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?

Which exchange should be used?

Of all the exchanges mentioned in Discord, Telegram, Slack and Twitter, none seems to stand out as the obvious choice. All seems to have had their good share of shenanigans, on way or another. Either by delisting, which is an obvious no go, or more dangerous business models like hyperleveraging, crypto loans and worse.

Which will be the first BSV application that will catch mainstream adoption?

Now, this will obviously require some speculation, but why not. There are many exciting Bitcoin SV applications being released practically at a daily basis, but they are arguably mostly used by the (still small in grand scheme of things) BSV community.

I predict that at some point we’ll see one/some of those applications gain attention of the general public and take off - probably dragging the entire ecosystem with them.

If you could bet which (or what kind of) app that will be, what would you bet on?

Double hash in Bitcoin

what exactly is this? Does this mean every TX gets hashed twice? How does it help to filter the content from the block chain (As Dr. Wright said)? Why cant i hash it just once and save the hash of the TX and prune the data (illegal)? Isnt the content now filtered with just a single hash? or am i getting it wrong?
