Run a VFlow RPC Node

VFlow is the EVM parachain of zkVerify. A VFlow node also runs an embedded zkVerify relay-chain node, so it syncs and stores both chains.

Network Details

Network	EVM chain ID	Para ID	Relay chain	Public RPC
Mainnet	1408	1	zkVerify mainnet	wss://vflow-rpc.zkverify.io
Testnet	1409	1	zkVerify Volta testnet	wss://vflow-volta-rpc.zkverify.io

Hardware Requirements

A VFlow node includes a zkVerify node, so use at least the RPC node requirements listed in Getting Started.

For an archive node, plan for at least 1000 GB of fast NVMe storage.

Run with Docker

The compose-vflow-simplified repository works the same way as compose-zkverify-simplified, so the prerequisites are the same. Each script asks for the node type and the network.

1. Check the releases page for the latest tag and clone it:

   git clone --branch latest_tag https://github.com/zkVerify/compose-vflow-simplified.git
   cd compose-vflow-simplified

2. Run the initialization script:

   scripts/init.sh

   It asks for the node type (select rpc-node), the network (mainnet or testnet), whether to run an archive node and a few optional settings, then writes the deployment files under deployments/rpc-node/network.

3. Start the node:

   scripts/start.sh

   Stop it with scripts/stop.sh. To update to a new release, check out the latest tag and run scripts/update.sh.

By default the node serves Substrate and Ethereum JSON-RPC on port 9944 and uses port 30555 for P2P.

Snapshots

Daily snapshots are available for mainnet and testnet. A VFlow node needs both the VFlow snapshot and the zkVerify relay-chain snapshot. The steps are in the repository README.
