Understanding Blockchain Technology
Definition and Basic Concepts
A blockchain is like a digital notebook that everyone can see but no one can change. Imagine writing down information in a notebook, and every time you write a new page, you also write a special code (called a hash) that represents everything on the previous page. This way, if someone tries to change something, the code won’t match anymore, and everyone will know it’s been tampered with.
In simple terms, a blockchain is a shared database where information is stored in blocks that are linked together. Each block contains a list of transactions, and once a block is full, it gets added to the chain.
How Blockchain Works
Here’s how a blockchain operates in a few easy steps:
- Transaction Initiation: Someone wants to make a transaction, like sending money.
- Verification: The transaction is sent to a network of computers (called nodes) that check if it’s valid.
- Block Creation: If valid, the transaction is grouped with others into a block.
- Hashing: A unique code (hash) is created for the block, linking it to the previous block.
- Adding to the Chain: The new block is added to the existing chain, and everyone in the network updates their copy.
Key Features of Blockchain
Some important features of blockchain include:
- Decentralisation: No single person or group controls the blockchain; everyone has a copy.
- Immutability: Once information is added, it cannot be changed or deleted.
- Transparency: Everyone can see the transactions, making it hard to hide anything.
Blockchain technology is a powerful tool that can change how we handle information and transactions. It offers a secure and transparent way to keep records, which is why it’s gaining popularity in various fields, including finance and supply chain management. As noted by Jon Horvath, the rise of Bitcoin in 2017 showcased the potential of this technology, with its price soaring from a few hundred dollars to $20,000, providing significant returns for early investors.
