Understanding Blockchain Technology

What is Blockchain?

At its core, blockchain is a distributed ledger technology (DLT) that allows multiple parties to maintain a shared record of transactions. This record is not stored in a single location, but rather across a network of computers, making it resistant to manipulation and fraud. Each block in the chain contains a list of transactions, a timestamp, and a link to the previous block.

Key Features of Blockchain

Decentralization: Unlike traditional databases controlled by a single entity, blockchain distributes data across a network, enhancing security and reducing the risk of single points of failure.
Transparency: Transactions recorded on a blockchain are visible to all participants in the network, fostering trust and accountability.
Immutability: Once data is added to the blockchain, it cannot be altered or deleted without consensus from the network, ensuring data integrity.
Security: Blockchain employs cryptographic techniques that secure data, making it extremely difficult to tamper with.
