Dave Collins a7b35d9f9e chaincfg/blockchain: Parameterize more chain consts. (#732)
This moves several of the chain constants to the Params struct in the
chaincfg package which is intended for that purpose.  This is mostly a
backport of the same modifications made in Decred along with a few
additional things cleaned up.

The following is an overview of the changes:

- Comment all fields in the Params struct definition
- Add locals to BlockChain instance for the calculated values based on
  the provided chain params
- Rename the following param fields:
  - SubsidyHalvingInterval -> SubsidyReductionInterval
  - ResetMinDifficulty -> ReduceMinDifficulty
- Add new Param fields:
  - CoinbaseMaturity
  - TargetTimePerBlock
  - TargetTimespan
  - BlocksPerRetarget
  - RetargetAdjustmentFactor
  - MinDiffReductionTime

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 1.5 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.

NOTE: If you are using Go 1.5, you must manually enable the vendor experiment by setting the GO15VENDOREXPERIMENT environment variable to 1. This step is not required for Go 1.6.

  • 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
