Blockcerts is an interesting tools and we are using it for this project http://contratos.datahome.mx is only beta version and we are only testing, but please any feedback is very welcome.
Only create new account, login, and enjoy. (remember is beta versión thus maybe have errors)
Add more information -----
This projects is using :
Backend : Python3 --> Django 2.0
Front-end : HTML5 - CSS3 - jQuery
and for certificates --> Blockcert’s Tools - ethereum network.
The idea is, you can upload any file(audio, image, doc, etc) and this project get other info, and make certificates json(dinamically with blockcerts) and with this info, stamp into the blockchain.
After we can print PDF file certificates for this file(previously uploaded) and proof authenticity.
