Run zkSync Prover

Components

To run a prover for zkSync-era-based networks, you are required to run an external-node, a circuit-synthesizer and several provers, to be specific:

External-node

• Synchronizing necessary data from L1 and trusted L2 node

• Managing and sending ready proofs to L1 to earn rewards

Circuit-synthesizer

• Distributing and collecting proof tasks

Prover

• Performing ZKP calculation tasks

Requirements

OS: Ubuntu 20.04 amd64 LTS and above

Prover GPU: GeForce 30 Series and above

Prerequisites

The deploying steps mentioned in this documentation require docker and docker-compose to be previously installed. Check the following links if you haven't installed the dependencies yet.

• https://www.docker.com/get-started

• https://docs.docker.com/compose/install/

Remember to set a proper directory for docker root.

Additionally, running a prover requires nvidia-container-toolkit / nvidia-docker2

• https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/1.14.0/install-guide.html#configuring-docker

Install nvidia-container-toolkit & Configuring Docker

    sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \
    sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list \&& \
    sudo apt-get update
    
$ sudo apt-get install -y nvidia-container-toolkit

$ sudo nvidia-ctk runtime configure --runtime=docker

$ sudo systemctl restart docker

Easy Installation

1. External-node

1.1 Install the Base Environment

Automatically check dependencies (including docker, docker-compose, nvidia-container-toolkit) and install missing ones.

wget -c https://pre-alpha-miner-download.opside.network/update/zksync/install-basic-env.sh -O ./install-basic-env.sh && chmod +x ./install-basic-env.sh && ./install-basic-env.sh

1.2 Install the External-node

Automatically downloads docker images and modifies the configuration based on the network selected.

wget -c https://pre-alpha-miner-download.opside.network/update/zksync/run-external-node.sh -O ./run-external-node.sh &&  chmod +x ./run-external-node.sh && ./run-external-node.sh

Enter after the instructions

• Preferred network

  
• Operator address (who submits proofs and receives rewards)

  
• Private key of the operator

• L1 RPC URL

  

2. Prover Group

2.1 Install the Base Environment

See 1.1 #1.1-install-the-base-environment

2.2 Install Prover

Automatically checks the graphic card driver version and downloads the corresponding docker image.

wget -c https://pre-alpha-miner-download.opside.network/update/zksync/run-prover-node.sh -O ./run-prover-node.sh && chmod +x ./run-prover-node.sh && ./run-prover-node.sh

Enter after the instructions

• Preferred network

  
• IP address of the external-node
