1: When one registers as a Delegate - and "Burns" 1,000 SEM, is that permanently destroying the 1,000 SEM or are they locking them up temporarily ? ie. from my wallet perspective, is it just like spending the SEM?
Delegate registration means burning the 1,000 SEMs
permanently destroying it as part of the registration process.
2: If your Delegate gets promoted to Validator do you earn a round-robin reward for new blocks (10 SEM per Block?)
Yes. Validators do earn round-robin reward for new blocks (
10 SEM per Block).
3: Is there any other benefit in being a Delegate, other than having the possibility to become a Validator?
None. Other than having the possibility to become a Validator,
delegates function as normal account.
