Blockchain Technology Overview下载

Blockchains are immutable digital ledger systems implemented in a distributed fashion (i.e., 84 without a central repository) and usually without a central authority. At its most basic level, they 85 enable a community of users to record transactions in a ledger public to that community such that 86 no transaction can be changed once published. This document provides a high-level technical 87 overview of blockchain technology. It discusses its application to electronic currency in depth, 88 but also shows its broader applications. The purpose is to help readers understand how 89 blockchains work, so that they can be appropriately and usefully applied to technology problems. 90 Additionally, this document explores some specific blockchain applications and some examples 91 of when a blockchain system should be considered for use.
