Blockchains are tamper evident and tamper resistant digital ledgers implemented in a distributed fashion (i.e., without a central repository) and usually without a central authority (i.e., a bank, company, or government). At their basic level, they enable a community of users to record transactions in a shared ledger within that community, such that under normal operation of the blockchain network no transaction can be changed once published. This document provides a high-level technical overview of blockchain technology. The purpose is to help readers understand how blockchain technology works.
This publication is designed for readers with little or no knowledge of blockchain technology who wish to understand at a high level how it works. It is not intended to be a technical guide; the discussion of the technology provides a conceptual understanding. Note that some examples, figures, and tables are simplified to fit the audience.
