About ZKS:

“EOS Mainnet users struggle having enough CPU/Net resources when developing, playing games and using dapps.

ZKS offers an easily redeemable solution. The ZKS tokens are redeemed for CPU and Network resources on the EOS Mainnet through a smart-contract. We have simplified the process of allocating CPU and Network.
 ZKS tokens have been designed to be a very simple utility token, that provides 0.9 CPU and 0.1 NET for 3 Hours
 for each ZKU redeemed. There are no complex mechanisms for issuance or redemption.”
