The top 27 Super Representatives are responsible for consensus. The list of the top 27 is updated every 6 hours. Using Ledger Live and your hardware wallet, go to the voting page and select your Super Representative(s) then allocate votes to each one. You can vote for up to 5 SRs in one operation. Please note that if you decide to unfreeze TRX, your votes will be automatically reset and your assets become available for transactions once again.
