I think I hacked the exchange:
wallet_PK == network_params.exchange_cold_address
true
And then, I can just turn off my miners, and see, how the whole network will give me all coins.
By the way, I wonder, if you want to make it similar to Cookie Clicker, where the latest possible cookie maker is called "JavaScript console".
you can pre mine the same number of blocks or more to verify (or wait, but it's the same thing)
No, they are not the same. If you generate blocks from the command line, then the difficulty doesn't change. However, if you let the difficulty grow exponentially, then it can reach some limits, where producing next blocks is no longer possible.
And unless you leave the game running for the next hundred years, I don't think timestamps nor chainwork will overflow
Chainwork will overflow quite quickly, if it can grow exponentially. If you have 2^256 maximum chainwork, then if network hashrate will double only 256 times in a row, it will always overflow. And I guess, if you fixed it that way or another, then it will just shift the problem from block number 3067 to some bigger value, but I guess there is still some limit, and now I am trying to check it.
