Copyright Infringement of HUSH code

This file exists to document the copyright infringement of HUSH code as clearly as possible with as much supporting info as possible, so people can decide for themselves. Any project that infringes on "The Hush Developers" copyright will be listed here. Currently there is one project that severely infringes the copyright of Hush code, which is Pirate.

Copyright infringement is when one project takes code from another project, and maliciously or accidentally changes copyright information and/or mixes code of incompatible copyrights together. In the case of HUSH, our code is GNU Public License Version 3 (GPLv3), which means projects that use non-GPL code cannot (legally) take our code and add it to their project, unless they:

* Change their copyright to GPLv3 (or a higher version)
* Add copyright disclaimers from "The Hush Developers"

z_getbalances RPC

Hush wrote a new RPC which does not exist in any other cryptocoin called z_getbalances first created on April 13th 2021 in commit 52e14828c8 then less than a month later the same exact RPC name, with same functionality was added in Pirate commit be114569ec . It adds a new optional argument and is a derived work:

https://github.com/PirateNetwork/pirate/blob/master/src/wallet/rpcwallet.cpp#L4157

hush-cli was renamed pirate-cli

Very interestingly, in 412f5a2961 it can be seen that the hush-cli script was renamed pirate-cli, and the Hush copyright line was removed and replaced with a Pirate copyright that says "no rights reserved" :

#!/bin/bash
-# Copyright (c) 2019 Hush developers
+# Copyright (c) 2019 PirateChain - no rights reserved

# set working directory to the location of this script
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
cd $DIR

-NAME=HUSH3
+NAME=PIRATE
CLI=${KOMODOCLI:-./komodo-cli}
$CLI -ac_name=$NAME "$@"

This file no longer exists in their master branch, but is a good example of Pirate blatantly infringing on Hush code copyright.

TLS Code

Pirate seems to have copied huge sections of the TLS code from Hush, including entire files and detailed code comments in certain functions, while also not adding our Copyright disclaimer to their files. Since Pirate is MIT and Hush is GPLv3, mixing this code is incompatible.

For instance: https://github.com/hushmirror/hush3/blob/dev/src/hush/tlsenums.h was created in commit a21bf40510 on Oct 31st 2021 but https://github.com/hushmirror/hush3/blob/dev/src/hush/tlsenums.h was created on Sep 29th 2020 in commit 62f67821ec

The files are almost exactly the same, except Hush Copyright lines have been removed, the namespace "hush" was changed to "tls" and whitespace has been added. The exact ordering of elements and exact names of variables is exactly the same.

Another fact is that all the filenames in https://github.com/PirateNetwork/pirate/tree/master/src/tls are exactly the same as the filenames in https://github.com/hushmirror/hush3/tree/dev/src/hush yet the Hush files were created over a year prior.

Additionally the function threadSocketHandler at https://github.com/PirateNetwork/pirate/blob/master/src/tls/tlsmanager.cpp#L347 is almost exactly the same. The differences are because Hush uses WolfSSL where Pirate uses OpenSSL and logging to a different log category ("net" vs "tls") .

The -tls CLI option and -tls=only argument was added in commit 62f67821ec on Sep 29th 2020 and then appears over a year later in Pirate source code in commit a21bf40510

Additionally, Hush added the field tls_connections to two RPCs: getinfo and getnetworkinfo and Pirate took this code, and turned the oneliner to a for loop to make it look different, yet it is still a derived work:

pirate/src/rpc/net.cpp
515:            "  \"tls_connections\": xxxxx,              (numeric) the number of TLS connections\n"
557:    obj.push_back(Pair("tls_connections", sslNode));

pirate/src/rpc/misc.cpp
212:            "  \"tls_connections\": xxxxx,   (numeric) the number of TLS connections\n"
302:    obj.push_back(Pair("tls_connections", sslNode));

hush3/src/rpc/net.cpp
506:            "  \"tls_connections\": xxxxx,              (numeric) the number of TLS connections\n"
541:    obj.push_back(Pair("tls_connections", (int)std::count_if(vNodes.begin(), vNodes.end(), [](CNode* n) {return n->ssl != NULL;})));

hush3/src/rpc/misc.cpp
219:            "  \"tls_connections\": xxxxx,   (numeric) the number of encrypted TLS (SSL) connections\n"
293:    obj.push_back(Pair("tls_connections", (int)std::count_if(vNodes.begin(), vNodes.end(), [](CNode* n) {return n->ssl != NULL;})));

You can also notice they exactly copied the documentation of each RPC, with no changes.

In the file src/net.h you can see that Pirate copied the exact variable names of the TLS context objects:

pirate/src/net.h 
extern SSL_CTX *tls_ctx_server;
extern SSL_CTX *tls_ctx_client;

/hush3/src/net.h 
extern SSL_CTX *tls_ctx_server;
extern SSL_CTX *tls_ctx_client;

Additionally, these two objects were added at exactly the same place in the file, between the strSubVersion and LocalServiceInfo struct.
