Crate mithril_aggregator

Mithril aggregator The Aggregator is responsible for:

• registering signers
• producing aggregate multi-signatures
• creating, storing & serving the certificate chain
• creating, storing & serving certified snapshots

This crate is divided in two parts: a HTTP server that exposes an API to communicate with signers and a Runtime that tracks the blockchain to provide signed certificates. You can find more information on how it works reading the documentation website.
