What is blockchain technology?

Blockchain is a revolutionary technology that allows digital information to be distributed but not copied. It was originally designed for the cryptocurrency Bitcoin, but now it has found applications in various other industries as well.

How does it work?

Blockchain is a chain of blocks that contains data. Each block includes a hash of the previous block, a timestamp, and the transaction data. Once the block is completed, it is added to the chain in a linear, chronological order. This makes it nearly impossible to alter the data contained in the blocks without altering all subsequent blocks, which would require a majority of the network's computational power.

Key features and benefits

• Decentralization: There is no central authority governing the blockchain, making it a decentralized system.
• Transparency: All transactions are publicly recorded and can be viewed by anyone.
• Security: The data on a blockchain is secure due to its cryptographic nature.
• Immutability: Once data is recorded on a blockchain, it cannot be changed, providing a high level of integrity.
• Efficiency: Transactions on a blockchain are faster and more cost-effective compared to traditional systems.

Overall, blockchain technology has the potential to revolutionize industries by providing trust, transparency, and security in transactions and data sharing.
