Rather than trying to explain how Tauchain works which might not really be important to non-AI researchers, I am focused on explaining what Tauchain can do for you. Some concepts you can use:

1 **Bounded rationality.** The idea that there is a limit to how rational a human mind can be. The only way to transcend this limit is through the extended mind (external mind).
2 **Debiasing.** Humans are biased. No matter how hard we try, we are biased and this includes stuff like racist, sexist, homophobic, ageist, nationalist, globalist, just fill in the blank. 
3 **Effective altruism.**  Humans aren't very good at ethics or altruism.
4 **Efficient market hypothesis.**  Markets are not efficient.
5 **Social limits of the brain.** Dunbar's number.
6 **Forced ignorance.** We don't even get a choice because we cannot process the complex world as humans and need help.
7 **Attention scarcity.** We lack an ability to have unlimited attention because conscious attention is scarce.
8 **Accelerating complexity.** Which requires a greater ability to process information and knowledge than our brains will be able to support.

I think asking how Tauchain works is a bad idea right now because only the experts who are going to peer review it will understand how it works. People don't understand how the Internet works or the OSI layers but still use it. People don't understand how email works with SMTP but still use it. People don't understand how video streaming works with WebRTC but still use it. People don't understand how Bitcoin or Ethereum works but still use it. **All people really need to understand (newbies and the masses) is what Tauchain can do for them.**

Sorry I cannot come up with a better answer but explaining the how is never simple when it's dealing with AI. How does Google work? Most people don't understand that and don't care as long as it returns increasingly more accurate results each year. More details in the form of papers (one of which will be for everyone not just experts) will help elucidate Tauchain. Please wait for the official whitepaper by Ohad Asor.

Try to consider what something like Tauchain can do for you. Imagine a world where AI is accessible like electricity or water or any utility, where it's not centralized or locked away, where it's not a research toy, but where you can use AI to improve your life and productivity?

AI, think autonomous agents, think intelligent assistants, think bots, etc. But think of these intelligent assistants with the ability to learn and have common sense! What would you do with that? Think about if these intelligent assistants can interact with any sort of smart contract, think about if contract law can be understood by these intelligent agents? How might it change concepts like marriage, or dispute resolution, or alter the concept of a company or firm? The blockchain and smart contract infrastructure we have now doesn't have the capability to do AI, so what happens when that changes? Now you have **Great Automation** combined with smart contracts and blockchain. What could you want to do with this?

Even if you don't understand how Tauchain works, you can dream and post on what you'd like to do without even referencing Tauchain. When Tauchain arrives if you are a stakeholder, you will simply reference back to your previous sci-fi looking blogposts and reveal that Tauchain has made it all possible and here is how to access it.
