Comments

Which API are you calling and can you post the output as an example?

Answer 1

This field is of type long. It means this transaction is part of a block and after that block, there are blocks added. The number of blocks added after the transaction block is the value specified in the confirmations. From Block Chain perspective and security analysis, the more number of confirmations brings in more confidence to the transaction in terms of acceptance by business applications. If this transaction is to be changed by some one, than all the confirmed blocks are also needed to recomputed. 

The below command to decode a transaction should provide the confirmations field for example:

multichain-cli chain2 getrawtransaction f79c2ff75665f714c25569469bb3c841a5d188f916e687973320878c2a4103f4 1
