  • Bit

  • Bitcoin

    The first blockchain-based cryptocurrency. Bitcoin was launched in 2009 and remains the most influential and widely recognized decentralized coin. All other cryptocurrencies are referred to as "altcoins."

  • BitLicense

  • Block Explorer

    A web tool available for most cryptocurrencies that allows users to search an address or ID to view its transaction history.

  • Block Height

    The total number of blocks confirmed in a blockchain's history. The measurement is used to compare copies of a blockchain to determine if a given version is up to date.

  • Block Reward

    The payment given to a miner or staker for securing a blockchain that uses a given consensus mechanism.

  • Block Size

    The amount of information that can be stored in one block of a blockchain. The Block Size limit of Bitcoin is 1MB. Blockchains with a larger block size allow for more transactions per block and can confirm more transactions at a time.

  • Blockchain

    A digital record of transactions that is distributed, immutable, and transparent. Records containing the details of individual transactions are grouped into blocks, and these blocks are then linked together in ledger, referred to as the chain. Blockchains are used for recording transactions made with cryptocurrencies, such as Bitcoin, and have many other applications. Transactions are verified with a consensus protocol, such as Proof of Work.

  • Blockchain Bloat

The term gets its name from an allegory called the "Byzantine Generals Problem," where different generals must agree on a concerted strategy, but some of these generals are unreliable. In blockchain, a system is Byzantine Fault Tolerant, if it can reach consensus even when some of the network's nodes are dishonest.
