How does block chain technology work?
Block chain technology is a decentralized and distributed ledger that is used to record transactions and store data. The key feature of block chain is that it allows for secure and transparent transactions between parties without the need for intermediaries such as banks or financial institutions.
At its core, a block chain is a chain of blocks, where each block contains a set of transactions. Each block is linked to the previous block in the chain, forming a continuous chain of blocks. This creates an unbreakable chain of records that can be used to verify the integrity of the data.
The process of adding a block to the block chain involves a consensus mechanism that requires agreement from the network of participants. This ensures that all parties agree on the transactions recorded on the block chain and prevents fraudulent or malicious activity.
To achieve this consensus, the block chain network uses a system of cryptography and complex algorithms to verify and validate each transaction. This involves a process called mining, where nodes in the network compete to solve complex mathematical problems and add new blocks to the chain. The first node to solve the problem is rewarded with new crypto currency tokens or transaction fees.
The decentralized nature of block chain technology means that no one entity controls the network, making it resistant to fraud, corruption, and hacking. This makes block chain technology an attractive solution for many industries, including finance, supply chain management, and healthcare, among others.
