How Blockchain Works

The blockchain is a decentralized ledger technology that allows secure transfer and storage of data. It operates on a peer-to-peer network, where each participant holds a copy of the ledger, which is verified through consensus algorithms. Each block in the chain contains cryptographic hashes, linking it to the previous one, making it an immutable record.

Transactions are verified and added to blocks through complex mathematical algorithms that require significant computing power, which creates an incentive for participants to keep the network running known as mining. Once a block is validated, it is broadcasted to the network, ensuring transparency and accountability.

Additionally, blockchain’s design ensures that data cannot be tampered with or altered once added to the chain. This feature makes it useful in industries like finance and healthcare for secure and transparent record-keeping.

According to Forbes, over 50% of Fortune 500 companies are either researching or using blockchain technology in their operations, highlighting its growing importance in modern-day business infrastructure.
