If I have an idea for a use case that requires transparency and ultra-secure final settlement, how do I go about programming this to be a side chain/2nd layer solution on the bitcoin network? Is there a specific language I’ll write in? A specific client? A specific IDE? Where can I get started?

I’ve held some cash in an app called Coinbox, by Coinbox Inc. (1m+ users according to Google Play) and wanted to transfer it today. It seemed to have lost its functionality, so I uninstalled and reinstalled with the hope that would solve the problem.

Unfortunately now it has suddenly ceased to exist on Play and I have not had a response to my support ticket to the developers. I’ve also tried installing old apks of the app on my android phone and they don’t connect or won’t install.

I have my passphrase and QR of the account and even have some screenshot of when it was installed but is it safe to say my portfolio is lost if the developers don’t restore the program or respond to my messages?

I have a task where I need to set up some sort of a listener on a particular bitcoin addresses for incoming transactions, and once a transaction arrives, I need to call some function in my web service. Is it possible to have some sort of an event be triggered by the incoming bitcoin transaction that calls my web service? What technologies or tools are available that I could use for this task?

Furthermore, after the function in the web service has completed, I need to forward those received bitcoins to another address using that same web service. The web service can, if needed, be provided access to the private key for the address from which these bitcoins would be sent out. What tools/technologies could I use for this purpose?

Is it normal if a plugin that I’ve written doesn’t shut down (ie the Python process is still running) after I’ve called stop_ln (in the startup_regtest, start_ln setup)? Is the plugin opened as a subprocess? Should it handle a particular signal?

This was asked on Telegram.

I am just wanting to clear up a few details of the bitcoin immature_balance.Such as how to create the immature_balance? How to increase or reduce the immature_balance? And where is the cpp file which is concerned?
I can’t found the cpp file which is concerned. So would you please tell me where is the cpp file in which immature_balance function concerned? Thank you very much.
By the way , my bitcoin version is bitcoin-0.20 and it runs in segtest mode.

I just learned about BIP85 today. It will generate a new seed that I don’t need to back up.
I think it is pretty cool to only have to backup my one BIP39 seed and the index of BIP85.

However I started to think that this BIP85 can be used for something malicious. A wallet developer can make a wallet to generate a BIP85 seed from that wallet developer’s BIP39 seed. So I wonder how can I verify the seeds that I got from some wallet software/hardware are not a BIP85 seed?
