signature of the originating node in a mined block

+2 votes
Dear Multichain team,

according to the following answer:

after the mining process, the block contains the miner signature in the coinbase field.

Does it contain the original signature from the user who created the transaction and signed it before sending to the network?

The short answer is yes. The long answer is that every transaction is signed, and the signature(s) form part of the transaction. Transactions are embedded in the block in full, so yes the block contains all transaction signatures.

Thanks for your support.
I set this question because I found that some implementation of DLTs or private blockchains have the miner nodes removing the signature from the originating node after the validation. In such case there is no proof of the signing action from the originating node if  not fully relying on the miner itself.
Understood, that does not happen in MultiChain.
