If you wish to make your career in network, the Certifications is considered to be the best certification, to jump-start your career. But gaining this certification isn’t considered to be that much easy. You have to go through lots and lots of study process unless you have the help of the Juniper JN0-662 Dumps offered at the ExamClubs.

How to become aBlockchain Developer? Being a revolutionary technology, it opens the ways for newfields of development and with that, more creative and tech enthusiasticbrains. So to become a part of this technology, how to weave your beautifulmind, this article might be a help.

Who is a blockchain developer?

Developer responsible for creating the framework ofblockchain system and optimising blockchain protocols by developing certaincontracts and web apps is commonly called BlockchainDeveloper.

It’s the technology that develops enticement when one getsto know it and why one would not be interested in such an advanced andprogressive field. But before writing a poem, one has to have an associationwith the words to convey the feelings.

So first, let’s clear our insights over the basics ofblockchain.


It is a type of distributed ledger formaintaining a permanent and tamper-proof record of transactional data.


Blockchain is supposed to be a network that is not restrained to oneparticular authority.


It is the ability for a blockchain ledger toremain unalterable and indelible history of communication i.e. once data hasbeen written to a blockchain, it is unalterable.


Blockchain developers who use their mathematical models, andcomputational power to mine for blocks.


Ethereumis a decentralized platform, applications that run exactly as programmedwithout any possibility of downtime, censorship, and fraud or third-partyinterference. This enables developers to create markets, ledgers of debts orcontracts, move funds and many other things that have not been invented yet,all without a middleman or counterparty risk. This application is built usingprogramming languages, just like regular software. Ethereum has its ownlanguage called Solidity


What is cryptoeconomics? Ethereum developer Vlad Zamfir says that cryptoeconomics is:

“A formal discipline that studies protocols that govern the production, distribution, and consumption of goods and services in a decentralized digital economy. Cryptoeconomics is a practical science that focuses on the design and characterization of these protocols.”

Cryptoeconomicscomes from two words: Cryptography and Economics. The decentralized peer topeer system was a failure before. The torrent sites have used it for ages toshare files. But in that process, anybody can share the file with decentralisednetwork. If the file is being downloaded, it is supposed that the person sharesthe files with the network for others to download. And that’s where the problemrose, the people are not interested in keep sharing the file which tookunnecessary space in their computer.

Soin 2008, Satoshi Nakamoto, a group of people released a paper which laid thefoundation for Bitcoin and now, people actually had an economic incentive to “follow the rules”.

Crypto-economics characteristics :
  •   It isbased on the blockchain technology where each     block contains the hash of the previousblock and forms a continuous chain.
  • The particular state of transaction is impliedto change according to the transaction
  • The blockchain has to be immutable to add newblocks but the former blocks can’t be tempered with.
  • The blockchain should be downloadable and shouldbe easily accessible to anyone anywhere to check a particular transaction.


Cryptography or cryptology here is known for practicing and studying techniquesin order to secure communication in the presence of third parties calledadversaries. And Bitcoinis the decentralized digital crypto currency, a form of electronic cash, whichcan be sent from user to user on the peer-to-peer bitcoin network without theneed for intermediaries.


Itis a virtual currency, whose idea was implemented in 2008 by Satoshi Nakamoto,in his manifesto. Bitcoin was the first blockchain implementationcryptographically secures the data in the ledgers and most of the new systemand application are working on the basis of Bitcoin.

Blockchaindevelopers can be divided into two categories.

  • Core blockchain developer
  • Blockchain system developer.

Core blockchain developer isresponsible for the architecture of the system of blockchain, designing theprotocols and security patterns for the network and regulates the supervisionof the entire network.

Blockchain system developer, onthe other hand, uses these protocols and architecture to develop decentralisedapplication that proceeds on blockchain technology. Development of SmartContracts, interactive front end designs for Dapps (decentralisedapplications), backend development pertaining to Blockchain and supervision ofthe entire stack running their Dapps are the role that blockchain system developerdeals with.

Skills Required

Acombination of skills is expected by the person who aspires to becomea blockchain developer. Let’s discuss them one by one.

Blockchain architecture

One has to have the insights over theconstruction or the architecture of the technology and get familiarised withthe concepts like cryptographic hash functions, consensus, distributed ledgertechnology. And the best way is to go through the Bitcoin blockchainwhitepaper.

The process of becoming a networker isn’t considered for the faint-hearted. It requires lots of hard work and nice and trustworthy Juniper JN0 681 Dumps, like that offered at the ExamClubs, to clear this grueling exam.

Data structure

 Thecraftsmanship of architecture is coupled with the applied knowledge of datastructure. The developer has to tune the data constantly to meet their personalrequirements. A strong data structure added to the cryptography, builds asecure and immutable system.

Contractual development

 After the introduction of Ethereum,blockchains assimilate smart contractual functionality into its systems toapply business logics. It generally involves learning languages like Solidity Viper,Chaincode etc.

Web development

The most basic aspect of learning to be ablockchain developer is to get acquainted with the  basic designing of decentralizedapplications.

But even after knowing the main branches ofthis technology, how to work upon its practicality is a different thing.

For coming down to reality,  create your own account on any of theexchange services. It’s very simple for you don’t need to create an extensive portfolio straightaway. Get accessto any coinbase  and buy some coinsusing  basic online wallet to which youcan have access from any server or any device in the world while it’s connectedto the net. But store a minimum amount that you need for exchange purposebecause your private key is saved on another server and this is invitation forthe  hackers to prey.


 Asalready discussed, cryptography is the practice to shield the communication andnot letting third parties to intrude. And blockchain is created through thedata structure and cryptography. Having a great skill of this practice. It’s atechnique to convert the actual text into encrypted text that makes itdifficult to manipulate the information. The blockchain developer need to guardthe data and for that cryptography is the exquisite art that sets thistechnology from other modern innovations. Methods like hash functions eg SHA256and KECCAK 256 are the models of cryptography. 

Smartcontracts and Tools required

For creating Dapps and contracts, one needs toget familiar with the existing Dapps. There are numerous applications developedevery moment on Ethereum. The most popular Dapps are

DecentralizedExchanges (DEX) arebasically exchanges that allows the trading of cryptocurrency. It reduces therisk of theft from hacking of exchanges.The most popular DEX is Idex, but theyare other one like Bancor or the Token Store.

GamingDapps through which the userpurchases characters from the creator just like in the non blockchain games butthe difference lies on the economic phase where the player can easily andfreely  trade with other characters. Anexample of gaming Dapp would be Cryptokittis.

GamblingDapps, most of them, arebuilt as scams and have created a bad reputation. For instance, fomo 3D is avogue sample of this application.

Marketplace is a rare applicationon Ethereum and the marketplace of Decentraland would be an exquisite exampleof it.


Blockchain also needs coding to work or evento exist as it has to be a transparent ledger holding on to it’s quality ofbeing immutable and that’s what makes this technology credulous.

One of the most applied coding languages inBlockchain development is the one that you might have already studied atschool, which is C++. Bitcoin testaments to this statement because bitcoincore, the inner system of bitcoin is coded in C++. But the developer has toimbibe other languages as well to avoid becoming a gullible crafter. Ethereumis coded using an amalgamation of C++,Ruby, Python, Java, Go, Rust, JavaScript, etc.


This language packs data and its functionsinto ‘objects’, allows for effective management of resources and offers greatercontrol over memory. C++ creates applications that can not only coordinatebetween numerous endpoints but also process their interactions quickly. Forinstance, Solc is the compiler of the Solidity programming language written inC++.


Java has become one of the top 3 programminglanguages for blockchain development. Java programming language is useful increating highly interactive web pages and making simple and immutableblockchains.


The syntax and logic of this blockchainprogramming language uses reflects this very ambition of the creator. Pythonport of web3 is used forcommunicating Ethereum clients that has the ability to dynamically createabstractions (objects) that represent a smart contract.


This blockchain programming language ishigh-level and contract-based. This new language on the block, Solidity is inthe process of becoming popular now.Remixis an online IDE for Solidity smart contracts and  for writing Solidity code.

For encoding and decoding the transparent data, the blockchain developer has to know the language to code in, like c++ andjava.  These languages are not justapplied in creating applications for blockchain, but they also help in learningcontract-based or blockchain-based languages like Simplicity or Solidity.

What does the new kid on the block needs to have in store

We now know in what fields the blockchaindeveloper has to be good at. This technology is growing and changing day by dayso one has to be enthusiastic and passionate for learning new things.

  1. One’s brain should be well versed in regards to the programming languages that are needed to code the data.
  2. Knowledge for developing Dapps is essential.
  3. Well acquainted in creating smart contracts.

{Smart contractfunctionality needs to be three things:

Deterministic:- When you get the same output on every time on the singleset of inputs.
Terminable:- The contracts are supposed to get terminate at a particulartime limit. And there is a problem with the smart contracts that the programcan execute its function in a time limit, it’s called “halting problem”.

Isolated:- The technology is open to everyone to create contract that raises thepossibility of containing viruses and this may affect the whole system and itsmanagement. So it’s important to keep the contract safe and shielded from itsnegative effects. }

4. What qualities the companies are looking for in a blockchain developer is essential to know already.

5. Understanding of financial services, payment processing, credit services.

As it is considered secure and the operationcost is quite low it is quite a hit among the companies and even biggies likeIBM and Microsoft uses it and the rapid increase in demand for Blockchaintalent has led the technology to be the fastest growing skills among 5000skills in today’s market. Not only coding and encrypting, there also comeslegalities which come with any transaction that needs to be looked after by anattorney who knows how blockchain works, in other words, a Blockchain Attorney.The distributed ledger has lowered operational cost. Hence it is expected that companieswill require a lot of blockchain professionals for the transition from old tonew technology.

So what steps you have to focus on isunderstanding the basics,  learn how thetechnology and it’s aspects works, how languages like c++ and java helps tobuild your coding skills, to learn building smart contracts and having accessto industries that leads you to grow and define yourself as a blockchaindeveloper.


In coming 5 years blockchain development willbe the top areas in development. A lot has to be discovered in this field. Alot of execution has to take place in coming years. With the mentionedinformation, it might be useful for the aspirant blockchain developer. Theskills that you need to imbibe and career steps you can focus on are essentialinformation to look up to. This developing network needs passionate brains.This information can be very useful in you fine-tuning your skills enough toappeal to the companies.

Although no system is ever 100 percent protected, the ability for differentiating between typical network traffic as well as potentially harmful malware is considered crucial and provides the focus of this associate-level certification path. Also, if you wish to acquire this certification, you should gain the Juniper JN0-361 Dumps, which are being offered at the ExamClubs.
