Technical Requirements
Node Specifications
These are the recommended specs for a ZetaChain node.
| Node Type | CPU | Memory | Data Disk |
|---|---|---|---|
| Core Validator | 4 CPUs | 16 GB Memory | 300+ GB Data Disk |
| Fullnode | 4 CPUs | 12 GB Memory | 300+ GB Data Disk |
| Archive | 4 CPUs | 12 GB Memory | 3+ TB Data Disk |
It is recommended to run validators on a machine with NVMe SSDs that support high IOPS (12K or higher) to avoid falling behind and getting the validator jailed.
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 |
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 |
|---|---|---|
| Tendermint | 26657 | TCP |
| 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.
