On a cold November morning in 2012, agents of the U.S. FDA (Food and Drug Administration) paid a surprise visit to ‘Castle Cheese Inc’ – a cheese factory based out in rural Pennsylvania. The company that was till then known for selling 100 percent real parmesan to some of the most renowned grocery chains was found to use substitutes and fillers such as wood pulp in their product. What followed next was an untold story of fraud and deceit about a company that had been known for manufacturing and distributing safe, healthy and honest product for almost a century.
Till now most of the people across different verticals know what blockchain is and how it is one of the most innovative technologies that has the potential to disrupt various industries. Blockchains are immutable, and forge-proof making them the best platform for data related transactions. Blockchain also happens to be a platform that prevents a diverse range of frauds including identity theft, financial forgery, data thefts and more. While collecting all the necessary information about Blockchain and its functions, most of us misunderstand the mechanism behind such a tamper-proof nature of this incredible technology. The secret of Blockchain security and tamper proof nature is ‘Cryptography’.
Cryptocurrencies, just like the fiat currency, are needed to be stored and secured. And just like the physical wallets, the cryptocurrencies also are kept in the wallets and generally, referred as Crypto wallets. In Crypto wallets, it is not the real coins that are stored inside, rather digital codes or two types of keys i.e. Private and Public key. Public key is visible to everyone and is used by others to send money. On the contrary, private key is used only by the owner of the wallet to perform send transactions. Losing the Private Key can result in loss of the currencies, since you lose whole control over your wallet and this is the reason it is recommended that at least two different techniques should be used for saving and storing of the private keys.
The world is finally moving to the next level of revolution in IT & Internet. The Blockchain is tout to be ‘the internet 3.0.’ It is based on the distributed ledger technology, though the real potential of this technology was realized only when the Blockchain came into existence. And when, still many people are in the process of understanding use cases of the Blockchain Technology beyond Bitcoin, a new technology is making news, hyped as the ‘future of distributed ledger,’ the Hashgraph.
Smart Contract, also called as self-executing contract, blockchain contract or digital contract, is a set of instructions that automatically performs the obligations under the agreement, which parties have committed to. By being immutable and cryptographically secure, Smart Contract gives us the security of Blockchain Technology, that is, it provides distributed trustworthy calculations.
