Why Open CPD Uses Distributed File Networks for CPD Accreditation

Blockchain technology has transformed decentralised computation. Systems like Bitcoin revolutionised financial infrastructures with secure, immutable ledgers. Ethereum advanced this by enabling smart contracts, laying the groundwork for modern blockchain applications. However, even the most advanced chains face limitations—notably the challenge of file storage.

At Open CPD, our mission is to ensure that CPD accreditation remains accessible for small training providers. While blockchain-based systems can be secure and immutable, their complexity and costs—such as high gas fees—can be barriers. Our distributed file storage approach balances innovation with simplicity, providing tamper-proof certification without unnecessary expense.

The File Storage Challenge

Blockchains excel at recording transactions and securing data but are impractical for storing large files due to high fees and resource demands. Traditional solutions, like cloud storage, offer alternatives but can lack the transparency and verification required for certificates and digital badges.

Immutable and Verifiable Storage

Open CPD prioritises immutability for your certificates and digital badges. Once issued, these assets cannot be altered, reinforcing trust and accountability. Our distributed storage technology assigns cryptographic hashes to certificates, enabling verifiable authenticity without needing to store data directly on the blockchain.

Importantly, Open CPD ensures flexibility: issuers can disable certificates issued in error. Additionally, certificates can be set to expire automatically, prompting recipients to retake training when needed.

Distributed Accessibility

Our technology stores certificates and badges across multiple nodes instead of relying on centralised servers, making them resilient and always accessible. This approach ensures that training providers maintain full control while benefiting from tamper-proof, secure credential issuance. Once issued, certificates remain verifiable, building trust with recipients and their employers.

Practical Applications

Our advanced file storage system enables training providers to offer secure, tamper-proof CPD certificates and digital badges. Recipients can easily share and validate their achievements, while providers benefit from simplified accreditation management and enhanced transparency.

Why It Matters

Distributed file networks solve one of the core challenges of blockchain applications by making secure, scalable, and cost-effective storage possible. By integrating these technologies, Open CPD ensures that your certificates and digital badges are stored reliably, verifiably, and accessibly.

With Open CPD, small training providers can deliver high-quality learning experiences, confident that their accreditation process is efficient, transparent, and secure. Additionally, Open CPD is prepared to offer fully blockchain-driven certificate storage as soon as technological costs decrease, making this approach accessible to SMEs.
