Hi all, Thank you very much @crypto-academy for this opportunity.

In the crypto market, we have more than 500+ blockchain networks. Some are public, some are private. Some work both together.

From this my 1st favourite Blockchain network is Ethereum. No doubt about it.

I think all crypto users are most familiar with this Network.

Ethereum is open source Decentralized Blockchain Netwok. After Bitcoin, we see Ethereum in the second rank from its market value.

_{Basic Details}

At present, it trading around a Price of $3008.10 with a Market Cap of $362,613,547,533 with the Second Rank.

Its Total Supply is around 120,518,678, present calculating supply is also the same. So there are no new ETH coins came into the market.

ETH Is a native coin in Ethereum Blockchain Network. For doing any activities in the Ethereum network we need ETH, For paying gas fees and some other activities needs.

About Ethereum Network

At first, Around 2013, Vitalik Buterin along with other co-founders introduce Ethereum 2013 and conduct public sales in 2014.

On July 30, 2015, Ethereum officially launched its Blockchain Network with a new concept called Smart Contracts.

Ethereum is very easy to access, for accessing applications just needs a wallet. No need for any keys, emails or other things to access Ethereum Network.

We can access this blockchain from any place throughout the world. There are no restrictions. So any developer can develop their project using Ethereum Network from any place as per their needs.

Ethereum also allows peer-to-peer transactions. Here you can also add your conditions for order executions. This feature helps a lot to deal with different companies securely.

It's a complete decentralized block gain network so no government involvement here, so no one stops to send or receive money here. Also, get 100% security.

Ethereum Blockchain we also called as World's Programmable Blockchain.
Because here you can programme our needed conditions for executing our orders, like this feature we don't have in Bitcoin Network.

Ethereum also builds on seeing Bitcoin Innovation but with different other features. On solving Bitcoin network issues like scalability, transaction fee and time.

Use cases of Ethereum Blockchain

Ethereum is a digital currency like Bitcoin.

• Ethereum is a Digital Currency. So we can use this currency as a payment needs, also we can transfer this currency to any other person or family members as a gift as per our wish.

• Smart Contracts: On using this feature orders can execute without anyone's permission, orders execute automatically if conditions have been met.

• Decentralized Apps: on the Ethereum network, a lot of Dapps build using its features. Here users can play games, invest, send or receive money, and also do social activities. And more activities related applications build on Ethereum Network.

• Non - Fungible Tokens: Everyone knows about this NFT trend in the market. Ethereum plays a key role in developing this market. Here any artist can sell their art, for this he receives his money in his wallet. All those transactions are done through smart contracts.

• Decentralized Finance: We know Ethereum is an open-source Decentralized blockchain network. So for operating financial related big payments, this network is a good choice. Because here we can transfer money to others very easily.

All those features attract me a lot and become one of my favourite blockchain networks.

It has a lot of features but also some disadvantages.

For doing transactions on the Ethereum network we need to pay a transaction fee in form of ETH. This few is called. gas fee.

In the Ethereum network based on the rush on the network, those fees start increasing. Sometimes for doing a $5 transaction we need to pay $50 as a gas fee.

That's why small investors hesitate to use Ethereum Blockchain.

At the same time, there is no guarantee to execute our orders, so here we lose our gas fee, sometimes taking a huge time to execute orders.

Like those issues we having in Ethereum Network. For solving those Ethereum Development team start moving their network from Proof - of- Work to Proof - of- Stake.

This migration is named Ethereum 2.0.

_{Updates Of Ethereum 2.0}

But it's not an easy task, very hard to migrate, so it takes time to resolve present issues. But the team developing very hard to resolve all those present issues.

For this Ethereum merge use case and how it works, we can check this video.

The network earliest shortcomings and how the network's team took care of the problem.

Ethereum Blockchain is powerful block chain. But at early stage its also face shortcomings issues regarding scalability.

At early stage of Ethereum Blockchain we having DAO contract related issues. Those are very common in any block chain at earlier stage but in Ethereum Network it become more worse.

Because in Ethereum Blockchain it store each variable used inside that contact, due to this it need more memory to store all those data.

That's why at first only big companies only possible to use this Network.If any blickchain run on big companies only is called as Centralized Network not Decentralized.

Then after developers start resolving this issue, not only this at first in Ethereum Network we can do only 5 transactions per second. After doing lot of developments from Ethereum team now they trying to solving scalability and Transaction speed related issues slowly.

Changes that I wish In Ethereum Network.

Due to the high demand for Ethereum, it becomes very expensive to access. So I wish some changes to Ethereum Blockchain, from this it become better than others.

• At present In Ethereum Network executing around 30 transactions per second. But compare with present demand it's not suitable. So the team must focus on it.

source

• Fir executing orders in the Ethereum network we need to pay $25 to $500 as a gas fee here based on our needs. It's very high, so small investors are not possible to handle it. So if it fee came under $1 then a lot of people start accessing this blockchain.

• Sometimes our transaction becomes failed but a gas fee would be deducted from our wallet. It's not fair coming my view, due to this failed transaction we lost a lot of hard-earned money. So the team must be focused on it too.

• At present Ethereum network uses high computing power to protect its network, due to this users pay high fees for executing their orders. So if they use another alternative method like proof- of- stake we reduce this cost. So transaction fee becomes more reliable to users.

Like those changes, if the Ethereum network is full fill, then we can see great changes in this network.

I strongly believe after arriving Ethereum2.0,We can see major changes in this network.

Projects that build on Ethereum Network

By using the Ethereum Blockchain network we can build Dapps, NFTs, games, Payment related applications and many more as per our needs.

Today I giving details about OpenSea, an application built on Ethereum Blockchain.

source

World's first and largest peer-to-peer marketplace for Non-Fungible Tokens. Here we can Buy/Sell NFTs as per our needs. Artists can sell their art to anyone in the open market. That money artist directly gets in their linked wallet.

Here we can sell our art, Gaming items, collectables and many more. Each NFT has its own Identity, so not possible to duplicate our collection. So here we get 100% original NFTs.

At first opensea marketplace start with ***
CryptoKitties*** on Ethereum Network in 2017 by software engineers Alex Atallah and Devin Finzer.

source

Due to the high gas fee on Ethereum Network, now Opensea offers gas less free services using a polygon network. So now a lot of traders daily access the opensea platform for their needs.

Even I am also collecting my favourite NFTs after supporting the polygon network. Because due to high gas fees on the Ethereum network, I do t use it before, but now I using for my needs regularly.

Opensea supports any Decentralized wallet like Trustwallet, Metamask and many more. Just connecting our wallet to opensea platform is enough for Buying/Selling NFTs.

No need for any other details to access this platform. Its work is very smooth and easy to access. In mobile also we can access the Opensea Platform very easily through Decentralized Wallets.

Thanks For Reading Basic Details Regarding Ethereum Blockchain.
