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…

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.
