Is it possible to break this down and try to simplify the differences? I am just trying to make a simplified summary here.
Monero is POW
Shadowcash is POS
Monero is building new protocol
Shadowcash is building on top of bitcoin protocol
Monero uses viewkeys to make wanted tx public
Shadowcash uses public and private tx
Am I missing anything?
Monero is built on top of cryptonote, they are not building something from scratch.
Monero and Shadow have private transactions, you can use a view key to show the transactions only to the persons you want (it's not the same name for shadow, but works the same)
Shadow also has public transactions.
This leads to the question asked by litebit
Debatable topic: Monero's single token (100% private) system to Shadow's dual token (public & 100% private) system.
- Which is better and do you really need 2 coins to do what 1 can do flawlessly?
This is a serious advantage for Shadow.
Why having two types of tx instead of one ?
Look at monero blockchain size. The private tx are way bigger than the public one
By keeping the two types of tx, you can avoid to surcharge the blockchain with private ones when they are not needed.
You can also imagine a lot of applications using that possibility of having both private and public tx.
Monero blockchain size might become a huge problem if it become really successful
