### How to get Private Keys for the corresponding HD generated Child Public Keys?

If we take a look at the Mastering Bitcoin book by Antonopoulos it is explained how to derive child keys as described in BIP-32: From this image it is easily visible that we can use parent public key ...

### Does derivation from public and private keys give the same result in normal key derivation?

I am reading about key derivation in chapter 5 of the book "Mastering Bitcoin" by Andreas, along with this detailed thread and BIP-32. Here are some of my understanding about these two ...

### Unable to derive child keys from subkeys

I'm trying to implement bip32 derivation and have been able to derive the child keys from the master node, but not children of the child key. The following test shows the correct result in bytes for ...

### According to BIP44 each HD wallet have a finite number of 2^32 addresses, Why is that the case?

According to BIP32 we can have a seed from which we derive all our private and public keys, so in theory we can have an "infinite" number of child and grandchild keys so why does BIP44 limit ...

### Can't Access funds due to derivation path

I created a seed phrase and public key via the following Node.js code: const mnemonic = bip39.generateMnemonic() const seed = await bip39.mnemonicToSeed(mnemonic) const node = bip32.fromSeed(seed) ...

### How are derivation paths stored and regenerated for HD wallets?

HD wallets create derivation paths for generated keys. But if you need to regenerate these keys with your seed or master key, where do you get the derivation paths? I don't see how they can be stored ...
