As Cambridge Dictionary states, AI or Artificial Intelligence came from 2 words, "Artificial" which means "made or produced by human beings rather than occurring naturally, typically as a copy of something natural." and "Intelligence" which means "the ability to acquire and apply knowledge and skills." Combining those two things would provide a shorter explanation of "The ability to acquire and apply knowledge and skills made by humans." These capabilities may be result of statistics or experience brought from the pasts.

As we know, even if Humans are smarter than machines, machines still function more efficiently and faster than us. Built with series of programs and instructions, they can compare things and statistics within mere seconds. Applying AI to the blockchain would make transactions faster and efficient.

If there would be an AI project, I want to it to have in relations with gaming. Banning players that would flame others for their "fun" and Decentralizing the Crypto to be used in gamification and as monetary value in games like the Chimaera. You would be able to buy in game items that would have a value in the real world and the transactions are all monitored by the AI so that it would be fair and no human mistakes can occur like late payment and stuff.

On the more serious note, having the AI technology govern important aspects that may affect our lives like a part in the government or budget schemes would be a big no. AI or Artificial Intelligence grows by seeing past results. If we are only looking at the past, we cannot adopt to the changes in the future. We are humans and we grow each day. I believe AI may be a part of the crypto world, gaming, etc. but should only be given minimum power, like as an advisor for the current crypto to buy but never more than that like holding your own money and doing daily trades. AI learns and may not abide your will if they "learn" too much.
