I think it would benefit greatly the bitc= oin ecosystem to have in place few
lightning nodes running on mainnet,= against which folks can freely exercise
sophisticated cross-layers a= ttacks (e.g pinning) to demonstrate their feasibility
and severity, in= a plain fashion.

Indeed, this is one thing to execute an attack= on a private regtest or even
testnet, another on mainnet in real-worl= d conditions where the results can be
evaluated and discussed by a wid= e audience. I already call to put in place such
attack demonstration = experiences in the past (cf. in the context of the transaction
relay w= orkshop in 2021 [0]) and it would be more akin to the research standardsat major sec confs demanding for artifacts.

So if we have mor= e candidates, beyond Dave, who wish to put in place "free-to-pown"
lig= htning nodes, the basic setup could be the following for useful demo attack= s results:
- a full-node (e.g core or btcd)
- a ligtning node (e.= g core-lightning / ldk / lnd)
- running default mainnet setting for bo= th softwares

What else ?

It is more interesting to ru= n with default mainnet settings, as testnet / regtest
have usually myr= iads of specific behaviors and have all the real mempools congestion
c= ycles to deal with. As someone wishing to do attack demo, I'm fine pouring = the satoshis

From the viewpoint of a security researcher wishin= g to demonstrate the feasibility

be very useful. The= re is also the option to do that on private infra and come back with

My utmost pleasure to demonstrate some pinning attacks on nodes un= der real-world conditions.
