These digital certificates have several advantages over physical certificates:
- They are more secure and difficult to counterfeit.
- They are easier to store and manage.
- They can be shared and verified instantly.
Comparison of digital certificates with blockchain and physical certificates:
| Feature | Digital certificates with blockchain | Physical certificates |
| Security | safer | less safe |
| Easy to verify | Yes | No |
| Portability | Digital and physical | Limited |
| Durability | Permanent | little |
| Cost | Cheaper | More expensive |
Digital certificates with blockchain offer a number of advantages over physical certificates. They are more secure, easier to verify and share. They are also cheaper and their implementation is faster and easier.
Today, blockchain-enabled digital certificates are being used in a variety of applications, such as education, vocational training, and employment. As blockchain technology continues to develop, blockchain-enabled digital certificates are likely to become even more popular.
