In such case, how does the recovery function work if one is recovering the coins to a new ledger device by using the 24-word phrases and the user info? How does Ledger Live able to transfer the private keys to the new device? Is it being done using some type of encryption conversion?
Your 24-word seed holds all the private keys of all the addresses of all cryptocurrencies which Ledger supports. That's everything that you need to recover everything you own. So once you input your 24-word seed to a new device for recovery, all the private keys will be restored there.
You need to take note that your private keys are not stored in the Ledger Live app. There is, therefore, no transfer that happens from your Ledger Live to a device.
So the private keys of all the supported 1000+(?) cryptocurrencies are all somehow embedded in these 24 words?
Yes.
I would thought that the private key for a coin address is created after user install the coin app and deposited the coin.
No.
I guess Im still a little confused on how private key works. Isn’t a private key associated to a transaction after an exchange is made?
It depends on what you mean by
associated here. But a private key is not derived from a transaction.
For example, if I haven’t transferred any BTC into the BTC account, would there be a private key associated to the account?
Yes. There is always a private key in every public key which is where the public address is derived from.
Is the function of a coin (ex, BTC) app just to help user to see the specific coin info and to manage the coin?
If I installed the EOS app and transferred 100 EOS coins to the ledger. Later, I deleted the app to gain more space back, would the 100 EOS coins still be in my ledger wallet address? If I reinstall it later on the same device, would I be able to see the 100 EOS coins? The reason why I’m so concerned about this is because I got a Ledger Nano S which can only hold 3 of coin apps. I need space for 7 other coins that I need to transfer.
1. Yes, the app will allow you to manage your coins.
2. Yes, even if you delete the app to make way for another app, you can re-install it later on and still have your funds intact.
Also, does Ledger Live store the information that my EOS account has 100 coins?
Yes, you can find it under
Accounts.
Else, if I use the 24-word phrase to recover my coins to a new ledger device, how would the 100 coins be there?
Because, as I've said, your 24-word seed holds everything. It does not mean that since you uninstalled your EOS app from your device, that it doesn't show there anymore, that you cannot manage it anymore, you already have deleted your private keys. Your EOS private keys are still safely stored in your device even if you uninstalled the app. So once you re-install it, you will find that it is still there. And once you input your 24-word seed on another device, it is also restored.
I know this is a lot of questions, but please be patient with me.
