-Mithril is a protocol based on a [Stake-based Threshold Multi-signature scheme](https://iohk.io/en/research/library/papers/mithril-stake-based-threshold-multisignatures/) which leverages the Cardano SPOs to certify data from the Cardano chain in a trustless way. Mithril is currently used in the Cardano ecosystem in order to enable fast bootstrapping of full nodes and enabling secure light wallets.
+Many protocols in the Cardano ecosystem need the capability to diffuse messages in a decentralized manner. However, it is not possible to diffuse any type of message from Cardano block producers to a limited subset of subscribed peers. Nonetheless, the Cardano network has a proven efficient, reliable and secure infrastructure which is used to diffuse a transaction from one peer to all the other peers in the network. This infrastructure can be leveraged to achieve the goal of diffusing other types of messages with the guarantees offered by the Cardano network and a reduced development overhead. 
 
-The Mithril protocol coordinates the collection of individual signatures originating from the signers (run by SPOs) by the aggregators which combine them into Mithril multi-signatures and certificates. In order to be fully decentralized, the protocol needs to rely on a decentralized peer to peer network which, if built from the ground up, would require significant efforts and investment. Furthermore, the majority of SPO's, as the representatives of Cardano's active stake, will have to adopt and operate Mithril nodes alongside their Cardano node. Thus a natural solution is to use the Cardano network layer to significantly facilitate the development of Mithril protocol without a significant impact on the Cardano network or high maintenance efforts for the SPOs.

Mithril will be a fundamental first user of the proposed Decentralized Message Queue and it will be used as an illustrative example throughout this document. 
 
 Other protocols in the Cardano ecosystem, such as Leios and Peras (and probably other protocols in the future), also need the capability to diffuse messages originating from block producers in a decentralized fashion. However, in the Leios and Peras cases, the Cardano node itself is a producer and consumer of these messages. We have taken into consideration this need for a generic solution in the design proposed.
