What is Blockchain?
Blockchain is a kind of technology that stores data in units called blocks. Each block holds transactions. When a block fills up, it gets sealed off. It then links to the last block using special coding, making a chain. This makes the data safe and hard to change without altering every block after it.
Key Features of Blockchain
Blockchain technology stands out for several reasons:
- Decentralization: Data isn’t kept in one place but is shared across many computers. This makes it very secure.
- Transparency: Every person in the network can see all the data, which builds trust.
- Immutability: Once data is added to the blockchain, it can’t be changed, keeping records safe.
- Security: Special coding methods keep the data safe from hackers and unauthorized changes.
Types of Blockchains
There are different kinds of blockchains, tailored for varied needs and access levels:
- Public Blockchains: Anyone can join these, and they are fully decentralized. Bitcoin and Ethereum are good examples.
- Private Blockchains: These are for specific people, offering more control and privacy. They work well inside an organization.
- Consortium Blockchains: A group of organizations manages these. They mix decentralized and centralized control. They’re good for businesses working together.
