Cryptocurrencies have entered the mainstream and conquered the hearts of many. The technology that underpins them is blockchain, which made it to the top 10 web development trends 2018.This year, you’ll see a high demand and astonishing opportunities for blockchain developers. So, why don’t you start digging into it today? In this post, we bring you a collection of the best blockchain tutorials and guides 2018 so that you could pick the right blockchain tutorial according to your level and ground knowledge. They’ll help you learn how does blockchain work and tap into mastering this technology.
Before we look into the best blockchain tutorials, let’s first get the blockchain technology explained in general terms. Read on and you’ll see what this technology actually is and what value it brings to its users.
Blockchain is a network of records (a.k.a. blocks), which find storage on different PCs across the globe, link to each other and are secured with cryptography. There are millions of computers that store the records of the blockchain database. The blocks reconcile every 10 minutes, providing for autonomy and incorruptibility of the chain. What’s more, the nodes distribute the data of the blockchain in the way that many computers store a single transaction. That’s why no single person can modify the data.
The blockchain has a linear structure. Each block connects to the previous one by the means of a hash pointer. So, if you follow these connections, you’ll eventually end up uncovering the genesis block, which is the first block of the blockchain. Modern blockchains are vast and contain billions of transactions. Some of them get a new block every 3 to 5 seconds. That’s why in 2017, the size of a single developed blockchain was more than 100Gb. However, thanks to decentralization, the data are distributed in the way that all the transactions are publicly accessible and interconnected.
This being said, the employment of blockchain technology brings a number of advantages to people using it. We enumerate the major ones of them below:
尽管如此,区块链技术的应用还是给使用它的人带来了许多好处。我们列举其中的主要问题如下:
First of all, there’s no power or authority governing the blockchain. That’s why there’s no fee you pay for verifying and auditing transactions. What’s more, blockchain transactions are not only cheaper but also quicker.
Secondly, there’s hardly a more secure value exchange technology than blockchain. Each chain node stores just a part of the database. The blockchain replicates this part of the database a number of times across the network of nodes. As a result, there’s no hierarchy, and no central points, vulnerable to cyber-attacks. What’s more, even a single blockchain transaction can’t be modified retrospectively. The blockchain tracks such a violation immediately, as this violation leads to changes in all the subsequent chain blocks.
Next, the blockchain is public and open. Basically, any party or person can join the blockchain and access the needed transactions. So, being equally accessible to all people all over the globe, the blockchain ensures that no group of people gets more power than others in the blockchain.
Given these points, the possible applications of blockchain technology are not limited to cryptocurrency trade. For example, the blockchain technology powers smart contracts, i.e. the contracts that are automatically authorized and undisputed. Smart contracts already find their application in land registration and music industry. Moreover, blockchains effectively simplify medical record management, identity management, online voting, and tracking digital use of copyright materials. Even the giant payment systems, such as VISA, Mastercard, SWIFT, and UnionPay, are already devising the schema of future incorporation of blockchain technology on the global scale.
This being said, mastering blockchain today is a sound investment into the future for a web developer. Fortunately, there’s a number of blockchain tutorials that you can access on the net free of charge or for a moderate price. Let’s review the best blockchain tutorials and guides 2018, so that you know the ways to master how does blockchain work and how to work with this technology.
