P2PK
Pay-to-Public-Key — an early Bitcoin output type that locks coins directly to a public key.
P2PK (Pay-to-Public-Key) is a transaction output type that requires a valid signature for a given public key to spend. Unlike P2PKH, it does not use a hash of the public key, so the public key is revealed when the output is created.
- Used in early Bitcoin blocks and coinbase rewards
- P2PKH became preferred for privacy and compact addresses
- Modern wallets rarely produce P2PK outputs
