The network performance is measured based on the worst hardware specification within the network. According to the blockchain network structure, it is only possible to be scaled up vertically (increasing hardware capacity). Hence, it is recommended that all the nodes within the network should have the best hardwares having the similar specifications with each other at least.
The following sections show the recommended specifications for both CNs and PNs.
Note that this is a recommended hardware specification for CNs and PNs, not an exact requirement. Any physical machine with similar hardware configurations would be sufficient to operate a CN or a PN.
This storage specification is derived from AWS EBS SSD (gp3) specification.
This storage specification is derived from Azure Premium Disk specification.

Assuming 100 TPS in average, 300 bytes average transaction size, and 1-second block latency, the expected daily storage requirement is about 2.5 GB/day (=300x100x86400).
Recommended environment is compatible with RHEL (7.8 or later). Klaytn binaries are fully tested on Amazon Linux 2, but they should work on other linux-based environments as well. macOS binaries are also provided for development purpose.
