Bearers
The bearers (REQ-019) are how a Nomad reaches the mesh. OpenYield ships six bearers through a single Unified Bearer Layer: the mesh does not care which bearer a Holder uses — first-to-deliver-wins, and a Nomad can switch bearers without switching identity. The Mirror mirrors the canonical state to every bearer so a Nomad can read the mesh's real return on any of them.
The six bearers
| Bearer | Live in v0.2 | What it is |
|---|---|---|
| Internet | yes | the default bearer; OY Chain over the open internet. |
| OY-BLE | yes | Bluetooth Low Energy; short-range, peer-to-peer, no phone plan. |
| OY-WiFi-Direct | yes | WiFi Direct; local mesh without an access point. |
| OY-LR | yes | Long Range radio (LoRa-class); long-distance, low-bandwidth, surveillance-resistant. |
| OY-SAT | coming (v0.3 P4) | satellite; offline coverage via a satellite constellation. |
| OY-QR | coming (v0.3 P4) | signed QR code; one-shot offline transfer scanned by a peer. |
What this means for a Nomad
A Nomad does not pick "the right bearer". The four already-live bearers (Internet, OY-BLE, OY-WiFi-Direct, OY-LR) cover the everyday situations: on the open internet, in a room with another Holder, in a local group with no router, or kilometers away with no infrastructure. OY-SAT and OY-QR extend that to true-offline paths and are coming in the next phase.
Surveillance resistance
OY-LR, OY-BLE, OY-WiFi-Direct, OY-SAT, and OY-QR are designed to be surveillance-resistant: a Nomad can send or receive value without a phone plan, a SIM, or a custodial on-ramp. The bearer is the transport; the Reach is the identity; the Stash is the storage. None of them depends on a custodial position.
First-to-deliver-wins
The Unified Bearer Layer is first-to-deliver-wins: if a Nomad sends a transfer over two bearers at once, the mesh accepts the first one that arrives and drops the duplicate. This is why a Nomad can switch bearers mid-transfer without double-spending.
See Watchers & Mirror for how the canonical state is mirrored to every bearer, and Maps & Pay for how a Nomad uses a bearer to find and pay for services.
