+# DON Composition
+
+`p2pmq` enables to compose a network of peers cross DONs (Decentralized Oracles Network), acting as a decentralized message bus for DON to DON communication.
+
+The following diagram illustrates the composition of a network of `p2pmq` peers across DONs:

+
+<br />
+
+## Messaging
+
+DONs communication is based on OCR reports, which are broadcasted over some topic rather than on-chain transmission.
+
+The reports MUST be signed by a quorum of the DON's nodes, otherwise they are considered invalid and any nodes that broadcast them are penalized.
+
+**NOTE** `p2pmq` enables to aid in a custom validation before processing and propagating messages to the network.
+
+**TBD** signature validation cross DONs.
