Question about ECC Point Addition
I have a question about ECC Point addition from the intro document in the

> private key *r* used as a *blinding factor*.
And this curve G is used for Point addition:

the construction Greg Maxwell made in his Confidential Transactions paper
for Pedersen Commitments:
If it is not, then is G a different curve altogether? As in, not secp256k1?
In that case, how is Point Addition defined between points on different
