What is Cryptocurrency

 Imagine you're having a conversation together with your friends. Now at some point during this conversation, someone's getting to mention cryptocurrencies. Now cryptocurrencies are some things that everybody wants to speak about, but nobody really knows how they work. So today I'm getting to fix that I'm Raul from simply learn. And this is often cryptocurrency explained since man a world currency has been a really important a part of our lives. within the caveman era, they used the barter system. Now the barter system involves goods and services being exchanged among one another . for instance , say you've got five apples and your friend has five oranges, you would like a number of us oranges. Now until and unless your friend features a requirement for the apples that you simply own, he'll not be able to make an exchange for it. there is no common measure useful . Now since there's no common measure in terms of which value of a commodity are often expressed, there's a drag once you need to decide what percentage apples you're able to trade for one orange or a mango.

Not all goods are often divided or subdivided. for instance , you'll divide a live animal into different smaller units, the products can't be transported easily. Now unlike our model, currency fits in your wallet or your mobile , the products that you simply own can't be crazy you everywhere you go. After realizing that the barter system didn't work alright , currency went through a couple of iterations. In 110 BC, and officially currency was minted in 1002 50. And from 1600 80 to 1900. Ad paper money gained widespread popularity and was used across the planet . this is often how modern currency as we all know it came into existence. Modern currency included paper, currency and coins, credit cards and digital wallets. for instance , you've got Apple Pay, Amazon, pay, pay, tm, pay, pal, and so on. Now this suggests that there was a centralized regulatory agency that limited how paper money and credit cards worked. Now imagine the scenario of doing a web transaction here you're thanking a lover for paying for your lunch, and you're saying that you're sending the cash to their account. Now this transaction takes place successfully.

 But there are several ways where this might have gone wrong. There could are a technical issue at the bank, for instance , the systems could are down the machines were in working properly, and so on. meaning there is a central point of failure, which is that the bank, the users accounts could have gotten hacked, for instance , there could are a DDoS attack or fraud , and so on, or the transfer limits for that account were exceeded. this is often why the longer term of currency lies with cryptocurrency. Imagine the transaction between two people within the future. one among them has the Bitcoin app, and there is a notification asking whether they're sure they're able to transfer five bitcoins If yes, processing takes place. Here. We're authenticating the users identity, checking whether or not they have the specified balance to form that transaction and other things. Now after that's done, the payment is transferred and therefore the payment is received. All of this happens during a matter of minutes. And it's as simple as that. This successively removes all the issues of recent banking, there is no limits to the funds, you'll transfer your accounts can't be hacked and there's no central point of failure. Now, as of 2018, there's quite 1600 cryptocurrencies available. Now there are some popular ones like Bitcoin Litecoin, 

Ethereum and Zed cash and a replacement cryptocurrency crops up every single day. Now considering what proportion growth they're having, at the instant , there is a good chance there's plenty more to return within the upcoming years. So what exactly is cryptocurrency? A cryptocurrency may be a digital or virtual currency that's meant to be a medium of exchange. Now, cryptocurrency is sort of almost like world currency just that it doesn't have any physical embodiment. It also uses cryptography to figure the way it does. Now a number of the features of cryptocurrency or there is a limit to what percentage units can exist with Bitcoin this limit exists at 21 million. After this, no more bitcoins are going to be produced, you'll easily verify the transfer of funds. Now the hashing algorithms that Bitcoin uses makes it very easy for users to work out whether a transaction is valid or not. They operate independent of a bank or a central authority they add a decentralized manner. Now, new units are often added only after certain conditions are met. for instance , for Bitcoin only after block has been added to the blockchain, will the miner be rewarded with bitcoins and are often "> this is often the sole way new bitcoins can be generated. So what makes cryptocurrencies so special? Firstly, there's little to no transaction costs. Now, if you employ the digital wallet, you recognize that if you're transferring money from your wallet to your checking account , you lose some amount of cash , you've got 24 seven access to money, you cannot just walk up to your bank at 3am within the morning, and say that you simply want to withdraw some money. there is no limits on purchases and withdrawals.

Now this refers to 3rd parties who want to steal your data or want to pay attention to your conversation. Cryptography uses computational algorithms like Aes 256, which is that the hashing algorithm that Bitcoin uses a public key, which is sort of a digital identity of the user, which he shares with everyone and a personal key which may be a digital signature of the user, which he keeps hidden. Now let's mention a traditional Bitcoin transaction. First you've got the transaction details, this details who you would like to send it to and the way much bitcoins you would like to send them. Then it's skilled a hashing algorithm for Bitcoin we use the SGA 256 algorithm, the output that you simply obtain is skilled a signature algorithm with a user's private key. Now this is often often wont to uniquely identify the user this output is then distributed across the network for people to verify this is done by using the sender's public key. The people that verify the transaction to see whether it's valid or not, are referred to as miners. Now, after this is often done, the transaction and a number of other others are added to the blockchain where it can't be changed. Again, if the concepts of hashing seem a touch difficult to you, i might suggest you click on the highest right corner and watch the blockchain explained video in order that you'll understand better now the sj 256 algorithm, like I told you earlier looks something like this. You're seeing how complicated it's . I'm sure it's safe to mention that the encryption is extremely difficult to hack. Today we'll be that specialize in two major cryptocurrencies Bitcoin and ether. A Bitcoin may be a digital currency that's decentralized and works on the blockchain technology. It uses a peer to see network to perform transactions. Let's mention ether. ether may be a currency that's accepted within the Ethereum network. Now, the Ethereum network uses blockchain technology to make an open source platform for building and deploying decentralized applications. 

Now, let's mention the similarities between Bitcoin and ether. They're the most important and most precious cryptocurrencies within the market immediately . Both of them use blockchain technology which is nothing but a technology that involves transactions being added to a container called block and creating a sequence of blocks during which data can't be altered. currency is mined employing a method called proof of labor , which may be a sort of mathematical puzzle that must be solved before a block are often added to the blockchain. Finally, these are widely used across the planet . Now let's mention the differences with Bitcoin. it's wont to send money to someone this is often very almost like how real world currency works with ether it's used as a currency within the Ethereum network. Although it are often used for real world transactions also . Bitcoin transactions are manual, which suggests you've got to personally perform these transactions with ether you've got the choice to form these transactions manual or automatic or programmable, which suggests that these transactions will happen when a particular condition has been met. For Bitcoin, it takes 10 minutes to perform a transaction, which is that the amount of your time it takes for a block to be added to the blockchain. With ether it takes about 20 seconds to try to to a transaction. Now blockchain is employed like money for world transactions and ether is employed to power the aetherium network and power real world transactions also . ether is employed as fuel within the Ethereum network to power both of those things. 

Now there is a limit to what percentage bitcoins can exist which is 21 million. We alleged to hit this number by the year 2140. ether is predicted to be around for a short time , but to not exceed 100 million units. A Bitcoin is employed for transactions involving goods and services and ether uses blockchain technology to make a ledger to trigger a transaction when a particular condition is met. For Bitcoin we use an algorithm called esitate 256. For hashing and with aetherium. Now, what is the way forward for cryptocurrencies? the entire world is clearly divided when it involves cryptocurrencies. On one side, you've got supporters like Gates , Al Gore, and Richard Branson, who say that cryptocurrencies are better than regular currencies. On the opposite side, we've people completely against it. People like Warren Buffet, Paul Krugman and Richard Schiller, who are both Nobel prize winners within the field of economics. They call it a Ponzi scheme and means for criminal activities within the future. There's getting to be a conflict between regulation and anonymity. Since several cryptocurrencies are linked with terrorist attacks, governments would want to manage how cryptocurrencies work. On the opposite hand, the most emphasis of cryptocurrencies is to make sure that their users are kept anonymous. By the year 2030 cryptocurrencies would occupy 25% of national currencies, which suggests a big chunk of the planet will start believing in cryptocurrency as a mode of transaction,
