Basic explanation of blockchain
Blockchain technology is a digital ledger that records transactions in a secure and transparent manner. Each block in the blockchain contains a digital record of a transaction or other piece of data, along with a unique code called a hash. The hash of each block is used to link it to the previous block in the chain, creating an unbroken chain of blocks that cannot be altered without affecting all subsequent blocks. Instead of relying on a centralized authority, like a bank or government, blockchain transactions are validated by a decentralized network of nodes. Each node has a copy of the ledger, which is constantly updated and verified by the network.
One of the most well-known applications of blockchain is in cryptocurrency, such as Bitcoin and Ethereum. However, blockchain can also be used for a variety of other applications, such as supply chain management, ownership of assets, voting systems, storing medical records, and digital identity verification.
