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

Sagot :

A transaction is stored in the case when a network confirms that a transaction has not occurred yet on the blockchain. Hence, option C 'a transaction is stored' is the correct answer.

Blockchain is a system of recording information in such a way that makes it difficult or impossible to hack or change the system. A blockchain is generally a digital ledger of transactions that is replicated and distributed across the whole network of computer systems on the blockchain. In other words,  blockchain is a distributed public digital ledger that is used to record transaction-related information across many computers so that the transactional records cannot be altered retroactively without the modification of all subsequent blocks and the consensus of the network.
