Difference between crypto coin vs crypto block? I have several doubts about cryptocurrency when I started(bitcoin) reading about it. I google it around and it only added to more confusion.

I am not able to understand the difference between a bitcoin transaction block and a bitcoin as a coin. Aren't bitcoin currency also a bitcoin transaction block in case of a newly minted bitcoin?

Bitcoins are mined after solving cryptographic puzzles, but in the initial days did the author(s) had to create lot of unnecessary transaction to solve the puzzles to create new coins until the general public picked it up? (Or how did they create currencies without any transactions in initial days)


I hope the questions are clear. Do let me know if it needs more editing/clarifications.

A bitcoin block contains the most recent transactions, i.e. Person A sends Person B 10 bitcoins. It works like an old fashioned record book, where all the transactions are written out.
The first record in a next block is a transaction that awards the winning miner (who completed the previous block) the newly minted bitcoins.

The initial block does not contain any transactions, it only contains the reward to the miner of this block. The first block is also called the Genesis block.
Watch this video (&quot;But how does bitcoin actually work?&quot; from 3Blue1Brown), it explains it really well with more details.
