**Introduction**

Welcome to Day 1 of the 14-week journey into the world of crypto! Whether you’re a curious beginner or someone looking to sharpen your skills, this series will guide you through everything you need to know. Let’s start by laying the foundation: understanding blockchain. This technology underpins every cryptocurrency and is the key to grasping how the crypto world operates.

Let’s dive into the basics and make sense of this revolutionary technology.

---------------------------------------------------------------------------------------------------

**What is Blockchain?**

Imagine a digital ledger that records transactions in a way that’s secure, transparent, and tamper-proof. This is the essence of blockchain. But how does it work?

​

**Blocks and Chains**

•	A blockchain is made up of _blocks_, which are chunks of data containing transaction information.

•	Each block is linked to the previous one, forming a _chain_. Hence, the name: blockchain.

**Decentralisation**

•	Unlike traditional systems that rely on a central authority (like banks), blockchains operate on a network of computers (called nodes) spread across the world.

•	Every node has a copy of the entire blockchain, ensuring transparency and preventing single points of failure.

**Immutability**

•	Once a block is added to the chain, it’s virtually impossible to alter its contents. This makes blockchain highly secure.

Blockchain technology has the potential to revolutionise industries beyond finance. Here’s why it’s so impactful:

•	**Transparency:** Every transaction is visible to all participants in the network.

•	**Security:** Advanced cryptographic techniques make it nearly impossible to hack.

•	**Efficiency:** Transactions can be processed faster and cheaper compared to traditional systems.

**Real-Life Applications of Blockchain**

While blockchain is most commonly associated with cryptocurrencies like Bitcoin and Ethereum, its applications extend far beyond. Here are a few examples:

1. **Finance**: Facilitates peer-to-peer transactions without intermediaries.
 
2. **Supply Chain**: Tracks goods from origin to consumer, ensuring transparency and reducing fraud.
 
3. **Healthcare**: Safeguards patient records and ensures data integrity.
 
4. **Voting**: Provides a secure and transparent method to conduct elections.

**Key Takeaways**

1. Blockchain is a decentralised, immutable ledger that records transactions.
 
2. It ensures transparency, security, and efficiency in various industries.
 
3. Understanding blockchain is crucial for anyone entering the crypto space.
