       A Note from the Authors

      Throughout this book you will see a distinction between “bitcoin” written with a lowercase “b” and “Bitcoin” with an uppercase “B.” The former refers to bitcoin’s status as a currency, the latter is a reference to the overarching system and protocol that underpins that currency and other uses for the Bitcoin blockchain ledger.

      Addressing an inconsistency in popular parlance, we generally employ three distinct usages of the word “blockchain”: “The blockchain,” which refers to Bitcoin’s original distributed ledger; “a blockchain”— or, pluralized, “blockchains”— to cover a variety of more recent distributed ledgers that share Bitcoin’s chain-of-blocks structure; and “blockchain technology,” referring to the overall field. We also use “distributed ledger technology” to encompass both blockchain and non-blockchain distributed ledgers. We mostly avoid the popular construct of “blockchain” as a non-countable noun. We view a blockchain, like any ledger, as a distinct, identifiable thing, not a process. The book’s title uses the definite article form to acknowledge the catalytic role that the original Bitcoin blockchain played in unleashing this field.
