Imagine and equivalent amount of computer power in an alternative future. I mean, you're right, and this limitation is a flaw in bitcoin, but you've also missed the point.

No, I'm imagining, and I'm sure we'll get there eventually, but BTC has a lot of inertia at present.

It's also hard to call it a flaw in Bitcoin, considering it was an intentional design decision.

Even intentional design decisions can be flawed.

There's a pretty hard limit bounding the optimizability of SHA256. That's why hashcash uses a cryptographic hash function.

There may be - or, very likely are - shortcuts for proof of research better than Grover's; which, when found, will also be very useful for science and medicine. However, that advantage is theoretically destabilizing for a distributed consensus network; which is also a strange conflict in incentives.

Sort of like buying "buy gold" commercials when the market was heading into the worst recession since the Great Depression.

SSL accelerators may benefit from the SHA256 ASIC optimizations incentivized by the bitcoin design.

"""The accelerator provides the RSA public-key algorithm, several widely used symmetric-key algorithms, cryptographic hash functions, and a cryptographically secure pseudo-random number generator"""

GPU prices are also lower now; probably due to demand pulling volume. The TPS (transactions per second) rate is doing much better these days.

How would you solve the local daretime problem in order with Git and signatures?
