user76580: Suppose I wanted to track transactions by an individual entity in the Blockchain, say Mr. Smith. Is that possible?

user54178: Yes & No
You can track a person's transaction only if you know that person's wallet address/es
By the wallet address/es, you can see the transaction.
The incoming transaction can be a buy, or a sale completed, etc.
The outgoing transaction can be a sell, or a purchase, etc.
You can also track a person using all his xpub key to know all the address/es at once.
Buy you cannot track a person just with a name or a single wallet address (if he owns multiple, which at this time, people do).
Hope this answers your question.
