Will have to get back to you on Pi, I’ve been redefining the Planck Units through Bitcoin and I already have a solid grasp on the true meaning on Planck length, Planck area, Planck Time, Planck Temp and Planck Energy through the lens of the ledger and the observable nature that time and memory are equal equivalent dimensions of timespace.
Looking at the geometry of a utxo/block, Pi is definitely involved, but I haven’t arrived here yet with enough clarity.
