I found an interesting article about the Cartesi staking program at stakingrewards.com
the reward given is quite large, if we enter 1000 CTSI for staking for 1 month, then we will get 142 CTSI or a range of 14% per month. for detailed information you can visit this link

If you're talking about Staking Rewards page it is working fine for me, maybe you have an internet connection issue, try vpn or another browser/device or maybe they were updating the page and it was unavailable before and it is available now. Also you can check out mining page for staking details:
