Intent behind "sendrawtransaction"

Question

Hello Multichain Team,

I was working with multisig addresses and transactions from 
https://www.multichain.com/developers/multisignature-transactions/

While following the tutorial, I found this command :
sendrawtransaction [paste-bigger-hex-blob]

I want to know what is the intent behind this command. Like, normally after signing the transaction on the second server, why it's not automatic to publish the changes to the blockchain?

Answer 1

All the raw transaction APIs modify the transaction as an isolated data structure, but nothing actually happens on the blockchain until sendrawtransaction is called. We could of course add a parameter to signrawtransaction which transmits the transaction immediately after it is signed, but we haven't done this for now.
