Technical and philosophical uncertainties aside, I don't thing a blockchain is a suitable medium for humanlike consciousness. A blockchain exists to lock down a state irrevocably, and state changes are encoded in new blocks referring to the old ones. If you think the Bitcoin blockchain is bloated. just try storing every neural operation in one... Besides, neural rewiring, malleability of memory etc. seem like pretty important parts of being a live person to me.
We'll just have to do with our memories of those lost for now.
Watch this. This guy is the CLOSEST IN THE WORLD to achieving Artificial Intelligence. And to me it seems like he is missing a block chain to make the computer more than a computer.

There will never be "spiritual machines" or true
consciousness/awareness in a computer.
Yup. Searle's paper was one of the first that I read when studying Artificial Intelligence. I don't believe that we will ever achieve Strong AI, but that doesn't mean that it isn't possible, just because I can't comprehend it.
Going back to the OP, I don't see how a blockchain would provide a suitable model for querying. There is a lot of work using neural networks, multi-layered perceptron etc for providing decisions based on information seen.
The real skill is how do you model the knowledge such that it has features which are comparable and there to be queried. You could build a rudimentary model, but the responses would be somewhat contrived. Also the best training when building such a model would include the person themselves, in addition to other people such as family, friends, co-workers etc.
Sorry to hear about your brother's passing btw, it's interesting that you are seeking ways to preserve his life. Sometimes memories are not enough.
The Block chain could process questions like transactions, and the hash rate would be the thinking speed of the AI. And people around the world could ask questions and join the network to help keep the bot alive.
Eventually it could even be a system of bots that all worked on one hive mind and there could be like teddy bears that answer questions for kids.
I am not trying to preserve him, I understand that his mind is gone. I preserve him in my own ways.
