What are Confidential Transactions and Confidential Assets?
Especially the latter is interesting.
Thanks
Confidential Transactions: I think this was invented by Greg Maxwell. The idea and to sum up all the technical details, is to hide the amount of BTC that are being transacted.
So if for example you make a transaction of 1BTC, if you check on the blockchain, it wouldn't show up what amount of BTC that tx contains. I don't know how it would look like actually. "X BTC"? I don't know how it would show up.
This will require segwit which luckily we are getting soon. Im not sure if it also requires sidechain or this Mimblewimble.
CA, that i have never heard off.
