IMO the thread is asking the wrong question ("can micropayments work?") They can, but we need to start with first principals on what's technically necessary to move value, and what can we toss out (from both traditional/card systems and crypto). You need a linearly scalable state machine and a means of orchestrating the changes in that state between actors. Everything else (kyc, fraud protections, etc.) is secondary. Machines are likely going to be paying extreme small amounts between each other, so its highly questionable whether that state machine (a) needs to protect for fraud at .001 cents per tx and (b) whether a machine, acting on its own accord, spending .001 was contemplated during the construction of the bank secrecy act (which had the de minimis oversight of transactions at ~82k USD in 2026 values). Ensure no double spend, ensure that the machines can move value as needed, change the state. Ensure that the system scales as much as the volumes of transactions needed. And charge effectively free rates (we're at 10m tx/usd). Lots more to build here, but we're not far off. (and we're launching soon at radiustech.xyz). Come check us out.
