Benefits

Value for everyone on the road

Thummer turns the phones that are already everywhere into a shared delivery network, so devices stay simple and cheap, drivers can help, and apps get the data they need.

For device makers and riders

Connectivity without the hardware. No SIM card, cellular plan, gateway or Wi-Fi credentials in each device.
Low power. Bluetooth Low Energy advertising keeps radios simple and batteries long-lived.
Built for small payloads. Telemetry, readings and alerts of up to a few hundred bytes per cargo.
Know it arrived. Signed receipts confirm delivery, or explain a rejection.

For drivers

Help the network by just carrying your phone. Pickups and deliveries happen in the background.
Nothing to see, nothing to worry about. You only ever carry encrypted cargo.
Earn a reputation. Your rating grows with fast, reliable deliveries.
Rewards coming: delivery counts are recorded for future micro-payments and awards.

For consumers

A simple queue. Fetch your riders' messages over HTTPS with an API key, and commit what you've processed.
Addressable. Your 8-byte consumer ID lets any rider send to you.
Private by design. With your public key, riders seal payloads so even Thummer can't read them.
Ready-made app. Thummer Consumer manages keys and stores your decrypted messages.

For everyone

Post-quantum strength. ML-KEM-768 key provisioning and AES-256-GCM encryption from device to cloud.
Fair use. Account classes cap message size and frequency, per minute up to per month.
Quality you can measure. Drivers are rated on speed and reliability.
Density map coming: located pickups will show where more drivers are needed.

Account classes

Each account has a class that sets how large and how frequent its riders' messages can be. Frequency limits apply per rider.

Account classes and their limits
Class	Max message	Per minute	Per hour	Per day	Per week	Per month
Free	128 bytes	2	30	200	1,000	3,000
Standard	256 bytes	10	300	5,000	25,000	100,000
Premium	478 bytes	Unlimited	Unlimited	Unlimited	Unlimited	Unlimited

Message sizes are the payload before encryption. Addressing and sealing use a few bytes of each cargo, so the largest sealed message over Bluetooth is 422 bytes.
