So we have a pool of agents, they can send binary blobs, they need to have X many tokens per day to survive (start it low, let it grow over time), they need some way to mine a blockchain, allow some way for them to reproduce via genetic ai & random mutations, add in some misc mechanism of disaster in order to reward saving for a rainy day, maybe add in a mechanism where agents can group up to kill other agents, see if they evolve a means of striking deals & splitting up loot for future attacks

Then eventually add a human console where people can invest in agents, see if the agent will give out returns, eventually allowing agents to put smart contracts on ethereum & interact with misc smart contracts..
