Just bump it.
the sovereign credentiaRing
How you greet someone decides what you share. A handshake hands over your work card; a fistbump, your gym chat; a pinky-link, your Snap. The gesture picks the tier, no app, no cloud, no one in the middle.
You never overshare, because the gesture and the time pick the tier for you.
The ring feels the difference: a jog, a jiggle and a judder are three different keys. Start with the classics; the rest, the world writes.
Remember the secret handshakes you discovered with your friends growing up? Yeah, neither do we 💀. Submit yours and jog our memory.
Submit a handshake →Ship the cheap proof, build the real product, leave room to grow. The gesture engine lives in Sigma; health is a tier you reach for later, if ever.
Sigma is a ring that already exists for ~$13, plus the firmware only we write. The accelerometer is already on the board, so gesture sensing is a software play, not a hardware program. The PPG (05) belongs to Omega, later.
No camera, no cloud, no guesswork. The accelerometer already on the ring reads the shape of the motion, and plain on-ring logic reads the difference. A fistbump and a handshake don't look alike to the silicon.
A ten-second calibration bump when you first pair learns your hand, so a featherweight and a linebacker both read clean. v1 nails the big three (bump, shake, pound) at ~85-90% with plain threshold logic: no machine learning, no gyroscope. It's the trick the Bump app proved in 2009 across 125 million downloads, except it happens ring-to-ring, and nothing ever leaves your finger.
Sigma doesn't need health to be worth wearing. But the same ring body can take a PPG optical sensor, and then Omega reads your body the way Oura does, except the data never leaves your finger without your key. On-device, open, no subscription, built only if Sigma earns it.
The best relationship you can have with someone else's data is none at all.
The firmware and the app are auditable. No black box on your hand, fork it, read it, trust it.
Identity is decentralized (Nostr / DIDs); your profile lives on a page you host. We run no server that holds you.
Buy the ring once, pay nothing forever. Nothing to subscribe to, nothing to breach, nothing to shut down.
Your body + your contacts, escrowed on their servers. Cancel and it goes dark.
Your finger holds the only copy that matters. We literally can't sell what we never hold.
BOM sourcing, fab & assembly, landed cost & unit economics, the funding case. Turns the spec into a manufacturable, costed product.
Firmware, the gesture classifier, the app, the Nostr/DID identity layer, self-hosted profiles. The defensible part.
The cheapest possible proof. Hand them out, watch people bump. If it lands, we build Sigma, the real product, with real numbers, and Bob's name is on the box.
