Deploy CPU Prover

1. Prepare the host:

   • Instance: AWS r7i.16xlarge (64 vCPUs) or equivalent.
   • OS: ubuntu-24.04-amd64-server.
   • Install prerequisites:
     • Rust (restart the shell after installation).
     • Build tools: sudo apt-get update && sudo apt-get install -y build-essential cmake git pkg-config libssl-dev protobuf-compiler
     • sqlx-cli: cargo install sqlx-cli

2. Install Docker and add your user to the docker group:

   sudo groupadd docker 2>/dev/null || true && sudo usermod -aG docker $USER
   

3. Download the CPU image from /home/ubuntu:

   curl -sL -O https://pico-proofs.s3.us-west-2.amazonaws.com/prover-network/mainnet/pico-proving-service-cpu.tar
   

4. Load the image:

   # If old image exists, delete it firstly
   docker rmi -f pico-proving-service-cpu:latest
   
   # Load the new downloaded image   
   docker load -i pico-proving-service-cpu.tar
   

5. Clone the repository and enter the CPU Docker folder:

   git clone https://github.com/brevis-network/pico-proving-service
   cd pico-proving-service/docker/cpu
   

6. Copy the environment template:

   cp .env.example .env
   

   Keep the default values unless you have a specific reason to override them.

7. Download dependencies and start the containers:

   # delete the old gnark files for upgrade if exist
   rm -rf ../gnark_downloads
      
   make download-gnark
   make up
   

8. Check container status:

   docker ps
   

   You should see pico-proving-service and pico_gnark_server. The Gnark server produces the final on-chain verifiable proof.

9. Review the Makefile for lifecycle targets (stop/restart/clean). For logs, run:

   make logs-server
   make logs-gnark
