What is a Nonce in Block Chain?
Cryptocurrency like Bitcoin uses the Block chain as a decentralized, distributed, public digital ledger that records all the transactions of the Bitcoin. Block Chain has a unique feature of storing the value of previous block as a hash value in the current block, which makes it impossible to alter any block without changing all the subsequent blocks.The miners create a block and verify it and will be rewarded for using their CPU power to do so. The block which gets more than 50% consensus will be added to the block chain. During the verification of Block, the miners will complete ...
Read MoreWhat is the Difference Between a Block chain and a Database?
The difference between a Block chain and a traditional database begins with architecture, creation, access, and permissions. They differ in each and every aspect except that they both are huge repositories of data which is stored and accessed in an organised form, digitally.DatabaseThis runs on a client-server network, where there is a central repository of data that will be accessed by those nodes who have permission to access the data. The data of the database is maintained by administrators, and mostly nodes will have access to retrieve the data as per their requirement.Database, which is an electronic collection of data ...
Read MoreWhat is the difference between Proof of Work and Proof of Stake?
Bitcoin is the first and foremost cryptocurrency ever created. It is the digital currency which is created, used and maintained electronically. The transactions of a digital coin are written in Blocks and maintained in the Block Chain, which is a distributed, transparent and digital ledger.During the process of mining the Bitcoins, the miners (computer nodes with high power graphic processors) of the network solve the hash algorithms, difficult math problems and mine a block to earn bitcoins as reward. This is how Bitcoins come into market.What is Proof of WorkThe original idea of Proof of Work belong to Cynthia Dwork ...
Read MoreHow do you earn bitcoins?
Bitcoin is the latest buzz in the world of digital currency at the moment and those who see its significance from a permissive outlook, they go for it because they know it that through this magical currency they can make money faster and become rich. Well, I am sorry to burst that bubble, but to be honest; Bitcoin is like any other currency out there. Like there is no easy way to make money, similarly, there is no other or magical way to gain cryptocurrency or Bitcoins too.However, cryptocurrency may open up a new method of earning, but the basic ...
Read MoreWhat is Bitcoin's Lightning Network?
Ever since Bitcoin came into existence in 2008, scalability has been one of the important drawbacks. Well, let us understand what is the scalability. Bitcoin is capable of processing around 7 transactions per second, when compared to 24, 000 transactions per second by Visa. Given the magnitude of increase in transactions every day, the system is getting congested for the last few years. One more issue with this is, more time a transaction takes, it uses the more resources and thereby increasing the transaction fees.The Bitcoin’s Lightning Network came up as a solution for this problem. This is being tested ...
Read MoreWhat is consensus protocol in Block Chain?
Consensus protocol is one of the most important aspects that makes the Block chain network a fool proof system. It is the revolutionary protocol that makes the Block chain network an irrefutable system where the majority of devices (nodes) connected to the network agree on each and every transaction. This prevents exploitation of the system as more than 51% consensus is required to create a new block. It is the core of the Block Chain which makes it certain that the information stored on the Block Chain is accurate and honest.The very core of the Nakamoto’s Block chain consensus protocol ...
Read MoreWhat are Blocks in a Block Chain?
Bitcoins or any other cryptocurrency for that matter, trade at different values. These values are based on supply and demand and most importantly on speculation. The Block chain is the chain of block that stores the information of the transactions of a Bitcoin. Satoshi Nakamoto created the first block in 2009, which is called the Genesis Block.Block Chain is a distributed ledger which stores the data in Hash values. Every digital currency has its own block chain that keeps a record of all transactions ever done using that currency.Peer to Peer Network or P2P Network allows everyone to have a ...
