Simple Summary

This TIP will add a proposal to adjust the total net limit.

Abstract

The total net limit stands for the bandwidth resource distributed to all the users when they freeze their TRX balances. At present, the total net limit TOTAL_NET_LIMIT parameter is set as a fixed value of 43.2 billion according to a rough estimate, which is not flexible enough to adapt to the rapid development of the TRON network. So we propose to change the total net limit parameter.

Motivation

The current fixed TOTAL_NET_LIMIT parameter is estimated by the following equation:

43,200,000,000 = 500 * 1000 * 86400

where 500 stands for the average transaction byte size, 1000 stands for TPS, and 86400 stands for the total number of seconds in a day.

However, the estimated value is not accurate. Instead of being a fixed value, it is better to make the TOTAL_NET_LIMIT parameter configurable.

Specification

The TOTAL_NET_LIMIT proposal type is defined as :

 public enum ProposalType {
  ...
  TOTAL_NET_LIMIT(62); // 43_200_000_000L, [0, 1000_000_000_000L]
  ...
 }

The proposal code is 62 and its initial value is set 43,200,000,000. The valid range of TOTAL_NET_LIMIT parameter is [0, 1000,000,000,000].

Rationale

It is quite necessary to adjust the total net limit to adapt to different situations in the TRON network.
