Understanding Blockchain Technology

What is Blockchain Technology?

At its core, blockchain technology is a distributed ledger that records transactions across a network of computers. Each transaction is grouped into a block, which is then appended to a chain of previous blocks, forming a secure and immutable ledger. The decentralized nature of blockchain ensures that no single entity controls the entire system, enhancing transparency and reducing the risk of fraud.

How Does Blockchain Work?

1. Transaction Initiation: A transaction is initiated by a user, typically involving the transfer of assets or information.
2. Transaction Verification: The transaction is broadcasted to a network of nodes (computers) that validate the transaction based on predefined rules.
3. Block Creation: Validated transactions are grouped into a block.
4. Consensus Mechanism: The network reaches a consensus on the validity of the block through mechanisms such as Proof of Work (PoW) or Proof of Stake (PoS).
5. Block Addition: Once verified, the block is added to the blockchain, and the transaction is considered complete.
6. Ledger Update: The updated blockchain is distributed across all nodes in the network, ensuring consistency.
