No real changes needed. Just perhaps a volume trading incentive that promotes the increased usage of zilliqa. The more persons who trade and use increases its value. Thus some incentive for non stakers to invest, perhaps soft staking 1 percent could be useful
A soft staking incentive bonus for casual traders to increase the volume of trade and provide incentive usage of zilliqa. A small amount one percent could increase usage and thereby increase overall zilliqa value.
The current protocol works fine. No changes really needed.
Specifics on implementation unnecessary unless the idea worth pursuing.
