+## Abstract
+
+Discv5 is an extensible protocol which allows building new protocols on top of it. We propose a generic framework for building new distributed hash table (DHT) networks on top of Discv5 referred to as the _Portal Wire Protocol_
+
+## Motivation
+
+Discv5 is implemented in many languages, has built in packet encryption, used by consensus clients, and allows building sub-protocols using its _TalkRequest_ message type.
+
+With the ubiquity of Discv5 in Ethereum and it being implemented in many languages, building new protocols using Discv5 as a base is beneficial as it enables quicker implementation times, stability as Discv5 is already used in production, as well as inheriting improvements and optimizations discovered by Discv5.
+
+When building new DHT sub-protocols on Discv5, new sub-protocols often share the same primitive message types. By defining the framework _Portal Wire Protocol_, new networks can be built without re-implementing the DHT primitives reducing the development time and inheriting the performance optimizations of the base _Portal Wire Protocol_ implementation.
+
+## Specification
+
+Specification of the _Portal Wire Protocol_ are on [/ethereum/portal-network-specs](https://github.com/ethereum/portal-network-specs/blob/4ce803e90a24becc9f76e7c18dc188ccf84e9f8e/portal-wire-protocol.md).
+
+## Rationale
+
+Reducing the amount of duplicate code for primitive DHT functions, to enable cleaner and quicker development of sub-protocols over Discv5
