 Please keep in mind that Public key type always has only one registering key, so the gas would be always 20000.

 Basically, `PayloadGas` is charged with `number_of_bytes_of_tx_input x TxDataGas (100)`.
 
 In the case of a transaction creating contract, an additional charge of `number_of_words_of_initcode x InitCodeWordGas (2)` is applied. It is effective since Shanghai hardfork.
