This TIP will add a proposal to adjust the free net limit in an account.
The free net limit is the free bandwidth resource that can be used by the users to decrease the transaction fee. At present, the free net limit is set as a fixed value 5000. But recently, some malicious behaviors are discovered to generate lots of fraudulent TRC10 transactions by abusing the free bandwidth resources. To restrain this situation, we propose to change the free net limit.
We can restrain the fraudulent TRC10 transactions by increasing their cost. So the free net limit value should be configurable instead of being a fixed value. The free net value limit needs to be decreased when lots of fake TRC10 transactions appeared. There should be a proposal to change the free net limit.
The FREE_NET_LIMIT proposal type is defined as :
public enum ProposalType {
...
FREE_NET_LIMIT(61), // 5000, [0, 100_000]
...
}The proposal code is 61 and its initial value is set 5000. The valid range of FREE_NET_LIMIT parameter is [0, 100,000].
The average bandwidth consumption of a transaction is in the range [300, 500], so the FREE_NET_LIMIT parameter can be adjusted according to the number of free transactions the users are allowed to use in a day.
In addition, to restrain the fraudulent TRC10 transactions, it is quite necessary to adjust the free net limit to adapt to different situations in the TRON network.
