I'm looking at the #powping transaction structure.
out[0] looks like the public key of the paymail and a signature for out[1]
out[1] looks like the message and the metadata
I'm wondering which public key is being used. I had a look at my money button account and the first public key in the derivation path of m/44'/0'/0' from the mnemonic but it doesn't match.
I haven't looked into the bsvalias protocol, so maybe that's where I'm missing something. Can someone help me understand which private key is signing my powping messages?
