What is the Bitcoin Blockchain?

So next time someone asks you, "Where is the central Bitcoin database?" you can confidently explain the decentralized nature of Bitcoin and the revolutionary technology behind it.

The "Bitcoin database" is not a traditional office 365 email list database in the sense of a centralized server storing information. Instead, it refers to the Bitcoin blockchain, which is a decentralized, distributed public ledger that records all Bitcoin transactions.


Blocks: Imagine a page in a ledger. Each block contains a bundle of verified Bitcoin transactions.
Chain: These blocks are cryptographically linked together in a chronological sequence, forming a "chain." Each new block contains a cryptographic "hash" (a unique digital fingerprint) of the previous block, creating an unbreakable link. If any data in an older block were altered, its hash would change, breaking the chain and immediately signaling tampering to the network.
