The blockchain is a shared public ledger on which the entire Bitcoin network relies

in #success2 years ago

All confirmed transactions are included in the block chain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and chronological order of the block chain are enforced with cryptography.

A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin miners help keep the Bitcoin network secure by approving transactions. Mining is an important and integral part of Bitcoin that ensures fairness while keeping the Bitcoin network stable, safe and secure.
