Review
A blockchain is a decentralized, distributed, and secure digital ledger. It records transactions across many computers, making it very difficult to alter or hack. This innovative technology forms the foundation for cryptocurrencies like Bitcoin and also supports various other applications requiring transparent and tamper-proof record-keeping. Each block in the chain contains a timestamp and transactional data, and once validated, it’s permanently linked to the previous blocks, creating an immutable history. This distributed ledger technology ensures data integrity and trust without a central authority.
