Has the Script been changed since the Genesis Block? I am having some problems figuring out how to process this scriptPubKey from that block: This transaction uses the en. In it you have the public key itself before any hashing step 1. The public key in the genesis block is afdb0fef1abcd6aeae0ea1f61debf6bc3f4cef38c4fe51ecde5cdf7ba0b8da4cb6bf11d5f, I'm not sure where you got this value from. It's the same public key, but with opcodes added on both sides - push 0x41 bytes on the left and checksig on the right.
So it is a raw scriptpubkey dump from en. Sign up or log in Sign up using Google. Maybe a link to some open-source software which creates custom script transactions would be helpful.

Bitcoin uses a scripting system for transactions. Forth-like, Script is simple, stack- based, and processed from left to right. It is intentionally not Turing-complete, with no loops. A script is essentially a list of instructions recorded with each transaction that describe how the next person wanting to spend the Bitcoins being. In order to use this tutorial, you will need to setup Bitcoin Core and create a regression test mode environment with 50 BTC in your test wallet. .. But the data that gets signed also includes the pubkey script from the previous transaction, even though it doesn't appear in either the unsigned or signed transaction. In the other. Script. All bitcoin transactions have scripts embedded into its inputs and outputs. The scripts use a very simple programming language, which is evaluated from left to right using a stack. The language is designed such that it guarantees all scripts will execute in a limited amount of time (it is not Turing-Complete). When a .
