Blockchain-based cryptocurrencies are digital currencies that use blockchain technology to record, verify, and secure transactions without needing a central authority like a bank or government.
A blockchain is a decentralized, distributed ledger that records data (like transactions) across a network of computers in a secure and tamper-resistant way.
A cryptocurrency is a digital form of money that:
Is built on a blockchain,
Uses cryptography to secure transactions,
Is typically decentralized (no single point of control),
Can be sent peer-to-peer, without needing a middleman.
