Learning objectives
- 01Configure delegation, unbonding period and commissions
- 02Compute your chain's security budget
- 03Explain the role of the unbonding period
Guided lab
Configure staking, delegate, then undelegate and watch the unbonding period at work.
Independent lab
Cost out a one-third-of-stake attack against your own chain.
Security angle
Too short an unbonding period makes an attack recoverable, and therefore rational.
Assessment
Security-budget note, assessed on its calculation method.
