT Media Lab developed Blockcerts in 2017 — an open standard for blockchain-based diplomas. MIT issued its graduates digital diplomas anchored on the Bitcoin blockchain that can be verified worldwide instantly. The process: the education provider creates the certificate; cryptographically signs it; anchors a hash on the blockchain; the graduate receives the digital certificate in their wallet. Verification: the employer checks the hash against the blockchain — in seconds, free of charge, without calling the education provider. Additional context: IBM Digital Credentials for training (IBM Skill Academy), Microsoft Verified ID (on Azure infrastructure), Learning Economy Foundation (global network for open educational credentials). In the EU: EBSI Europass Digital Credentials enable cross-border recognition — a diploma issued in Spain is instantly verified in Germany. Increasingly more universities worldwide (MIT, Harvard Extension, Hasso Plattner Institute) offer blockchain-based certificates.

## Benefits

- Companies reduce costs and risks in the hiring process through immediate verification of applicant data without manual inquiries.
- The cryptographic security of the blockchain completely prevents manipulation and forgery of certification data.
- The administrative effort for verifying qualifications is significantly reduced through automated verification.
- The transparent and traceable documentation builds trust among all parties involved.
- Employees gain full control over their digital qualification records and can manage and share them independently.

## Challenges

- Integration with existing HR systems and learning management systems requires technical adjustments and staff training.
- Implementation requires comprehensive cooperation between educational institutions, certification bodies, and companies to standardise processes.
- Organisational risks arise from lack of technology acceptance or missing blockchain expertise within companies.
- Employees must learn to use blockchain-based systems and develop trust in the new technology.

## Technology foundation

This application uses blockchain technology as a digital ledger in which training and certification data are stored immutably. The blockchain's cryptographic algorithms ensure that once recorded qualifications can no longer be manipulated and can be verified at any time by employers or other authorised parties.
