What is blockchain?

The blockchain is an #immutable #distributed digital ledger with many use cases beyond #cryptocurrencies (#digital_currencies secured by #cryptography).

In other words, a blockchain is a database (ledger) that structures its data in chunks (blocks) that are chained together. This system also inherently makes an irreversible timeline of data when implemented in a #decentralized nature.

?When a block is filled it is set in stone and becomes a part of this timeline. Each block in the chain is given an exact timestamp when it is added to the chain.

Immutable and distributed are two fundamental blockchain properties that I will discuss in the next article.
