P2PKH (Pay-to-Public-Key-Hash)
P2PKH is a Bitcoin address type that hides the public key behind a hash until the holder spends from the address.
Addresses starting with "1" use the P2PKH format. When you receive Bitcoin to a P2PKH address, only the hash of your public key is visible on the blockchain. Your actual public key is revealed only when you spend, which provides protection against quantum attacks on stored (unspent) coins.
