At the heart of every cryptocurrency lies blockchain technology. A blockchain is a distributed digital ledger that records all transactions across a network of computers (nodes).
Each transaction is grouped into a “block,” and once verified, the block is added to a chain of previous blocks—hence the name blockchain.
