Hi,

If the blockchain always tells the 'truth' and it's 'impossible' to be hacked because it's a distributed ledger, how is it possible to get hacked? (not counting letting someone have access to your private key).

If my bitcoin is encrypted on the blockchain, and, I'm the only person to have the private key, how is it possible someone else can hack it? My bitcoin is still on the blockchain, right? And I'm the only one with the key!

I've read horror stories on the net about companies going bust (people shitting themsleves when kraken went dark), and reports saying that people could lose bitcoins. How is this possible? The coins are on the blockchain so you can just collect the coins later, with the next, latest and greatest crypto exchange, right? Even if Kraken went bust, pffft.. who cares? Your coins are safe on the blockchain right?

Be interested to hear from the experts..

Hi All,

First post so please be gentle!. I'm trying to get familiar with crypto currency and understand 'how it works'. I've reached a block and I'm hoping someone can shed some light on a particular point.

I understand the process of using public and private keys, back from the time when Phil Zimmermann created PGP. PGP allowed a user to encrypt a file, eg: an email/file (technically, just a bunch of ones and zeros) so that when the other user decrypted the file, they would see the words/file again. Or, to phrase it another way, the encryption was just a 'wrapper' for the content - ie, the words in my email or the file I sent.

Now, if someone sent me a bitcoin, how would I know what I was looking at? With an encrypted email, once decrypted I would be able to see something (text/file) and realise that I had actually received something. But, if someone sent me a bitcoin, what would I be looking at when I decrypted with my private key? A file filled with ones and zeros? Or maybe a simple text file with words inside saying, "Hey, this is 1 bitcoin!"

Can someone shed some light on what it I actually receive when I purchase a bitcoin and how I can verify that what I have 'in my hands', is actually a bitcoin and not just a bunch of ones and zeros? I understand that the blockchain is supposed to verify what is what but, what if I wanted to pass my bitcoin directly to you without the blockchain. Again, how would I know, what I received - was a bitcoin?

Thank you for your time and patience with my lack of understanding!
