CAP Theory

Question 1

CAP

Answer 1

Consistency,
Availability,
Partition Tolerance

Question 2

What is CAP Theory

Answer 2

CAP theory states that a distributed system can achieve at most two out of three guarantees:

Consistency,
Availability,
Partition Tolerance

Question 3

Consistency

Answer 3

All nodes see the same data at the same time.

Question 4

Consistency Relevance

Answer 4

Ensures all users see most up-to-date state

Difficult to achieve due to decentralized nature of DApps

Question 5

Availability

Answer 5

Every request recieves a (non-error) reponse regardless of the individual nodes state

Question 6

Availability Relevance

Answer 6

DApps must ensure high availability, meaning the system should be able to process transactions, even if some nodes are down or delayed.

Question 7

Partition Tolerance

Answer 7

System continues to operate despite arbitrary partitioning (communication breaks) in the network.

Question 8

Partition Tolerance Relevance

Answer 8

The system needs to function even when parts of the network can’t communicate with each other.
