If you are here to explore the easiest approaches to learn blockchain, then you must have a basic impression of what the technology is.

Blockchain technology is rightly the next big technology following the internet with many global names such as Amazon, IBM, Facebook, and Microsoft spearheading blockchain adoption.The large scale demand for adoption of blockchain technology delivers a critical boost for the demands to find best ways to learn blockchain.

Enterprises are looking for blockchain professionals in different roles, such as cryptocurrency traders, mining technicians, blockchain developers, blockchain architects, full-stack developers, and research analysts.On average, blockchain professionals can earn almost $150,000 to $175,000 as annual salary, thereby increasing the need for learning about blockchain.

Aspiring learners could choose online courses for the appropriate structuring and streamline of topics related to blockchain technology.

Online video tutorials are the best option to learn almost anything, whether it is about cooking a new recipe or making home improvements.

As a result, learners could use video tutorials to learn about blockchain comprehensively.Gaming AppsBlockchain gaming apps are the trusted methods for taking away the boredom in learning blockchain technology.

Ethereum BlockchainBlockchain is open-source, public, and blockchain-based distributed platform and operating system featuring a smart contract functionality, Ethereum allows distributed applications to be built and executed without any downtime, fraud, control, or interference from a third-party entity.Ethereum is a Turing-complete programming language going for walks on a Blockchain that helps developers publish Develop Ethereum blockchain applications.One of the principle tasks around Ethereum is Microsoft’s partnership with ConsenSys which gives Ethereum Blockchain as a Service (EBaaS) on Microsoft Azure to business organization clients and builders with a unmarried click on cloud-based blockchain developer environment.Ethereum Blockchain Size depends solely on implementation.

How does Ethereum work?Ethereum operates with a protocol similar to Bitcoin and its blockchain design.

However, it is programmed so that the applications are compatible, as long as they are not money systems.

The similarity between both block chains is presented in the transaction history, since each one is responsible for storing them.

Ethereum, in turn, requires that each node within the network download the current state, all the code and where each of the smart contracts that are within it is stored, along with the balance of each user.

Mining is a process by which groups of nodes or miners solve mathematical puzzles to obtain the new currencies that have come into circulation.

Definition of Dapps?dapps operate autonomously without a central control entity with all the changes decided by the proposals and the consensus of their users.Why developers can interest on Dapps:without a central authority, they are architecturally superior to centralized applications.Typical definitions include the following attributes:The code is open source and managed autonomously.Logs and data are stored by blockchain, which provides reliable interaction and avoids any single point of failure.Use cryptographic tokens to reward users who provide computing power.Tokens generated through a cryptographic algorithm.

The advantages of Dappsfault tolerance.

If an application becomes too popular or is the victim of a denial of service attack, the application developer cannot do anything except cry.On the other hand, Dapps have their resources and functionality distributed among the peers in the blockchain.What makes it extremely expensive to attack with traditional denial of service attacks, since they do not depend on a single server.The other important advantages that dapps have over their centralized counterparts are that they reformulate the dynamics.Platforms such as Facebook, Twitter and Instagram depend on the content that their users produce and consume.With regular applications, the centralized entity is the maximum beneficiary of the effort contributed by its users.With Dapps, its decentralized governance models ensure that power is redistributed so that application users and their software creators can benefit in a more egalitarian manner.dApps in ActionThe Bitcoin and Ethereum are considered dApps Ethereum and currently is the main platform to create dApps.

With Solidity, Ethereum allows developers to form smart contracts using the tools of the Truffle Framework, and they can also test their smart contracts and deploy them on the blockchain.Examples of decentralized apps based on Ethereum that have reached millions of dollars in market value are Golem (computing power), Augur (forecasting market) and Melonport (digital asset management).

These projects aim to reconfigure the economy using blockchain technology and bring us closer to a decentralized world.

Dapps, the future for the delivery of information without manipulationAlthough the technological advantages of Dapps can be very clear, when it comes to really unlocking the potential of dapps, since being a decentralized part the manipulation of the data is quite difficult.A clear example that we can give is the role social networks play in political events, a clear example was in Egypt some years ago.Another example is the scandals that were announced in elections in some countries, where social networks have been used to favor certain candidates.Given this, Dapps can completely change the landscape, but one element is still missing: real-time data.Most developers, of course, are completely familiar with the advantages of real-time information.But the integration of quality real-time data sources for decentralized applications brings serious challenges.Currently, Dapps that handle only crypto transactions within the scope of the blockchain do not need to think about these problems.

How the Blockchain will affect investment process and real Estate?The blockchain is breaking as one of the most disruptive technologies and promising for the future of transactions and therefore also the online investment .

Investing in housing , in other processes or acquiring real estate through this technology will be a reality thanks to this 'blockchain'.

We explain how:Cryptocurrencies, the money used in blockchainThere are several types of virtual currencies, but the best known is Bitcoin.

Soon its popularity increased along with its value.Can I buy a house with bitcoins?The answer is yes .

On the other hand, since it is a fluctuating value, if at the time of the transaction the price of bitcoin rises and profits are obtained, the real estate agent must pay it.And what will the blockchain guarantee?To summarize in a very simple way the blockchain , it is like a large account book where each and every one of the operations appear digitally registered.

Each information management and update will be reproduced equally in each of the multiple nodes (computers or hard drives) that store the information, which guarantees unprecedented fairness, veracity and transparency in all data.

Blockchain in AgricultureDid you know that the total number of deaths in the world is due to hunger?

Of course, the food shortage increases along with the increase in the population.

One of the reasons is that food is only spoiled because of the inefficient food supply chain.The food supply chain is inefficient with current technology, and most of the work is still done manually.

Consumers are very concerned about this because they affect health.

For this reason, the scammers make a lot of money by exploiting innocent consumers.These issues must be resolved with the highest priority because there are no compromises when it comes to health.The solution:Food waste can be eliminated and avoided by making the food supply chain efficient.

The farmer benefits by getting the fair price for his products by eliminating middlemen, hunger can be satisfied and food fraud can be eliminated.How is it possible?Blockchain offers transparency; it shows what is happening in the blocks so that everyone in the block can see where the product comes from; and whether it's organic by using smart IoT devices in the farm that recognize the use of pesticides and chemical fertilizers.

Centralized cryptocurrency Exchange: This is online platform and the most common way to trade cryptocurrencies.This includes buying / selling cryptocurrency with fiat currency (fiat currency / crypto pairing) and buying / selling cryptocurrency with other cryptocurrencies (crypto / crypto pairing).

For example, in a bank, a customer transfers their money to the bank.

In many cases, this is safer than people who find ways to manage themselves.

Banks can also provide various services, such as loans, because banks have largeInvested funds and established a trust relationship with customers.To develop a Centralized cryptocurrency exchanges are no exception.

In short, decentralized cryptocurrency exchange (DEX) cuts off middlemen by creating a highly intelligent “trustless environment”.

The transaction is done through smart contracts and atomic swaps, so the currency will never go through the escrow service-it is just peer-to and so on.DEX is still in its infancy and is not very popular yet, but decentralized trading in 2018 may make great progress.
