Bob offered Alice an X amount of money to complete a job. A hash value of the offer was calculate, the offer was digitally signed by Bob and sent to Alice. At pay time, Alice presented a request for the payment of $100, but Bod claimed that the offer was for $50. He presented a copy of the offer with a hashed value that confirms the $50, but Alice presented a different hash value that shows a $100 pay. How would you determine if Bob changed the offer and calculated a matching hash value or Alice change the offer, and calculated a matching hash value?

Fundamentals of blockchaining

In a business network, the tracking assets and the process of recording transactions are facilitated by the shared immutable ledger called a blockchain. Assets are of two types they are tangible and intangible. The tangible assets are land, house, cash, etc. The intangible assets are copyrights, branding, properties patterns, intellectual property, etc. On a blockchain network, anything that has a value can be tracked and it can be traded.
