Ristretto adds complexity over just using secp256k1, which also has very good Rust support, is quite fast and well-optimized, compiles to WASM, and supports ECDSA, ECDH, and Schnorr key aggregation, so it's quite full-featured.
Funny timing that this particular topic made it to HN. From the recently-released Season 4 of The Dragon Prince, this is one of the reasons Claudia is so infatuated with Terry, an Earthblood elf.
If the unit cost is higher than the maximum a manufacturer or retailer can charge, it won't be produced at all. This results in a market failure, similar to the one China's experiencing with their energy market, where the price of coal is 4x what it was earlier this year.
Seems to be trending downward... Who knows if it'll be enough.
I was curious if a similar downward trend existed for solar panels...
"In 1956, solar panels cost roughly $300 per watt. By 1975, that figure had dropped to just over $100 a watt. Today, a solar panel can cost as little as $0.50 a watt."
So, that's a factor of 600 to get to present costs. Gold currently costs $56,500 per kg. So, $33,900,000/kg. So, who knows where we could be in 50-70 years. Plenty of time to switch the entire global economy to Bitcoin, I suppose!
> "Builders still have to clear their inventories of having purchased higher-priced lumber. It takes a while to clear the system," Lee said. "Yes, lumber prices from the mills came down dramatically over the summer, but that's unfortunately taken a while to reach the rest of the industry and consumers."
> Lee said when it comes to new home construction, pricing is being complicated by ongoing pandemic-related supply chain challenges. While difficulties related to lumber have eased, home builders are still dealing with delivery delays and price inflation on everything from plumbing and electrical products to kitchen cabinetry.
> "It doesn't compare to the three to five times price increases we saw with lumber, but I'd say on average, we're seeing 10 per cent increases on everything, including the kitchen sink," Lee said. "And we are still seeing delays on closings, just because of an inability to get products and materials."
Meanwhile... August 27th, 2021:

Agreed, I wish we'd have gone down that road. How is it more efficient for my signals to go a thousand miles away and back just to talk to my neighbor across the street?
I've often thought, the web isn't designed for efficiency, it's designed for scale. Scale around big tech giants, to concentrate wealth, exploit gray areas, and magnify harm.
I used to love JavaScript, but when I look at what it's become, I'm glad I left it. We weren't doing the world any favors by contributing to a massive body of casual execution of untrusted code.
The web was a mistake, but I think the internet, good old TCP/IP, still has a few tricks up its sleeve for us yet.
