Brief History Of Cryptocurrency


Cryptocurrency can be defined as a digital property purposely made to function as a medium of exchange that makes use of cryptography offer maximum security of all business operations, to handle the way extra units of the currencies are generated and to authenticate properties transference.

Cryptocurrencies fit into group of virtual, alternative and digital currencies that employ the decentralized system of control that is totally different from the centralized system being used by central banking and electronic money systems. This decentralized system of transaction works through a blockchain that harbors the database of the public transaction, functioning as a circulated ledger.


Bitcoin came into existence in the year 2009 and was the first ever decentralized cryptocurrency created. After that, there have been proliferations of other cryptocurrencies. They are always referred to as altcoins as a short form of alternative coin.


How Do Cryptocurrencies Work?

Cryptocurrencies possess a very strong and multiplex codes and mechanical controls that maintain and secures it, although it is possible for ordinary people to grab the elementary concepts to use it.

Cryptocurrencies express their value in units just like the conventional currencies like dollars. For example, you can say, I want to exchange 1.3 bitcoin the same way you would say that you want to exchange $1.3. There are so many factors that determine the value and security of cryptocurrencies.


Key Points In Cryptocurrencies

Public Ledgers:

The main place all the confirmed dealings from when the cryptocurrency was created are stockpiled is the public ledger. All the identities of the owners of cryptocurrency owners are well encrypted, with the system making use of other cryptographic methods to make sure the record keeping is authentic. The ledger makes sure that every digital wallet can compute the amount that can be used from the balance. In addition, all fresh transactions are checked to make sure that the transaction makes use of coins that they owner has. This is referred to as a transaction block chain.



The users of cryptocurrencies get confirmation as the authentic owners of their units through their wallet information, while the genuineness of the transaction is confirmed with the private keys. Crypto wallets help to reduce the risk of losing units that are not in use to theft. There are chances of hacking the wallets of cryptocurrency exchangers as can be seen in the case of Mt. Gox who was hacked of a sum of $450 million in Bitcoin that has been transacted in his server. For security of information, wallets are duplicated and backed up either on external storage or on an internal drive in the cloud.


Block chain

The block chain of a cryptocurrency is the main ledger that keep records and stock all previous transactions, validating the ownership of all the units of cryptocurrencies within a specific time period.

Similar replicates of the block chain are stocked in a node of the software network that cryptocurrencies use, which is the network of decentralized system server, operated by team of individuals who are technologically oriented called miners, that constantly track and authenticate the transactions of cryptocurrencies.

Any transaction carried out on cryptocurrency is not complete until it is included in the block chain, which happens in few minutes from the time the transaction occurred. You can hardly reverse transactions that have taken place in cryptocurrencies unlike the conventional payment methods, like credit cards and PayPal. This is because there is no option for chargeback or refund in the cryptocurrency wallets, although latest cryptocurrencies have tried to incorporate fundamental refund features. It is advisable therefore, to ensure the accuracy and authenticity of every transaction that involves exchange of cryptocurrencies online in the quest for making money online before approving it.

Although during that lag period, between when the transaction was started and when it became finalized, none of the parties involved can make use of the units. This makes block chain to stop the same currencies being used twice or the units being duplicated and forwarded to many recipients.


Private keys

All holders of cryptocurrencies have a unique private key that confirms their identity and permits them to exchange units. The users can generate private keys for themselves, which appears in a format of whole numbers ranging from 1 and 78 numbers long, or utilize an arbitrary number generator to create their own keys. Once the key is generated, they are now eligible to receive and send cryptocurrency. The holder of a cryptocurrency account cannot perform the business of spending or converting their currency without obtaining the private keys.

This may seem to be a security measure to prevent stealing of the cryptocurrency, it has its negative side. Once a private key is lost, it can never be recovered, although a new key can be created and used to accumulate cryptocurrency again.



The miners are those who keep the record for cryptocurrency holders, and invariably, the arbiters that affect the value of the currencies. Miners utilize high-end technical system to ascertain the accuracy, totality and security of block chains of cryptocurrencies.

Miners work occasionally to generate new duplicates of the block chain, including the recent, past unverified transactions that was not added to the last block chain copy, which brings the transaction to a completion. Every addition is referred to as block chain. Every transaction that was carried out since the previous copy of the block chain was generated is the block.

Miners are responsible for creating wealth in the form of new crypto units. Every new copy of a block chain generated has a two-side monetary reward: a set number of newly mined crypto units, and a flexible number of units that already exist, gotten from optional transaction levy that buyers paid. This makes cryptocurrency mining a good passive income business that you can do online to make money, if you have the money to invest in it.
