You may never become a better blockchain developer if you don’t read this.

You’re probably wondering why I used that kind of header. Well, I wanna catch your attention.

Why Should you read this if I want to become a better blockchain developer? You’ll be getting to understand the concept of cryptography if you read this article it’ll give you an edge as a blockchain developer.

Let’s Dive in.

What is Cryptography?

is the process of hiding or coding information so that only the person a message was intended for can read it.

Imagine, I want to send you a text and I don’t want anyone to get to know about the content except for you who is the receiver.

I would encrypt such a message and it’ll be decrypted by you once you get it.

Where am I going with this?

I’m trying to explain to you the use of cryptography in blockchain.

But first, let’s define blockchain.

A blockchain is a decentralized and unchangeable record in which information is being kept.

Now that you know what the blockchain is, it’s time for you to understand the role of cryptography in blockchain technology.

→ Public & Private Keys

These keys are fundamental cryptographic elements in the blockchain.

Public keys are like our email addresses which allow us to receive crypto assets from users on the blockchain,

While private keys are like passwords granting us access to the assets.

→ Blockchain Hash Functions

Data is transformed into fixed-length character strings using hash functions, a type of cryptographic instrument.

→ Consensus Mechanism

Achieving consensus among users is important in a blockchain network.

This consensus is facilitated by the use of cryptographic techniques, which guarantees that all network nodes concur on the legitimacy of transactions.

Both Proof of Stake (PoS) and Proof of Work (PoW), two well-known algorithms, largely rely on cryptographic concepts.

→ Smart Contracts

Smart contracts are agreements that automatically carry out the instructions given to them because they are encoded in code.

By using cryptography, their security and reliability are guaranteed.

You can interact with these contracts with confidence knowing that the results have been established and the code is impenetrable.

I’ve just given you the major reasons cryptography is important in blockchain technology.

Now it’s left to you to utilize this knowledge
