Bitcoin's blockchain stores financial transactions.
Ethereum's block chain stores smart contracts.
A smart contract can store records on who owns what, it can store a promise to pay & promise to deliver.
It can also automatically move funds in accordance with instructions given long in the past.

You can check the blockchain to find if the house has been sold twice, who owns this land, what happens if the loan defaults etc

	salt = ''.join(x.encode('hex') for x in salt)

	#2.Concatenate that with the UTF-8 representation of the password (in this case "simon")
