🖥️Installation

Set up a verifier to run in the background, ensuring that data shares remain intact and helping maintain the network’s integrity

Go to the faucet to obtain NIL in your Keplr wallet

Update System

sudo apt update && sudo apt upgrade -y

Install Prerequisites & Docker

sudo apt install apt-transport-https ca-certificates curl software-properties-common -y && curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - && sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable" && sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin -y

Verify Docker Installation

docker --version

You should see output like Docker version 27.1.2, build d01f264

Download accuser Image

docker pull nillion/retailtoken-accuser:v1.0.0

Create accuser directory

mkdir -p nillion/accuser

Run the container to initialise accuser & register

docker run -v ./nillion/accuser:/var/tmp nillion/retailtoken-accuser:v1.0.0 initialise

This will output the details needed to register the accuser on the website, connect your keplr wallet & register them below:

  • accound_id: Nillion address of the accuser

  • public_key: Public Key of the accuser

The accuser will save the credentials in a file named credentials.json within the created folder. It's important to back up this file if you lose it, you'll lose access to the keys and address of the accuser.

Funding the accuser

To file accusations on Nilchain, you must first fund the accuser account with NIL. You can obtain this from the Nillion faucet

The Nillion address of the accuser is the one that was generated and entered in the previous step (not your Keplr wallet address).

Running the accuser

YOU MUST WAIT 30-60 MINUTES TO CONTINUE WITH THE STEPS BELOW

docker run -d -v ./nillion/accuser:/var/tmp nillion/retailtoken-accuser:v1.0.0 accuse --rpc-endpoint "https://testnet-nillion-rpc.lavenderfive.com/" --block-start 5096617

Adjust the --block-start value to the block height just before your registered verifier. To find this height, check the address you used to register your verifier on your connected Keplr wallet, then look up the transaction hash of type "Pay For" on the blockchain explorer to determine the block height where your verifier was registered

Check verifier logs

# List Available Docker Container
docker ps

# Display logs
docker logs -f <container-id>

Wait until it synchronizes with the current block height. Once it does, you should see if the status shows "Registered" as true.
