The principal decentralized computerized digital money can be followed back to "Bit Gold", which was taken a shot at by Nick Szabo in the vicinity of 1998 and 2005. Bit gold is viewed as the principal forerunner to bitcoin. In 2008, Satoshi Nakamoto (an unknown individual as well as gathering) discharged a paper itemizing what might move toward becoming Bitcoin.
Bitcoin turned into the main decentralized advanced coin when it was made in 2008. It at that point opened up to the world in 2009. Starting at 2015, Bitcoin is the most normally known cryptographic money. Given the prevalence of Bitcoin and additionally its history, the expression "altcoin" is here and there used to depict elective digital forms of money to bitcoin.
As of January 2015, there were more than 500 distinct sorts of cryptographic forms of money – or altcoins – for exchange online markets. In any case, just 10 of them had advertise capitalizations over $10 million. Starting at 2017 the aggregate market capitalization of all digital forms of money achieved an unequaled high passing $60 billion!
As such, cryptographic money isn't only a craze, it is likely a developing business sector that (regardless of its upsides and downsides) is likely here for the whole deal.

What is cryptocurrency?
At the time of writing, the concept of decentralized cryptocurrency is still in its infancy, having been conceived in January 2009 by a pseudonymous researcher going by the name Satoshi Nakamoto. The open source project known as Bitcoin was created on the proof-of-concept principle that transactions can be securely processed on a decentralized peer to peer network without the need for a central clearinghouse.
Centralized management has always been a part of other digital forms of payment, such as credit cards or wire transfers. The nature of the open source cryptocurrency protocol does not allow for traditional disadvantages such as chargebacks or double spending due to the use of signed encryption keys, effectively removing fraud risk from the merchant.
The prominence and popularity of cryptocurrency technology has quickly spread through the general public as means to store and transfer wealth, as well as engage in secure e-commerce. As with any new technology that generates rapid global interest,
cryptocurrencies have been targeted by malicious actors seeking exploitation of the experimental nature of the protocol.
These attacks have come in the form of data breaches, targeted attacks against end users, and state sponsored regulation.
Cryptocurrencies are physical precomputed files utilizing a public key / private key pairs generated around a specific encryption algorithm. The key assigns ownership of each key pair, or ‘coin,’ to the person who is in possession of the private key. These key pairs are are stored in a file named ‘wallet.dat,’ which resides in a default hidden directory on the owners hard drive. The private keys are sent to users using dynamic wallet addresses generated by the users engaged in transactions.
The destination payment address is the public key of the cryptocurrency keypair. There is a finite amount of each cryptocoin available on the network, and value of each unit is assigned based on supply and demand, as well as the fluctuating difficulty levels required for mining each coin.
The wallet.dat file is the most important file of the cryptocurrency software architecture, as that is where the physical cryptographic private key file is stored. Much like cash, if a user loses their wallet.dat file, or has it stolen, the cryptocurrency is lost.
The decentralized nature of open source protocol ensures that the control of the network remains in the hands of the users. Transactions are dependent on participants in the network, and the user responsible for the security of their own finances and data, without the need for reliance on third parties such as banking institutions.
Bitcoin operates as a p2p file sharing protocol, and therefore the concept is similar to .torrent technology. The p2p network relies on user participation for successful trusted data exchange. Each transaction is confirmed through key verification on multiple nodes in the network before reaching its destination. This crowdsourced key verification process guarantees the integrity of the data transfer.
The most popular cryptocurrency at the time of writing is Bitcoin, with alternatives such as Litecoin rapidly gaining market traction. The source code for these programs, as well as the code for other cryptocurrencies, are available on all major open source code repositories.
