As barter system introduce the transactions process. Afterward, leather money uses for transactions, which later turn to metal, then gold asserts itself in trading. In addition, with the passage of time transaction process introduce paper money.

Finally, technology introduces the digital money for the transaction in all over the world. Which is most flexible and convenient. while, In the general discussion of the technology, blockchain is at the top of the list. Now, the question is, what is blockchain? how does it work? And many more discussion will be available in this article.

What is blockchain?

The blockchain is a technology to verify and record the digital made transactions. It is directly underlying technology to the bitcoin. This technology has the ability to transfer, inform and secure the money. Basically, it is a term which describes the distributed network database technology underwrite once and read the only system. Here, we can observe the one thing,

Bitcoin = blockchain

Ethereum = blockchain

Other crypto-currencies = blockchain

Smart contrast = blockchain

Distributed ledger technology = blockchain

 

Everything about blockchain

 

Blockchain technology has the four major components. Are given below;

  • Privacy: System provides the complete security to its followers regarding their transactions and its recordings.
  • Smart contracts: This system is enabled to add in and being able to execute on individual chain codes.
  • Establish consensus: If you have a strong distributed ledger then participants and a network will agree to the transactions happen. Which need to be a means of establishing consensus between two or more parties.
  • Control: A database which easily shares by different organizations. Whereas, no one authority has full control over it. Which differentiate it from other traditional database platforms. Where multiple people are using this database, there is always one party to write read and connect it to others.

 

Why blockchain seeks the other’s attentions???

People who don’t like traditional transactions system and bored up because of a time-taking process of payments. Accordingly, interested to adopt a new, secure and fast system of transactions. They tend toward the blockchain technology.

Founder and CEO of multichain Dr. Gideon Greenspan say, “People are interested in Bitcoin because of, first of all, it’s technologically interesting. It’s a combination of ideas that’s may have been used before but the way they’re put together and the end result is smart and unique. The second reason is because it enables censorship free digital finance: That is a goal that has never been achieved before. The idea that you can transact digitally with who you want, without there being any central place that can be pressured or switched off is new. The third is the endless speculation in the price, as it goes up and down. It’s an endless story in itself which keeps people interested”. In addition, “People are interested in private and permission blockchain because they offer the possibility of making certain types of IT systems more efficient. This effects IT systems of multiple organizations where companies need to communicate with each other.

Distributed ledger

Basically, it is a recode of what you have. As blockchain is completely different from traditional database technology. in addition, with no central storage and no central administrator of a ledger.

Accordingly, it is an asset and can share across the world. However, this technology id so-called blockchain. people create it and tend to digital cash of the bitcoin. Bitcoin and other cryptocurrencies are accumulating in blocks. And, then by using the cryptographic signature, the blocks are add to the chain.

Benefits of blockchain

  • Secure way of transactions and crystal clear process.
  • Miners authorize the transactions. Transactions become immutable and secure from hacking.
  • blockchain technology minimizes the existence of the third party in transactions.
  • decentralization of the technology.

Whereas, Banks and other organizations are going to invest in this space. Following are some banks and other FIs on the blockchain.

Bitcoin Value Graph- Complete Information About Bitcoin Prices

Want create site? Find Free WordPress Themes and plugins.

Bitcoin’s cost is measured by fiat money, for example, American Dollars, Euro, etc. Bitcoin, therefore, appears similar to any symbol traded on trade markets.

Unlike fiat, however, there is no official Bitcoin cost; just different averages in light of price feeds from worldwide exchanges. Bitcoin Average and CoinDesk are two such names detailing the average cost. It’s typical for Bitcoin to trade at a price marginally different to the normal price.

But inconsistencies aside, what factors determine the price of bitcoins? well, the main factor is supply and demand. The fact that bitcoin is limited in nature leaves the currency mainly at the mercy of supply and demand. When the Bitcoin demand is high, supply drops, and the price goes up and vice versa.

Bitcoin price history is very interesting. In 2009, which was its first year it was just $0.39 per bitcoin. now it is valued at more than $7,000.00 per BTC. Stunning isn’t it.

Here is a Bitcoin value graph giving you an idea of how its price has moved over the years:

Bitcoin Value Gragh

Looking at this Bitcoin value graph, it can be easily determined that Bitcoin value has been on a constant rise over the last couple of years, and the trend is expected to continue in the future as well.

How Bitcoin Works in 5 Minutes (Technical)

Want create site? Find Free WordPress Themes and plugins.

Bitcoin is a decentralized digital currency. There is no physical existence of Bitcoin, just the verification and value it has been given by a global peer-to-peer network. All these transactions are recorded in Blockchains.

The blockchain is very much like a public shared ledger. All the confirmed transactions performed ever using Bitcoins are recorded in this ledger. These blocks are an ultra-secure data, treated like cash. All the transactions are received and sent through wallets which are digitally signed. To ensure security, bitcoin wallets come with a private key or seed. These signatures ensure that the transaction is performed by the current owner of the wallet and provides with the mathematical proof. In reality, there is no transfer of Bitcoins but the change of ownership and quantities of Bitcoins.

How Does a Transaction Work?

If person A needs to transfer Bitcoins to person B, the transaction carries three parts.

  • An Input- record of wallet of person A
  • An Amount- the number of bitcoins person A sends to person B
  • An output- person B’s wallet

How Can You send Bitcoins?

To send the Bitcoins to anybody you require two things.

  • Bitcoin address
  • Private key

A bitcoin address is generated by an individual randomly. It mainly consists of a sequence of numbers and letters.

A private is a secret key with a unique sequence of numbers and letters.

When person A wants to send coins to person B, she signs a message with her private key to authorize the transaction. The transaction will include,

  • Input (source wallet)
  • Number of Bitcoins to sent
  • Output (person B’s address)

Person A then sends the number of Bitcoins to the Bitcoin network from her wallet. Once entered in the network, miners will then verify the transaction included in the blockchain. The miners will then solve the mathematical puzzle and in the end, it will verify that person B is the new owner of the specified number of coins.

Blockchains

Just like account ledgers containing amount and names, blockchains function almost the same. People exchange money by changing this file.

For instance, if person A sells a product to person B for $5, person A’s balance goes up by $5 and person B will have a reduced balance of $5.

There are no third parties involved in the system, like banks or other financial institutions. So, who takes control and responsibility of controlling and maintain this ledger? Every coin holder maintains their own copy of the ledger. All the participants can see each other’s ledger and their balances. In Bitcoin ledgers, these names are exchanged with specific numbers to ensure anonymity.

To keep every ledger synced and harmonized, there is a protocol that needs to be followed. To do a transaction you tell everyone by broadcasting a message with your account number, the receiver’s account number and the amount to be transferred. Every coin holder around in the world will update their ledger.

There are people who help in maintaining the system. You can simply use the system to perform the transaction without maintaining the ledger.

To ensure sender is the real owner of the account, Bitcoin requires a signature to verify it, but a mathematical signature.

System

When an account is created, a private key is generated mathematically linked to that account number. The private key and the text from the transaction are processed through a special cryptographic function to generate a signature. To make sure the signature is done by the wallet owner and to the specific transaction, another function allows the other people to verify the signature. These signatures cannot be copied as they are unique to each transaction.

The main problem with the system is that this cannot verify when a transaction was performed.

For example, if a person falsely has to withdraw 2 cheques out of an account but it has enough money to cover one account. the bank will refuse the second cheque due to an inadequate amount of cash after the with drawl of the first cheque. It is much harder to determine the order in Bitcoin. Due to the scattered individuals all over the world taking part in the transaction, there may be a delay in different orders in different places. Fraudsters could lie about these time lapses.

Two recipients might both think their transaction is first and ship a product allowing the fraudster two spent the money twice.

New transactions go into a pool of pending transactions. These transactions then get into the giant chain that locks in their order. A lottery is then held, enabling participants to choose a transaction of their choice to solve a special problem to link them to the end of the chain. The person to find the solution first wins and gets their transaction next in the chain.

That’s how pretty much all the transactions in the Bitcoin system are performed.
