1. Key Components of Blockchain :

Blocks - Stores transaction data and metadata.

Chains - The blocks are linked together using hashes, forming a chain.

nodes - A computer in the network that stores, verifies, or shares blockchain data.

decentralization - control is shared among many nodes, not one central authority and increase security

2. Types of Blockchain :

Types of Blockchain / Meaning	Benefit	Limitation
Public - Anyone can join and view the blockchain	High transparency	Can have slower transactions
Private - Access is restricted to authorized users or an organization	More privacy and faster transactions	Less decentralized
Consortium - Controlled by a group of organizations rather than one organization	Shared control and efficiency	Requires agreement between organizations

3. Blockchain Applications :

Applications	Meaning	Examples
Finance	Use for cryptocurrency and digital payments ( secure money transactions)	Bitcoin allows people to transfer digital money without a traditional bank.
Supply Chain	Use to records the movement and history of products.	A supermarket can use blockchain to track a product from the farmer to the customer, making its origin and movement easier to verify.

These two connected when finance records the payment, while supply chain records the product's movement. Blockchain can securely record both.
