HI,

Which altcoins support signing and verifying messages? And what software / wallet for these altcoins provides this service?

So far, my research has thrown these altcoins up as providing ability to sign anbd verify messages (mainly to prove ownership of address):

1. Dash
2. Monero
3. ZCash
4. DogeCoin
5. BitShares
6. Lisk
7. Peercoin

Are there any I am missing out? (Litecoin?)

Also- as a noob to ethereum,  I understand that ethereum provides this capability too. But pther tokens built on top of ethereum - how many and how do they provide this capability? I am talking about tokens like: Golem, Gnosis, Stellar, Augur, Waves, MaidSafeCoin, DigixDao, DigiByte, Ardor, Iconomi, Melon, Reddcoin etc

Thanks.
