 Senders not supporting payjoin will just ignore the <code>pj=</code> parameter and proceed to typical address-based transaction flows. <code>req-pj=</code> may be used to compel payjoin. 
 
-Receivers may choose to support version 1 payloads. Version 2 payjoin URIs should enable <code>pjos=0</code> so that these v1 senders disable output substitution since the v1 messages are neither encrypted nor authenticated, putting them at risk for man-in-the-middle attacks otherwise. The relay protocol should carry on as normal, responding to `/receive` get requests instead with this version 1 request as BHTTP in an OHTTP response. The receiver should POST version 1 Payjoin PSBTs to `/receive` to respond to these version 1 senders within 30 seconds to respond to the sender's request.

 ==Reference implementation==
 
-An early proof of concept draft reference implementation can be found at https://github.com/payjoin/rust-payjoin/pull/78. It implements an asynchronous payment flow using WebSockets using PSBTv1 without encryption. Another reference can be found at https://github.com/payjoin/rust-payjoin/pull/21 which uses HTTP long polling for transport and Noise NNpsk0 for crypto. Recently, I've come to realize the rationale for WebTransport, PSBTv2, and Noise IK substitutions and am working on an implementation including this exact specification, but wanted to get early feedback on this design in the spirit of BIP 2.
+An production reference implementation client can be found at https://crates.io/crates/payjoin-cli/0.0.2-alpha. Source code for the clients, directory server, and development kit may be found here: https://github.com/payjoin/rust-payjoin. Source code for Oblivous HTTP relays may be found here https://github.com/payjoin/ohttp-relay. The reference implementation implements an asynchronous payment flow using HTTP using PSBTv1 with encryption and Oblivious HTTP and may be configured to the following independent production relays:
+
+A payjoin directory server is run by the Payjoin Dev Kit team on https://payjo.in.
+
+Independent Oblivious HTTP relays are run by Obscura VPN at https://ohttp-relay.obscuravpn.io/payjoin and by BOB Spaces at https://pj.bobspacebkk.com.
