Super Representative¶
How to Become a Super Representative¶
Block producers in the TRON network, also called super representatives, are elected by voting. Any account can apply to become a super representative candidate by paying 9999 TRX and then participate in the super representative election. Any account can vote for super representative candidates, and the top 27 candidates with the most votes become super representatives, and they have the right to produce blocks. Super representative needs to run a TRON node to participate in block production, and will also receive block rewards and voting rewards. Voters who vote to super representatives will receive voting rewards.
The super representative candidates ranked 28th to 127th are also called super representative partners. Super representative partners do not participate in block production and packaging transactions, but will receive voting rewards. Voters who vote to super representative partners will also receive voting rewards.
The votes will be counted every 6 hours, so super representatives and super representative partners will be changed every 6 hours.
Super Representative Election¶
To vote, you need to have TRON Power(TP). To get TRON Power, you need to stake TRX. Every 1 staked TRX accounts for one TRON Power(TP). Every account in TRON network has the right to vote for a super representative candidate. After you unstake your staked TRX, you will lose the corresponding TRON Power(TP), so your previous vote will be invalid.
Note: Only your latest vote will be counted in TRON network which means your previous vote will be over written by your latest vote.
Example (Using wallet-cli):
> freezebalancev2 10,000,000 3 // Stake 10 TRX to get 10 TRON Power(TP)
> votewitness SR1 4 SR2 6 // Vote 4 votes for SR1, 6 votes for SR2
> votewitness SR1 3 SR2 7 // Vote 3 votes for SR1, 7 votes for SR2
The final output above is: Vote 3 votes for SR1, 7 votes for SR2.
Rewards¶
Brokerage of SRs and SR partners¶
The default ratio is 20%. Super representatives and super representative partners can query the brokerage ratio through the wallet/getBrokerage interface, and can also modify the brokerage ratio through the wallet/updateBrokerage interface.
If a SR(Super Representatives) get 20% of the rewards, and the other 80% will be awarded to the voters. If the brokerage ratio is set to 100%, the rewards are all obtained by the SR; if set to 0, the rewards are all sent to the voters.

Every SR has the right to create and vote a proposal. The proposal will be passed after it gets at least 18 approves from the super representatives and will become valid in the next maintenance period.
