Bit is a common unit used to designate a sub-unit of a bitcoin - 1,000,000 bits is equal to 1 bitcoin (BTC).


An economic bubble or asset bubble (sometimes also referred to as a speculative bubble, a market bubble, a price bubble, a financial bubble, a speculative mania, or a balloon) is a situation in which asset prices appear to be based on implausible or inconsistent views about the future. It could also be described as trade in an asset at a price or price range that strongly exceeds the asset's intrinsic value.

Bitcoin Network

The bitcoin network is a peer-to-peer payment network that operates on a cryptographic protocol. Users send and receive bitcoins, the units of currency, by broadcasting digitally signed messages to the network using bitcoin cryptocurrency wallet software. Transactions are recorded into a distributed, replicated public database known as the blockchain, with consensus achieved by a proof-of-work system called mining. Satoshi Nakamoto, the designer of bitcoin, claimed that design and coding of bitcoin began in 2007. The project was released in 2009 as open source software.

Bitcoin Core

Bitcoin Core is free and open-source software that serves as a bitcoin node (the set of which form the bitcoin network) and provides a bitcoin wallet which fully verifies payments. It is considered to be bitcoin's reference implementation. Initially, the software was published by Satoshi Nakamoto under the name "Bitcoin", and later renamed to "Bitcoin Core" to distinguish it from the network. It is also known as the Satoshi client.

Byzantine Fault Tolerance

A condition of a computer system, particularly distributed computing systems, where components may fail and there is imperfect information on whether a component has failed. The term takes its name from an allegory, the "Byzantine Generals Problem", developed to describe a situation in which, in order to avoid catastrophic failure of the system, the system's actors must agree on a concerted strategy, but some of these actors are unreliable.

Bull / Bullish

A market condition where investors generally expect upward price movement, and/or an entity who holds a generally positive outlook for a particular stock or asset.

Block Explorer

A Block Explorer is a web application to view and query blocks on the Blockchain. The primary function is to allow anyone with an Internet connection to track bitcoin transactions or interactions, regardless of his or her level of knowledge and expertise.


A bitcoin block is a permanently recorded file containing information on transactions. Each block includes the cryptographic hash of the prior block in the blockchain, linking the two. The linked blocks form a blockchain. If you think of blockchain as a big spreadsheet in the cloud, then each row in the spreadsheet might be a block.

Bear / Bearish

A market condition in which investors expect downward price movement of stocks or assets (like bitcoin or gold), and/or any entity who generally holds negative sentiment about the price of a stock or asset.

Bag / Bagholder

An investor or shareholder left holding shares of worthless stocks or any financial instruments that become worthless, such as the coins of a failed cryptocurrency.
