[
ppcwallet is a daemon handling bitcoin wallet functionality for a single user. It acts as both an RPC client to ppcd and an RPC server for wallet clients and legacy RPC applications. It is based on the Conformal btcwallet code.
Public and private keys are derived using the heirarchical
deterministic format described by
BIP0032.
Unencrypted private keys are not supported and are never written to
disk. btcwallet uses the
m/44'/<coin type>'/<account>'/<branch>/<address index>
HD path for all derived addresses, as described by
BIP0044.
Due to the sensitive nature of public data in a BIP0032 wallet, btcwallet provides the option of encrypting not just private keys, but public data as well. This is intended to thwart privacy risks where a wallet file is compromised without exposing all current and future addresses (public keys) managed by the wallet. While access to this information would not allow an attacker to spend or steal coins, it does mean they could track all transactions involving your addresses and therefore know your exact balance. In a future release, public data encryption will extend to transactions as well.
ppcwallet is not an SPV client and requires connecting to a local or remote ppcd instance for asynchronous blockchain queries and notifications over websockets. Full ppcd installation instructions can be found here. An alternative SPV mode that is compatible with ppcd and Peercoin Core is planned for a future release.
No release-ready graphical frontends currently exist, however the proof-of-concept btcgui project shows some of the possibilities of btcwallet. In the coming months a new stable RPC API is planned, at which point a high quality graphical frontend can be finished.
Mainnet support is currently disabled by default. Use of btcwallet on
mainnet requires passing the --mainnet flag on the command line or
adding mainnet=1 to the configuration file. Mainnet will be enabled
by default in a future release after further database changes and
testing.
-
Install Go according to the installation instructions here: http://golang.org/doc/install
-
Run the following commands to obtain and install ppcwallet and all dependencies:
$ go get -u -v github.com/ppcsuite/ppcd/...
$ go get -u -v github.com/ppcsuite/ppcwallet/...- ppcd and ppcwallet will now be installed in either
$GOROOT/binor$GOPATH/bindepending on your configuration. If you did not already add to your system path during the installation, we recommend you do so now.
- Run the following commands to update ppcwallet, all dependencies, and install it:
$ go get -u -v github.com/ppcsuite/ppcd/...
$ go get -u -v github.com/ppcsuite/ppcwallet/...The follow instructions detail how to get started with ppcwallet connecting to a localhost ppcd.
- Run the following command to start ppcd:
$ ppcd --testnet -u rpcuser -P rpcpass- Run the following command to start ppcwallet:
$ ppcwallet -u rpcuser -P rpcpassIf everything appears to be working, it is recommended at this point to copy the sample ppcd and ppcwallet configurations and update with your RPC username and password.
$ cp $GOPATH/src/github.com/ppcsuite/ppcd/sample-btcd.conf ~/.ppcd/ppcd.conf
$ cp $GOPATH/src/github.com/ppcsuite/ppcwallet/sample-btcwallet.conf ~/.ppcwallet/ppcwallet.conf
$ $EDITOR ~/.ppcd/ppcd.conf
$ $EDITOR ~/.ppcwallet/ppcwallet.confClients wishing to use ppcwallet must connect to the ws endpoint
over a websocket connection. Messages sent to ppcwallet over this
websocket are expected to follow the standard Bitcoin JSON API
(partially documented
here).
Websocket connections also enable additional API extensions and
JSON-RPC notifications (currently undocumented). The ppcd packages
btcjson and btcws provide types and functions for creating and
JSON (un)marshaling these requests and notifications.
