TRON Developer Guide — Super Representatives


This article describes the Super Representative application process, the purpose of the role, and how they play a vital part in TRON’s Delegated Proof of Stake (DPOS) consensus mechanism.


TRON Power (TP) is needed to vote and the amount of TP depends on the voter’s frozen assets(TRX).

TP is calculated in the following way: 1 TP for 1 frozen TRX.

Every account in the TRON network has the right to vote for your own SRs.

After the release(unfreeze), you don’t have any frozen assets and lose all TP accordingly. As a result, all votes become invalid for the ongoing and future voting round unless to freeze again to vote.

Note that the TRON network only records your most recent vote, which means that every new vote will negate all previous votes.

Token Holder Categories

  1. Super Representatives: top 27 individuals among the 127 candidates, voted once every 6 hours. Super Representatives play a key role in governing the TRON community by ensuring basic functions, e.g. block generation and bookkeeping, and obtain corresponding earnings.
  2. Super Representative Candidates: 127 individuals elected through voting by the entire token holder community. Votes are updated once every 6 hours.
  3. Token Holder: Individual holding any amount of TRX.


  1. Candidate Reward(Vote Reward): 127 candidates updated once every 6 hours will share 115,200 TRX. The reward will be split in accordance to the votes each candidate receives. Total reward for candidates will be 168,192,000 TRX each year.
  2. Super Representative Reward(Block Reward): The TRON Protocol network will generate one block every 3 seconds, with each block awarding 32 TRX to Super Representatives. A total of 336,384,000 TRX will be awarded annually to 27 Super Representatives.
  3. There will be no inflation on the TRON network before January 1, 2021, and the TRON Foundation will award all block rewards and candidate rewards prior to that date.

Each time a Super Representative finishes block production, rewards are sent to the sub-account in the superledger. Super Representatives can check, but not directly make use of this asset. A withdrawal can be made once every 24 hours, transferring the reward from the sub-account to the Super Representative’s account.

Rewards Calculation

Total Rewards = Vote Reward + Block Reward

Vote Rewards

  • Vote rewards are 16 TRX every block, with a block generated every 3 seconds1, and 20 blocks per minute.
  • Voting statistics counted every 6 hours, with SRs changing based on vote results.
  • For all 127 SR candidates, the vote rewards per day are calculated as follows: Vote Rewards = 16 (TRX/block) x 20 (blocks/min) x 60 (min/hour) x 6 (hours/election) x 4 (elections/day) = 460,800 (TRX/day)2.
  • For each candidate, the Vote Rewards = 460,800 x (# votes / # total votes)

1.It may take slightly longer than 3 seconds due to machine speed and network jitter.
2.Reward may be less than the theoretical number due to missed blocks.

Block Rewards

  • Block rewards are 32 TRX every block, and SRs create blocks one by one.
  • Block rewards per day: 32 (TRX/block) x 20 (blocks/min) x 60 (min/hour) x 24 (hours/day) = 921,600 (TRX/Day)


Block Rewards Example

Vote Rewards: 460,800 x 14.72% = 67,830 TRX
Block Rewards: 921,600 / 27 = 34,133 TRX
Total Rewards: 67,830 + 34,133 = 101,963 TRX
This SR receives about 101,963 TRX total rewards per day.

For estimating SR voting reward and SR rank by specific votes amount, please use Tron Station voting reward tool to calculate.

Blockchain Explorer

Users can get the following SR information from the TRON blockchain explorer:

  • Delegate’s account address
  • Total votes the delegate received
  • Delegate’s website url
  • Total number of blocks produced by the delegate
  • The total missed blocks of delegate

Super Representative Application Process

All willing users can apply to become Super Representatives, but to prevent malicious attacks, we have set up a threshold for admittance — to run for Super Representative, 9999 TRX in the applicants’ account will be burnt. After successful application, users can run for Super Representatives.

  • Write your personal website address and check information below website address.

Note: 9999 TRX will be paid when users apply to be a SR candidate.

Tronscan provides a way for Super Representatives to publish their information right where the voters are, on Tronscan!

Super Representatives can use this template to build a static page which will be shown on Tronscan. The link will be placed in the voting overview page right next to the name of SR.

The Super Representatives can manage their own content by editing files in the Github repository.

This guide assumes that you already have an account with Super Representative (candidate) status.

  1. Copy/Fork the Template on Github

After forking the repository you will be navigated to your own tronsr-template version of the repository where you can make changes.

2. Fill in the Template

The template can now be modified by editing files on Github.

  • Click the file you want to edit
  • Open edit mode
  • Add some information to the file

Files are written in markdown format. An excellent intro can be found at

  • Update the logo.png and banner.png

Then click on “choose your files” and make sure the logo or banner you want to upload is named logo.png or banner.jpg to overwrite the placeholder images.

After you filled in the template it can now be published on

3. Publish to Tronscan

4. Navigate to

5. Login to your account. In this example it shows using the private key, but you may use any login method.

6. Open account and make sure the “Representative” label is visible

7. Scroll to the bottom and click “Set Github Link”

8. Enter your Github username and then press “Link Github”

9. View your new Page!


The example shows which files are presented where. Whenever the files on Github are modified the page will instantly be updated


Every account in TRON’s network can vote for the Super Representatives they support. Voting requires TRON Power (TP), which is determined by the users’ frozen balance.

TP Calculation: 1 TP for 1 frozen TRX

Once you unfreeze your balance, an equivalent amount of TP is also lost, meaning that previous votes cast may no longer be valid. You can refreeze your balance to revalidate the votes.

Note: TRON network only records the latest votes, so every new allocation of votes you make replaces all previous records.

  • e.g.
freezebalance password 10,000,000 3    // 10 TP for 10 frozen TRX
votewitness password witness1 4 witness2 6 //4 votes for witness1 and 6 votes for witness2
votewitness password witness1 3 witness2 7 // 3 votes for witness1 and 7 votes for witness2

The final result of the above commands is 3 votes for witness1 and 7 votes for witness2.

Freezing/Unfreezing Balance

Why are Tokens Frozen?

The balance freezing mechanism is set up out of two considerations:

  • To prevent malicious spam transactions from clogging the network and causing delayed transaction confirmation.
  • To prevent malicious voting.

Freeze/Unfreeze Mechanism

Once the balance is frozen, the user will receive a proportionate amount of TP and bandwidth. TP represents voting power whereas bandwidth points are used to pay for transactions. Their usage and means of calculation will be introduced in following sections.

Frozen assets are held in your frozen account and cannot be used for trading.

The fixed frozen duration is 3 days, after which you can unfreeze your balance any time you like manually. Balance unfrozen will be transferred back into your current account.

More TP and bandwidth points can be obtained by freezing more balance. The balance can be unfrozen after 3 days from the latest freezing.

  • The freezing command is as follows:
freezebalance password amount time
amount: the unit of frozen balance is sun. The minimum balance frozen is 1,000,000 sun, or 1 TRX.
time: frozen duration lasting from date of freeze and date to unfreeze is 3 days.
  • e.g.

freezebalance password 10_000_000 3

  • Unfreezing command:

unfreezebalance password
