Data handling |
Supports four primary operations: create, read, update
and delete |
❌ |
Only read and write options are available |
✔ |
Authority |
Controlled by the administrator (centralized) |
❌ |
Decentralized even in private blockchains |
✔ |
Data Integrity |
Data can be altered |
❌ |
Data is immutable and
auditable |
✔ |
Data Privacy |
High chances of malicious cyberattacks |
❌ |
Data is
stored using cryptography technology |
✔ |
Transparency |

❌ |
Data is stored in a
distributed network |
✔ |
Quality assurance |
Administrators are needed to authenticate data (data
provenance not applicable) |
❌ |
Data can be tracked and traced right
from its origin using cryptography technology |
✔ |
Fault tolerance |
High risk of single point of failure |
❌ |
Distributed
ledger is highly fault tolerant. |
✔ |
Cost |
Easy to implement and maintain as it is an old technology |
✔ |
Uncertainty in the operating and maintenance costs |
❌ |
Performance |
Fast (more transactions processed per second) and offer
great scalability |
✔ |
Can handle minimal transactions per second and
scalability is a challenge as blockchain is at its developing stage |
