bitcoin crypto why so popular digital currency new trend

What is bitcoin and how to get it?

According to wiki Bitcoin is a worldwide cryptocurrency and digital payment system called the first decentralized digital currency, since the system works without a central repository or single administrator. It was invented by an unknown programmer, or a group of programmers, under the name Satoshi Nakamoto and released as open-source software in 2009.The system is peer-to-peer, and transactions take place between users directly, without an intermediary.

These transactions are verified by network nodes and recorded in a public distributed ledger called a blockchain.

Established in 2009 after the financial crash, bitcoin is a digital currency that has no central bank or regulatory authority backing it up. The coins don’t exist in a tangible form but are made by computers and stored in a digital wallet or on the cloud. They can then be exchanged and used in transactions.

There is a finite number of bitcoin that can be supplied – 21m – and there are currently 15m in circulation. Its price has fluctuated wildly since it was launched. Seven years ago, two pizzas were bought for 10,000 bitcoin. At its peak at the beginning of September this year each bitcoin was worth almost $5,000. As it can be used as an anonymous way to carry out cross-border money transfers, it has been linked to drug dealing and money laundering.

There are bitcoin ATMs that allow the cryptocurrency to be exchanged for cash, and an increasing number of businesses accept it. Lady Mone, co-founder of underwear brand Ultimo, launched a property development in Dubai with prices in bitcoin, while a London property developer is to allow its tenants to pay their deposits using it.

What is BlockChain

The blockchain is a public ledger that records bitcoin transactions. A novel solution accomplishes this without any trusted central authority: the maintenance of the blockchain is performed by a network of communicating nodes running bitcoin software.

Transactions of the form payer X sends Y bitcoins to payee Z are broadcast to this network using readily available software applications.Network nodes can validate transactions, add them to their copy of the ledger, and then broadcast these ledger additions to other nodes.

The blockchain is a distributed database – to achieve independent verification of the chain of ownership of any and every bitcoin amount, each network node stores its own copy of the blockchain. Approximately six times per hour, a new group of accepted transactions, a block, is created, added to the blockchain, and quickly published to all nodes. This allows bitcoin software to determine when a particular bitcoin amount has been spent, which is necessary in order to prevent double-spending in an environment without central oversight.

Whereas a conventional ledger records the transfers of actual bills or promissory notes that exist apart from it, the blockchain is the only place that bitcoins can be said to exist in the form of unspent outputs of transactions.
