-  <appendix|Network Messages><label|sect-network-messages>
-
-  In this section, we will specify various types of messages which the
-  Polkadot Host receives from the network. Furthermore, we also explain the
-  appropriate responses to those messages.
-
-  <\definition>
-    A <strong|network message> is a byte array, <strong|<math|M>> of length
-    <math|<around*|\<\|\|\>|M|\<\|\|\>>> such that:

-    </equation*>
-
-    \;
-  </definition>
-
-  The body of each message consists of different components based on its
-  type. The different possible message types are listed below in Table
-  <reference|tabl-message-types>. We describe the sub-components of each
-  message type individually in Section <reference|sect-message-detail>.

   <section|Introduction>
 
   The Polkadot network is decentralized and does not rely on any central
-  authority or entity in order to achieve a its fullest potential of provided
-  functionality. Each node with the network can authenticate itself and its
-  peers by using cryptographic keys, including establishing fully encrypted
-  connections. The networking protocol is based on the open and standardized
-  <verbatim|libp2p> protocol, including the usage of the distributed Kademlia
-  hash table for peer discovery.
+  authority or entity in order to achieve its fullest potential of provided
+  functionality. The networking protocol is based on a family of open
+  protocols, including the distributed Kademlia hash table which is used for
+  peer discovery.
 
-  <subsection|External Documentation>
+  This chapter walks through the behavior of the networking implemenation of
+  the Polkadot Host and defines the network messages. Implementation details
+  of the used <verbatim|libp2p> protocols are specified in external sources
+  as described in Section <reference|sect-networking-external-docs>.

   The completeness of implementing the Polkadot networking protocol requires
   the usage of external documentation.

-  <subsection|Discovery mechanism>
+  <subsection|Node Identities>
 
-  The Polkadot Host uses varies mechanism to find peers within the network,
-  to establish and maintain a list of peers and to share that list with other
-  peers from the network.
+  Each Polkadot Host node maintains a ED25519 key pair which is used to
+  identify the node. The public key is shared with the rest of the network
+  which allows nodes to establish secure communication channels.\ 
 
-  The Polkadot Host uses various mechanism for peer dicovery.
+  Each node must have its own unique ED25519 key pair. When two or more nodes
+  use the same key, the network will interpret those nodes as a single node,
+  which will result in undefined behavior and can result in equivocation.
+  Furthermore, the node's <verbatim|PeerId> as defined in Definition
+  <reference|defn-peer-id> is derived from its public key. <verbatim|PeerId>
+  (<reference|defn-peer-id>) is used to identify each node when they are
+  discoved in the course of the discovery mechanism described in Section
+  <reference|sect-discovery-mechanism>.
 
-  <\itemize>
-    <item>Bootstrap nodes - hard-coded node identities and addresses provided
-    by network configuration itself. Those addresses are selected an updated
-    by the developers of the Polkadot Host. Node addresses should be selected
-    based on a reputation metric, such as reliability and uptime.
+  <\definition>
+    <label|defn-peer-id>The Polkadot node's <verbatim|PeerId>, formally
+    referred to as <math|P<rsub|id>>, is derived from the ED25519 public key

-    <item>mDNS - performs a broadcast to the local network. Nodes that might
-    be listing can respond the the broadcast.
+  The Polkadot Host uses various mechanisms to find peers within the network,
+  to establish and maintain a list of peers and to share that list with other
+  peers from the network, as follows:
 
-    <item>Kademlia requests - Kademlia supports <verbatim|FIND_NODE>
+  <\itemize>
+    <item><strong|Bootstrap nodes> are hard-coded node identities and

+
+    <item><strong|mDNS> protocol which performs a broadcast to the local
+    network. Nodes that might be listening can respond the the broadcast.
+    <hlink|The libp2p mDNS specification|https://github.com/libp2p/specs/blob/master/discovery/mdns.md>
+    defines this process in more detail. This protocol is an optional
+    implementation detail for Polkadot Host implementers and is not required
+    in order to participate in the Polkadot network.
+
+    <item><strong|Kademlia requests> invoking Kademlia <verbatim|FIND_NODE>
     requests, where nodes respond with their list of available peers.
+    Kademlia requests are performed on a specific substream as described in
+    Section <reference|sect-protocols-substreams>.
   </itemize>
 
-  <subsection|Connection establishment>
-
-  The Polkadot Host can establish a connection with any peer it knows the
-  address. <verbatim|libp2p> uses the <verbatim|multistream-select> protocol
-  in order to establish an encryption and multiplexing layer. The Polkadot
-  Host supports multiple base-layer protocols:
+  <subsection|Connection establishment><label|sect-connection-establishment>
+
+  Polkadot nodes connect to peers by establishing a TCP connection. Once
+  established, the node initiates a handshake with the remote peer's on the
+  encryption layer. An additional layer on top of the encryption layer, known
+  as the multiplexing layer, allows a connection to be split into substreams,
+  as described by the <hlink|yamux specification|https://docs.libp2p.io/concepts/stream-multiplexing/#yamux>,
+  either by the local or remote node.
+
+  The Polkadot node supports two types of substream protocols. Section
+  <reference|sect-protocols-substreams> describes the usage of each type in
+  more detail:
+
+  <\itemize-dot>
+    <item><strong|Request-Response substreams>: After the protocol is
+    negotiated by the multiplexing layer, the initiator sends a single
+    message containing a request. The responder then sends a response, after
+    which the substream is then immediately closed. The requests and
+    responses are prefixed with their <hlink|LEB128|https://en.wikipedia.org/wiki/LEB128>
+    encoded length.
+
+    <item><strong|Notification substreams>. After the protocol is negotiated,
+    the initiator sends a single handshake message. The responder can then
+    either accept the substream by sending its own handshake, or reject it by
+    closing the substream. After the substream has been accepted, the
+    initiator can send an unbound number of individual messages. The
+    responder keeps its sending side of the substream open, despite not
+    sending anything anymore, and can later close it in order to signal to
+    the initiator that it no longer wishes to communicate.
+
+    Handshakes and messages are prefixed with their
+    <hlink|LEB128|https://en.wikipedia.org/wiki/LEB128> encoded lengths. A
+    handshake can be empty, in which case the length prefix would be
+    <verbatim|0>.
+  </itemize-dot>
+
+  Connections are established by using the following protocols:
+
+  <\itemize-dot>
+    <item><verbatim|/noise> - a protol that is announced when a connection to
+    a peer is established.
+
+    <item><verbatim|/multistream/1.0.0> - a protocol that is announced when
+    negotiating an encryption protocol or a substream.
+
+    <item><verbatim|/yamux/1.0.0> - a protocol used during the
+    <verbatim|mplex> or <verbatim|yamux> negotiation. See Section
+    <reference|sect-protocols-substreams> for more information.
+  </itemize-dot>
+
+  The Polkadot Host can establish a connection with any peer of which it
+  knows the address. The Polkadot Host supports multiple networking
+  protocols:
 
   <\itemize>
-    <item>TCP/IP - addresses in the form of <verbatim|/ip4/1.2.3.4/tcp/>
-    establish a TCP connection and negotiate a encryption and multiplexing
-    layer.
+    <item><strong|TCP/IP> with addresses in the form of
+    <verbatim|/ip4/1.2.3.4/tcp/> to establish a TCP connection and negotiate
+    an encryption and a multiplexing layer.
 
-    <item>Websockets - addresses in the form of <verbatim|/ip4/1.2.3.4/ws/>
-    establish a TCP connection and negotiate the Websocket protocol within
-    the connection. Additionally, a encryption and multiplexing layer is
-    negotiated within the Websocket connection.
+    <item><strong|Websockets> with addresses in the form of
+    <verbatim|/ip4/1.2.3.4/ws/> to establish a TCP connection and negotiate
+    the Websocket protocol within the connection. Additionally, an encryption
+    and multiplexing layer is negotiated within the Websocket connection.
 
-    <item>DNS - addresses in form of <verbatim|/dns/website.domain/tcp/> and
+    <item><strong|DNS> addresses in form of
+    <verbatim|/dns/website.domain/tcp/> and
     <verbatim|/dns/website.domain/ws/>.
   </itemize>
 
+  The addressing system is described in the <hlink|libp2p
+  addressing|https://docs.libp2p.io/concepts/addressing/> specification.
   After a base-layer protocol is established, the Polkadot Host will apply
-  the Noise protocol.
-
-  <subsection|Substreams>
+  the Noise protocol to establish the encryption layer as described in
+  Section <reference|sect-encryption-layer>.
+
+  <subsection|Encryption Layer><label|sect-encryption-layer>
+
+  Polkadot protocol uses the <samp|<verbatim|libp2p>> Noise framework to
+  build an encryption protocol. The Noise protocol is a framework for bulding
+  encryption protocols. <verbatim|libp2p> utilizes that protocol for
+  establishing encrypted communication channels. Refer to the <hlink|libp2p
+  Secure Channel Handshake|https://github.com/libp2p/specs/tree/master/noise>
+  specification for a detailed description.
+
+  Polkadot nodes use the <hlink|XX handshake
+  pattern|https://noiseexplorer.com/patterns/XX/> to establish a connection
+  between peers. Three following steps are required to successfully complete
+  the handshake process:
+
+  <\enumerate-numeric>
+    <item>The initiator generates a keypair and sends the public key to the
+    responder. The <hlink|Noise specification|https://github.com/libp2p/specs/tree/master/noise>
+    and the <hlink|libp2p PeerId specification|https://github.com/libp2p/specs/blob/master/peer-ids/peer-ids.md>
+    describe keypairs in more detail.
+
+    <item>The responder generates its own keypair and sends its public key
+    back to the initiator. After that, the responder derives a shared secret
+    and uses it to encrypt all further communication. The responder now sends
+    its static Noise public key (which may change anytime and does not need
+    to be persisted on disk), its <verbatim|libp2p> public key and a
+    signature of the static Noise public key signed with the
+    <verbatim|libp2p> public key.
+
+    <item>The initiator derives a shared secret and uses it to encrypt all
+    further communication. It also sends its static Noise public key,
+    <verbatim|libp2p> public key and a signature to the responder.
+  </enumerate-numeric>
+
+  After these three steps, both the initiator and responder derive a new
+  shared secret using the static and session-defined Noise keys, which are
+  used to encrypt all further communication.
+
+  <subsection|Protocols and Substreams><label|sect-protocols-substreams>
 
   After the node establishes a connection with a peer, the use of
-  multiplexing allows the Polkadot Host to open substreams. Substreams allow
-  the negotiation of <with|font-shape|italic|application-specific protocols>,
-  where each protocol servers a specific utility.
-
-  The Polkadot Host adoptes the following, standardized <verbatim|libp2p>
-  application-specific protocols:
+  multiplexing allows the Polkadot Host to open substreams. <verbatim|libp2p>
+  uses the <hlink|<verbatim|mplex> protocol|https://docs.libp2p.io/concepts/stream-multiplexing/#mplex>
+  or the <hlink|<verbatim|yamux> protocol|https://docs.libp2p.io/concepts/stream-multiplexing/#yamux>
+  to manage substream and to allow the negotiation of
+  <with|font-shape|italic|application-specific protocols>, where each
+  protocol servers a specific utility.
+
+  The Polkadot Host uses multiple substreams, where its usage depends on a
+  specific purpose. Each substream is either a <em|Request-Response
+  substream> or a <em|Notification substream>, as described in Section
+  <reference|sect-connection-establishment>.
 
   <\itemize>
     <item><verbatim|/ipfs/ping/1.0.0> - Open a substream to a peer and
     initialize a ping to verify if a connection is till alive. If the peer
-    does not respond, the connection is dropped.
+    does not respond, the connection is dropped. This is a
+    <em|Request-Response substream>.
 
     <item><verbatim|/ipfs/id/1.0.0> - Open a substream to a peer to ask
-    information about that peer.
+    information about that peer. This is a <em|Request-Response substream>.
 
-    <item><verbatim|/dot/kad/> - Open a substream for Kademlia
-    <verbatim|FIND_NODE> requests.
+    <item><verbatim|/dot/kad> - Open a substream for Kademlia
+    <verbatim|FIND_NODE> requests. This is a <em|Request-Response substream>,

   </itemize>
 
-  Additional, non-standardized protocols:
-
   <\itemize>
     <item><verbatim|/dot/sync/2> - a request and response protocol that
-    allows the Polkadot Host to perform information about blocks.

-
-    <item><verbatim|/dot/transactions/1> - a notification protocol which

+  <strong|Note>: the <verbatim|/dot/> prefixes on those substreams are known
+  as protocol identifiers and are used to segregate communications to
+  specific networks. This prevents any interference with other networks.
+  <verbatim|/dot/> is used exclusively for Polkadot. Kusama, for example,
+  uses the <verbatim|/ksmcc3/> protocol identifier.
+
+  <subsection|Network Messages><label|sect-network-messages>
+
+  The Polkadot Host must actively communicate with the network in order to
+  participate in the validation process or act as a full node.
+
+  <strong|Note>: The Polkadot network originally only used SCALE encoding for
+  all message formats. Meanwhile, Protobuf has been adopted for certain
+  messages. The encoding of each message is explicitly mentioned in their
+  corresponding definition. Encoding and message formats are subject to
+  change.
+
+  <subsubsection|Announcing blocks>
+
+  When the node creates or receives a new block, it must be announced to the
+  network. Other nodes within the network will track this announcement and
+  can request information about this block. The mechanism for tracking
+  announcement and requesting the required data is implementation specific.
+
+  Block announcements, requests and responses are sent over the
+  <verbatim|/dot/block-announces/1> substream as defined in Definition
+  <reference|defn-block-announce-handshake>.

+
+  Transactions as defined and described in Section
+  <reference|sect-extrinsics> are sent directly to peers with which the
+  Polkadot Host has an open transaction substream, as defined in Definition
+  <reference|defn-transactions-message>. Polkadot Host implementers should
+  implement a mechanism which only sends a transaction once to each peer and
+  avoids sending duplicates. Sending duplicate transactions might result in
+  undefined consequences such as being blocked for bad behavior by peers.
+
+  The mechanism for managing transactions is further described in Section
+  <reference|sect-extrinsics>.
+
+  <\definition>
+    <label|defn-transactions-message>The <strong|transactions message> is the
+    structure of how the transactions are sent over the network. It is
+    represented by <math|M<rsub|T>> and is defined as follows:
+
+    <\equation*>
+      M<rsub|T>\<assign\>Enc<rsub|SC><around*|(|C<rsub|1>,\<ldots\>,C<rsub|n>|)>

+    <\equation*>
+      C<rsub|i>\<assign\>Enc<rsub|SC><around*|(|E<rsub|i>|)>
+    </equation*>
+
+    Where each <math|E<rsub|i>> is a byte array and represents a sepearate
+    extrinsic. The Polkadot Host is agnostic about the content of an

-  <section| To be migrated<label|sect-network-interactions>><label|network-protocol>
-
-  <\warning>
-    Polkadot network protocol is work-in-progress. The API specification and
-    usage may change in future.
-  </warning>
-
-  This chapter offers a high-level description of the network protocol based
-  on <cite|parity_technologies_substrate_2019>. Polkadot network protocol
-  relies on <em|libp2p>. Specifically, the following libp2p modules are being
-  used in the Polkadot Networking protocol:
-
-  <\itemize>
-    <item><samp|mplex.>
-
-    <item><samp|yamux>
-
-    <item><samp|secio>
-
-    <item><samp|noise>
-
-    <item><samp|kad> (kademlia)
-
-    <item><samp|identity>
-
-    <item><samp|ping>
-  </itemize>
-
-  For more detailed specification of these modules and the Peer-to-Peer layer
-  see libp2p specification document <cite|protocol_labs_libp2p_2019>.
-
-  <subsection|Node Identities and Addresses>
-
-  Similar to other decentralized networks, each Polkadot Host node possesses
-  a network private key and a network public key representing an ED25519 key
-  pair <cite|liusvaara_edwards-curve_2017>.
-
-  <todo|SPEC: local node's keypair must be passed as part of the network
-  configuration.>
-
-  <\definition>
-    <strong|Peer Identity>, formally noted by <math|P<rsub|id>> is derived
-    from the node's public key as follows:
-
-    <todo|SPEC: How to derive <math|P<rsub|id>>> \ and uniquely identifies a
-    node on the network.
-  </definition>
-
-  Because the <math|P<rsub|id>> is derived from the node's public key,
-  running two or more instances of Polkadot network using the same network
-  key is contrary to the Polkadot protocol.
-
-  All network communications between nodes on the network use encryption
-  derived from both sides' keys.
-
-  <todo|SPEC: p2p key derivation>
-
-  <subsection|Discovery Mechanisms>
-
-  \ In order for a Polkadot node to join a peer-to-peer network, it has to
-  know a list of Polkadot nodes that already take part in the network. This
-  process of building such a list is referred to as <em|Discovery>. Each
-  element of this list is a pair consisting of the peer's node identities and
-  their addresses.\ 
-
-  <todo|SPEC: Node address>
-
-  \ Polkadot discovery is done through the following mechanisms:
-
-  <\itemize>
-    <item><em|Bootstrap nodes>: These are hard-coded node identities and
-    addresses passed alongside with the network configuration.
-
-    <item><em|mDNS>, performing a UDP broadcast on the local network. Nodes
-    that listen may respond with their identity as described in the mDNS
-    section of <cite|protocol_labs_libp2p_2019>. (Note: mDNS can be disabled
-    in the network configuration.)
-
-    <item><em|Kademlia random walk>. Once connected to a peer node, a
-    Polkadot node can perform a random Kademlia `FIND_NODE` requests for the
-    nodes <todo|which nodes?> to respond by propagating their view of the
-    network.
-  </itemize>
-
-  <subsection|Transport Protocol><label|sect_transport_protocol>
-
-  A Polkadot node can establish a connection with nodes in its peer list. All
-  the connections must always use encryption and multiplexing. While some
-  nodes' addresses (eg. addresses using `/quic`) already imply the encryption
-  and/or multiplexing to use, for others the \Pmultistream-select\Q protocol
-  is used in order to negotiate an encryption layer and/or a multiplexing
-  layer.
-
-  The following transport protocol is supported by a Polkadot node:
-
-  <\itemize>
-    <item><em|TCP/IP> for addresses of the form `/ip4/1.2.3.4/tcp/5`. Once
-    the TCP connection is open, an encryption and a multiplexing layers are
-    negotiated on top.
-
-    <item><em|WebSockets> for addresses of the form `/ip4/1.2.3.4/tcp/5/ws`.
-    A TC/IP connection is open and the WebSockets protocol is negotiated on
-    top. Communications then happen inside WebSockets data frames. Encryption
-    and multiplexing are additionally negotiated again inside this channel.
-
-    \ <item>DNS for addresses of the form `/dns4/example.com/tcp/5` or
-    `/dns4/example.com/tcp/5/ws`. A node's address can contain a domain name.
-  </itemize>
-
-  <subsubsection|Encryption>
-
-  \ The following encryption protocols from libp2p are supported by Polkadot
-  protocol:
-
-  <item><strong|Secio>: A TLS-1.2-like protocol but without certificates
-  <cite|protocol_labs_libp2p_2019>. Support for secio will likely to be
-  deprecated in the future.
-
-  <item><strong|Noise>: Noise is a framework for crypto protocols based on
-  the Diffie-Hellman key agreement <cite|perrin_noise_2018>. Support for
-  noise is experimental and details may change in the future.
-
-  <subsubsection|Multiplexing>\ 
-
-  The following multiplexing protocols are supported:
-
-  <\itemize>
-    <item><strong|Mplex>: Support for mplex will be deprecated in the future.
-
-    <item><strong|Yamux>.
-  </itemize>
-
-  <subsection|Substreams>
-
-  Once a connection has been established between two nodes and is able to use
-  multiplexing, substreams can be opened. When a substream is open, the
-  <em|multistream-select> protocol is used to negotiate which protocol to use
-  on that given substream.\ 
-
-  <subsubsection|Periodic Ephemeral Substreams>
-
-  A Polkadot Host node should open several substreams. In particular, it
-  should periodically open ephemeral substreams in order to:
-
-  <\itemize>
-    <item>ping the remote peer and check whether the connection is still
-    alive. Failure for the remote peer to reply leads to a disconnection.
-    This uses the libp2p <em|ping> protocol specified in
-    <cite|protocol_labs_libp2p_2019>.
-
-    <item>ask information from the remote. This is the <em|identity> protocol
-    specified in <cite|protocol_labs_libp2p_2019>.
-
-    <item>send Kademlia random walk queries. Each Kademlia query is done in a
-    new separate substreams. This uses the libp2p <em|Kademlia> protocol
-    specified in <cite|protocol_labs_libp2p_2019>.
-  </itemize>
-
-  <subsubsection|Polkadot Communication Substream><label|sect_polkadot_communication_substream>
-
-  For the purposes of communicating Polkadot messages, the dailer of the
-  connection opens a unique substream. Optionally, the node can keep a unique
-  substream alive for this purpose. The name of the protocol negotiated is
-  based on the <em|protocol ID> passed as part of the network configuration.
-  This protocol ID should be unique for each chain and prevents nodes from
-  different chains to connect to each other.
-
-  The structure of SCALE encoded messages sent over the unique Polkadot
-  communication substream is described in Appendix
-  <reference|sect-network-messages>.
-
-  Once the substream is open, the first step is an exchange of a <em|status>
-  message from both sides described in Section <reference|sect-msg-status>.
-
-  Communications within this substream include:
-
-  <\itemize>
-    <item>Syncing. Blocks are announced and requested from other nodes.
-
-    <item>Gossiping. Used by various subprotocols such as GRANDPA.
-
-    <item>Polkadot Network Specialization: <todo|spec this protocol for
-    polkadot>.
