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.

you're storing information about the users of a web-based application, which is to say that each user has a username that is a string of uppercase letters, lowercase letters, and digits. let's imagine that the most common operations are to add a new user to the application and to check whether a user already exists (given a username). A hash table would be an appropriate way to solve this problem because you know that a well-chosen hash function can lead to something akin to Θ(1) lookups and amortized Θ(1) insertions - suppose that you've chosen a hash function that sums the character codes associated with the characters in the username. Is the chosen hash function a good hash function?

Let us consider a hash table with an underlying array of length 5. It is initially empty, and we then add consecutively the integers: 44, 7, 45, 21, 8, 23, 0, 33 Draw the resulting hashtable after all additions are made. Assume that the hash function used is the remainder of dividing by 5, that is: def hash(d): return d%5 You do not need to consider resizing the underlying array.

The Java hash function for Strings computes a hash code based on a fixed maximum number of characters of the string.

Select all true statements about bloom filters in the box below ：A. If data A was never inserted to bloom filter, it is guaranteed that find(A) returns falseB. If data A was inserted to bloom filter, it is guaranteed that find(A) returns trueC. To detect malicious URLs, bloom filter is in general better than hash table because of its low false positive rate.D. For a fixed size bloom filter, using more hash functions can always help lower false positive rate.E. Assume the bloom filter is using the same hash functions, increasing the size of the bloom filtercan always help lower false positive rate.
