## What is the meaning and application of the apostrophes in derivation paths of BIP32 / BIP44?

1

Can we please clarify if there is any difference (because apparently some technical documentation explicitly requests to include apostrophes) between a derivation from extended private key (xprv) or public key (xpub) of a child subkey, where m = root (xprv or xpub).

m/44/0/0/0 and m/44'/0'/0'/0

What are the meaning of the apostrophes and how / when should they be applied? Do they change anything in a derivation path -- will the derived child subkey be different with or without them?
