Cross platform Bitcoin wallet implementation in .NET Core for a CodeProject tutorial: Build a Bitcoin wallet in C#
The wallet might also will turn out to be the first iteration of a dedicated wallet for a Bitcoin privacy improvement technique, called TumbleBit. TumbleBit will be integrated through NTumbleBit, however in a new repository with new name. This repository will stay as is for the shake of a the CodeProject tutorial.
For further directions of its development see: HiddenWallet. This is its new, rebranded name.
The wallet can communicate with the network through HTTP API and paved the way for a full node integration.
It has a Command Line Interface.
##How to use it
The app is cross-platform, you can try it in any OS. You only need to get dotnet core.
After you acquired dotnet core build the software:
git clone https://github.com/nopara73/DotNetWallet/
cd DotNetWallet/src/DotNetWallet/
dotnet restore
dotnet build
Run the app once, it will generate your configuration file, called Config.json, then open it:
dotnet run
gedit Config.json
Default config looks like this:
{
"DefaultWalletFileName": "Wallet.json",
"Network": "Main",
"ConnectionType": "Http",
"CanSpendUnconfirmed": "False"
}
"Network" can be "Main" or "TestNet". Change to testnet for the shake of practice.
"ConnectionType" can be "Http" or "FullNode". Full node mode is not implemented.
"CanSpendUnconfirmed" can be "False" or "True". Change to "True", so you can play around with it without waiting for confirmations.
