A blockchain, originally block chain, is a growing list of records, called blocks, which are linked using cryptography.

Blockchains which are readable by the public are widely used by cryptocurrencies.

Private blockchains have been proposed for business use.

Some marketing of blockchains has been called "snake oil.".

A cryptocurrency (or crypto currency) is digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets.

Cryptocurrency is a kind of digital currency, virtual currency or alternative currency.

Cryptocurrencies use decentralized control as opposed to centralized electronic money and central banking systems.

The decentralized control of each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.

Cryptography or cryptology (from "hidden, secret"; and graphein, "to write", or -logia, "study", respectively) is the practice and study of techniques for secure communication in the presence of third parties called adversaries.

More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages; various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography.

Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, electrical engineering, communication science, and physics.

Applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications.
