Bitcoin Private
----------------

**Bitcoin Private v1.0.10-1**

P2P Port: 7933  
RPC Port: 7932

Bitcoin Private is a fork of Zclassic, merging in the UTXO set of Bitcoin. BTCP is financial freedom.

### Info

The snapshot will take place on February 28th. The fork (creation of BTCP) will occur shortly after, on March 2nd.

Install
-----------------
### Linux

Get dependencies:
```{r, engine='bash'}
sudo apt-get install \
      build-essential pkg-config libc6-dev m4 g++-multilib \
      autoconf libtool ncurses-dev unzip git python \
      zlib1g-dev wget bsdmainutils automake
```

Install:
```{r, engine='bash'}
# Build
./btcputil/build.sh -j$(nproc)
# Fetch Zcash ceremony keys
./btcputil/fetch-params.sh
# Run
./src/btcpd
```

### Windows
There are two proven ways to build BTCP for Windows:

* On Linux using [Mingw-w64](https://mingw-w64.org/doku.php) cross compiler tool chain. Ubuntu 16.04 Xenial is proven to work and the instructions is for such release.
* On Windows 10 (64-bit version) using [Windows Subsystem for Linux (WSL)](https://msdn.microsoft.com/commandline/wsl/about) and Mingw-w64 cross compiler tool chain.

With Windows 10, Microsoft released a feature called WSL. It basically allows you to run a bash shell directly on Windows in an ubuntu environment. WSL can be installed with other Linux variants, but as mentioned before, the distro proven to work is Ubuntu.
Follow this [link](https://msdn.microsoft.com/en-us/commandline/wsl/install_guide) for installing WSL first

### Building for Windows 64-Bit
1. Get the usual dependencies:
```{r, engine='bash'}
sudo apt-get install \
      build-essential pkg-config libc6-dev m4 g++-multilib \
      autoconf libtool ncurses-dev unzip git python \
      zlib1g-dev wget bsdmainutils automake mingw-w64
```

2. Set the default ming32 gcc/g++ compiler option to posix

```{r, engine='bash'}
sudo apt install mingw-w64
sudo update-alternatives --config x86_64-w64-mingw32-gcc
sudo update-alternatives --config x86_64-w64-mingw32-g++
```

3. Install Rust
```{r, engine='bash'}
curl https://sh.rustup.rs -sSf | sh
source ~/.cargo/env
rustup install stable-x86_64-unknown-linux-gnu
rustup install stable-x86_64-pc-windows-gnu
rustup target add x86_64-pc-windows-gnu
vi  ~/.cargo/config
```
and add:
```
[target.x86_64-pc-windows-gnu]
linker = "/usr/bin/x86_64-w64-mingw32-gcc"
```

Note that in WSL, the BTCPrivate source code must be somewhere in the default mount file system. i.e /usr/src/BTCPrivate, and not on /mnt/d/. What this means is that you cannot build directly on the windows system

4. Build for Windows

```{r, engine='bash'}
PATH=$(echo "$PATH" | sed -e 's/:\/mnt.*//g') # strip out problematic Windows %PATH% imported var
./btcputil/build-win.sh -j$(nproc)
```

5. Installation

After building in WSL, you can make a copy of the compiled executables to a directory on your Windows file system. This is done the following way

```{r, engine='bash'}
make install DESTDIR=/mnt/c/btcp/BTCPrivate
```
This will install the executables to `c:\btcp\BTCPrivate

### Mac
Get dependencies:
```{r, engine='bash'}
#install xcode
xcode-select --install

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install cmake autoconf libtool automake coreutils pkgconfig gmp wget

brew install gcc5 --without-multilib
```

Install:
```{r, engine='bash'}
# Build
./btcputil/build-mac.sh -j$(sysctl -n hw.physicalcpu)
# fetch key
./btcputil/fetch-params.sh
# Run
./src/btcpd
```

About
--------------

[Bitcoin Private](http://zclassic.org/), like [Zclassic](https://zclassic.org/) and [Zcash](https://z.cash/), is an implementation of the "Zerocash" protocol.
Based on Zclassic's code, it intends to offer a far higher standard of privacy
through a sophisticated zero-knowledge proving scheme that preserves
confidentiality of transaction metadata. Technical details are available
in the Zcash [Protocol Specification](https://github.com/zcash/zips/raw/master/protocol/protocol.pdf).

This software is the Bitcoin Private client. It downloads and stores the entire history
of Bitcoin Private transactions. Depending on the speed of your computer and network
connection, the synchronization process could take a day or more once the
blockchain has reached a significant size.

It includes both `btcpd` (the daemon) and `btcp-cli` (the command line tools).

Security Warnings
-----------------

See important security warnings in
[doc/security-warnings.md](doc/security-warnings.md).

**Bitcoin Private is unfinished and highly experimental.** Use at your own risk.

Deprecation Policy
------------------

This release is considered deprecated 16 weeks after the release day. There
is an automatic deprecation shutdown feature which will halt the node some
time after this 16 week time period. The automatic feature is based on block
height and can be explicitly disabled.
