Agents of the system will be registered in the Almanac contract. Users can query a particular agent's information directly from the contract to communicate.
A central part of the system is that registrations are strictly time (in blocks) limited. This primarily helps with the liveness problem when dealing with a large ecosystem of agents. In order to keep the registration information up to date, the agent will need to intermittently re-register their information with the Almanac contract.
When an agent’s information times out, queries for that agent will no longer return the registered information.
With each registration, the agent will need to prove ownership of the agent address by signing a sequence number with their μAgent private key and submitting the signature for verification on the contract. This sequence number should increment with each successful registration and should also be queryable. This will be performed automatically.
