Cryptocurriencies and Blockchains....(part-03.end)

Cryptocarbon (eg, Bitcoin) is like a network. Each peer has a complete history of all transactions and thus has the balance of each account balance. For example, a Transaction file says, "Simple x gives Bitcoin Alice to the amount" and it is characterized by the characteristic key of Shamasul Huq. This is the basic public key cryptography.After the signing, a transaction spread to the whole network and it was sent from one peer to another. This is the basic P2P technology. Below are the infographics from the idea how blockchain and cryptocarcons work. Clicking on the image will be able to see the bigger.

The transaction is completed very quickly. But after certain time it is confirmed. Much like to confirm by activating an account. This confirmation is very important for cryptococcasins. As long as the transaction is uncertain, it may be postponed and fake.When a transaction is confirmed, it is perfectly set to the laser. It can not be further modified, can not be deleted. That means you can not change the laser information and you can change This process is largely done by blockchain, whicOnly the miners can confirm the transition.
It's basically the miner's work on the cryptocurrenary network. They take the transition, spread it to the network after laser deposits. Whenever the transaction is confirmed by the miner, it becomes part of the continuous blockbuster.h has been discussed earlier.Miners get the tokens (called Fee) for cryptocurrencies (for example: Bitcoin) for this purpose. Since the activities of Minor's activities are the most important part of the cryptocurrence-system, so we will try to know about miners.
The current regulator is the government and central bank of any country. Considering the central bank may be private or private like the United States, it can create a new currency considering the country's economy and many other things. The new banknotes can be printed directly in Bengal. That is, the regulator can do it on their own, in case of loss of profits, they do not sweat their heads, but they often leave them. For example, we have inflation due to printing more money than required in our country.

But cryptocarbones are completely different. Here the new currency or bitcoin comes every 10 minutes to solve a cryptographic puzzle. And this puzzle competition is through miners.
Those who know encryption need to know the SHA256 encryption. Those who are not known, it will be known, if any data is encrypted on SHA256 then there is a hash for that data. For the convenience of understanding hash, "000001beeca3785d515897041af0a7" is something like this.
Now if there is a slight change from this data, then a different hash can be found. That means, if the encryption is done then the hash will always be the same for a specific data, and the same will be the same on everyone's computer.
Now notice, the above hash that I used there is 5 zero at the beginning. It's deliberate. And that's the cryptographic puzzle that I said earlier. There are numerous transactions in the world of Bitcoin blockquanes every moment. After adding a new block in Blockchain, approximately 10 minutes of pending transaction data, Bitcoin, all the miners on the system get into the computer. So, the meaning of the minarets is that we ourselves and we are sitting with the computer to solve puzzles.

We have a target of mine or miners, the data that we have at the moment, the hash of the previous block and the other with Random Number (here it is called Nonce = Number Used Once), find the hash of a pattern like this at the beginning of the top 5. . Why this 5th Zero? It is said, the difference level, that is, how many zeros will sit at the beginning, it's actually hard to solve the puzzle.

In this way thousands of miners from all over the world have been competing to find the desired hash on their computers. This process does not really win with any special algorithm or intelligence. After absolutely the Bangla system, one should use nonce or expression to check if the pattern hash has been found.

In this competition, the miner can first find out that this hash wins. Finding a hash is to create a new block for a new blockchain. Not nice? The rest of the miner who did not win, their job is to verify that the results of the winning miner are correct. Thus, possibly 51.7% of the verb has been verified, then the new block is added to the Blockchain as a tested or correct block.

There are many types of cryptococcerning. If Bitcoin is more used in cryptococcensation. There are also many kinds of cryptocurrencies
