Setting up the Decoder - Configure Enjin’s Blockchain Decoder

The native platform decoder is a robust and fast tool for decoding blockchain transactions and is recommended to be run with the platform. This doesn't have to be hosted on the same Droplet as the platform, but would be recommended for performance. To get started we need to ensure the dart compiler is installed and ready to build the tool by running these commands:

sudo apt-get update

sudo apt-get install apt-transport-https

wget -qO- https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo gpg --dearmor -o /usr/share/keyrings/dart.gpg

echo 'deb [signed-by=/usr/share/keyrings/dart.gpg arch=amd64] https://storage.googleapis.com/download.dartlang.org/linux/debian stable main' | sudo tee /etc/apt/sources.list.d/dart_stable.list

sudo apt-get update

sudo apt-get install dart

export PATH="$PATH:/usr/lib/dart/bin"

echo 'export PATH="$PATH:/usr/lib/dart/bin"' >> ~/.profile

Next create a folder for the Platform Decoder repository, it's recommended to create this outside of the Laravel root folder:

cd ~

mkdir enjin

cd enjin

git clone https://github.com/enjin/platform-decoder.git

Finally build the app:

cd platform-decoder

dart pub get

dart compile exe bin/server.dart -o bin/server

Once built, we'll run the server in the next step along with the other workers.

Updating the Decoder

If you're using Supervisor to keep the decoder running (Keeping the Platform Running) , stop it using:

sudo supervisorctl stop platform-decoder:*

cd ~/enjin/platform-decoder/

Pull the latest version from git and build:

git pull
dart pub get
dart compile exe bin/server.dart -o bin/server

Start the wallet using supervisor:

sudo supervisorctl start platform-decoder:*
