Kaia’s Network ID will be the same as Klaytn’s.
If you are planning to run a Kaia EN, the hardware requirements are the same as Klaytn’s, which you can find here.
Yes, Kaia will support batching of multiple RPC requests. The default batch limit is 3,000 but this is configurable.
Most RPCs will be the same on Kaia, except for namespace changes (i.e., klay_ to kaia_, although klay_ will remain for backwards compatibility). You will not need to abandon your current setup, and will only need to upgrade the binary to Kaia’s once it is released.
The KAIA market will open in Q3 2024, we will share the exact block number closer to the date.
