Introduction to Blockchain
Blockchain is essentially a distributed ledger; it’s like a digital record-keeping system that is spread across many computers. This means that every transaction that occurs on this ledger is recorded on multiple computers across the world. Due to its decentralized nature, it isn’t owned or controlled by a single entity, making it transparent and potentially more secure than traditional centralized systems.
Think of a blockchain as a chain of digital “blocks” that contain records of transactions. Each block is connected to the ones before and after it, creating an irreversible timeline of data when implemented in a decentralized nature. Transactions are approved by consensus — an agreement by several parties — so everybody with access has a say.
Why does this matter for you? Well, blockchain’s decentralized and consensus-driven approach means that:
- You don’t have to rely on a central point of control.
- Your transactions are, by design, audited by a crowd — the network of users.
Blockchain technology isn’t just for cryptocurrencies like Bitcoin or Ethereum. It’s a broad technology that can be used for a variety of applications, such as supply chain management, digital identity verification, and more.
| Advantages | Disadvantages |
