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.

Given a hash table of size M=10 and a linear probing method, following are the contents of the hash table: [-1, 41, 71, -1, 64, 75, 84, -1, 88, 9]. -1 indicates slot is empty. Use the standard hash function: h(x)=x%M Match the index on the left with the value on the right for the hash table after the following operations are carried out in the given order: delete(88) delete(41) delete(44) insert(108) insert(71)
code in python attached please Define a hash table with an associated hash function ℎ(?)h(k) mapping keys ?k to their associated hash value. b) In simple uniform hashing, each key is assumed to have equal probability to map to any of the hashes in a given table of size m. Given an open-address table of size 500500 and 22 random keys, what is the probability that they hash to the same value? What is the probability that they hash to different values?
Lottery with Hash commitments. We have 3 parties in a lottery where one of them will be the winner. Assume X chooses 58906, Y chooses 79654702, and Z chooses 2578012. Each computes the SHA-256 hash of their chosen number. They publish their hashes first; then they publish their random numbers; the winner is the one: (H(X) XOR H(Y) XOR H(Z) mod 3. X is the winner if the final value is 0; Y is the winner if it is 1; and Z is the winner if it is 2. Compute the steps and show each step; and show the final winner.
Given:• a hash function: h(x) = | 3x + 1 | mod M• bucket array of capacity 'N'• set of objects with the folloeing keys: 12, 44, 13, 88, 23, 94, 11, 39, 20, 16, 5 (to input from left to right) 1. What would be the hash table where M=N=11 and collisions are taken care of using linear probing? 2. What would be the hash table where M=N=11 and collisions are taken care of using separate chaining? 3. Would a size N for the bucket array be able to exist, so that no collisions happen with thehash function h(x) = | 2x + 5 | mod 11 and the keys above?
Computer Science (a) Let h be a collision resistant hash function. Now consider the following function H that is defined for binary strings of even length. Let x = x1||x2 with x1 ∈ F2n and x2 ∈ Fn2 . Then H(x) = h(x1 ⊕ x2). Prove that this function is not collision resistant.
Consider a hash table (hash function and hashing scheme) and its maincharacteristics.Which of the following is FALSE ?O A hash function's output is deterministic.O Linear Probe Hashing is the most basic hash function.O A hash table provides on average O(1) operation complexity.O A hashing scheme handles key collisions after hashing.
Let S be the set consisting of all 10 digits and all upper- and lowercase letters. Let U be the set of all (ordered) strings consisting of exactly four elements from S. Construct an injective hash function h: U -> N with the smallest possible value of maxUh(u). Modify your hash function to give a simply uniform map h' to the set {0, ..., 30}. In other words, if U is a probability space with P(u) = P(u') for all u, u' in U, then the random variable h': U -> {0, ..., 30} should have a uniform distribution..
Computing Values of a Hash FunctionInstead of 10,000 students, suppose there are only 6. Define a functionH, from the set of student ID numbers to the set {0, 1, 2, 3, 4, 5, 6,7, 8, 9, 10} as follows:H(n) = n mod 11 for each ID number n.To compute values of H either use a calculator or a computer with abuilt-in mod function or use the formula n mod 11 = n - (n div 11). Inother words, divide n by 11, multiply the integer part of the resultby 11, and subtract that number from n.As an example, since 328343419/11 = 29849401.73.H(328343419) = 328343419 - (11 * 29849401) = 8. To store the link tothe record for the student with ID number n, start by computing H(n).For instance, if the ID numbers are 328343419, 356633102, 223799061,607275830 and 513408716, calculate the hash values and comment in detailwith mathematical justification on the hash function.

For example, if you are hashing the key 2476, then h(2476) = (2 + 6) % 8 = 0 Assume that collision resolution is done by linear probing. In what slot will 1000 be placed? Provide only the index of the slot.

Given the input set A = {1, 2, 3, 4, 5} and output set B = {1, 2, 3, 4}, is it possible to find a hash function H from A to B that has no hash collision, i.e., LaTeX: \forall ∀ a1, a2 LaTeX: \in ∈A, H(a1) LaTeX: \ne ≠H(a2) If yes, please give the function. Otherwise, please explain. (Hint: pigeonhole principle)
A linear probing hash table of length 10 uses the hash function h(x) = x mod 10 + 1. mod is the reminder operator. For example the h(42) = 42 mod 10 + 1 = 2 + 1 = 3 so we insert 42 in the position 3 in the array. After inserting 6 integer keys into an initially empty hash table, the array of keys is…
