There will be nothing on the single sided staking within the first 2-4 weeks of Mainnet. The proposal is to have the INC token as a placeholder reward earner for the first 30 / 60 / 90 days of Mainnet. If we have nothing in place, the ability to earn will not be there and will make the ecosystem incomplete. It will take some time for the DAO to review projects that want to be a part of the rewards system in order to be sure they are worthy of our ecosystem. After we review the projects, they will go up for a vote where they could be accepted or denied. The vote timefram after reviewing the project could take up to 2 weeks. So from start to finish it could be 1 month for review and DAO vote to be approved.
Once we have some reward tokens in place, we can then vote to keep or remove the INC token as a reward.
