For people that are new to blockchain: I noticed that Ivan uses the short form ‘PK’ for ‘private key’. However, when using ‘PK’ for ‘private key’ we run into an issue: ‘PK’ can also stand for ‘public key’. Therefore, it is much better to use ‘SK’ for the short form of ‘private key’ because a private key can also be called a ‘secret key’.
SK = secret key, also known as private key
PK = public key
I think he’s referring to PK Subban, the hockey player 
I understand the difference with Public keys and Private keys.
Like having a garage door opener for everyone to used but you have the pad control number to control the doors access.
Except you can’t accidentally crash your car into your public key 
Good analogy though!
My guess is the Garage door analogy isn’t the best but, if I got my idea across, mission accomplish.
Hahahaha nailed it 
Yes i think its would be a good idea. Well thought Sir thanks for the content
