Understanding Blockchain

Blockchain technology is a type of distributed ledger technology that allows data to be stored globally on thousands of servers. Here’s a simplified explanation of how it works:

Transaction: Every transaction starts with a user who initiates the process. This could be a cryptocurrency exchange, a data transfer, or any other type of transaction.
Block Creation: Once a transaction is initiated, it is grouped together in a block with other transactions that have occurred in the last ten minutes and sent out to the entire network.
Verification: Miners (nodes in the network) then validate the transactions within the block. They do this by solving complex mathematical problems.
Adding to the Chain: Once the block of transactions has been verified, it is added to the blockchain. The block is given a hash (a unique string of numbers and letters), timestamped, and added to the blockchain in a linear, chronological order.

Now, let’s look at the key features of blockchain:

Decentralization: Unlike traditional databases, where data is stored on a central server, blockchain operates on a network of computers, each having an identical copy of the blockchain. This means that no single entity has control over the entire network, making it decentralized.
Transparency: Every transaction on the blockchain is visible to anyone who has access to the system. This transparency can help reduce fraud and corruption.
Security: Once a block is added to the blockchain, it is extremely difficult to change or tamper with. This immutability makes blockchain a secure way to store and transfer data.

These features make blockchain a powerful tool for a variety of applications beyond just cryptocurrencies. In the following sections, we will explore some of these applications.
