Who is a Blockchain Developer?

A Blockchain Developer is someone who:
Develops distributed
applications and smart
contracts
WHO IS A
BLOCKCHAIN DEVELOPER?

Designs, implements and
supports a Blockchain network

Creates and optimizes
Blockchain protocols

applications and smart
contracts on the Blockchain
Network
Creates and optimizes
Blockchain protocols

Blockchain Developers fall under two categories:
Core Blockchain

A core Blockchain Developer works very
similarly to how a core web developer works.
Both of them work with core concepts!

Blockchain Software

Blockchain Software Developers are similar to
Web application developers. Both of them create
applications on a network that’s set up by the
core developers

How do you become a Blockchain Developer?
Before you start off on your path to
become a Blockchain Developer, there
are a few things you absolutely have to
know!

Programming
Languages

Programming
Languages
Being well versed in programming languages is
important because most Blockchains are created
in languages like:
Java C++ Java Script GO
Python C Sharp

For core Blockchain Development, any
of the aforementioned languages can
be used for coding purposes…

But for software development (like
distributed applications and smart
contracts) on Ethereum, you’ll need to
learn the programming language
Solidity

Fundamentals of

Programming
The concepts of Object Oriented Programming
(which is the wrapping up of data and functions into
a single unit) are what Blockchains function on!
For example:
Ethereum

User Details (data)
Commands to send and
receive
payments(function)

Blockchain was borne out of the concepts of Flat and
Relational Databases
Flat databases store
data in a single table
structure
A relational database uses a
number of tables and cross
referencing records across
tables

It is important to learn the understand data
structures like:
• Stack,
• Linked list
• Queue, etc.
…because Blockchain is a back-linked list of blocks
that hold transactions
Each block is able to reference the block before it in
the “previous hash” field in its header

Now that the perquisites are out of the way, let’s
go into the steps you have to follow to become a
Blockchain Developer!

Prerequisites
Step 2
Step 3
Step 4
Step 1: The
concepts of
Blockchain

Step 3
The first step is to understand the basics of Blockchain
1
The concepts of Bitcoin and Blockchain are explained in
Satoshi Nakamoto’s white paper
Bitcoin- A Peer-to-Peer Electronic Cash System

Step 3
1
Learn important terms related to Blockchain like – Public
Distributed Ledger, Hash Encryption,
Proof of Work and Mining

Step 3

Step 4
Learn important terms related to Blockchain like – Public
Distributed Ledger, Hash Encryption,
Proof of Work and Mining
Learn how systems like Ethereum, Hyperledger, Hashgraph
and other systems that use Blockchains work

Prerequisites
Step 1: The
concepts of
Blockchain
Step 2: Understand the
economics behind
cryptocurrencies and
Blockchains
Step 3
Step 4

The second step is to understand how Blockchains help with crypto-
economics and cryptocurrencies
2 Blockchain technologies work on crypto-economics

Cryptography in Blockchains involves Hashing, Digital Signatures and
Proof of Work

Proof of Work
Hashing in cryptocurrencies is
made possible using
cryptographic algorithms
(SHA256 in Bitcoin and Ethash
in Ethereum)

Digital Signatures are
created using a combination
of users’ Private and Public
Keys
Proof of Work requires a
miner to solve a
mathematical puzzle to be
able to add a block to the
Blockchain

On the economics side, to understand how miners are incentivized
The users who add and take
part in the Blockchain are given
cryptocurrencies

cryptocurrencies
People who make decisions also
have the right to charge a fee for
their service

cryptocurrencies

Good users of the network are
rewarded monetarily or the
ability to take decisions
