I'm shocked and disheartened by how infrequently environmental concerns are brought up when discussing crypto. Proof of Work vs Proof of Stake, security, storage size - these are problems for the network and those that want to see it become a real part of our economy. (I am one of those) But the amount of energy being used to mine bitcoin is a real problem - it's not just a technical challenge (like the problems abov…

A predetermined monetary policy would be great when a financial crisis or credit crunch hit, causing a collapse in the velocity of money /s While I have invested in crypto and believe it has great potential, one of its touted benefits by its supporters is also one of its biggest pitfalls, namely that its money supply is predetermined. The inability to actively manage a money supply given exogenous shocks to the econo…
I think it makes sense. You have an economy built on an economic model rather than an economic model based on an economy. With the latter you're constantly guessing and tweaking the model and roughly every 10 years there's a crash and the economists say okay, NOW we have it perfect and we'll never get it wrong again. Why do you need an unlimited money supply? The only thing causing these shocks is that the economy is…
Re: A faster, more efficient cryptocurrency
#253This gets asked often, but in case something changed recently - what are the use cases of cryptocurrencies that are not: - Attempts to side-step the law (however misguided the law is) - Trivial to do using a typical centralized database (e.g. Federal Reserver or VISA) - Tantamount to waiting for a greater fool to buy out the current players I am not looking for answers of the form "well whenever you want to avoid a t…
Cryptocurrencies are definitely an “Innovator’s Dilema” situation when it comes to general use. It’s much worse than the established solutions. It’s confusing, error-prone, unreliable, cheap and janky. It’s also not a great business case for the establishment who are currently making billions and billions serving very rich customers. But... it also brings financial service options to people who have no opinions or on…
I think I can buy that. The unbanked could become centrally-banked like all of us as their countries develop, but there is a competition between that and the cryptocurrency which could wedge itself in at this point and outcompete the local government simply because the government is small and lacks in experience (maybe corrupt too). Another contender here is WeChat and similar centralized payment technologies, but they too are hamstrung by their own current governments (I'm sure that Payapal is) giving breathing room to competition.
It is not obvious to me which one of the three will win among the unbanked.

I think you are conflating bad with unjustified. They aren’t the same but can appear similarly themed. HN is skeptical of the utility and validity of crypto.
That's what I thought too! But no - HN is against crypto at the moral level. One day the almighty father Paul Krugman declared crypto as thought-crime, and ever since, progressives have dutifully towed that line. It's tiring . I think they subconsciously see it as an attack on state-sovereignty or something like that. The ability to tax and redistribute. That's just me reading between the lines.

#255Hadn't heard of vault or Algorand before, but woah, what a team of heavy hitters: Micali, Goldwasser, Andrew Lo, Kenneth Rogoff, Herlihy etc. basically a who's who in CS, Cryptography, Econ & finance. If any group will do crypto right then at least on paper it would look like this team

I want a cryptocurrency which is egalitarian - evenly distributed among people in the world, rather than one in which a few people own the majority and profit hugely.
Yes! And I think there is one aspect of Bitcoin that is precisely backwards in relation to both this and the energy crisis: proof of work is a substitute for proof of identity so it can be anonymous. Imagine a currency that everyone is born with a certain amount of, with the only price of admission your ability to prove your identity. Suddenly, we have solved the problem of proof of work for allowing this to be a dis…
Would that be a new age of fairness?
