Unscoped traffic stays out
Blocked everywhere, not just at the border. Non-compliant repeaters get herd immunity, so it never spreads.
MeshCore in Scotland/Peers
Peering on the Scottish mesh
A peer is another MeshCore network we join up with, so messages can cross between our meshes. It is reciprocal: each side carries the other’s region, and only that region’s traffic crosses.

our neighbours, and their scoped traffic live by region

What peering means
reciprocal, and scoped to a region
Every network runs its own region. Ours is sco. A peer carries sco, we carry theirs, and a message on a shared region floods both meshes and stops at the edge. Nothing else crosses.
The map above is live: each dot a node, each line a link, coloured by region. sco fills the central belt, ioi covers Ireland, eng-ne holds Teesside, wls lights up Anglesey.

How we choose peers
kept deliberately small and local
01
Direct neighbours
The meshes next to us, where our coverage actually reaches theirs.
02
A peer's small neighbour
A small network just beyond a peer, where it is the natural next hop — like the Isle of Man.
03
Reciprocal and scoped
Two-way, and limited to agreed regions. We carry theirs, they carry sco, nothing else.
Carrying a region costs airtime on every repeater, so we add a peer only when it is a true neighbour.
Why we peer this way
scoping keeps it small, safe, and easy to undo
Their nodes, not their peers’
A peer’s nodes advert into ScotMesh. Networks beyond the peer stop at our border; only chat crosses, on the shared scope.
Easy to dial back
At the border choke point, cap how many hops a scoped packet may arrive with, or drop the region entirely — cut in minutes, either side.
Floods are capped
We run 3-byte paths, so any flood caps at 21 hops and stops being forwarded.
Loops are dropped
Loop detection is enforced across the mesh — a packet that circles back is dropped, not amplified.

If your network borders ours, or a peer's, come and say hello. Peering is a quick change on both sides once we have agreed the regions.
