I have an insane idea.... why dont we just broadcast the block reward as
notfound(slice rewardValAfterBlockStarts() )
so was could just declare the value of the block to be x or 0, then after the block begins we update the block hash to reflect the true value ...
You can't change a blockhash... ? That would involve mining another block.
I have no idea what that pseudo-code is supposed to be. But the proper solution would be:
1. each block starts with 2 tx instead of 1
2. the first tx pays the miner a very small reward (maybe .01 in this case)
3. the second tx pays the out address of the first tx in the last block a variable reward (0 or 1 based on the HASH of the last block)
I have a feeling, however, this development is beyond the capabilities of the CGA developer, specifically seeing as he didn't even understand his own simple modifications well enough to realize that block reward was determined before the block was discovered and not after (which should be extremely obvious to anyone that knows the bitcoin protocol).
