Do you want to become a Blockchain Developer? Here we are sharing complete information about Blockchain developers. With the help of this detailed guide, you will be able to know what is its demand right now, what you need to do to become a successful blockchain developer, how much salary will you get.

What is Blockchain?

  • A blockchain is a decentralized public digital ledger consisting of blocks used to record transactions across multiple computers (nodes).
  • In the blockchain, blocks are linked together using cryptography.
  • Each block contains the cryptographic hash, timestamp, and transaction data of the previous block.
  • The blockchain database is managed autonomously using a peer-to-peer network and a distributed timestamping server.
  • When the transaction completes it creates a new block to store it in the digital ledger. Identifying when this transaction took place, saves the time of the transaction, which is called timestamp.
  • When the transaction completes it creates a new block to store it in the digital ledger. Identifying when this transaction took place, saves the time of the transaction, which is called timestamp. Each block is linked with the block before it and it also holds information about the previous transaction, so they form a chain by creating blocks. Each additional block strengthens the block before it. If someone wants to change the data of any block, then he will have to change the data of all the other blocks. But it is not possible to replace every block. So the data is secure in the blockchain.
  • It allows participants to verify and audit transactions independently and relatively inexpensively.

What is the demand for blockchain in various sectors?

The demand for blockchain is going to be high in the future days. There are so many opportunities for professionals in this industry. Blockchain technology can be used in many fields. Such as:

1. Business

Some businesses are testing this technology in their back offices to measure their organizational efficiency. But many companies are already using Blockchain to improve their efficiency, build trust, rapidly scale and size many solutions.

For example, IBM is using the Hyperledger Blockchain creator tool to create its own distributed ledger and smart contracts. Like IBM, other big companies also use blockchain. The few names of companies are Walmart, Amazon, FedEx, Microsoft, Baidu, etc.

2. Cryptocurrencies

Most cryptocurrencies use blockchain technology to record transactions. As both bitcoin and Ethereum networks are based on blockchain. On 8 May 2018, Facebook also confirmed that it would be opening a new blockchain group.

3. Smart Contract

Before understanding the smart contract, let us tell you about the contract. A contract is an agreement between two people, which is legally enforceable. Every action in this is taking place with the permission of both the people.

A smart contract is a coding form of contract. This agreement between the two people is set up in the blockchain in the form of computer code. When a transaction takes place, it gives permission in a few moments as per the agreement. It does not require any third-party interaction and no one can change it.

Smart contracts will also be needed in every area where a transaction takes place on the blockchain. No transaction would be possible without a smart contract.

4. Banks & finance

Blockchain is a digital ledger that will be useful more in the field of banking and finance sector. With the help of blockchain, banks will send and receive payments rapidly. Being smart contracts, they can perform secure transactions from multiple data points without anyone’s interaction.

Several banks have expressed interest in implementing distributed ledgers for use in banking. They are collaborating with private blockchain companies.

5. Healthcare

Healthcare providers can use blockchain technology to securely store the medical records of their patients. When a medical record is created, it will be stored in the blockchain. This will be useful to patients, assuring them that their records cannot be changed and that it is secure in the blockchain.

In addition, blockchain can be used in many fields such as games, property records, currency, voting, etc.

Who is the Blockchain Developer?

A blockchain developer is a professional who will create and manage decentralized applications on the blockchain for clients. The day-to-day work of a blockchain developer includes:

  • Designing the blockchain security protocols and the architecture of blockchain data
  • Backend and front-end development for clients
  • Responsible for the research and execution of the Dapps (Decentralized applications)

There are two types of blockchain developers and their responsibility of work areas are different.

1. Core Blockchain Developer

A Core Blockchain Developer forms the foundation of the blockchain data system. The responsibility of the developer is to design the security protocols of the blockchain network, and architecture of the blockchain data, and supervise the same.

2. Blockchain Software Developer

A Blockchain Software Developer’s responsibility is to create decentralized applications, implementing smart contacts using the design and protocol created by the core blockchain developer.

What are the roles and responsibilities of a blockchain developer?

2. Learn cryptography

Cryptography is of study technique for secure communication. It helps in constructing and analyzing protocols to protect unwanted parties from accessing data.

By learning cryptography, you will be able to prevent your data from unwanted accessing of your data.

3. Learn blockchain architecture

Blockchain architecture is designed to manage valuable data such as when a transaction takes place, the amount of the transaction, and who sends or receives the transaction. The blockchain architecture supports a growing list of ordered records known as blocks. Each block maintains a timestamp and a link to the previous block.

To become a blockchain developer, you should know about blockchain architecture. You should know what is a block, node, transaction, chain, mining, Consensus (protocol).
