what is cryptocurrency..?

 Distributed ledger technology (DLT) is one of the key technologies responsible for bringing the openness of the web back without compromising its security. The commercial and legal transactions can now be handled completely on the web as DLTs provide a more secure and accountable environment for exchanging digital assets in the forms of currencies, popularly known as cryptocurrency.

A distributed ledger is a distributed record of transactions, maintained by consensus among a network of peer to peer nodes. Consensus can be described professionally as an acceptable resolution, one that can be supported. It is basically a mechanism that is used to achieve the required agreement on a single data between the distributed system. It is useful in recordkeeping.

This means that certain rules should be followed before adding a new block to the chain. It further states that for anyone to earn the right to add information or block in the ledger one must solve the cryptographic problem which requires computational power to solve. The most widely recognized form of DLT is the blockchain structure, which provides the basis for cryptocurrencies and a variety of other applications.

Limited Concurrent Transactions

  The Bitcoin block system requires connection and confirmation from the peer-to-peer network to be verified. Because each block contains a limited record of transactions and an upper limit to the number of new transactions that can be written, there’s a limit to how many people can buy and sell with the system at any given time. As more and more vendors and individuals use Bitcoin to do business, the number of transactions per second increases, and the peer-to-peer network is becoming congested, with some operations without transaction fees taking hours to clear. Whereas conventional payment systems like credit cards can simply expand their connections and processing power to speed up processing, the isolated peer-to-peer nature of bitcoin doesn’t allow it to scale with the global financial system. Black Market Appeal A central principle to the design of the Bitcoin system is that there is no single transactional processing authority. As a result, no single user can be locked out o

Bitcoin Mining Has Diminishing Returns

  A few years ago when the Bitcoin system was new, individual users “mined” for new Bitcoins at a rapid pace. Bitcoin mining software used local processors, and even extra processors like a computer’s graphics card, to calculate hashes for the next block in the blockchain. While the number of people using and “mining” Bitcoin was low, each user doing the mining would randomly confirm the next block at a higher pace, generating new Bitcoins for his or her account quickly. But this boom in generation couldn’t last. The Bitcoin system is designed to make each new block more difficult to find than the last one, reducing the number of randomized Bitcoins that are generated and distributed. That means that as time goes on, each individual mining for them has to work harder and harder (in a figurative sense—it’s the computer that’s working harder and using more electricity, and thus, costing more conventional money). As the number of individual Bitcoins grows, the amount of Bitcoins rewarde
