So in short, a price feed from several crypto exchanges. Thanks!

So far, I have a 20-minute video that is clearly mostly not about the Dai peg, and a link to a very wordy "paper". I skimmed both, and the answer is apparently "oracles", or a price feed from several crypto exchanges. Th

What's the most I could send without network liquidity issues?

That doesn't explain how it's pegged to the dollar.

It's less usable than it's parent blockchain!

How much collateral do you need for an asset that is as volatile as a cryptocurrency?
458.
by ppf 7y ago
And how is it pegged? Someone asked the various exchanges very nicely if they could only trade it for $1?

>Earning interest He's talking about "DeFi" ("distributed finance") - the current craze in the Ethereum world. Various groups are offering significant interest rates for loaning out your Eth. It's hard to se

> my friend sent me $300 > Oh wait, now it's $310 > Damn, now it's $200 The other downside, as you mention, is that the only main use for Eth is speculating on experimental lending platforms.

Even better! Let's deforest huge areas of virgin forest for crappy vegetable oil plantations, and then fill our own air with particulates that are awful for anything with lungs.

Indeed. I hope the climate activists are taking this opportunity to learn about human behaviour once a situation is deemed an emergency - everyone will do whatever it takes, whether it's run a cheap (and, I assume, highly polluting) IC

Wonderful. What would energy usage and air pollution look like if everyone did this? Decentralized energy production = horribly inefficient.

California, leading the world in climate change activism, as its residents rush out to buy cheap generators and idle their cars to get power. Yay!

You'd need a few machine shop tools to make your own generator, as well as access to magnets and other specific materials (iron laminations, etc), as well as a good understanding of magnetics. I think you underestimate what 'world

Out of interest, how would you do this, and how much power do you expect to generate?

It's not an accident ;-)

Your first paragraph was on-point. I'm talking about the second one: > I too have qualms with what is going on in China, but like everything that happens in this life, I’m flipping petrified of how much damage some reactionary ameri

Fine, but don't pretend you care about human rights in any context.

China accepts child labour, and runs ethnic concentration camps. Have you forgotten that standing up for what is right can result in negative personal consequences? Or have Americans gotten so used to consequence-free "protesting"

Not my point, and an electric motor isn't going to do much without a battery.

How would you describe the npm install process?

Also, with a higher cost to manufacture these energy sources, it's inevitable that the cost to consumers will rise.

Your figure of 15W/sq foot assumes no gaps between panels - hard to imagine on a 50mile+ array. The bigger problem is that it assumes overhead, direct sunlight. You'd have to cut that at least in half ;) Yes, the UK does have issu
