What is Blockchain?
Blockchain technology has been gaining traction in recent years, with its potential applications seeming endless. From financial transactions to supply chain management, the possibilities are vast. However, mastering blockchain requires a deep understanding of its underlying principles and technologies.
A Brief History
The concept of blockchain dates back to 1991 when Stuart Habner and Wolfgang Ketterle proposed the idea of using cryptography for secure data transmission. The term ‘blockchain’ was first coined in 2008 by Satoshi Nakamoto, an anonymous individual or group who created the Bitcoin protocol.
How Does it Work?
In simple terms, blockchain is a decentralized ledger that records transactions across multiple nodes on a network. Each block contains data and a unique code called a ‘hash’ that connects it to the previous block, creating a chain of blocks (hence the name). This allows for secure, transparent, and tamper-proof record-keeping.

* Nodes: These are the computers that make up the network and verify transactions.
* Consensus mechanisms: This is how nodes agree on the state of the ledger, ensuring its integrity.
Applications
Blockchain technology has numerous applications across various industries. Some examples include:
* Financial services: Secure and transparent payment systems
* Supply chain management: Tracking goods from production to delivery
* Healthcare: Securing patient data and medical records
