Technical Requirements
Node Specifications
These are the recommended specs for a ZetaChain node.
| Node Type | CPU | Memory | Data Disk |
|---|---|---|---|
| Observer Signer | 8 CPUs | 32 GB Memory | 300+ GB Data Disk |
| Core Validator | 4 CPUs | 16 GB Memory | 300+ GB Data Disk |
It is recommended to run a validator on a machine with NVMe SSDs that support high IOPS (12K or higher).
Network Requirements
Public Ports
ZetaChain nodes communicate over the following ports. Make sure these are open to the public internet.
| Node Type | Port | Protocol |
|---|---|---|
| Full Node and Validator | 26656 | TCP |
| Observer Signer Only | 8123 | TCP |
| Observer Signer Only | 6668 | TCP |
Additionally, Observer Signers must allow communication between zetacored and
zetaclientd on port 9090 but this port should not be publicly accessible.
RPC/API/Archive Nodes
If you want to access RPC/API services on your node you'll need to make sure the following ports are open.
| RPC Type | Port | Protocol |
|---|---|---|
| EVM RPC - HTTP | 8545 | TCP |
| EVM RPC - WSS | 8546 | TCP |
| Cosmos RPC | 1317 | TCP |
Operating System
ZetaChain nodes have been developed and tested on x86_64 architecture. Our binary files have been compiled with Ubuntu 22.04 LTS x86_64. This guide assumes you are using Ubuntu 22.04 LTS x86_64. If you are using a different OS you may need to make some adjustments.
