OwlFancier posted:Well it's a good thing that we'll have fusion power and quantum computers by then to solve the processing power issues. If it's a private network, an early 90s computer has enough power to process ~~the blockchain~~ If it's a public network, the algorithm is designed to scale the difficulty so that each block takes about 10 minutes. So quantum computing and fusion power would not solve the power issues for more than 2016 blocks, after which it would scale the difficulty up to a level where a block will take about 10 minutes to solve. (assuming the quantum computer does not break the underlying cryptographic technology fundamentally, but then you have bigger worries, like encryption in general)

This is imo a very revealing page https://bitcoinwisdom.com/bitcoin/difficulty The current difficulty is 194,254,820,283. It went up by 8.73% on May 11. The change in difficulty was 15,595,562,510. If you scroll down to the bottom of the list, you can find that the difficulty was 19,729,645,941 in Aug 08 2014. The changes in difficulty are as big as the total difficulty was less than two years ago. Actually, that is a surprisingly long time, speaking as someone who has followed bitcoin more than anyone should. It used to be less than a year.

I don't own any bitcoin or anything but it doesn't seem like there's really a much better way of storing chains of transactions, unless you're talking about getting rid of the peer to peer aspect. A buttchain without the peer-to-peer aspect is just a ledger that you don't delete stuff from. WarpedLichen posted:What is causing transactions to be so slow? Is it just the computational time required to generate the proof of work, which seems like it should be adjustable, or is it because there are enough competing chains that rewinds are happening a lot?

If someone was mining buttcoins with a reasonably powerful desktop in late 2012 or early 2013 for shits and giggles, what would be the expected rate? Well, if someone got bitcoin from that time, the value is now 5-50 times more than it was back then unless they got them right at the end of 13 as the price peaked. If you're talking about the difficulty back then, according to The wayback machine, it was around 1 million in January 2012 and 150 million in in September 2013. As opposed to 200000 million as it is now. I'm pretty sure mining at home was barely worth it back then especially when the price kept going up up up, but exchanging your bitcoins to actual money might have been a problem. The way mining works is if you get lucky and find the next block, you receive 25 bitcoins. At current exchange rate that's about Also in 2016, your computer is competing against Chinese warehouses full of specialized hardware:

If you're part of a pool and someone in the pool gets lucky, you get some fraction of that based on your hashrate. Bitcoins are at $400 not $40k.

It's from the point of view that assuming a crash does happen, how do you minimise the damage? Not saying that particular idea is good way to do it, but assuming some idea along those lines can be made to work reliably it would be good to have. Regardless of whether the car is being driven by a human or computer.

The Larch posted:Can't you patent just about any idea, no matter how stupid or impossible? No. It's actually quite hard to find a concise summary of "what is patentable", but I'll try, using US patent law as a guide: Perpetual motion machines are explicitly banned. A patentable invention must be novel, at least in part; non-obvious; useful (provides some identifiable benefit and is capable of use), and must be patentable subject matter. Those last few requirements are actually not easy to beat, since non-obvious is "not obvious to someone familiar with the state of the art". I'll warn that I'm not a lawyer, let alone a patent lawyer.
