Question on code Re:block reward

[bones261]

I'm just curious, exactly what code in BTC and it's many clones, prevents someone from changing the block reward code, compile their own wallet, and mine at a higher reward?  I'm probably missing something very fundamental here, but the only stupid question is one that isn't asked.

Every block that's mined has to be validated by peers. If it doesn't pass validation, then other miners won't build blocks on top of it. Obviously changing coinbase reward might be something that makes a block fail validation.

Thanks, that makes sense.

If anyone can point me to the files that contain the code, that does this magic. I'd appreciate it.

The answer lies in consensus. Unless the network agrees with your changes, they will be rejected.

Code changed software will be rejected by others and its user are mining altcoins!

They will be immediately rejected and become orphans

The second you mine a block with different parameters that is accepted by other nodes running the same code, you are on your own fork

Writcoin[™] . . . defines a blockbase™ transaction as being any coinbase transaction with only one, unspendable output.

One's efforts would prove fruitless within the network referenced above.
