Integration Flow

Registration

Once built with a compatible DevKit, a subnet registers itself with the Topos Subnet. The subnet registration consists in the submission of a specific transaction that includes the long-lived public key (for certificate authentication). Other subnets in the ecosystem gain access to the long-lived public key by accessing the state of the Topos Subnet and can therefore authenticate future certificates.

Interactions with other subnets

Once registered with the Topos Subnet and known to the rest of the Topos ecosystem, a subnet can start interacting with other subnets, i.e., exchanging cross-subnet messages, by submitting certificates that comply with the specifications defined in the UCI.

To do so, subnet participants establish connections with TCE nodes, to whom they will submit outgoing certificates and listen for new incoming ones.
