3r33548. 3r3-31. The profession of a software developer is extensive and dynamic, changes occur constantly and it is very important to track trends. The new trend of 2017-2018 can be called blockchain (CU). Countless ICOs, an unprecedented increase in cryptocurrency capitalization have attracted a lot of attention here. So there was a great demand in the labor market, and individual developers /software companies began to actively explore the subject area and offer their services. Now it is possible to draw certain conclusions on the profession and on the market, which I would like to talk about.
 3r33548.
 3r33548. If you are also interested, then welcome under the cat, tell you my vision of the situation.
 3r33548.
 3r33548. If everything is simplified as much as possible, then the blockchain developer is the same software developer, who only understood another technology or learned another syntax of a conditionally new programming language. But such short articles are not interesting to write, so we will try to classify the subject area, talk a little about salaries, be sure to talk about the stack and see the short answers of existing CU developers.
 3r33548.
 3r33548. 3r314. 3r3333391.
 3r33548.
 3r33548. 3r33333. What is the blockchain?
 3r33548.
So first, let's talk about what a blockchain is. We mean that everyone already has an understanding, so I will not go deep, but I’ll give two definitions that I like the most. One is simple, the second is difficult.
 3r33548.
 3r33548. 3r33357. The first 3r33358.
 3r33548. Blockchain is an immutable decentralized database.
 3r33548.
 3r33548. 3r33357. The second [/i]
 3r33548. A blockchain is a “cryptographically secure transactional singleton with shared-state machine.” W2w2w20.
 3r33548.
 3r33548. 3r3105.
Explanation of phrases under the cat [/b] 3r3108. “Cryptographically secured by the complex” means that you are obscenely hard to break. Think of a firewall of sorts.
(e.g. create fake transactions, erase transactions, etc.)  3r33548. Transactional singleton machine has been established. In other words, there is a single global truth that everyone believes in.
 3r33548. “With shared state”
 3r33548. 3r3544. 3r3544.
 3r33548.
 3r33548. The definition is taken from here - 3r360. medium.com/@preethikasireddy/how-does-ethereum-work-anyway-22d1df506369
 3r33548.
 3r33548. 3r3147. A simple classification of developers working in the blockchain 3r3148.
 3r33548. Let's try to classify.
 3r33548. It is still too early to classify the industry by technology stack, so it is best to introduce division in relation to the technology itself:
 3r33548.  3r33548.
 3r33548. 3r3147. Mediated ratio 3r3148.
 3r33548. Mediated means that the developer did not have to dive into the technology itself, and for it is used rather as a subject area. For example, someone works with the automotive industry, and someone automates recruiting. This item can include the creation of landing pages for cryptocurrency projects, the use of ready-made APIs from cryptocurrency gateways. This category is not very interesting to us.
 3r33548.
 3r33548. The direct relation to the blockchain can, in turn, be divided into the use of technology results and the creation and development of technology. For example, someone uses elastic search, and someone writes /develops it. Same story here. Blockchain is not rocket science, but just another technology that is fairly easy to use if you don’t, of course, want to develop your network.
 3r33548. 3r3147. Direct relationship (technology results) 3r3148.
 3r33548. In this category, for example, you can include the writing of smart contracts in the language of Solidity. A smart contract is such a thing that is an algorithm like “if this then that” and that can communicate with the outside world with the help of special oracles (http://www.oraclize.it/). For example, on a smart contract you can write a forvadny contract on the price of Bitcoin in a month, and this transaction will be more reliable than any exchange, because full decentralization and genuineness of the data will be incorporated. More can be read here .
 3r33548.
 3r33548. By the way, there are a lot of little-known specialized programming languages ​​for smart contracts. The most complete list is here - https://github.com/s-tikhomirov/smart-contract-languages ​​
 3r33548.
 3r33548. 3r3105.
Just in case, that such a forward [/b] 3r3108. Forward is one of their derivatives in the financial market. A forward contract means that we are already negotiating a price and concluding a deal to buy /sell Bitcoin, but it will be fulfilled only in a month and the winner will be the one who is closer to the market price.
 3r33548.
 3r33548. Details and good about derivatives are written here in this article - 3r3113. geektimes.ru/post/60141
 3r33548. 3r3544. 3r3544.
 3r33548.
 3r33548. The most popular smart contract is to issue a token for ICO. But it has become so popular that there are already designers (https://wizard.oracles.org/), and you can do everything without programming.
 3r33548.
 3r33548. This item also includes such work as creating a personal investor account for ICO. Here the developer needs to understand how the nodes of the ether, Bitcoin are arranged, select tools and frameworks.
 3r33548.
 3r33548. This also includes writing various wallets to cryptocurrencies, creating a stock exchange for trading cryptocurrencies (it seems that every second wants to open a new one :-)), or even simply integrate with exchanges to create their new products.
 3r33548.
 3r33548. 3r3147. Contribution to technology development 3r3148.
 3r33548. Here is more difficult. You can divide into those who write the code itself and those who are engaged in the design. Including theoretical. For example, you need to think through a consensus, and here game theory will help you. Or think over the economy, and here it would be nice to have an economic /financial education.
 3r33548.
 3r33548. The developers of the blockchain node often use C ++, Go. Sometimes Rust and even less Haskell. Kernel developers usually have a mathematical education, it is also important for them to know cryptography.
 3r33548.
 3r33548. 3r3147. What are the difficulties and nuances of 3r3148.
 3r33548. Paradoxically, but front-end programmers are more easily included in blockchain development. The reason is very simple - they are used to having an abstract data layer. Back-end developers and especially database developers more difficult. They are used to the need to protect the database, monitor consistency, integrity. We must understand how to store information. But the blockchain is not so. Here to you:
 3r33548. 3r33177.  3r33548. 3r3191. Openness; 3r33532.  3r33548. 3r3191. Pledged immunity; 3r33532.  3r33548. 3r3191. Security. 3r33532.  3r33548. 3r? 3534.
 3r33548. And everything has been developed and invented before us. Just use it.
 3r33548. But Solidity is a good developer to learn in 3-4 days. It is very simple. But we must understand that it is important to know the best practices, to be aware of the latest vulnerabilities, to be able to conduct an audit.
 3r33548.
 3r33548. It is difficult to go to the blockchain for those who do not like the new and conservative. Often projects require interesting solutions for which standard methods are not enough.
 3r33548. Let's summarize what you can do. Let's just try to enumerate what a HC developer can do:
 3r33548. 3r33177.  3r33548. 3r3191. Writes smart contracts; 3r33532.  3r33548. 3r3191. It is engaged in the development of blockchain nodes; 3r33532.  3r33548. 3r3191. Develops a concept, is engaged in the theoretical part; 3r33532.  3r33548. 3r3191. Projects a consensus (narrow specialization for specific tasks); 3r33532.  3r33548. 3r3191. Develops various dAPP products. 3r33532.  3r33548. 3r? 3534.
 3r33548.
 3r33548. 3r33333. How to study
 3r33548.
In fact, this is a topic for a separate article, for short, there are already paid and free courses on the Internet.
 3r33548.
 3r33548. How can you participate in practice after you learn.
 3r33548. Bitcoin came about thanks to encryption (more about the history here - 3r3209. [url]Https://www.ozon.ru/context/detail/id/135325988/[/url] ), Which means that the main technology behind Bitcoin (blockchain), very good community. Which, in turn, indicates a large number of open-source, simple and complex. For example, the DeCenter project has an excellent Telegram bot ( [url]Https://github.com/DeCenterOrg/moneebot[/url] ). He also ether wallet. The repository has not been updated for a long time. Can help in the development. For example, it is very necessary to introduce a backup and a wallet restoration in 12 words (BIP-3? BIP-3? BIP-44 standards).
 3r33548.
 3r33548. You can also commit to the core bitcoin, but you need to try if you want your pull request to accept.
 3r33548.
 3r33548. Also below are the answers from blockchain developers I know. I hope their comments will help you understand this new industry better.
 3r33548.
 3r33548. 3r33333. Short responses from blockchain developers.
 3r33548. 3r3333317. Konstantin, freelance developer [/b]
 3r33548. 3r33357. How did you get into blockchain? 3r33358.
 3r33548. It happened by chance, even then I was freelancing, and the current customer proposed a project related to the blockchain. I had to understand from scratch, at first it was difficult. It was 2015.
 3r33548.
 3r33548. 3r33357. What exactly did you have to do in the CU? 3r33358.
 3r33548. Did support for multi-subscription addresses in bitcoinJ. Client for bitcoin in java, which is used in most android devices. For an interesting project, COLU did the integration of their protocol and their COLU SDK into an opensource wallet at copay. Poker still did on Ethereum.
 3r33548.
 3r33548. 3r33357. Do you like it? 3r33358.
 3r33548. Like if the project is worthwhile. And so there are big restrictions and a lot of nonsense around the blockchain right now.
 3r33548.
 3r33548. 3r33357. Do you think blockchain developers have higher salaries? 3r33358.
 3r33548. According to my unscientific observations, yes, more. But honestly, I think that there are very few senior developers now, you can count it on your fingers.
 3r33548.
 3r33548. 3r33357. What advice can you give to those who would like to start? 3r33358.
 3r33548. If a person wants, then so will begin. Solidity, for example, is a very simple thing) Mastering Bitcoin can be read.
 3r33548.
 3r33548. 3r3333317. Igor Gulamov, VP Engineering in Bankex [/b]
 3r33548. 3r33357. How did you get into blockchain? What exactly did you have to do in the CU?
 3r33548. 3r33358. Began to actively follow in 201? from 2017 began to work, wrote a few smart contracts. Now full-time in the blockchain, but not quite as a developer, more as a manager.
 3r33548.
 3r33548. 3r33357. Do you like it? 3r33358.
 3r33548. Yes. Interesting, because the blockchain gives new economic tools, anonymity. This is a technology that brings a lot of good things to life.
 3r33548.
 3r33548. 3r33357. Do you think blockchain developers have higher salaries? 3r33358.
 3r33548. Now, during the HYIP, exactly higher. Before HYIP, salaries were like programmers in some esoteric language like Haskell.
 3r33548.
 3r33548. 3r33357. What advice can you give to those who would like to start? 3r33358.
 3r33548. Participate in open-source projects, in the same ethereum. For example, there is a draft store of numbers. There is a large article on github how to program in Solidity. You can start with it - 3r3305. https://github.com/ethereum/wiki/wiki/%5BRussian%5D-%D0%A0%D1%83%D0%BA%D0%BE%D0%B2%D0%BE%D0B4%D1% 81% D1% 82% D0% B2% D0% BE-% D0% BF% D0% BE-Solidity

 3r33548. https://www.linkedin.com/in/sergey-zenkov-1b0713b2
 3r33548. 3r33357. How did you get into blockchain? 3r33358.
 3r33548. For many years engaged in web development. He was interested in the blockchain for a long time, but without specific applications. Once my friends needed help in this area and I agreed to take part in the blockchain project. Now most of the work is already related to dapp applications.
 3r33548.
 3r33548. 3r33357. What exactly did you have to do in the CU? 3r33358.
 3r33548. Basically, I write smart contracts and spend code-review of someone else's code. He also participated in projects to create a custom blockchain. Periodically it is necessary to conduct R & D research for various projects related to warheads.
 3r33548.
 3r33548. 3r33357. Do you like it? 3r33358.
 3r33548. Yes, the industry is new. Thoughts and approaches need others, and it is always interesting. I love to learn new technologies and promising areas.
 3r33548.
 3r33548. 3r33357. Do you think blockchain developers have higher salaries? 3r33358.
 3r33548. It depends on what exactly the blockchain developer does. In general, I think, yes, higher for the current moment. Further it will be already visible on how the industry will develop.
 3r33548.
 3r33548. 3r33357. What advice can you give to those who would like to start? 3r33358.
 3r33548. The main thing is to read the documentation and learn how to obtain the necessary information for work. To work with smart contracts, you need to read all the documentation on solidity, truffle, OpenZeppelin, Infura and the ones you need to work in truffle: chai (bibswelling for asset) and mocha (test framework).
 3r33548. It is crucial to test the code in testnet (ROPSTEN, KOVAN, RINKEBY)
 3r33548. I recommend reading more foreign code, analyzing various business cases of blockchain integration into business processes, using current development patterns and following the code-style of the selected stack. Follow the changes in the industry and the emergence of new tools for developers.
 3r33548. After studying Ethereum and EVM, dive into other blockchains.
 3r33548.
 3r33548. 3r33333. Conclusion
 3r33548. As we see, the profession of the blockchain developer is still in the process of formation. Much more in the industry will need to go through, refine and standardize. But now there is an understanding that demand, and therefore payment in the labor market is definitely higher. By the current moment there is already an understanding of how to enter the profession, where to study.
 3r33548.
 3r33548. Even if you don’t believe in the blockchain at all, and consider Bitcoin to be the biggest bubble, you still need to look closer at the technology, at least from a technical point of view. 3r3544. 3r33548. 3r33548. 3r33548. 3r33383. ! function (e) {function t (t, n) {if (!
