Hello All proofer and students. This is @mousumimou. I read the lecture thoroughly for more than two time and now after getting the points, i am going to do my homework task about Hash Root and Markle for professor @pelon53.
Questions:-1
Hash rate
Hashrate is a proportion of the computational Power each second utilized when mining. All the more just, it is the speed of mining. It is estimated in units of hash which means the number of computations each second can be performed. Machines with a high hash power are exceptionally effective and can handle a great deal of information in a solitary second. BTC, the hashrate demonstrates the occasions hash values are calculated for PoW consistently.As the arrangement reached a hash measure of 10 Th/s, it destined it might brew 10 trillion calculations every second.
Question 2
Make the following Merkle Tree: Transaction (tree leaves): Steem1; Steem2; Steem3; Steem4; Steem5; Steem6; Steem7; Steem8.
To create the Merkle tree, firstly generate the tree leaves hashes.

The next step is creating the tree of the inputs and hashes
Merkle Tree
To make the Merkle tree, first generate the tree leaves hashes.
Tell the steps to follow to verify if Steem6 is included in the Markle Tree.
Source
To verify that Steem6 is included in the root hash for the Merkle tree, the user verifying will need to access the following.
Hash of Steem5
Hash of Steem7Steem
Hash Steem1Steem2Steem3Steem4
Step 1
Calculate the hash of Steem6
Step 2
Since the hash of Steem5 , Compute the hash of Steem5 and Steem6. It will give the hash
Steem5Steem6
Step 3
Since the hash of Steem7Steem8 is known, Compute the hash of Steem5Steem6 and Steem7Steem8.
It will give the hash Steem5Steem6Steem7Steem8
Step 4
As the hash of Steem1Steem2Steem3Steem4
Compute hash of Steem1Steem2Steem3Steem4 and Steem5Steem6Steem7Steem8
It will give the Merkle root hash
Steem1Steem2Steem3Steem4Steem5Steem6Steem7Steem8
3.https://passwordsgenerator.net/sha256-hash-generator/ you must place each complete hash in the Merkle Tree.Transaction (tree leaves): SCA1; SCA2; SCA3; SCA4; SCA5; SCA6; SCA7; SCA8. Explain each step, show screenshots.

If the number of leaves on the tree is odd, what should you do? Explain.
If the number of leaves on the Merkel Tree is odd we will not be able to compute the root hash reason it was decorated in a system to be compute in even numbers(2,4,6). as such the end leaf should be uncertain in other to become a master hash to engaged other branches
The tree above have seven leaves, so we should be uncertain the ends leaf by marking another SCA7 which is then submerged with SCA7 to get SCA7SCA7 as its main hash and from here we can proceed to the highe step branches as well as root hash.
Conclusion
We know that a hash is a alphanumeric code of fixed length that is generated by turn into any data to have is ambiguous .Merkle tree is a data processing that remaina all the hash codes for the transactions that are express throughout block. Hash system is totally strong and reliable. We user use this security system than fell secured. This lessons it too much important for everyone tader..
