1.- Explain in detail the PoH of Solana.

Solana is a web scale Blockchain which provides a very fast, scalable, secured and Decentralized Dapps . It can scale hundreds of thousands of transactions per second and It has a block time of 400 milliseconds. They can handle over 710,000 transaction per seconds. Solana network is relatively fast and cheaper because it's consensus mechanism don't actually use PoW, instead it combine both PoS and PoH in other for the system to function properly and accurately.

Now, the PoH(proof Of history) enables the Blockchain to work relatively faster while maintaining security and Decentralization. For instant, if snapshot of diffusion were scrambled, we will know how to place the resulting emergence in order again because of alot of entries as a function of time. So here we see that PoH uses a recursive verifiable delay Function to hash incoming events and transactions.

All the event have a unit cash and count along the static structure as a Function of real time and this information will always tell us what type of event had to come before another just like in a Cryptographic timestamp that gives us a verifiable ordering of events as a function of real time. Each node have a Cryptographic clock that will enable the network to agree on time and ordering of events without having to wait to hear from other nodes unlike slower traditional Blockchains that can't perform this because they they do not have a PoH. Solana always achiev high true podes without sacrificing network security and it has 25blocks being validated by 25 people at once. This validators can actually run different types of smart contracts code in a parallel way at a Sealevel. For insurance, a computer will be able to perform different types of task simultaneously at the same time interval rather than performing one task before moving to the next.

2.- Explain at least 2 cases of use of Solana.

Solana can be use as a project in so many ways. I will give some of it's project uses below 👇

1) us as Maps.me

Screenshot from maps.me website

Maps.me is one of the best projects on Solana because it's a mobile application which give users an OpenstreetMap data on an offline map since many people often use the app when they are traveling. It will soon become a Crypto wallet in a situation that will be able to accommodate booking, asset management, fund transfers and payments when ever a user of the maps.me is traveling because of its integrated DeFi features. More than 140 million people uses this app across the world

2) Use as Raydium

Screenshot from Radium website

Raydium gives an On-chain liquidity and it is an automated market Maker that is firm to a Solana blockchain. It resently Launched a project, Fusion Pools, both stakers and liquidity providers can receive a double yield rewards from this Fusion Pool and. The Raydium protocol has gotten attention and interest as it's total value lock (TVL) has recently gone over $700 million market. The On-chain of Radium have a pool that have access to a liquidity on serum and the other flow

3.- Detail and explain the SOLA token.

screenshot from coinmarketcap

From the screenshot above, current Sola Token (SOL) price is $138.51. The Sola Token (SOL) marketcap is $41,091,150,757. The SOLA token is regarded as the next generation of Decentralized social platform which generally control by its users as they earn, spread and create all of their details in a good transparent manna. It offers its Users IDO launch, bootstrap liquidity and easy fundings

SOLA token is rank amongst the top 10 highest token and it's transaction is extremely very cheap and very fast because it's transaction can cost just about $0.001 USD. It was brought into existence last year with an initial value of approximately $0.7. in less than no time, it's value have rapidly increase and it stands at $138.51 at the coinmarketcap which is the current value at which I did this post. From this great increase just within a year we can see why the SOLA token is regarded as one of the best tokens so far.

screenshot from solscan.io

After exploring this site, we see that SOLA token has a Market price of $0.060879, A fully Dilluted Market Cap of $1,653,052.23 and a maximum silly of 27,153,077.98

As of now, the SOLA token already have about 1,902 wallets from 1,902 people and they can trade the token using a DEX application with a pair of SOLA/USDC

Before trading on the token, they stake the token into their wallets Iike ledger nano X and hold in other to gain profit when it rises, or they can decide to create a stake account, select a validator and then Delegate the stake

4.- When did Solana Blockchain see its operations interrupted? Why? Explain.

Solana Blockchain saw it's operation interruption last Tuesday 20-09-2021 and this interruption was as a result of a native token(SOL) which was exhausted because the load of the transaction was about 400,000 transaction per seconds. However, the speculation gain rose from $1.86 on January 2021 to about $171 last Tuesday when the disruption occur. This crash lasted just for approximately 17hours by keeping over $11 billion investors' money.

This crash occurred at about 12:00 UTC when a grape protocol had launched an IDO on the generation of bots transactions that flooded on the network at that time and on Raydium. Many validators had to crash due to overflow of the memory as a result of the creation of transactions of network which had to eventually slow down and become stall. As a result of this transaction slowdown, the network had to go offline as the validator network couldn't longer agree with the blockchain current state hence not allowing new Blocks to accept the network. Due to this interruption, SOL price drop drastically from $171.48 to $142.86 which is approximately 5.06%

5.- Check the last block generated in Solana and make an approximate calculation of How many blocks per second have been generated in Solana, taking into account from the initial block to the current one? Justify your answer and show screenshots.

I will be performing this task by logging into Solscan

screenshot from solscan.io

We can see from the screenshot above that the last block is # 98726446

screenshot from solscan.io/book

We can see clearly that the first block of Solana didn't register any timestamp

Let's calculate How many blocks per second have been generated in this Solana

We have to take into consideration that each block always generate every 0.5seconds approximately from the block information project.

Now let me multiply this 0.5sec to the total number of blocks at the time of my post

[0.5sec * 98726446] = 49,363,223secons

If we want to calculate the seconds to years

screenshot from google

The seconds into years gave us 1.5642261452 from our calculation on google. So we can assume here that it is approximately 18 months, that's almost getting to 2years. Now If we take the current date and subtract it to this 18months, we see that it will move us to the official month of which this network was launched which was March 2020

After doing all this calculations, we can now assume that 1 block Always generates approximately every 0.5seconds on the Solana blockchain

Conclusion

After going through Professor @pelon53's lessons and carrying out futher research, I have discovered that the Solana blockchain is extremely very fast and scalable, transactions are less costly as compared to the Etherium and Bitcoin and I have also seen how it recovered from it's outbreak 1week ago just within 17hours. This is to proof that the Solana blockchain is one of the most important block chain in the world due to its reputation and growth, we can also see how the SOLA token has gain grounds at a very short time frame

It is rank number 7 at the current ranking despite it officially coming into existence just last year. I see the solana block chain competing with the top Blockchains in future because of its rapid growth
