package future

// A Future represents the result of some asynchronous computation.
// Future returns the result of the work as an error, or nil if the work
// was performed successfully.
// Implementers must observe these invariants
// 1. There may be multiple concurrent callers, or Future may be called many
//     times in sequence, it must always return the same value.
// 2. Future blocks until the work has been performed.

### 1. Overview

When developing bitcoin applications or testing potential changes, it is often extremely useful to have a test network where transactions are actually mined into blocks and difficulty levels are low enough to generate blocks as needed.

In order to facilitate these scenarios, btcd provides a simulation network (--simnet). The following is an overview of the most important properties that distinguish it from the main network:

# Based on the directions here: https://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_Clean_Chroot
# This will take a while to build, with most of the time spent on QT4. There is some redundancy with creating
# multiple clean chroots, but I think this approach is easier and more reliable for most systems.

# Specify a build directory. Defaults to /tmp:
BUILDDIR="/tmp"

# Install devtools if it's not already installed:
