This question is linked to this one. I try to understand the bitcoin block by exploring and viewing every piece of information, since the blockchain is public and shared.
When the sender transacts some bitcoins to the recipient, he technically transact previous transactions. So in a transaction, it is possible to find successively all previous transactions. Where can we find this piece of information? (I remembered that I already saw this information on a website, I thought that was https://blockchain.info.)
