How are Bitcoin blocks structured?

Bitcoin blockchain is made of individual blocks. I am wondering how do these blocks actually look like. Which different data types are part of them? What is each part of the block used for, what is its meaning and what are the possible values that can those values take?

I would also like to, assuming I am looking at a block’s HEX blob, be able to decode it/determine various parts of it.

How to create a valid Bitcoin transaction?

If I want to create a Bitcoin transaction, which are the parts I should add to it? What is the meaning of each part and what are any special considerations that I should think of?

I would also like to, assuming I am looking at a transaction’s HEX blob, be able to decode it/determine various parts of it.

I have renewed my subscription for F-Secure SAFE and it is not showing a valid subscription on my computer. What can I do?

Let me start of with saying SAFE rules and it is the best I had so far. I’ve had the program a few years now and it has always been updating the subscription fine whenever I renewed, but this year something went wrong.

I forgot my password to the account and had to reset it, but that can hardly be the problem. Had to update my payment information too, but that was months prior the renewal, so should have given warning if not updated.

So it looks something like this.

SAFE when logged in

Whenever I log in here https://www.f-secure.com/en/home/login/ it says the subscription is valid until next year.

Why the difference between my account and the application on PC? How can I get this yellow warning to disappear. Just sends me here. https://chrome.google.com/webstore/detail/browsing-protection-by-f/jmjjnhpacphpjmnnlnccpfmhkcloaade What do I do next? I use Microsoft Edge normally

How do I create a counter like bitqa.app uses that increases the “Answer: 0” count and stays?

I’m a programming noob trying to build a website using Money Button and BSV blockchain. I need help (or a visual of code) writing code that increases a number on the page after the Money Button is swiped. Just how “Answers: 0” gets increased by +1 on bitqa.app after paying. I hope $5 bounty for best answer is enough. Thanks in advance!
