I personally found that with rigorous enough usage, I don't even miss having actual static typing anymore ;)
1) they show total cases including recoveries and deaths by default, bumping up countries like China
2) they sort by total cases which pushes high population countries high
The info I'm looking for is generally "how bad is it everywhere, right now". So I spent a couple evenings to hook into the Bing dashboard and create this minimalist breakdown off of it. Comments welcome!
"As pointed out before, giving rewards for creating blocks creates an arms race in computing power. Transaction fees only magnify the effect. This is very healthy for the security of our system — anyone can add blocks, so anyone can do it according to their own agenda, but to have any kind of significant effect on the whole thing they would have to invest a tremendous amount of resources.
Remember, the only way to determine which version of the transaction history is the commonly accepted one to look for the longest one. In theory, someone possessing 51% of the computing power of the network is able to completely control the system, as they can just start their own branch of the blockchain and create new blocks faster than anyone else. The resulting branch will become the longest and therefore accepted one, invalidating any blocks mined on other branches. Performing the 51% attack is however uneconomical even for actors the size of a government or a multinational corporation — it would simply cost too much for the trouble."
To give you some numbers, an Antminer S9 costs $3k and provides 14 TH/s. Current Bitcoin network hashrate is around 7,700,000 TH/s. Assuming a 51% attack is not underway already, an attacker needs to have at least the same hashrate as the rest of the network. This would cost over 1,5 billion dollars in non-reusable single purpose hardware alone. Add to this the ginormous power costs and additional costs of housing, maintenance, cabling etc. and you start to get the idea.
A sizeable entity who doesn't have complete majority can still make life harder for users by censoring specific transactions (simply deliberately choosing not to include them in their blocks), but this is more akin to a DDoS attack than a security breach.
You're right, I didn't describe the details of networking. My main goal was to keep it as short as possible while still explaining the main "pillars" of Bitcoin in detail, and networking did not make the cut. As far as my understanding goes, there isn't anything inherent to Bitcoin in the way its network works (it could apply to most other distributed networks), so I thought including this would stretch things too much and stray too far off topic in a way.
Making so many errors in a sentence about basic language features, when a big chunk of OP's article is argumenting that React Native is bad because JavaScript is bad... Maybe it would be less bad if OP actually learned the language?
