1.- Explain in detail the hash rate.

A cryptographic hash function is a sort of hash function with qualities that make it useful in cryptography, one of which being the ability to create something that prevents third parties from accessing information.

Hashing power and speed are critical components of any PoW-mined cryptocurrency, such as Bitcoin.
Blockchains would not be able to function as distributed ledgers without hashes because decentralized processing power would not be directed to a specific function.

The hash rate refers to how quickly a cryptocurrency mining hardware works. To be effective in mining, you must be quick because the miner is essentially trying out many different solutions to the problem of solving blocks. And the more answers given in a shorter amount of time, the more likely it is that this block will be solved.

The hash rate, also known as hash power, is the number of attempts made to calculate the hash at a given point in time.
A higher ratio is better for mining because it increases the chance of discovering the next block and receiving a reward.

The network's complexity is proportional to its hash rate because as the network's power grows, so does its complexity. This is done in order to maintain the 600-second block creation duration.

2.- 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 Markle Tree.

Here is where to start

Merkle Tree


Tell the steps to follow to verify if Steem6 is included in the Markle Tree.

Steem6 can be verified when it has been completed: We must wait for all of the data from several peers to arrive before we can verify its legitimacy. If there are thousands of peers spread around the globe, the best strategy is to gather all of the data before validating if it is correct or included in the first place.

3.- 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.
If the number of leaves on the tree is odd, what should you do? Explain.

SCA1: 13E0A04BB0E669E1C638DBE3A704743F99F162B25245E4D8C064D35BA38FA8C8

The Merkle Tree Root hash

Merkle Tree


If the number of leaves on the tree is odd, what should you do? Explain.

Every successful, and useful merkle tree works in two piers. They don't work alone, working together in 2 piers is how it can perform what it was designed to do.
But possibly, if things doesn't go as programmed and the leaves is odd, while others has been completed in piers, the last number without piers will hash itself.
The last odd leave will come out in 2 places to fill the blank space and balance the equation.
If the leave equation doesn't balance in even number, the computed algorithm will not function.
One of the reason why it is called merkle "tree" is because it all works jointly together from the leaves down to the root.

If "pelon53" is the last leave and has no pier, and become odd, pelon53 will come in 2 places and hash itself. i.e "pelon53pelon53". Now it has become a pier and in total, the leaves has become even.


Hashing rates are increasing at an exponential rate, as are the ASIC capabilities of miners and users trying to ensure the Cryptocurrency network's security. Best regards to @pelon53 who has taught us a lot
Hash rate critical component of the ecosystem and an issue that every cryptocurrency user, investor, and trader should know and understand how it works.
