Cryptocurrencies have become increasingly popular over the past several years - as of 2018, there were more than 1,600 of them! And the number is constantly growing. With that has come to an increase in demand for developers of the blockchain (the underlying technology of cryptocurrencies such as bitcoin). The salaries blockchain developers earn show how much they are valued: According to Indeed, the average salary of a full-stack developer is more than $112,000. There’s even a dedicated website for cryptocurrency jobs.
Whether you’re interested in a career as a blockchain developer or you just want to keep up with the latest trends in tech, Simplilearn’s Cryptocurrency Explained video explains what cryptocurrency is and why it’s important will get you off to a good start. Here we’ll recap what’s covered in the video.
A Brief History of Cryptocurrency
In the caveman era, people used the barter system, in which goods and services are exchanged among two or more people. For instance, someone might exchange seven apples for seven oranges. The barter system fell out of popular use because it had some glaring flaws:
People’s requirements have to coincide—if you have something to trade, someone else has to want it, and you have to want what the other person is offering.
There’s no common measure of value—you have to decide how many of your items you are willing to trade for other items, and not all items can be divided. For example, you cannot divide a live animal into smaller units.
The goods cannot be transported easily, unlike our modern currency, which fits in a wallet or is stored on a mobile phone.
After people realized the barter system didn’t work very well, the currency went through a few iterations: In 110 B.C., an official currency was minted; in A.D. 1250, gold-plated florins were introduced and used across Europe; and from 1600 to 1900, the paper currency gained widespread popularity and ended up being used around the world. This is how modern currency as we know it came into existence.
Modern currency includes paper currency, coins, credit cards, and digital wallets—for example, Apple Pay, Amazon Pay, Paytm, PayPal, and so on. All of it is controlled by banks and governments, meaning that there is a centralized regulatory authority that limits how paper currency and credit cards work.

Traditional Currencies vs. Cryptocurrencies
Imagine a scenario in which you want to repay a friend who bought you lunch, by sending money online to his or her account. There are several ways in which this could go wrong, including:
The financial institution could have a technical issue, such as its systems are down or the machines aren’t working properly.
Your or your friend’s account could have been hacked—for example, there could be a denial-of-service attack or identity theft.
The transfer limits for your or your friend’s account could have been exceeded.
There is a central point of failure: the bank.
This is why the future of currency lies with cryptocurrency. Now imagine a similar transaction between two people using the bitcoin app. A notification appears asking whether the person is sure he or she is ready to transfer bitcoins. If yes, processing takes place: The system authenticates the user’s identity, checks whether the user has the required balance to make that transaction, and so on. After that’s done, the payment is transferred and the money lands in the receiver’s account. All of this happens in a matter of minutes.
Cryptocurrency, then, removes all the problems of modern banking: There are no limits to the funds you can transfer, your accounts cannot be hacked, and there is no central point of failure. As mentioned above, as of 2018 there are more than 1,600 cryptocurrencies available; some popular ones are Bitcoin, Litecoin, Ethereum, and Zcash. And a new cryptocurrency crops up every single day. Considering how much growth they’re experiencing at the moment, there’s a good chance that there are plenty more to come!

In the private consumer world, Blockchain technology can be employed by two parties who wish to conduct a private transaction. However, these kinds of transactions have details that need to be hammered out before both parties can proceed:ethereum habrahabr Lastly, randomness. While most people recognize that there is intelligent design in bitcoin’s foundation, what is often missed is the randomness through which it evolved and that what it became (money) was largely a function of that randomness. Lightning was caught in a bottle; it was a result of thousands of people making thousands of independent decisions very early on. But the process also continues to this day. From cryptographers and developers contributing time and energy, to companies and investors building infrastructure, and to users just wanting to find a better way to store value. If the reset button was hit going all the way back to 2008 when the bitcoin white paper was released, and the same initial code was released, placing the same people in the same rooms, bitcoin would very likely not be what it is today. It may be 'better' or 'worse,' but ultimately it was and continues to be a product of randomness. It is not the product of consciously directed thought, and it expands beyond the resources of individual minds because of that fact. For those that perceive flaws in bitcoin and have (or had) ideas of how to make a better bitcoin, the intelligence of bitcoin’s design is often observed and acknowledged. Design can be copied and individual features can be changed out, but randomness cannot be replicated.mining ethereum bitcoin token casper ethereum gek monero exchange bitcoin bitcoin box js bitcoin приват24 bitcoin 16 bitcoin bitcoin расшифровка sgminer monero bitcoin валюта bitcoin nedir p2p bitcoin майнить ethereum криптовалюту bitcoin bitcoin мошенники new cryptocurrency black bitcoin ethereum parity bitcoin auto icon bitcoin ферма ethereum bitcoin миксер программа ethereum bitcoin capital btc ethereum cryptocurrency news polkadot stingray bitcoin настройка пулы bitcoin 10000 bitcoin теханализ bitcoin кости bitcoin bitcoin инвестирование bitcoin авито pull bitcoin ethereum blockchain monero difficulty
