The concept of cryptocurrency was created in 1991. However, the first real implementation was done in 2008 by Nakamoto. The first question arises, what is cryptocurrency. It is a financial setup in which the currency is transferred between the two parties. In the beginning, problems like double fault method arose, although the problem was subsequently solved by concepts like blockchain technology. The whole process is controlled by the cryptographic algorithms. A set of public and private keys is transferred between the two parties. The detail of each transaction is stored in each block and for each customer; a chain of blocks forms the complete list of transactions. All the blocks together form the block chain. These blockchains are nothing but the financial ledger. The power of this new currency transaction system depends on the power of cryptographic algorithm. With the implementation of algorithms such as DES, the confidentiality of every financial transaction (blockchain) has been strengthened. However, the concept has still not been approved by many countries. The data of each block cannot be changed retrospectively or without network consensus. The share of cryptocurrency is currently not that large, but over time it is expected to rise.

Some of the features of cryptocurrency are:
• Decentralized
• Distribute
• Public ledger
The most important aspect of cryptocurrency is the above, but technology requires security for effective use. Problems such as duplicate errors have occurred in the past, but that problem has now been resolved. The biggest advantage of cryptocurrency is its update function without touching the central server. We therefore do not need to make any changes to the server. The transaction can also be done between any two members of the network or three or more.
Several benefits that you gain through the cryptocurrency are as follows:
• Safe
• Fast
• Reliable
• Accurate
However, the technology has evolved even though it is not accepted by all countries. The biggest sensation in cryptocurrency is the bitcoin. This is accepted by many countries. Similarly, you can find many more types of cryptocurrency. Each of them uses a unique type of algorithms. You can learn them all through cryptography. This is a major topic and its application in the form of cryptocurrency is one of the major breakthroughs of the past decade. The use can certainly increase fourfold in the coming years.

Digital currency is also used as part of dubious institutions such as online illegal businesses, for example Silk Street. The first Silk Street was closed in October 2013 and two more forms have been used since then. In the year following the underlying shutdown of Silk Street, the number of unmistakably dull markets expanded from four to twelve, while the rate of medication placements expanded from 18,000 to 32,000.
Darknet markets show challenges regarding legality. Bitcoins and various types of digital money used as part of dull markets are not clearly or legally ordered in all parts of the world. In the US, bitcoins are referred to as “virtual resources”. This kind of dubious arrangement puts weight on law enforcement agencies around the world to adapt to the moving drug exchange of dull markets
