P2PK

Pay To Pubkey

P2PK (Pay To Pubkey) is a script that locks an output to a public key.

It is a simpler version of the more-commonly used P2PKH lock.

Example

scriptPubKey (locking script)
4104a9d6840fdd1497b3067b8066db783acf90bf42071a38fe2cf6d2d8a04835d0b5c45716d8d6012ab5d56c7824c39718f7bc7486d389cd0047f53785f9a63c0c9dac 04a9d6840fdd1497b3067b8066db783acf90bf42071a38fe2cf6d2d8a04835d0b5c45716d8d6012ab5d56c7824c39718f7bc7486d389cd0047f53785f9a63c0c9d OP_CHECKSIG

A P2PK lock just contains a public key and a CHECKSIG opcode.

When you want to unlock a P2PK lock, you just need to provide a signature for that public key.

Hey there, it's Greg.

I'll let you know if something seriously interesting happens in bitcoin.


Don't worry, it doesn't happen very often.
