Josh Rickmar b2263ba6f5 Notify connecting frontends of btcd connect state. 
This change automatically sends the btcdconnected notification for all
frontends as they connect to btcwallet.  The old btcdconnected command
has been removed, as it is no longer needed for clients to explicitly
request this information any longer.

README.md

btcwallet

btcwallet is a daemon handling bitcoin wallet functions. It relies on a running btcd instance for asynchronous blockchain queries and notifications over websockets.

Full btcd installation instructions can be found here.

btcwallet runs as a daemon and provides no user interface for a wallet. A btcwallet frontend, such as btcgui, is required to use btcwallet.

In addition to the HTTP server run by btcd to provide HTTP and websocket RPC, btcwallet requires an HTTP server of its own to provide websocket connections to wallet frontends. Websockets allow for asynchronous queries, replies, and notifications between btcd and btcwallet, as well as between btcwallet and any number of frontends.

This project is currently under active development is not production ready yet. Because of this, support for using the main Bitcoin is currently disabled, and testnet must be used instead.

Installation

Windows - MSI Available

Install the btcd suite MSI here:

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 commands to obtain btcwallet, all dependencies, and install it:

$ go get -u -v github.com/conformal/btcd/...
$ go get -u -v github.com/conformal/btcwallet/...
  • btcd and btcwallet will now be installed in either $GOROOT/bin or $GOPATH/bin depending on your configuration. If you did not already add to your system path during the installation, we recommend you do so now.

Updating

Windows

Install a newer btcd suite MSI here:

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

Linux/BSD/POSIX - Build from Source

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

Getting Started

Windows (Installed from MSI)

Open Btcd Suite from the Btcd Suite menu in the Start Menu. This will also open btcgui, which can be closed if you only want btcd and btcwallet running.

Linux/BSD/POSIX/Source

  • Run the following commands to start btcd and btcwallet:
$ btcd --testnet -u rpcuser -P rpcpass
$ btcwallet -u rpcuser -P rpcpass

Frontend Usage

Frontends wishing to use btcwallet must connect to the websocket /wallet. Messages sent to btcwallet over this websocket are expected to follow the standard Bitcoin JSON API and replies follow the same API. The btcd package btcjson provides types and functions for creating messages that this API. However, due to taking a synchronous protocol like HTTP and using it asynchronously with websockets, it is recommend for frontends to use the JSON id field as a sequence number so replies can be mapped back to the messages they originated from.

TODO

  • Require authentication before wallet functionality can be accessed
  • Serve websocket connections over TLS
  • Rescan the blockchain for missed transactions
  • Documentation (specifically the websocket API additions)
  • Code cleanup
  • Optimize
  • Much much more. Stay tuned.

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
