What is a “brute-force” attack on a hash function? Describe two types of brute-force attacks Suppose H(m) is a collision-resistant hash function that maps a message of arbitrary bit length into an n-bit hash value. Is it true that, for all messages x, x’ with x ≠ x’, we have H(x) ≠ H(x’)? Explain your answer

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.
