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 do Bitcoin payment channels work?

I would like to know how payment channel mechanic works in practice. What do the involved parties need to do, which information they exchange and how is the security ensured.

Bonus question: What different types of payment channels exist?

Only answers that actually explain channels will qualify for the bounty. While linking to 3rd party sources is encouraged and desired, answers that solely do that won’t count.

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!

How does IP2IP work?

I heard a lot of discussions mentioning IP2IP at the recent CoinGeek conference in Seoul. I really like the idea of users exchanging transactions peer-to-peer, but I am wondering how IP2IP works on a technical level?

Does it require a daemon/service running on the recipient’s computer that listens for incoming transactions or is there some other approach?

How to broadcast a transaction to the Bitcoin Peer-to-peer network?

Let’s say a developer wants to broadcast transactions from their app directly to the P2P network (not using RPC calls). How would this be done? I assume a TCP/IP connection needs to be established to one of the active nodes. What follows after that? Which messages need to be exchanged (examples would be very welcome)? Can connection be closed after the broadcast or should the app maintain its connection?

Bonus question: How to discover other nodes and broadcast the transaction to multiple peers in parallel?

Is there any curated list of the IP addresses of the nodes that belong to major miners?

EDIT: It is true that Merchant API will be the way to go when available (it is not at the moment) and that using APIs such as Matter Cloud or What’s on chain is the easiest way to do it right now. But this question is more about understanding how Bitcoin’s server network works. It is an interesting piece of technology. It might also be useful for someone - API providers need to deliver transactions to miners at some point after all.

With that said; this question remains open and bounty still waiting for the right response.

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.
