how blockchain technology works in cryptocurrency
In blockchain technology, the verification and addition of transactions to the chain involves a decentralized network of nodes, safeguarding the integrity and immutability of data by using a cryptographic hashing algorithm and a consensus mechanism.

How Blockchain Technology Works in Cryptocurrency
- Decentralized Network:
A blockchain is a decentralized network, meaning it is not controlled by a single entity, such as a bank or government. Instead, it is maintained by a network of computers distributed across the globe, known as nodes. - Transaction Data:
The blockchain stores transaction data in blocks, which are linked together in a chronological order. Each block contains a hash of the previous block, creating an immutable chain of records. - Cryptographic Hashing:
Transactions are recorded using cryptographic hashing algorithms, which generate a unique code for each transaction. The hash ensures the data cannot be altered or tampered with once it has been included in a block. - Verification and Consensus:
When a new transaction is initiated, it is broadcasted to the network nodes. The nodes verify the transaction based on predefined rules (e.g., sender balance, signature validity). If a majority of nodes approve the transaction, it is added to the next block. - Block Addition:
Once the transaction is verified, it is added to the blockchain by a process called mining. Miners compete to solve a complex mathematical puzzle to add the block to the chain, receiving a crypto reward for their successful completion. - Transparency and Security:
Because the blockchain is publicly viewable, all transactions are auditable and transparent. The distributed and cryptographic nature of the blockchain makes it extremely secure, as alterations require consensus from a majority of nodes. - Smart Contracts:
Blockchain technology also enables the creation of smart contracts, automated programs that execute specific actions when predefined conditions are met. These contracts can be used to streamline complex processes and reduce the need for intermediaries.
