c. Lottery Closing
In the event of unexpected circumstances (such as Ethereum protocol
changes) which could affect the lottery and endanger the funds stored in
the Jackpot, the contract allows Admin to withdraw surplus funds from the
Jackpot remaining after settling all outstanding smart contract obligations,
such as:
- Redemption of all remaining SMART Tokens, and
- Payout of all outstanding lottery prizes.
Admin will be allowed to withdraw the surplus from the Jackpot only if
more than 50% of all SMART Tokens are redeemed. In this situation, it will
be clear that lottery security might be vulnerable and that its funds must be
secured. As a consequence, all the surplus funds will be allocated to the
Jackpot of a new, comprehensively secured and updated lottery and the
players and all relevant parties will be notified immediately and continuously
updated during the process.
This is a serious backdoor come on!
It is not a backdoor, it is more than anything a security feature and I am happy that the devs have thought so far ahead.
In the unlikely scenario that Ethereum breaks and is no longer stable enough to host this lottery, then we can move to something like NEM...
As said by glennmatthew this is a security feature that can protect the Jackpot from unexpected circumstances.
More than 50 % of the Tokens must be redeemed to activate this possibility so it's clear that it can be only activated in case of some serious danger.
