BitcoinUnlimited is ahead of it's time still, Ethereum is a bit further than that.
How much people, power, etc. does it take to maintain a financial/value system, and who can do it better?
Bitcoin is up for bid.
Good luck.
Would this be bad?
I don't think it necessarily has to be bad, even if this would be true.
As long as there is not 1 instance in control, it's still decentralized, no matter if it's bots or humans.
Let us say that at some point 51% of the bots will be controlled by one group. How is that decentralized and how is that good? It might be happening now with Bitcoin. The top Chinese miners could be talking behind closed doors right now.
they run node to supply the S&P500 server ?
no.
reality of privat network.
stock exchange server are closed.
not Bitcoin.
Bitcoin never will be as decentralized as you think.
Does not matter how many times you say it is.
So what is the advantage of your proposal? What economic, efficiency and security advantage can it have over the system that we have today?
Proof of Work is all about hash power, the more Bitcoin has the more it is secure. The more the miner provides, the more chances he gets rewarded. What does your bot idea have?
*Nothing will ever be as decentralized as you think.
