STEEMCRYPTOACADEMY SEASON3/WEEK4/ HOME-WORK POST FOR PELON53
Explain in detail the hash rate
Hash-rate can be used to accessing the strength of a block-chain network, to be specific the security of the blockchain, with my all-round accessment I came to realize that blockchain can't work without hashes and blocks, the more different machines used torolly assists different miners to know their next block it will be very hard for the network to be disrupted because the higher the hash-rate the greather it becomes difficult for hackers to gain access.
No matter how deplomatic hackers can be it's very different to access blockchain hashes simple because blockchain seems to be very deligent and it has a system at which it operates this particular one is called longest chain rule groups of individual who are saddled with the responsibility of controlling enough hash-rate can block and notify a transaction in this process reversal is very much possible.
So many up and downs will come to fruition thereby bringing the efficacy of the blockchain to disreput, if a hash-rate is reduced the the blockchain will be in trouble because along the process it will be very vonurable.
Hash-rate FAQs
We have some acronyms which stands for different things for example we have the 89 EH/s, this signifies exahashes in a single seconds this means that we have quiltillions hashes in a single seconds, this signifies that miner's accumulates quiltillions of hashes in a single seconds, this is massive.
Make the following Merkle Tree:
Transaction (tree leaves): Steem1; Steem2; Steem3; Steem4; Steem5; Steem6; Steem7; Steem8.
I made it to the Root Hash. And put every hash generated using SHA-256 , show screenshots.

Tell the steps to follow to verify if Steem6 is included in the Merkle Tree
Here I weill generate in the Markle Tree is the higher branches making use of Steem1, Steem2, Steem3

Here I will generate the Markle tree, I will generate the Root Hash also known as the Merkle root
Hash

In this phase now you can combine the root hashes together, the second level branches too, the branches and leaves will thus create our Merkle Tree
Using the SHA-256; 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.
Here what we will do first is to generate Merkle tree leaves.

At this phase I will generate the root hash of the Merkel Tree
Hash
CB40CA6DB72DD507CF9118963F94B7740822258E74AFB0FD45D89DB35D24B386
creating the Merkel Tree is possible now what we should do now is to sum up the various hashes we have officially created, from the ones I have been creating I'm sure you see the hashes clearly
If the number of leaves on the tree is odd, what should you do? Explain.
If the number of the leaves on the trees appears to be odd it will be very difficult to calculate the root hash since it is divided in such a way that it appears to be even whether you are looking for the root hash, or the parent hash for me what should be done here is to create another branch that will be equivalent to making sure that the parent/root hash is balanced
Let's say for example you are asked to generate a root hash of SCA1;SCA2;SCA3;SCA4;SCA5. This particular one is odd so what you need to do is to add SCA5; again in order to balance up since it must be even
Conclusion
From my assignment you will understand that Hash-rate is basically used to access the strength of blockchain network and security, blockchain itself cannot operate or function without blocks
It will be very difficult for blockchain to be disrupted because the higher the hash-rate the higher it becomes for hackers to gain access to the blockchain
Miners in the blockchain accumulates lots of hashes in a single seconds, quiltillions of hashes within a shorter possible time frame seconds to be precise
Merkle tree constitutes of leaves, hashes, and root hash and it is very simple for it to be generated you can use SHA-256, to generate anything you feel like generating
Many thanks to you professor @pelon53 I really enjoyed your fantastic lecture and I learnt alot hopefully I will explore more of your lectures
