To expand on that, mega.co.nz does attempt to do encryption end deduplication. Each file uploaded is encrypted with it's own hash, and the hash is stored in the users encrypted account. The idea is that if two users upload the same fil

Qatar has a huge allocation of unused IP addresses. It's a matter of choice that their censorship proxy only exposes one IP address on the internet side.

If the articles I've read are to be believed, Apple has at least $150B in cash just lying around. Tesla wouldn't be a huge chunk of that if they were so inclined.

Still just minor value changes, no effect on processing transactions.

Dogecoin has no significant changes. The coinbase value is detirministic, the POW is altered slightly and some other values are changed. Nothing interfacing with it needs alterations, other than things with validate blocks and so forth.

Really the only difference between "altcoins" and Bitcoin is the version number in the address, often not even that. "Support" isn't so much needed as incidentally created. Minor fiddling with the POW (often breakin

There's no evidence to suggest any code reuse, much less 7 years later. The card exchange never existed in a usable public form, it's just a page saying to contact them. What code could possibly be reused between the services had

I am, but there's no code to reuse in this situation. Maybe some scraps of user authentication code, all the rest is completely different. What you're describing is like trying to adapt a VW Beatle to tow cruise ships, sure you co

Please explain the similarities in the backend to me. Trading cards is basically an online store, nothing like Bitcoin and nothing like a currency exchange. The similarities begin and end in the name.

That story makes no sense at all. They started developing an exchange for cards in 2007, then somehow modified the system to work with Bitcoin four years later? There's absolutely no similarity between those services. I provided a refe

There's no acceptable middle ground really. Practically every Bitcoin service is full of incompetence of varying degrees. Coinbase for example uses MongoDB for their accounting and apparently was hacked (and the funds returned) as an e
