there is no known way to hack a blockchain, but "wallets" can be stolen - there have been several instances where large bitcoin banks have been hacked and lost all their virtual currency. A friend is a bitcoin miner and he uses four computers, with four heavy duty graphics processors - all water cooled to do so. A lot of computing power but still within the budget of an individual - no where near that of a "small country."

'Like blockchain technologies, this information will be write-only...' - funny!

'Blockchain entities like Bitcoin are distributed among lots of different players require a lot of power (computing and literal) to compile and check — as much as a small country,' - Really?

So there's no way to hack a blockchain? Or perhaps I should say why is it so secure?
