[shuse2]

Description

Update DPoS system with 2 new transactions vote and unlock. Also, implement BFT punishment for the misbehaviour.

Motivation

• Uniform ordering of delegates list
• Use Randao-based scheme to include standby delegates and reorder delegate list
• Introduce vote locking periods and new vote weight definition
• Punish BFT violations

Acceptance Criteria

To conclude this epic, following LIP must be implemented:

• Uniform ordering of delegates list
• Use Randao-based scheme to include standby delegates and reorder delegate list
• Introduce vote locking periods and new vote weight definition
• Punish BFT violations
