Can confirm that portal client starts successfully with client start (tsx bin/cli.ts --enablePortal)

Added some logging to the startup within the client info logs

You can also view all the portal debug logs with the DEBUG=*Portal* environmental variable as well. Works like a charm

The failing test-all-browser test doesn't look like it has anything to do with the changes made in this PR, so I am reluctant to debug it from here...

Absolutely no relation. Vitest is broken in some obscure way.

Take note of changes in
f20434f
and
4fe901a

The --enablePortal option has been renamed to --enablePortalHistory to make room for network config options for other networks.

Also added are radius config options for each network. Keep in mind here that you are setting the exponent for the radius. meaning that a --portalHistoryRadius setting of 250 will result in a node radius of 2^250 -1

The radius for each network defaults to 0. A node with a 0 radius can retrieve and store data, but should not accept gossip. A max radius of 2^256-1 will accept ALL gossip.

Is there any value in keeping this open at this point?

[holgerd77]

I cannot judge. I would still be super eager to see Portal Network/Ultralight "in action" withint the client in whatever form, haven't gotten to this point yet. Cannot judge if this PR here is still an appropriate way to achieve this as some PoC or not.
