If you need to develop on Linux or macOS, just install the .NET Core SDK.

For more information about how to build dApps for Phantasma, please read the documentation.

Debuging

To effectively debug Phantasma.Node, follow the steps outlined below:

1. Tendermint Executable:

   • To debug Phantasma.Node, it's essential to have the tendermint executable.
   • Download it from this URL: Tendermint v0.34.21 Release.
   • Place the downloaded executable inside the path: /path/to/phantasma-ng/Phantasma.Node/src/bin/Debug/net6.0/tendermintFile.

2. Configuration Settings:

   • In the config.json file, ensure that you specify the path to the folder mentioned above and the tendermint executable.
   • You can find an example configuration in the Phantasma.Node/src directory.

3. Reset the Blockchain:

   • Delete the Storage folder.
   • Remove the Storage folder located at /path/to/phantasma-ng/Phantasma.Node/src/bin/Debug/net6.0/.
   • Remove the data folder found inside /path/to/phantasma-ng/Phantasma.Node/src/bin/Debug/net6.0/tendermintFile.
   • Navigate to the DOCKER folder using a terminal and execute the script: ./fix-storage.sh. This will reset the blockchain.
   • An easy way to do the deployment and reset in on step is to run this command: cd DOCKER && ./fix-storage.sh || cd .. && ./testnet-startup.sh.

4. Edit Necessary Files for Protocol Version:

   • In Phantasma.Business/src/Blockchain/Nexus/Nexus.cs:
     • Update the value of DomainSettings.Phantasma30Protocol to DomainSettings.LatestKnownProtocol at lines 937, 961, and 978.
   • In Phantasma.Node/src/ABCIConnector.cs:
     • Update the value on line 420 from uint version = DomainSettings.Phantasma30Protocol; to uint version = DomainSettings.LatestKnownProtocol;.

5. Run Node in Editor:

   • If you intend to run the node in an editor like Rider or Visual Studio for debugging purposes:
     • Edit the DOCKER/wrapper-testnet.sh file.
     • Comment out line 28.
