Blockchain Basics – A Non-Technical Introduction in 15 Steps

Blockchain technology has been making waves in the world of finance, technology, and beyond in recent years. While it can be difficult to understand at first, blockchain has the potential to change the way we interact with information, money, and each other. In this article, we will provide a non-technical introduction to blockchain in 15 steps. But before we dive in, let’s introduce Profit Edge, an online trading platform that allows users to buy and sell cryptocurrencies with ease.

Step 1: What is blockchain?

At its core, a blockchain is a distributed ledger technology that allows for secure, transparent, and decentralized transactions. Rather than being owned and managed by a central authority, a blockchain is managed by a network of computers around the world.

Step 2: Why is blockchain important?

Blockchain has the potential to revolutionize many industries by providing a secure and transparent way to track and transfer information and assets. It can be used for everything from tracking supply chains to voting systems.

Step 3: How does blockchain work?

A blockchain is made up of a series of blocks, each containing a set of transactions. These blocks are linked together in a chain using cryptography, creating an immutable record of all transactions.

Step 4: What is cryptography?

Cryptography is the practice of using mathematical algorithms to secure information. In the context of blockchain, cryptography is used to create secure, tamper-proof transactions.

Step 5: What is a decentralized network?

A decentralized network is a network that is not controlled by a central authority. In the context of blockchain, a decentralized network is made up of computers around the world that work together to maintain the integrity of the blockchain.

Step 6: What is a smart contract?

A smart contract is a self-executing contract with the terms of the agreement between buyer and seller being directly written into lines of code. They are stored on the blockchain and automatically execute when certain conditions are met.

Step 7: What is a cryptocurrency?

A cryptocurrency is a digital or virtual currency that uses cryptography for security. It operates independently of a central bank and can be transferred and traded without the need for a third party.

Step 8: What is Bitcoin?

Bitcoin is the first and most well-known cryptocurrency. It was created in 2009 by an unknown person or group using the pseudonym Satoshi Nakamoto. Bitcoin operates on a decentralized network and uses blockchain technology to track transactions.

Step 9: What is mining?

Mining is the process of adding new blocks to the blockchain. In order to do this, miners use specialized computers to solve complex mathematical problems. The first miner to solve the problem is rewarded with a certain amount of cryptocurrency.

Step 10: What is a node?

A node is a computer that is connected to a blockchain network. Nodes work together to maintain the integrity of the blockchain by verifying transactions and adding new blocks to the chain.

Step 11: What is a private key?

A private key is a secret code that is used to access and manage a user’s cryptocurrency holdings. It is important to keep private keys secure, as anyone who has access to them can access the user’s funds.

Step 12: What is a public key?

A public key is a code that is used to receive cryptocurrency. It is safe to share a public key with others, as it does not give them access to the user’s funds.

Step 13: What is a wallet?

A wallet is a digital storage space that is used to store cryptocurrency. It can be thought of as a digital bank account.

Step 14: What is a block explorer?

A block explorer is a tool that allows users to view information about blocks and transactions on the blockchain.

Step 15: What is a consensus mechanism? 

A consensus mechanism is a method used by blockchain networks to ensure that all nodes on the network agree on the state of the blockchain. There are several different consensus mechanisms, including Proof of Work (PoW) and Proof of Stake (PoS).


Blockchain technology has the potential to transform the way we interact with information, assets, and each other. While it may seem daunting at first, understanding the basics of blockchain can provide a solid foundation for exploring its potential applications. Whether you are a blockchain enthusiast or just curious about this emerging technology, we hope this non-technical introduction has been helpful.
