Being a general ledger, the Blockchain also can be used as a more professional way of proving you made a prediction at a certain time. Sure, as an individual, I can tweet where I think the P/E of Amazon will be in a year and refer back to it to prove my point, but is that the best way for a financial institution? Having an entry in the blockchain has a more business oriented feel to it.
- spullara 10y agoNeither one of these is compelling to me as you have to prove that this was the only prediction you made and you aren't cherry picking the correct ones.

- spullara 10y agoGoes back to an old stock prediction scam. You choose 1024 and send 512 the prediction that a stock will go up and 512 the prediction that the same stock will go down. Each day you repeat this process only with the group where you were right. So, 512 -> 256 -> 128 -> 64 -> 32. Eventually you have a small number of people that think you can predict the future and you can ask them for money that you will invest on their behalf.
- twblalock 10y agoThis also happens in the sports betting world. People use this method to convince others that they can consistently predict the outcome of games, or the spread, or the other stuff people want to bet on.

- amalcon 10y agoPreventing one individual from making multiple predictions doesn't necessarily solve this problem. You can do the same thing by getting 1024 people together to make a variety of predictions. At the end, one person looks prescient.
- baddox 10y agoIt's not clear to me how any system (other than education, which is obviously a very different topic) can solve the gullibility of people who are uneducated about basic game theory and common scams.
- jsprogrammer 10y agoThey'd also need (to become compelling) to prove why one should care that they tweeted a P/E prediction a year ago that turned out to be right.
