Bitcoin is a digital currency or cryptocurrency, while blockchain is the technology that powers it.
Bitcoin is a decentralized digital currency that can be used to send and receive payments directly between two parties. It is based on a distributed ledger technology called blockchain, which is a secure, tamper-proof digital ledger that records and stores all Bitcoin transactions.
Blockchain, on the other hand, is a distributed ledger technology that forms the basis of Bitcoin and other digital currencies. It is a decentralized, secure, and immutable digital ledger that records and stores all transactions across a peer-to-peer network. It is a public ledger that is shared among all participants in the network, which makes it difficult to tamper with.
For example, when someone sends a Bitcoin transaction, it is recorded on the blockchain and can be seen by all participants in the network. This ensures that the transaction is secure and that the funds are sent to the right person.
