user63374: Is there any dash adddress where all outputs are guaranteed to stay unspent?
Like bitcoin 1BitcoinEaterAddressDontSendf59kuE in dash?

user51948: Technically, there is nothing special about the 1BitcoinEaterAddressDontSendf59kuE address, if someone by chance did manage to find the private key for it they could spend the bitcoins there. The reason it is trusted as unspendable is that to find a private key for a given address is impossible with our current knowledge of elliptic curve cryptography (and RIPEMD-160), if it was possible then bitcoin along with many other security systems would be completely broken. That specific address is trusted because it is completely made up of english words other than the checksum at the end (which is there to make it a valid bitcoin address), so it can be basically guaranteed that no one has the private key for it.
So technically any valid address for dash that you generate would be equally unspendable without the corresponding private key, and thus an address of this sort could easily be created for dash by coming up with a similar string as the bitcoinEater, make sure its obviously picked based on the address itself so people will believe that you don't have the private key for it, e.g. DashDevourerAddressDontSend, and then generate the appropriate checksum with the right prefix for it to make it a valid address.
