Bitcoin. This article contains special characters. Without proper rendering support, you may see question marks, boxes, or other symbols. Bitcoin (abbreviation: BTC; sign: ₿) is the first decentralized cryptocurrency.
A cryptocurrency, crypto-currency, or crypto [a] is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it. [2]
The number π (/paɪ/; spelled out as "pi") is a mathematical constant that is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159. The number π appears in many formulae across mathematics and physics. It is an irrational number, meaning that it cannot be expressed exactly as a ratio of two integers, although ...

In the explanations below, any indication of a bit's position is counted from the right (least significant) side, advancing left. For example, the binary value 0001 (decimal 1) has zeroes at every position but the first (i.e., the rightmost) one.
The bit shifts are sometimes considered bitwise operations, because they treat a value as a series of bits rather than as a numerical quantity. In these operations, the digits are moved, or shifted, to the left or right. Registersin a computer processor have a fixed width, so some bits will be "shifted out" of the register at one end, while the sam...
Bitwise operations are necessary particularly in lower-level programming such as device drivers, low-level graphics, communications protocol packet assembly, and decoding. Although machines often have efficient built-in instructions for performing arithmetic and logical operations, all these operations can be performed by combining the bitwise oper...
Sometimes it is useful to simplify complex expressions made up of bitwise operations, for example when writing compilers. The goal of a compiler is to translate a high level programming language into the most efficient machine codepossible. Boolean algebra is used to simplify complex bitwise expressions.
"Bitwise Operations Mod N" by Enrique Zeleny, Wolfram Demonstrations Project.the free encyclopedia that anyone can edit. 550 Madison Avenue is a postmodern skyscraper on Madison Avenue between 55th Street and 56th Street in New York City. Designed by Philip Johnson and John Burgee with associate architect Simmons Architects, the building was completed in 1984. It is a 647-foot-tall (197-meter), 37-story office tower ...
A blockchain is a distributed ledger with growing lists of records ( blocks) that are securely linked together via cryptographic hashes. [1] [2] [3] [4] Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves).
Tibet ( / tɪˈbɛt / ⓘ; Tibetan: བོད, Lhasa dialect: [pʰøːʔ˨˧˩] Böd; Chinese : 西藏; pinyin : Xīzàng ), or Greater Tibet, is a region in the central part of East Asia, covering much of the Tibetan Plateau and spanning about 2,500,000 km 2 (970,000 sq mi). It is the homeland of the Tibetan people.
