Frequently asked questions

What is the difference between a blockchain and a normal database?

A normal database usually sits with one organisation, which can edit or delete rows at will. A blockchain is copied across many independent computers that must agree before anything is added, and older entries are chained together so altering one would visibly break the rest.

Is a blockchain the same as a cryptocurrency?

No. A blockchain is the record-keeping system; a cryptocurrency is a kind of digital money whose balances are recorded on one. A blockchain can just as easily hold records of documents, votes or shipments.

Can anything on a blockchain be deleted?

On a typical public blockchain, entries are append-only: new records are added rather than old ones edited, and the chained structure makes past entries very difficult to alter once many computers have accepted them. Private or permissioned systems may set different rules.
