Blockchain and Cryptocurrencies Blockchain: A blockchain is a decentralized and distributed ledger that records transactions across a network of computers. It consists of a chain of blocks, each containing a list of transactions. Transactions are grouped into blocks through a process called mining, where participants in the network solve complex mathematical problems to add a new block to the chain. Once a block is added, it is cryptographically linked to the previous block, forming a secure and transparent chain of transactions. Blockchain technology provides a tamper-resistant and transparent record of transactions, eliminating the need for a central authority to validate and authenticate transactions. Cryptocurrencies: Cryptocurrencies are digital or virtual currencies that use cryptography for security and operate on decentralized network...
