Owain G. Ainsworth ec8d0e582c Attempt to create less garbage for getaddr calls. 
We make ka.na immutable in the address manager. Whenever we would update
the structure we replace it with a new copy. This beats making a copy of
all addresses once per getaddr command (max is just over 23000 we would
be copying, compared to at most 2000 copies on a new getaddr that has
all addresses we know with newer dates).

btcd

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

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

This project is currently under active development and is in an Alpha state.

It currently properly downloads, validates, and serves the block chain using the exact rules (including bugs) for block acceptance as the reference implementation (bitcoind). 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).

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

One key difference between btcd and bitcoind 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 btcgui projects which are both under active development.

Requirements

Go 1.2 or newer.

Installation

Windows - MSI Available

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

Linux/BSD/POSIX - Build from Source

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

  • Run the following command to obtain btcd, all dependencies, and install it: $ go get github.com/conformal/btcd/...

  • btcd (and utilities) will now be installed in either $GOROOT/bin or $GOPATH/bin depending on your configuration. 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/POSIX - Build from Source

  • Run the following command to update btcd, all dependencies, and install it: $ go get -u -v github.com/conformal/btcd/...

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

Documentation

The documentation is a work-in-progress. It uses the github wiki facility.

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 Conformal. 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
