How Blockchain Works: A Detailed Explanation
Blockchain technology has gained immense popularity in recent years, primarily due to its association with cryptocurrencies like Bitcoin and Ethereum. However, its potential extends far beyond digital currencies, promising to revolutionize industries ranging from finance and supply chain management to healthcare and voting systems. In this <a href=https://www.google.com></a>Text6</a> article, we will explore what blockchain is, how See More it works, and the various applications that can benefit from its decentralized and secure nature.

Blockchain can be understood as a digital ledger that records transactions in a way that is secure, transparent, and resistant to tampering. Unlike traditional databases, where data is stored centrally, a blockchain is decentralized and distributed across multiple computers (nodes) in a network. Each transaction or data entry is stored in a "block," and these blocks are linked together in a chronological order, forming a "chain."
How Does Blockchain Work?
Blockchain operates on a decentralized network, where each participant (or node) maintains a copy of the entire blockchain. The process of adding new data to the blockchain involves several key steps:
A user initiates a transaction by submitting it to the blockchain network. This could be a financial transaction, the transfer of assets, or the creation of a smart contract. The transaction contains the details of the exchange, such as the sender, receiver, and amount.
Before a transaction is added to the blockchain, it must be verified by the network. In a public blockchain, this is typically done by a process known as consensus. Different consensus mechanisms, like Proof of Work (PoW) or Proof of Stake (PoS), are used to validate the transaction. For example, in Bitcoin's Proof of Work system, miners solve complex mathematical problems to verify transactions, while in Ethereum's Proof of Stake, validators stake their tokens to participate in the verification process.
Once verified, the transaction is grouped with other transactions into a new block. This block is then added to the chain. Each block contains a unique cryptographic hash of the previous block, which links them together. This creates an immutable record, ensuring that any changes to one block would require altering all subsequent blocks, which would be computationally infeasible.
