@ -117,9 +117,11 @@ To allow for subscriptions to rotate quickly and randomly, a backbone is formed
This backbone is based on a pure function of the *node* identity and time:
- Nodes can be found *without additional discovery overhead*:
peers on a vertical topic can be found by searching the local peerstore for identities that hash to the desired topic(s).
peers on a vertical topic can be found by searching the local peerstore for identities that hash to the desired topic(s),
assuming the peerstore already has a large enough variety of peers.
- Nodes can be held accountable for contributing to the backbone:
peers that particpate in DAS but are not active on the appropriate backbone topics can be scored down.
*Note: This is experimental, DAS should be light enough for all participants to run, but scoring needs to undergo testing*
A node should anticipate backbone topics to subscribe to based their own identity.
These subscriptions rotate slowly, and with different offsets per node identity to avoid sudden network-wide rotations.
