When a new account (wallet) is created with the createencryptedwallet JSON method, all frontends, including the one requesting the wallet, must be notified of this new account and its balance (probably zero). This removes the need for frontends to poll and check for any new accounts. |

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.
