How many bytes does a P2PKH entry contain? I find some different numbers:
- Why does the default miner implementation use pay-to-pubkey? States:
press + sig + push + key = 1 + 72 + 1 + 61 = 139
- Little Princeton Bitcoin book [p.123]:
The approximate transaction size is 148 bytes per entry[…]
- Knowledgeable Bitcoin Developer Calculated From the Top of Mind For Me On Coffee:
PREVOUT + SCRIPTSIG = 36 + (1 + 1 + 33 + 1 + (71 or 72)) = 143 or 144
I could not find more information in Bitcoin Developer’s Guide or wiki.
Additional question: How are there different numbers? Has the size changed over time?
