A currency beyond the limitations ,Bitcoin.



An unknown Japanese person or group (named  Satoshi Nakamoto)  designed bitcoin and made first blockchain database. They also solved the double spending for digital currency and released as open source software (Bitcoin). Bitcoin is an innovative way of payment across the world. Bitcoin network is peer to peer (point to point) and transactions are made between users directly. This can also be said as the electronic money or digital currency. Through which the system can work without a single or central bank. In a much-secured way, nodes verify transactions by using cryptography (secret coding) and it is recorded in a blockchain (distributed ledger).


The value of bitcoin currency is dynamic, it doesn’t remain similar or static. Bitcoin symbols are as follow :

Usage of Bitcoin

According to the research that was produced by Cambridge University, there were between 2.9 million and 5.8 million unique users using a cryptocurrency wallet, in 2017, most of the peoples use bitcoin. The number of Bitcoin users has been increased significantly since 2013 when there were 300,000 to 1.3 million users. Also visit Valforex.



The blockchain is a public ledger (distributed database) that helps to record bitcoin transactions. Having run the bitcoin software, a network of communicating nodes perform the maintenance of the blockchain. Transactions can be delayed and added to network nodes.  each network node stores its own copy of the blockchain.  Almost 6 times per hour, a new group of accepted transactions, a block, is created, added to the blockchain, and fast published to all nodes.  This permits bitcoin software to determine when a specific bitcoin amount has been spent, that is important in order to prevent double-spending in an environment without central overlooking.


Bitcoin mining is the process to add transaction records to Bitcoin’s public ledger of blockchain or past transaction. The ledger of past transaction is a chain of blocks. By using computer processing power, record keeping service is made possible. A complete and unalterable blockchain is kept by miner grouping newly broadcast transactions into the blocks. Then which is broadcast to the network and approved by recipient nodes. Every block contains an SHA-256 cryptographic hash of the previous block, thus it is linked to the previous block and given the blockchain its name.


Bitcoin miners make the Bitcoin network secure by approving transactions. Mining is an important and integral part of Bitcoin that ensures fairness while keeping the Bitcoin network stable, safe and secure.

Pooled mining

Computing power is “pooled” to decrease variety in miner income or bundled together. In a pool, All participants miners get paid every time when a participating server solves a block. Almost Individual mining rigs have to wait for a long time to confirm a block of transactions and receive payment. This payment depends upon the number of work that an individual miner contributed to help to find that block.


A good miner finds the new block that is rewarded with new bitcoins and transaction fees. As of 9 July 2016, the reward collected to 12.5 newly created bitcoins per block added to the blockchain. For claiming the reward, a special transaction called a coinbase is included with the processed payments. All bitcoins in existence have been made in such coinbase transactions. The bitcoin protocol describes that the reward for adding a block will be halved every 210,000 blocks (approximate in every four years). Finally, the reward will be reduced to zero, and the limit of 21 million bitcoins will be reached 2140; then the record keeping will be rewarded by transaction fees solely.


A wallet is supposed to store or holds bitcoins because of its nature and it collects all necessary information regarding transacting bitcoin and wallet also allow one to access and spend bitcoins. bitcoins are inseparable from the blockchain transaction ledger. A better way to describe a wallet is something that “stores the digital assets” for your bitcoin holdings.


The unknown inventor (Satoshi Nakamoto) designed bitcoin to use as a currency. According to the economists, Bitcoin is difficult to earn, it is easy to verify, limited to supply   It is referred terms such as electronic currency, cryptocurrency, digital cash.This matter is still a dispute that bitcoin is currency or not. the bitcoin network is considered to be decentralized and it doesn’t have centralization policy.  Economists define money as a store of value, a medium of exchange, and a unit of account and admit that bitcoin may be gone to meet all these standards.

Criminal activity

  The attention of Media, Legislative bodies, Law enforcement has been attracted by the criminal use of bitcoin. In the USA, to stop such criminal activities FBI has prepared an intelligent assessment.
