This means the transaction is verified using a Merkle tree structure without broadcasting it to the public blockchain.

Still, using a dedicated smartphone as a Bitcoin wallet does not make it as secure as a hardware wallet (which is designed to be entirely offline and immune to online threats).

BitcoinLib may be a good choice. Plenty of examples out there are capable to help you get the hang of it.

It's possible that the IP address range assigned by Internet provider B is flagged by bitnodes. io or other services due to previous activity or network behavior. This could result in your network being subject to additional scrutiny or review. If so, you need to contact Internet provider B's customer support.

Is the wallet file you are attempting to open compatible with the version of Bitcoin Core you are using? Is there sufficient disk space available where the Bitcoin Core data directory and wallet files are stored?

Consider upgrading the toolchain if you intend to build from source frequently or contribute to Bitcoin Core development.  Upgrading may involve multiple steps, but it's beneficial in the long run for compatibility with newer software.

BitMaxz has provided a great explanation. For question 4, one additional point to consider is an older GitHub page that might be helpful to you:https://github.com/BitcoinPHP/BitcoinECDSA.php

BitcoinJS-lib is a JavaScript library for Bitcoin scripting and works both on Node.js and in web browsers.  It allows you to create, manipulate, and interpret Bitcoin transactions.  You can install it using npm with `npm install bitcoinjs-lib`. And here is the link: https://github.com/bitcoinjs/bitcoinjs-lib

Hope this is helpful.

nc50lc has already provided a great answer to your question. I just wanted to add that the official Bitcoin Core documentation offers comprehensive insights into commands, usage, and wallet management. You can access it here: https://bitcoincore.org/en/doc/

Do you mean that some desktop environments or file managers maintain a list of recently accessed files? I usually ensure proper data wiping using tools to securely delete files and overwrite the data multiple times to prevent forensic recovery. And maybe you can consider running it in a more controlled or isolated environment, like a virtual machine or container, to contain its activity.

If you send Bitcoin to the address derived from this invalid private key (1NLqpZnW746xjdAgnrTb56V4uZJiV4jjrU), the funds will be associated with that address.  However, since the private key is not valid, you won't be able to sign transactions to spend or transfer those funds.  In essence, the funds sent to that address would be irrecoverable.

Am I right?

You need to communicate with the founders or administrators of the private blockchain network and work within the rules and permissions they have set. Or,  if you can become a node operator within the private blockchain network, you may have the ability to participate in the consensus process and mine blocks.

I don't know much about it, but I've seen websites about it before from other sources. I hope this can help you.

Thank you all for your valuable insights and assistance. I plan to take the next few days to explore refurbished laptops online, based on the advice you've provided. Once again, a big thank you to each one of you for your help!

That's the reason to seek out trustworthy refurbishers and assess the device's initial build quality. Reputable refurbishers go the extra mile by either replacing or refurbishing essential components, ensuring the device functions well and enjoys an extended lifespan.

Then another important question arises: how can one identify a reliable refurbisher?

You're absolutely right, this kind of business with refurbished business laptops is quite common worldwide. While affordability and durability are key advantages, ensuring the security of these devices remains a crucial consideration for me.

Non-technical-user-friendly, sounds interesting. This approach simplifies the process of setting up and maintaining a Bitcoin node on a Mac, making it more accessible to a wider audience.

Your response broadened my perspective on this issue, and I appreciate your suggestion. It's indeed worth considering purchasing a used laptop with a suitable SSD, and your detailed considerations provide valuable guidance. Thank you for your helpful input!
