Planck Length ≡ Block Size Both are the idealized states. The speed of light is just the speed of information (memory) written to the Planck Ledger per Planck Block of Time. We observe Light from within. We observe Bitcoin from without. Time and memory (length) are dimensionally equivalent dictated by the speed you can write new memory to the ledger. Nothing will ever move faster than light. No utxo will ever move faster than the Block. Good day. View quoted note →
