A few weeks ago in #388, we changed the license for the mempool project
from MIT+CC to AGPLv3. This was generally met with very positive
feedback from the Bitcoin community. However, a few very large
enterprise organizations that love the mempool project are now no longer
able to use our code, since apparently some enterprise organizations
have an internal policy of not using AGPL licensed software.
Since the AGPLv3 license is compatible with the GPLv3 license in various
ways, adding the GPLv3 as an alternative second license for the project
seems like a reasonable way to retain most of the copyleft properties of
our current AGPLv3 license, while also keeping the community happy and
allowing them GPLv3 as another choice if they are prohibited from using
the AGPL internally.
Therefore, I propose to add GPLv3 as an alternative license for the
mempool open source project in this PR. If you are okay with this,
please ACK with "I hereby re-license my contributions to the mempool
open source project under both the GNU AGPLv3 and GPLv3 licenses"

The files contained in this source code repository are currently
released as "open source" under the terms of the [MIT license](https://opensource.org/licenses/MIT),
with the additional protections of the [Commons Clause License Condition v1](https://commonsclause.com/),
in order to restrict monetization of the mempool app, with the
intended result of mempool remaining free software (as in free
beer) for the Bitcoin community.
However, because of the Commons Clause being added to our license terms,
The Mempool Open Source Project cannot formally be considered as [Free
and open-source software (FOSS)](https://en.wikipedia.org/wiki/Free_and_open-source_software),
according to the generally accepted definition of ["What is free
software?"](https://www.gnu.org/philosophy/free-sw.en.html), and this
has drawn some criticism from the Bitcoin open source community.
Therefore, in order to make The Mempool Open Source Project truly FOSS,
I hereby propose to change our project's license to the [GNU Affero
General Public License v3](https://www.gnu.org/licenses/agpl-3.0.html),
which seems most suitable for a web application. While this won't keep
the mempool free as in free beer, it will keep mempool free as in free
speech, which is what actually matters.
Here is [the TL;DR of AGPLv3](https://tldrlegal.com/license/gnu-affero-general-public-license-v3-(agpl-3.0)):
> The AGPL license differs from the other GNU licenses in that it was
> built for network software. You can distribute modified versions if
> you keep track of the changes and the date you made them. As per usual
> with GNU licenses, you must license derivatives under AGPL. It
> provides the same restrictions and freedoms as the GPLv3 but with an
> additional clause which makes it so that source code must be
> distributed along with web publication. Since web sites and services
> are never distributed in the traditional sense, the AGPL is the GPL of
> the web.
Could all contributors to The Mempool Open Source Project please ACK
this PR? @softsimon @wiz @bguillaumat @TechMiX @junderw @andrerfneves
