Whois & Analysis for blockchain.com

Bitcoin is both a cryptocurrency and an electronic payment system invented by an unidentified programmer, or group of programmers, under the name of Satoshi Nakamoto.

Bitcoin was introduced on 31 October 2008 to a cryptography mailing list, and released as open-source software in 2009.

The identity of Nakamoto remains unknown, though many have claimed to know it.

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.".

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.
