It is used to store and verify a large volume of data efficiently and securely and used by the Bitcoin protocol to calculate the Merkle root of all transactions contained in a data block.

- 1990: American mathematician David Chaum invents DigiCash an electronic currency (centralized and proprietary) based on cryptographic protocols.
