Changing Delegate Take

[distributedstatemachine]

Description

Currently, the delegation rewards distribution system in our blockchain project has a limitation where delegates' commission rates (takes) are hardcoded at 18%. This inflexibility prevents delegates from adjusting their commission rates based on market conditions and their individual strategies.

As a result, delegates often resort to off-chain agreements and rebate systems to attract delegators and remain competitive. This creates market inefficiencies and hinders the overall user experience within our ecosystem.

Implementing the ability for delegates to alter their commission rates within the defined range would provide significant value to both delegates and delegators, enabling them to make informed decisions and adapt to evolving market dynamics.

Acceptance Criteria

• Delegates should be allowed to set their commission rates (takes) within the range of 0% to 18%.
• To prevent frequent changes and ensure stability, delegates should only be allowed to increase their commission rates once every 30 days (monthly).
• The new commission rate should be applied to future rewards distributions and not affect previously distributed rewards.

Tasks

• Implement a function in the delegation contract to allow delegates to change their commission rates (takes) within the specified range.
• Add necessary checks to ensure that delegates can only increase their commission rates once every 30 days.

Additional Considerations

• Do we need some notification system to broadcast delegate rate changes ?
