Bid-Ask Spread. A bid-ask spread is the difference between the bid buy and ask sell price of a particular asset on an exchange. The bid price can be though of as representing demand, while the ask price represents supply. A large bid-ask spread is a sign of poor liquidity in a market. BIP Bitcoin Improvement Proposal 32 BIP 32 established the standard for hierarchical-deterministic HD wallets, a technical improvement over earlier wallets that on random key pairs. BIP 32 allowed for the creation of a hierarchical tree-like wallet structure with more advanced cryptographic security mechanisms.
BIP 38 Password. A Bitcoin Improvement Proposal 38 BIP 38 password enables walletholders to encrypt Bitcoin private keys to offer an extra layer of protection. An encrypted private key requires that a user hold both the private key and the password in order to access wallet funds. This makes private key management a critically important step, which is commonly done on paper wallets and other analog devices for security purposes. Bitcoin Improvement Proposal 39 BIP 39 allows for the generation of a human-readable word recovery phrase for hierarchical-deterministic HD wallets.
With the recovery phrase, users can regenerate an HD wallet that has become lost or damaged. Because they hold such access, BIPenabled recovery phrases should be kept secret and stored securely. BIP 44 allowed two or more separate accounts on the same wallet to hold the same cryptocurrencies in different amounts. The separate accounts could be used for different purposes and coexist in a way similar to checking, business, and savings accounts at legacy banks.
Bitcoin is a blockchain network with a native cryptocurrency bitcoin. It is the first blockchain and cryptocurrency, hence its dominant presence within the broader crypto ecosystem. Bitcoin was established in and pioneered Proof of Work, a technology for reaching consensus on a decentralized network. Bitcoin BTC is a cryptocurrency that can be directly transmitted between users on the Bitcoin network.
It is spelled with a lowercase B, as compared to the Bitcoin network, which is denoted with an upper case B. Bitcoin Cash BCH. Bitcoin Cash is a hard fork of the Bitcoin Network that serves as an electronic cash payment system. Bitcoin Cash's increased block size encourages use as a payment system rather than as a store of value.
A Bitcoiner is holder of bitcoin and an active proponent of the Bitcoin network. Bitcoiners typically believe that bitcoin is the most important and significant digital asset available. Bitcoin Genesis Block. The Bitcoin genesis block was the first block mined on the Bitcoin blockchain. It was mined on January 3, A BIP can be submitted by anyone to be evaluated and reviewed. Bitcoin Network.

The Bitcoin network is a peer-to-peer, decentralized network that allows users to send units of value to each other without any intermediary or bank. Bitcointalk is an internet message forum that was launched by pseudonymous Bitcoin creator Satoshi Nakamoto in to host discussions about Bitcoin, blockchain, and cryptocurrency. It became the meetingpoint for the embryonic blockchain industry, and was the site of the first bitcoin purchase: 10, BTC in exchange for two pizzas. The BitLicense is a business license for virtual currency activity that crypto enterprises must obtain before operating in the state of New York.
Only 25 have been granted as of , while recipients include Circle, Coinbase, Robinhood, and Square. On a blockchain, a block is the data record of all transaction information made during a specific timeframe on its network. Blocks are added sequentially to a network's chain of data, which in turn make up the public ledger known as blockchain. For example: A Bitcoin block contains information about the date, time, and amount of transactions, as well as signature information regarding the origin and destination of the transfer. Blocks must be confirmed by the network via a process of consensus before a chain can continue transacting and creating new blocks.
A blockchain is a public ledger of transactions that is maintained and verified by a decentralized, peer-to-peer network of computers that adhere to a consensus mechanism to confirm data. Each computer in a blockchain network maintains its own copy of the shared record, making it nearly impossible for a single computer to alter any past transactions or for malicious actors to overwhelm the network. Sufficiently decentralized blockchains do not rely on centralized authorities or intermediaries to transact globally, securely, verifiably, and quickly, making technology like cryptocurrency possible.
It allows independent blockchain networks to connect and exchange data. Blockchain Trilemma.
Exchanges Gone Forever 2021
The blockchain trilemma refers to the challenge in achieving a balance between scalability, decentralization, and security in a blockchain network. While scalability refers to the speed and volume of transactions, decentralization refers to the distribution of network nodes, and security refers to the integrity of the system from compromise. The blockchain trilemma states that an equal prioritization of all three factors at once is impossible — so a trade-off must be made with one.
It remains an ambition of blockchain technologists and entrepreneurs to solve for the trilemma with greater effectiveness in the design of any network, update, or application. Block Difficulty. Block difficulty refers to the complexity of computation required to mine new blocks in a Proof-of-Work PoW blockchain environment. Block difficulty is a configurable aspect of a blockchain protocol, and can be used as a mechanism to stabilize block production times in accomodating challenges like transaction speeds and network capacity.
Block Explorer. A block explorer is a software interface that enables users to access realtime blockchain information like transactions, blocks, addresses, nodes, and balances on a particuar network. Operating as web browsers for blockchains, the many free-to-use and open source block explorers are essential in providing for global transparency and democratized access to blockchain network. Block Producers. On most Proof-of-Stake blockchains, block producers are the individuals or group whose hardware is chosen to validate a block's transactions and initiate the next block.
The term originated within blockchain ecosystems that utilize Delegated Proof of Stake DPoS , where users elect block producers to validate and add blocks. Other names for block producers are 'delegates' or 'witnesses. Block Reward. A block reward is the payment awarded to a blockchain network miner upon successfully validating a new block. Typically paid out in the native asset of its network at a fixed, but regressive rate, block rewards are often the only source of new currency creation on a network.
They provide a key element of the incentive structure that keeps blockchain networks operating in a decentralized fashion. In Proof-of-Work blockchains like Bitcoin, block validation and block rewards are the remit of miners. Block Size. Blockchain network protocols are made up of blocks of data that are processed in a perpetually updating chain-like structure — hence the term "blockchain. Block Trade.
A block trade is a large purchase or sale of securities executed outside of an open marketplace. Because the size of the transactions are quite large, block trading is typically done by institutions and hedge funds. The private nature of block trading makes them similar to over-the-counter OTC trading. BNB is the native cryptocurrency of the Binance ecosystem and a Top 10 cryptocurrency by market capitalization.

On the Binance exchange, users can pay for exchange fees like transactions, withdrawals, and listings in BNB and receive a discounted rate. In September , Binance launched the Binance blockchain, upon which BNB can be staked to verify transactions and recieve block rewards. Bollinger Bands. Bollinger Bands are a technical analysis device created by trader John Bollinger in that have become one of the most popular tools used by traders today. Bollinger Bands use moving averages and standard deviation to create a range of price movements. On a trading chart, Bollinger Bands are visually represented by a centerline based on a moving average, with a band below and above the centerline based on standard deviation.
Bollinger Bands can help indicate if prices have moved outside of the range of historical deviation, and can be used to identify a number of market scenarios in real time. A botnet is a collection of internet-connected devices that have been infected by malware, enabling malicious actors to control the devices. Infected devices are oftentimes controlled remotely and without the legitimate device owner's knowledge.
Botnets are often composed of a variety of device types and used by cybercriminals to carry out a broad range of orchestrated online attacks such as credentials leaks, data theft, and DDoS attacks. Brain Wallet.
A brain wallet refers to a crypto private key or seed phrase that has been memorized by its owner. Brain wallets are not recommended as a secure crypto wallet option.
