Smart Contract- Definition, How Does it Work  Smart contracts (also called distributed apps) are very popular nowadays.  But what are they and what problems do they solve?  The term “smart contract” was first used by Nick Szabo in 1997 , long before Bitcoin was  created.  He is a computer scientist, law scholar and cryptographer so I’ll spare you his exact words. But in simple terms: he wanted to use a distributed ledger to store contracts.  Now, smart contracts are just like contracts in the real world.  The only difference is that they are completely digital.   In fact, a smart contract is actually a tiny computer program that is stored inside a blockchain.  Let’s take a look at an example to understand how smart contracts work.  You probably are familiar with Kickstarter, the large fundraising platform.  Product teams can go to Kickstarter, create a project, set a funding goal and start collecting money  from others who be...

 How does Blockchain Works? Blockchains are incredibly popular nowadays. But what is a blockchain? How do they work, what problems do they solve and how can they be used? Like the name indicates, a blockchain is a chain of blocks that contains information. This technique was originally described in 1991 by a group of researchers and was originally intended to timestamp digital documents so that it’s not possible to backdate them to tamper with them. Almost like a notary.  However it went by mostly unused until it was adapted by Satoshi Nakamoto in 2009 to create the digital cryptocurrency Bitcoin.  A blockchain is a distributed ledger that is completely open to anyone.  They have an interesting property:  once some data has been recorded inside a blockchain,it becomes very difficult to change it. So how does that work? Well, let’s take a closer look at a block. Each block contains some data, the hash of the block and the hash of the previous block. The data t...

  Complete Solidity Tutorial | Ethereum Solidity | Solidity Blockchain Development | Smart Contract   What is Solidity ? Solidity is a contract-oriented, high-level programming language for implementing smart contracts. Solidity is highly influenced by C++, Python and JavaScript and has been designed to target the Ethereum Virtual Machine (EVM). What is Ethereum? Ethereum is a decentralized ie. blockchain platform that runs smart contracts i.e. applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. The Ethereum Virtual Machine (EVM) The Ethereum Virtual Machine, also known as EVM, is the runtime environment for smart contracts in Ethereum. The Ethereum Virtual Machine focuses on providing security and executing untrusted code by computers all over the world. The EVM specialised in preventing Denial-of-service attacks and ensures that programs do not have access to each other's state, ensuring co...

  Blockchain Developer Salary in India 2021 On an Average, blockchain developer salary in India lies between INR 5,00,000-30,00,000 per annum  or 5 lakhs-30 lakhs. What is Blockchain technology? Blockchain  technology is a technology which has been invented by the person or a group of a person called  Satoshi Nakamoto. We have discussed the technology in the previous blog on our website. Here we will discuss the  Blockchain Applications   and terms used during the course. In a nutshell,  Blockchain  is a technology that allows direct transaction of data and value without having any central authority between users on a public platform where everyone registered user(node) has access to each and every block of transaction. It allows peer to peer transaction in a  decentralized,  trusted and secure environment. Blockchain  is a technology that permits transactions(it can be a currency, media, doc files, audio files etc) to be gathered...
