It is good that Blockcerts has created this open source tool for creating blockchain certificates. Companies like learningmachine are partnering with universities to issue blockcerts verifiable certificates. Which is great. But this is only addressing the problem with new certificates.
What about the certificates that are issued already? There are trillions of certificates already issued which are either in PDF or image formats. Take my case. I completed my university studies decades ago and not planning to go back anytime soon. I have bunch of paper/PDF certificates with me. How can I convert this into blockchain certificate?
To solve my problem, I created a tool to convert any PDF of image certificates into blockcerts and found it useful. Then I created a nice user interface and started uploading all my important documents. I’ve deployed this at https://proofplum.com
The certificates created by me are not endorsed or verified by respective universities. But we are planning to add simple workflow to add verifications in future.
While playing and tinkering I also found other uses for blockcerts. Blockerts certificates not only addresses the problem of verification. It also solves the problem of storing and sharing certificates easily.
This solved another problem for me. All my important certificates and documents were scattered around multiple cloud storage services. Now I was able to organize all of them in one place.
Anyone can signup and drag/drop to create blockcerts certificate. The hash is anchored in Ethreum blockchain and passes all blockcerts validation. The PDF or image document is converted into base64 bytes and stored inside the json file. So json file can recreate the actual certificate without any external dependencies.
It is always better to see it in action to believe it. Go ahead, sign up at https://proofplum.com to drag & drop a document.
Any feedback both positive and negative is much appreciated.
