Question

Which of the four criteria is occurring when a network confirms that a transaction has not yet occurred on the blockchain?

1) Consistency
2) Availability
3) Partition tolerance
4) Durability

Answer 1

Consistency is the criterion occurring when a network confirms that a transaction has not yet occurred on the blockchain.

Step-by-step explanation:

The correct criterion that is occurring when a network confirms that a transaction has not yet occurred on the blockchain is Consistency. Consistency ensures that the data stored in a distributed system remains valid and accurate across all nodes. In the context of blockchain, it means that all nodes in the network agree on the state of the transaction ledger.

For example, if a transaction has not yet occurred on the blockchain, all the nodes in the network should reflect this status and not have any conflicting information. This helps maintain the integrity and reliability of the blockchain.
