Many benefits in voting? Like once you figure out who is who, everybody can know for whom everybody voted?
1) Not all voting needs privacy 2) For stronger privacy, I would look into reading more about; a) Xpub, Ypub and Zpub and UTXO b) Mimblewimble c) Monero and PIVC

What even surprising is lots of HNers are really strongly against blockchain projects while YCombinator themselves have invested in several blockchain projects[1] [1] https://www.ycombinator.com/companies?query=cryptocurrency
Interestingly, all of those either use cryptocurrencies as an investment, or merely provide cryptocurrency-based tools (of questionable utility), and leave the problem-solving to their users. Why mine (fool's) gold when you can sell shovels?
I'm really surprised by how uneducated most of HN are about blockchain. This means we're still early. Few big things that are coming out of blockchain; 1) ICO - a way to raise money in a distributed manner outside the traditional financial system (think Banks and VCs). 2) Defi - a way to borrow and lend (and much more) outside the traditional financial system. One example, Banks get as much as 16-20% return on your d…
Pretty presumptuous to assume that we are “uneducated” about blockchain to be dismissive of it, rather than being educated but simply believing that the conditions required for blockchain solutions to be better (for a given utility function) than centralized solutions are actually very rarely found in real-life combinations of scenarios and utility functions. Like reversible transactions: I love that transactions are…
Saifedean Ammous writes pretty convincingly how a fixed money supply would be a good thing. I don’t know of any other unique benefit. It will be interesting to see how it plays out with nation states and diminishing block rewards. I’m holding a little bit just in case.
Here's a problem that blockchain solves - financial censorship. If you want to buy a 4chan pass, you'll find there is no option to pay in EUR or USD. Cryptocurrency only. Is this because 4chan is operating an illegal business? No. It's because they cannot process payments using the traditional means. Controversial websites get financially censored all the time. Here are a few that come to mind: Kiwi Farms, Wikileaks,…
It's been a good solution for authentic digital arts! Check out https://knownorigin.io/ https://superrare.co/ There are also virtual worlds to see the art in https://www.cryptovoxels.com/
Yay, we can reproduce the worst part of physical art on the internet now... art is interesting because it's art, not because rich people can speculate on it. In an ideal world everyone could have a Monet on their wall. With digital art, that's possible. Why the heck do we want to change that?
Been a while since a denialist article appeared here. It is in stark contrasts with governments, nasdaq,banks, people using etc and many others. But hey the right to say computers are worthless is always there

> BC solves a problem there because operating a database for that scale would be very complicated. Would it, though? Google tells me that India has a population of around 1.4 billion people. Let's assume each person has one phone number, and each phone number requires one kilobyte of number-mobility-related data. Then the database would need to store 1.4 terabytes of information. 1.4 terabytes doesn't seem like an im…
I don't think it is the size that is the problem. I imagine it is like a routing table, keeping track which number is managed by which operator, and if India has number portability, there needs to be a transactional method to update it that is shared by all operators. I could imagine this being done with a blockchain. Or for that matter, recording of call details for billing between operators?
It must be nice living somewhere where you can trust banks

Number mobility between Indian telecoms runs on private blockchain. AFAIK it is live and actively used. BC solves a problem there because operating a database for that scale would be very complicated. So every telco has their own copy that get synced via a consensus mechanism and signed transactions
> private blockchain So a database? > AFAIK it is live and actively used. Most things people seem to think are running on blockchain tech turn out not to be, so I'd be interested in any evidence here. Nonetheless. > operating a database for that scale would be very complicated They're already operating a database, so at most this is an argument that a traditional database tech wouldn't work, except... ...this is only…
But if you consider it more like an easy to cluster database with free, tamper-proof backups, it makes a lot more sense.
