Benefits of Cryptocurrency

Over the past few years, cryptocurrencies have increased in popularity. In the last year, there more than 1,600! The number of cryptocurrency is increasing every day. This has led to an increase in the demand for developers working on the blockchain (the basis technology behind cryptocurrency like bitcoin). Blockchain developers are highly valued by their pay. According to Indeed, the average amount for a full-stack programer is in excess of $112,000. There is a dedicated website available for cryptocurrency-related jobs.
Whether you’re interested in the field of blockchain developer or you just want to keep up with the latest technology trends the video that provides a comprehensive explanation of the concept of cryptocurrency and the reasons why it’s so important to help you get off to the right foot. This is a recap of what’s discussed in the video.
A An Introduction to Cryptocurrency

In the early days of the caveman, people used barter systems, in which services and goods can be exchanged between two or more people. For instance, someone might exchange seven apples for seven oranges. The barter system was thrown out of popular use because it had some obvious shortcomings:

The requirements of people must be in line. If you’re looking to trade something, someone else has to want it, and you need to be interested in what the other person has to offer.
There is no standard measurement of value. You must determine the number of objects you’re willing exchange for other items, and not all items can be divided. For instance, it is not possible to split a live animal into smaller units.
The goods cannot be transported quickly, unlike our modern currency, which can be stored into a wallet or stored on a mobile phone.

When the barter system wasn’t working very effectively, the currency went through several variations in 110 B.C., an official currency was created; and in A.D. 1250, gold-plated florins were introduced and utilized throughout Europe in the 1600s. From that point until 1900, the paper currency gained widespread acceptance and was eventually used around the globe. This is how the modern currency we have today was created.

Modern currency is described as coins, paper currency as well as credit cards. It also includes electronic wallets such as Apple Pay, Amazon Pay and Paytm. The government and banks are the primary owners of it, which means that there is an centralized regulatory body that regulates how credit card transactions as well as paper currency function.
Traditional Currencies vs. Cryptocurrencies

Imagine a scenario in which you need to repay the person who gave lunch for you, by sending money online to their account. There are a variety of ways in the event that this goes wrong for example:

The institution may have a technical issue that could mean its systems are down or the machines aren’t working properly.
A friend or you may have had your account compromised. This could include a denial of service attack or identity theft.
Your friend or you could have exceeded the limit of transfer for their account.

There is a common point of failure: the banking institution.

The future of cryptocurrency is in the realm of currency. Imagine a transaction similar between two people who use bitcoin. The notification asks the user whether they’re ready to transfer bitcoins. If so, the process occurs by the system that authenticates the user’s identity, confirms whether the user has the required balance for the transaction and then on. After that the transaction will be transferred to the recipient’s account. This all happens in just a few minutes.

The cryptocurrency removes all the difficulties of modern banking: There are no limitations to the funds you can transfer, your account cannot be compromised as well as there is no single point for failure. There are more than 1,600 crypto currencies as of the year 2018, including the most well-known ones like Bitcoin, Litecoin and Ethereum. And a new cryptocurrency crops every day. Based on the rapid expansion they’re seeing right now, there is a good chance that there will be more!

Moving forward, let us discuss what is cryptocurrency.
What is cryptocurrency?

A cryptocurrency is a type of digital or virtual currency that is meant to be a medium of exchange. It’s very similar to the real world currency, but it doesn’t have a physical form, and utilizes cryptography for its work.

Since they operate on their own and are decentralized and decentralized, they are only able to be added to units that meet specific requirements. For example, with Bitcoin it is only after the block is added to the blockchain is the miner rewarded with bitcoins, and this is the only way new bitcoins can be created. Bitcoins are limited to 21 million. After that, there’ll be no more.

Cryptocurrency has many benefits

The transaction cost for cryptocurrency is minimal, in comparison to, for example the cost of transferring money from a digital wallet into the bank account. Transactions can be made at any hour of the day or night. There are no limitations on purchases or withdrawals. You can use cryptocurrency without any restrictions and unlike opening a bank account, which requires documents.

The speed of international crypto transactions is faster than wire transfers as well. Wire transfers can take up to one day for money to be transferred from one location to another. When using cryptocurrencies, transactions are only a matter of minutes or even seconds.

What exactly is Cryptography?

Cryptography employs encryption and decryption to protect communications from third-party hackers with malicious intent. This means that they could take your information or listen in on your conversations. Cryptography utilizes algorithms such as SHA-256 which is the hashing algorithm used by Bitcoin. A public key is a digital ID of the user which is shared with everyone. A private key is a digital signature that is protected by a secret code and is known as a private key.

Bitcoin Transactions Cryptography

In the beginning, you must know the details of the transaction: whom you wish the bitcoins to be delivered to and how many you would like to transfer. Next, the information is processed by an algorithm for hashing. Bitcoin employs the SHA-256 algorithm, as mentioned. The output is sent via a signature algorithm using the user’s personal key. This key lets the user be uniquely identified. To allow other users to verify, the digitally signed output can be then distributed to the internet. This is done by using the sender’s public keys.

Miners are the users who ensure that the transaction is legitimate and verify the transaction. Once the process is finished the transaction, along with the others are placed on the Blockchain, which is a secure place where transactions cannot be changed.

Bitcoin vs. Ethereum

Bitcoin is a decentralized digital currency. It is based on blockchain technology. Bitcoin also uses a peer to peer network to conduct transactions. Ether is a different popular digital currency, and is accepted in the Ethereum network. The Ethereum network makes use of blockchain technology to create an open source platform for creating and deploying applications that are decentralized.

The most well-known and popular cryptocurrency of the moment is Ethereum and Bitcoin. Both rely on blockchain technology. transactions are added to a container known as the block. A chain of blocks is made where data is not modified. In both cases, the currency is mined through a method known as proof of work that involves a mathematical equation that must be resolved before a block is able to be added to the blockchain. Bitcoin and ether can be used worldwide.

You can use Bitcoin to send money. The way it works is similar to the way real-life currency works. Even though Ether is used to fund transactions within the Ethereum network, it is also able to be used in real life. Bitcoin transactions are executed manually. This means that you are required to make the transactions on your own. Transactions can be made manually or automated using ether. They are also programmed which means that transactions only occur after certain conditions are satisfied. As for the time frame, it can take about 10 minutes to complete bitcoin transactions. This is the time it takes to get a block added to the blockchain. When using Ethereum, it takes approximately 20 seconds to complete the transaction.

There’s a limit on the number of bitcoins that can exist: 21 million. This number is supposed to be reached by the year 2140. Ether is expected be around for some time , and it will not surpass 100 million units. Transactions that involve goods or services can be completed with Bitcoin. Ether makes use of blockchain technology to create a ledger that initiates transactions when a certain condition is met. Finally, Bitcoin uses the SHA-256 algorithm, while Ethereum utilizes the ethash algorithm.

Future of Cryptocurrency

When it comes to cryptocurrency the world is divided. On one side are supporters like Bill Gates, Al Gore and Richard Branson, who say that cryptocurrencies are superior to conventional currencies. Some people like Warren Buffett Paul Krugman and Robert Shiller are against it. Krugman, Shiller, both Nobel Prize winners in economics, describe it as an illegal Ponzi scheme used for criminal activities.

There is likely to be a conflict in the near future between privacy and regulation. Because a number of cryptocurrencies have been associated with terrorist attacks, governments would be interested in regulating how cryptocurrency function. However the primary goal of cryptocurrencies is to ensure that users remain in complete anonymity.

The futurists predict that by 2030, cryptocurrencies will constitute 25 percent of all national currencies that means a large part of the world could begin to believe in cryptocurrency as a method of exchange. It will be more accepted by customers and merchants. The volatile nature of cryptocurrency will mean that prices will fluctuate, just as they have been for the past few decades.
