A blockchain – originally block chain – is a distributed database that maintains a continuously growing list of ordered records called blocks.

Each block contains a timestamp and a link to a previous block.

By design, blockchains are inherently resistant to modification of the data — once recorded, the data in a block cannot be altered retroactively.

Through the use of a peer-to-peer network and a distributed timestamping server, a blockchain database is managed autonomously.

Blockchains are "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way.

The ledger itself can also be programmed to trigger transactions automatically.".

The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide.

It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies.

The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and peer-to-peer networks for file sharing.

English is a West Germanic language that was first spoken in early medieval England and is now the global lingua franca.

Named after the Angles, one of the Germanic tribes that migrated to England, it ultimately derives its name from the Anglia (Angeln) peninsula in the Baltic Sea.

It is most closely related to the Frisian languages, although its vocabulary has been significantly influenced by other Germanic languages in the early medieval period, and later by Romance languages, particularly French.

English is either the official language or one of the official languages in almost 60 sovereign states.

It is the most commonly spoken language in the United Kingdom, the United States, Canada, Australia, Ireland, and New Zealand, and is widely spoken in some areas of the Caribbean, Africa, and South Asia.

It is the third most common native language in the world, after Mandarin and Spanish.

It is the most widely learned second language and an official language of the United Nations, of the European Union, and of many other world and regional international organisations.

It is the most widely spoken Germanic language, accounting for at least 70% of speakers of this Indo-European branch.

Cryptography or cryptology (from Greek kryptós, "hidden, secret"; and graphein, "writing", 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, and electrical engineering.

Applications of cryptography include ATM cards, computer passwords, and electronic commerce.
