Use case

The wallet/updatebrokerage method is used for:
  • Adjusting witness reward sharing policies to attract more voters.
  • Setting competitive brokerage rates compared to other witnesses.
  • Implementing dynamic reward sharing strategies based on market conditions.
  • Managing witness economics to balance profitability and voter incentives.
Only registered witnesses can update their brokerage rate. The brokerage rate determines what percentage of block rewards the witness keeps (0-100%). A rate of 20% means the witness keeps 20% and shares 80% with voters. Changes may take effect after the next maintenance period.
