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.

4 Suppose an adversary uses brute-force to attack hash functions. For a general hash function with m-bit hash value, how many times on average should an adversary try to find the preimage of a given hash value? How many times on average should an adversary try to find two preimages that generate the same hash value?
