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.
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.
I have been asked this question a number of times and haven’t found an adequate answer.
The reason for the US going to war in Korea is pure propaganda (stop communism from spreading).
What is the real reason and motive?
One can ask Bitcoin SV not to provide a proof that a given transaction was included in a block. E.g.:
➜ bitcoin-cli gettxoutproof '["ea32120687851afe3418ab3642af94a4c69684e4b87f8a529807489e09d74ec5"]'

Proof can be verified using the verifytxoutproof RPC command, but let’s say I would like to verify the proof in a custom application that does not have access to a Bitcoin node.
How can I decode the proof HEX blob? What data is part of it and how can I get block, merkle proof and transaction information from it?
Can I just use ElectrumSV with an alternative derivation path?
Please provide step by step instructions. If you go above and beyond with screenshots and more info, then I’ll tip another $5.00 on top.
Thank you!
Lots of my friends family members have died of cancer. Neighbors family close friends the big question is is there a non-toxic medicine that can cure cancer fully
Since these two opcodes will be removed after Genesis and (from my understanding) nLockTime works in a slightly different way (prevents transaction from being included in a block vs. UTXO being locked until given time/block height), how will be possible to achieve same functionality after that?
Is it possible to build a locking/redeem script using other opcodes that achieves the same result? Or is there something else?
Are there any miners that already support Merchant API? What are the URLs of their Merchant API endpoints?
