📝 Original message:Hi,

As far as I understand your answer is "let's try to use what exists",
this is not what I am proposing and not the Tor network, no "standard"
exit nodes, different hidden services, decentralized anonymizer network
unlike the Tor network, nodes are anonymizing themselves

Comments below, please let me know what is unclear in the description of
the project so I can modify it because all the time I get the impression
that it is mixed with the Tor network while it just has a very little to
do with it, and I don't get that the simple principle of communicating
between nodes using the Tor protocol without RDV points is never considered

Regards,

And centralized structure, limited set of nodes to make it short, for
some (or a lot) misbehaving, not designed for bitcoin, nothing prevents
bitcoin from operating its own anonymizer system, which I am proposing

Good to a certain extent... if you want to hide that you are operating a
bitcoin node you can use RDV points (ie hidden services) but if you
don't care you just connect anonymized circuits between bitcoin nodes,
this is more "direct" and does not exist in the Tor network, this
includes light clients that can act as relays also

There are plenty of Tor-to-Tor issues, not theoretical but in the real
world, "Tor-to-clearnet" can be done outside of the Tor network, ie the
bitcoin network

Probably, again I am not proposing a remake of the Tor network, I don't
see the use for a miner to hide (neither for a bitcoin node to use RDV
points), but they can be part of the global anonymized system, please
see below

Yes but one full node should be able to do this alone, ie implement both
interfaces, like miners and everybody in fact (or Peersm bridges with
bittorrent if you look at the history of the project)

Please see the convergence link, it's not based on the assumption that
"the more you are the better you can hide and the lesser you can get
attacked", this does not work at all, it's based on the assumption that
even with a reduced set of peers it becomes very difficult to know who
is doing what and whom is talking to whom, the concept of
exiting/bridging to clearnet(s) is not clearly detailed in this version
but appears on the drawings
