Haven’t a clue. I presume you’ve heard the carbon copy paper envelope analogy? Signing the envelope copies the signature to the envelope contents but reveals nothing about the contents to the signer.
Discussion
This analogy is generally useful for any kind of blind signing. Dr Calle seems to be looking for details on how tbe blind signing work for WabiSabi.

Dr…missed that.
So…yeah, lol, I doubt he needed the general public hand waving intuitive view! I figured he was (like a lot of us here) a newbie pleb wondering how such a miracle could be possible (a lot of crypto stuff seems unbelievable!).
Lol. Dude did the phd thing and i saw your title and couldnt help myself. 😅
No worries! Hes in fact a lead contributor and perhaps creator of the cashu ecash protocol. I follow him for big brain stuff and occasional snarky notes 🙃
Did you see Max hillebrand’s reply?
This is some seriously awesome tech. Homomorphic encryption lets signers and miners see input = output but not individual values of inputs and outputs. I wonder if it can show input - output = exact number (for miner fees)…
But this is crucial to solving the bitcoin fungibility problem. Which, imho, from a legal perspective, is the biggest elephant in the room…
I saw but am too dumb to grok.
did you see some of the other replies?

Interesting podcast on a cryptographic proof of utxo set. The idea being one can prove validity of utxo set essentially instantly instead of downloading half a terabyte of bitcoin data.
