EXPLANATION :

Answer the questions

PROOVE :

1. 2 more types of certificates

• • Method for Identity-Verification
  • Mechanisms for Regulation and Assurance

2. Please provide examples of blockchain applications other than certificates

• • Ledgers

3. Why do we need trust of the Certifications?

• • The final element for trust in a certificate is for the claim to be easily accessible. This
    implies that:
    • the recipient of the certificate should be able to hold a copy of the certificate;
    • third parties who require access to the certificate should be granted it easily either
      by the holder, the issuer or a registry;
    • the certificate should contain information as to how to verify the claim, and the
      standards and processes used to make the claim and issue the certificate;
    • the information in the certificate should be clear, legible and easy to use. Ways to
      do this include:
      • standardising the content of the certificate itself;
      • ensuring that the certificate is machine-readable.

4. Who should be trust?

• • Blockchain technology is secure as it is decentralised and distributed. There is no single point of failure, which makes it much harder to corrupt. Hacking into one part of the system cannot affect other parts.

5. What certificates in education can be implemented with blockchain technology?

• • Uses of Certificates issued to Learners
  • Use of Certificates for Accreditation
  • Uses of Certificates for Tracking Intellectual Property
  • Uses of Certificates for Financial Matters

6. Mention other advantage and disadvantage, apart from those described on the previous Blockchain Certificated!

Advantage

• • they require far fewer resources to issue, maintain and use, since:
    • the veracity of certificates can be checked against the registry automatically,
      without human intervention;
    • where a third-party needs to use the certificates, these can be automatically
      collated, verified and even summarised if they are issued in a standardised for
      format;
    • the security of the certificate derives from the security of cryptographic
      protocols, which ensure that the certificate is cheap to produce but extremely
      expensive to reproduce by anyone except the issuer;

Disadvantage

• • without the use of digital signatures, they are extremely easy to forge;
    • where digital signatures are used, these require the involvement of third-party
      certificate providers to guarantee the integrity of the transaction – these third
      parties have significant control over every aspect of the certification and verification
      process, which can be abused;
    • in many countries, there is no universally-used open standard for digital signatures,
      leading to certificates that can only be verified within the context of specific
      software ecosystems;
    • it is easier to destroy electronic records – keeping them safe requires sophisticated,
      multi-tier backup systems which are prone to failure;
    • should the registry fail, the certificates themselves become worthless since unlike
      paper certificates, they hold no intrinsic value without the registry;
    • registries of digital certificates are prone to large-scale data-leaks.
