Confidential peg-in transaction about elements HOT 11 OPEN

Hey @alexqrid! Nice find, normally pegins have explicit (unblinded) outputs.

I'm wondering why its amount is confidential, if the output of BTC transaction is not confidential?

The output on the liquid side can be blinded, but obviously not on the bitcoin side.

so why the node is not returning amount of this peg-in input, if we can get it from the BTC output?

Only the wallet that created the output has the blinding keys (unless they get exported and shared), and the output asset/amount can't be unblinded without the blinding keys.

The transaction has two confidential outputs, so in principle, the pegin amount could be split in any way between the two, and there's no way to tell :).

In practice because one output is OP_RETURN, I think we can assume that its value is 0 and the entire pegin went to the other output.

I think that the Elements wallet will do this if you do a peg-in to a confidential address.
