I would agree except for the Antlions. Infuriating gameplay.

A hash of a phone number or IP address would be trivial to reverse.

I imagine under the sea is actually quite a nice place to be, if you assume perfect waterproofing. There's litte radiation penetrating the water, so there's less chance of bit flips I imagine. You don't need to worry so much

Spacecraft and rovers use ridiculously armoured, redundant systems to get past the fact that they would fail quite regularly in such a hostile environment. The Curiosity rover in 2001 uses what would normally be quite an outdated 132Mhz CPU

That's right. You have to keep broadcasting it though, the transaction won't be retained in the nodes storage for a long period of time.

You can do a trick where you make a transaction from a private key with a nLockTime set in the future, then not broadcast it until that date, and destroy the original private hey. Then the only option is to wait until the time or block numb

A Block Eruptor ASIC (BE100) uses 10W/GH/s, a newer chip like Bitfury uses 0.9W/GW/s, the Block Eruptor 2 chip uses less than 0.2W/GH/s. It's decreasing rapidly.

More than that, it's things like "free to play" also sucking the will out of the consumer.

You asked why mining was necessary. I provided an explanation.

Confirmations are just a measure of computing power essentially. By saying a transaction needs 3 confirmations you are saying that you require 30 minutes of network hashing time before you call a transaction secure. For the same 30 minutes

A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefit

Litecoin does not solve any problem, just the proof of work algorithm is changed. The block time has nothing to do with it really, it just makes people believe one confirmation is as strong as any other (Litecoin's are actually just 4

A cryptocurrency based on CPUs is just fodder for Botnet herders, like Bitcoin was for quite a period. Amusingly, that was Litecoins original call to action, "GPUs are too centralised, we can only be CPU mined!", except that they

Yep. There's absolutely no risk for a vendor setting prices like this.

In short: misunderstanding ECDSA, or just writing a bad implementation, revealing their private key by signing twice with the same r value (it should have been random).

Doubtful. The balance was never 39,917BTC, it's been dropping funds in and out for almost a month now. If it was stolen, they took their time doing it.

.io is a generic TLD in most books now anyway. There's lots of other ccTLD that are fairly useless, though it's obvious why ones like .co.ck (the uninhabited Cook Islands) were never picked up as generics.
