There is no comparable cashless payment platform that leaves no audit trail. Sorry.
Monero is an example of one.
Unlike Bitcoin, a Monero output transaction is crypographically unrelated to its input transaction.
I once spoke to a company who had commissioned... an extrapolation of what the next 10 years would look like in their industry... You can guess what happened over the succeeding 10 years: absolutely nothing... And in fact, 10 years later, the room no longer looks futuristic. Against all odds, its forecasts turned out to be largely accurate. And yet, the company had failed to commercialize even one of the recommendations in the attendant specification document. So I asked the company what they planned to do next; they told me they were going back to the original designers and asking them to forecast the next 10 years! The company blamed their engineers and managers for their failure to commercialize, not the designers.
I personally would love a laptop with a desktop class processor even if it only have a half hour battery life.
The HP Z-book is very expensive, but falls into this category and is well made.
He doesn't have the power to "scrub the web."
He doesn't need to 'scrub the web', he can just 'build a wall' around the offending material to prevent the wrong people from accessing it. "I'm very good at this, it's called construction, it's what I do."
In this case, the construction would be taking a leaf out of Russia's book and enlisting the help of Huawei to build his 'wall' for him.
"We will have this gap of several years without missiles. Well, that's fine if you don't have to fight anybody in the meantime."
Well (speaking as a British Citizen) that's fine by me. Britain doesn't 'have' to fight any wars at the moment. We enter existing conflcts, or initiate conflicts without international mandates based on provably false intelligence.
And of course the UK navy has other ways to destroy ships. Ship-launched TASM (Tomahawk Anti Ship Missiles), ship-launched Spearfish torpedos, helicopter launched Sting Ray torpedos and so on. The last large military vessel to be sunk by our navy was engaged by a nuclear submarine which launched a torpedo (General Belgrano sunk by HMS Conqueror in 1982).
