Greetings, Steemians!

I am waseem from Pakistan
Welcome to in Steemit Crypto Academy Contest | S1W3 blockchain post 😊

Question's

• 1 Tell us about your favorite concept or term related to blockchain, try to be explanatory and make sure to give your opinion. (For example: Decentralized, Genesis Block, Hard Fork, Proof of Stake.)

• 2 Why do you think it is important in the blockchain?

• 3 Do you think that the existence of the blockchain would be possible without this concept? Is there an alternative or similar term?

• 4 Do you think it is possible to improve this term in some way? Explain us how

Short History Of Blockchain

David Cham is an American computer scientist who came up with the concept of a blockchain-like protocol in 1982 as a cryptographer.
This was the time when computers were developing and working on the computer window
Advancing David Cham's concept in 1991, Stuart Haber and W. Scott Stornetta worked day and night to improve the cryptographic chain.
In the meantime, work began on creating a digital currency in the computer world
Satoshi Nakamoto appeared as a developer or developers
And this man issued a white paper in the year 2008
From which the blocks were shown and also the hash method for time stamp was shown on these blocks. Today this person is known by every person working in corrupt currency.

Blockchain Through the Concepts

This is one of the most secure technology that cannot be hacked. It is distributed laser technology
This technology works on the block system and keeps the data of each block transaction safe. This data cannot be changed nor can this secure data be changed.
Online Ledger Technology DLT is a distributed technology that saves the associated data of transactions across different locations simultaneously.
To avoid any mistakes, every computer in the blockchain network has a copy of the ledger, which is updated online, making it impossible to make mistakes.
Blockchain technology is a database different from any normal database in terms of how it is stored and operated. Are connected to each other. If one block is replaced, it becomes different from the other, which is why it becomes impossible to hack it. The seller and the seller can connect

How Blockchain Technology Works

There are two types of entries in online transaction and blockchain technology using this technology. There is a header inside the block and the data about the transaction is stored which uses a specific time frame.
The block has a time stamp used in the blocks to create a hash which is a character number string when the first block is created by storing its data. Calculates the hash

The legal status of any new block is verified before it is added to the chain

Source
Ensures that all copies of the dedicated ledger blockchain contain the same data in the same format
After the first block, when the second block is created, this block is referenced
Once the data is saved, it cannot be changed
If the hashes of any block are changed, the laser will cause an error because not all computers are the same and the network will issue alerts to all other computers.
And unless the hashes bug is fixed, the system will not work, and no new block can be added to it, unless the bug is fixed.
And that's what makes this technology secure

Why do you think it is important in the blockchain?

Proof-of-work algorithm is one of the types that works in blockchain technology and without it blockchain would not be complete.
People use different methods to manipulate the blockchain. Different people can come up with fake transactions through manipulation.

It is used to authenticate transactions and to secure blockchain networks.
Without this algorithm the blockchain system can fall prey to various hackers and manipulators and this is why simple users fall prey to fraudulent transactions and lose their money.
Two people using p2p can cheat on each other
Two people who do business can deceive each other
The buyer may give a fake entry which will force the seller to release his asset as he will be sure that the buyer will send him money which is an asset that the person sitting on the other side can cheat and agree to avoid. An algorithm is used in which all the computers work together to verify the entry which reduces the chances of fraud

Some of the key components of blockchain technology are POS - Hard Fork - Decentralization - Genesis.
All these things have to work together. Without these things this blockchain technology fails and it cannot become decentralized.
Its blockchain technology makes transactions faster and stronger
This technology does not require any additional examples to act as mediators for validation
From which I can quickly verify the transaction
And that's what this technology is all ab

Do you think that the existence of the blockchain would be possible without this concept? Is there an alternative or similar term?

To my knowledge, blockchain has all these functions like decentralized, POS, blocks. These are the basic principles of blockchain technology.
Blockchain technology is one of the most transparent systems in which translation is made transparent
This system can only work well if the data written on any blockchain cannot be changed, erased, or distributed. With rows and columns attached and most importantly it can be trusted and it is completely secure.

I don't think blockchain technology can be successful without all these things
There is no substitute for this blockchain technology and that is what makes this technology secure

Do you think it is possible to improve this term in some way. Explain us how ?

If you can understand, more work needs to be done on this technology and this system can be further improved.
POW security and decentralized to be reliable and secure
No answer
This system completely verifies the transaction and then allows further processing.
The largest stakeholders provide verification power on a daily basis
There is no need for complicated calculations
When we talk about energy efficiency in this system, it goes beyond the evidence
This network is capable of verifying the transactions of the crypto users
Most people who work in cryptocurrencies provide liquidity with their doctor
And prefer to earn commissions
The POS consensus system can be further improved and more profitable.

Conclusion

This blockchain technology has a powerful system that can store very large amounts of data in its database very fast. It cannot be manipulated with this system. It can be bought and sold after verification by various computers. Transacts between engravings
This is the most reliable and secure platform
This is the most
