Antoine,

Perhaps it would be an idea to write a gist or some other public facing=20
page with what you need from volunteers, so it's kind of step by step?
Unlike Peter in this thread, I think most people would want/have to set up=
=20
new nodes to do this.

You have said: Current and default installs of Core/btcd + lnd/cln/ldk . I=
=20
know that e.g. Core has some pretty non-trivial choices but I guess we can=
=20
stick religiously to whatever is default.

But other details like:
amount in channels - does it matter?
How many channels? Channels of specific types (thinking e.g. unannounced)
Should volunteers have channels with each other? is there any aspect of=20
topology you require?
Network connectivity - I guess it's not important, but just in case worth=
=20
mentioning, e.g. should/should not use Tor etc.

Forgive me if some of the questions are ignorant, I have not paid a ton of=
=20
attention to the discussion around these attacks.

That also happens to be my Alice OpenTimestamps calendar, in production, so=
<br>
please don&#39;t do anything you expect to be CPU or RAM intensive. But if =
you<br>
accidentally take down the server, not the end of the world: OTS is a very<=
br>
redundant protocol and one calendar going down for a few hours is unlikely =
to<br>
do any harm.<br>
<br>
It has about $400 of outgoing capacity at the moment, and $2000 inbound. It=
<br>
gets hardly any donations at the moment, so if you manage to knock LND offl=
ine<br>
that&#39;s no big deal.<br>
<br>
That&#39;s not my money - it&#39;s donations to the OTS calendars that I ha=
ve no right<br>
to spend - so I&#39;ll ask you to pay for any expenses incurred by it durin=
g<br>
testing, and make a $100 net donation when you&#39;re done testing to make =
it<br>
worthwhile for the OTS community. If you manage to lose more than that on<b=
r>
justice transactions, I&#39;ll consider that a donation. :)<br>
