>I think, in the next years, we will see more and more of these useful proofs cropping up. And people will understand the value they're "storing", no pun intended. You could be right, but the first time something like this was discussed was around 2010 [1], and here we are 12 years later, still waiting for widespread implementation of a "useful" proof of work. [1] https://primecoin.io/ was the first result of that. - Source: Hacker News / over 1 year ago
One of the first I heard of was Primecoin [0], which still seems to be going along steadily. They've actually uncovered a number of world records [1] looking for Cunningham Chains. [0] https://primecoin.io/ [1] https://primes.zone/#records. - Source: Hacker News / over 2 years ago

The closest we've come to what you might call "useful" proof of work is Primecoin, which searched for chains of prime numbers, to the delight of some mathematicians. But it's pretty much a dead coin now. There are also some coins that appear to have solved it, such as SolarCoin, but look closer and you'll find that they are completely centralised. That's not a trade-off Bitcoin can make. Source: about 3 years ago
(I live in USA) When I go to payments under my shopify account to add paypal as a payment method I am having trouble doing so. I first click activate paypal > activate paypal express checkout which directs me to a "security challenge" (confirm I am not a robot). Then it just brings me to paypals website (paypal.com/us/home). When I sign in nothing happens, I am just on my paypal homescreen. Source: over 1 year ago
