20020526T Santa Cruz, CA: I took a break from blogging, so plan to revisit some of the tweets I made on each day that I didn’t blog. The above are from May 21st.
Spacetime Independent Probabilistic Blockchain: Blockchain is today used to permanently capture/guarantee a sequence of events in time. I was imagining blockchain used to capture changes in the probability of events occurring in a time and space independent manner. So the blockchain would store the current answer to the question “in a random universe within a distance of my current universe, what is the percent chance that EVENT occurs”, for a particular EVENT.
Whenever a probability was updated, then it may cause a change in other probabilities. The “proof of work” would be to come up with which probabilities would change the most and the amount of change in these probabilities. Perhaps it would be enough work to just determine whether a probability goes up, down, or stays the same.
The benefit of this over traditional cryptocurrency proof-of-work would be that useful work would be done to continuously update the probabilities stored in the blockchain and this information would be of great value to many people.
One issue would be coming up with the algorithm/system to compute the updated probabilities.
