Web3 Explained

A blockchain is a digital, decentralized, distributed ledger that is used to record transactions across a network of computers. It consists of a series of interconnected blocks, each containing a record of multiple transactions. Each block is cryptographically linked to the previous block, forming a chain of blocks that cannot be altered. The main advantage of using a blockchain is that it allows for secure and transparent record-keeping without the need for a central authority or intermediary.
