rpctest: Correct several issues in tests and joins.
This corrects several issues with the new rpctest package.

The following is an overview of the issues that have been corrected:

- The JoinNodes code was incorrect for both mempool and blocks.
  - For mempool it was only checking the first node against itself
  - For blocks it was only testing the height instead of hash and height
    which means the chains could be different and it would claim they're
    synced
- The test for mempool joins was inaccurate in a few ways:
  - It was generating separate chains such that the generated
    transaction was invalid (an orphan) on one chain, but not
    the other
  - Mempools are not automatically synced when nodes are connected and
    there is a large random delay before any transaction rebroadcast
    happens, so it can't be relied on for the purposes of this test
- The test for block joins was generating two independent chains of the
  same height with the same difficulty and was only passing due to the
  aforementioned bug in JoinNodes
- All of the ConnectNode calls were connecting the main harness outbound
  to the local test harness instances
  - This is not correct because ConnectNode makes the outbound
    connection persistent, which means once the local test harness is
    gone, it would keep trying to connect for the remainder of the tests
    to a node that is never coming back and instead ends up connecting to
    an independent test harness.

btcd

[Build Status] (https://travis-ci.org/btcsuite/btcd)

btcd is an alternative full node bitcoin implementation written in Go (golang).

This project is currently under active development and is in a Beta state. It is extremely stable and has been in production use since October 2013.

It properly downloads, validates, and serves the block chain using the exact rules (including bugs) for block acceptance as Bitcoin Core. We have taken great care to avoid btcd causing a fork to the block chain. It passes all of the 'official' block acceptance tests (https://github.com/TheBlueMatt/test-scripts) as well as all of the JSON test data in the Bitcoin Core code.

It also relays newly mined blocks, maintains a transaction pool, and relays individual transactions that have not yet made it into a block. It ensures all transactions admitted to the pool follow the rules required by the block chain and also includes the same checks which filter transactions based on miner requirements ("standard" transactions) as Bitcoin Core.

One key difference between btcd and Bitcoin Core is that btcd does NOT include wallet functionality and this was a very intentional design decision. See the blog entry here for more details. This means you can't actually make or receive payments directly with btcd. That functionality is provided by the btcwallet and Paymetheus (Windows-only) projects which are both under active development.

Requirements

Go 1.6 or newer.

Installation

Windows - MSI Available

https://github.com/btcsuite/btcd/releases

Linux/BSD/MacOSX/POSIX - Build from Source

  • Install Go according to the installation instructions here: http://golang.org/doc/install

  • Ensure Go was installed properly and is a supported version:

$ go version
$ go env GOROOT GOPATH

NOTE: The GOROOT and GOPATH above must not be the same path. It is recommended that GOPATH is set to a directory in your home directory such as ~/goprojects to avoid write permission issues. It is also recommended to add $GOPATH/bin to your PATH at this point.

  • Run the following commands to obtain btcd, all dependencies, and install it:
$ go get -u github.com/Masterminds/glide
$ git clone https://github.com/btcsuite/btcd $GOPATH/src/github.com/btcsuite/btcd
$ cd $GOPATH/src/github.com/btcsuite/btcd
$ glide install
$ go install . ./cmd/...
  • btcd (and utilities) will now be installed in $GOPATH/bin. If you did not already add the bin directory to your system path during Go installation, we recommend you do so now.

Updating

Windows

Install a newer MSI

Linux/BSD/MacOSX/POSIX - Build from Source

  • Run the following commands to update btcd, all dependencies, and install it:
$ cd $GOPATH/src/github.com/btcsuite/btcd
$ git pull && glide install
$ go install . ./cmd/...

Getting Started

btcd has several configuration options avilable to tweak how it runs, but all of the basic operations described in the intro section work with zero configuration.

Windows (Installed from MSI)

Launch btcd from your Start menu.

Linux/BSD/POSIX/Source

$ ./btcd

Issue Tracker

The integrated github issue tracker is used for this project.

Documentation

The documentation is a work-in-progress. It is located in the docs folder.

GPG Verification Key

All official release tags are signed by Conformal so users can ensure the code has not been tampered with and is coming from the btcsuite developers. To verify the signature perform the following:

  • Download the public key from the Conformal website at https://opensource.conformal.com/GIT-GPG-KEY-conformal.txt

  • Import the public key into your GPG keyring:

    gpg --import GIT-GPG-KEY-conformal.txt
    
  • Verify the release tag with the following command where TAG_NAME is a placeholder for the specific tag:

    git tag -v TAG_NAME
