Stripe's fraud detection heuristics are neither sophisticated nor particularly effective.
Judicious use of DNSBLs, port scanning and latency measurements, three measures which shouldn't take a competent technician more than a few days to knock together, will outperform Stripe.
I developed narcolepsy in my teens and I can absolutely relate to how you feel. Everyone just thought I was lazy, malingering or, in the case of my general physician, depressed. It took years before I could even see a neurologist, after which an official diagnosis was quickly made.
If you're not already on sodium oxybate (Xyrem), I can't recommend it enough; it's the only thing that puts me in a sound, restorative sleep for more than a few hours.
I'm in the UK where prescriptions for Xyrem are almost impossible to obtain. Fortunately, the precursors for its active ingredient, GHB, are inexpensive and easy to acquire, so I just synthesize it myself. Technically it's illegal, but it would take an especially brave magistrate to convict me for having to overcome deficiencies in the NHS.
Using PoW `Medallions' on top of a PoW blockchain to prevent Sybil attacks seems redundant. Why not just require Ether commitments from bandwidth providers? Users can then set a configurable threshold for commitment lengths/amounts according to individual needs.
This is the first I'm hearing of probabilistic payments. Are you aware of any other systems, proposed or operational, using this to pay for bandwidth? It seems like a natural fit.
