@Josh has just pointed out an error in a PR I have raised for his script. I just want a running network to test the workaround against for a few hours yet.
Looks like we are going to need sudo after all 
Not a biggie, I’d just prefer to avoid it if possible.

Well, it’s running! But how useful it is I don’t know because it seems you can’t upload anything. I’m getting:-

So it looks like sending the tokens is failing because that counts as being a record in itself!
But if what you are testing is just to do with node functionality or connectivity I suppose it might do the job.
I won’t shut my nodes down until everyone else has!

I’ll leave mine as well lol see what happens although last time I checked in a few were dieing die to running out of memory

My node has 2015 records and is seems it’s not getting any more. I’ll leave it running anyway, at least until tomorrow.

Thank you to all the team who made this RewardNet possible, thank you to all who kept their nodes running (alamoNet) when all seemed lost.
I have made a fix in one place and found a problem in another but I no longer need a running network to continue.
So thanks again to you all, I can hopefully sort it from here.
the setup script reports pandas was installed OK but when you actually need to use it, there is a problem - likely due to me not using venv correctly, I think.

Traceback (most recent call last):

@Josh kindly sent me a Dell/Wyse miniPC so I will use that to try to install the Rewards_plotting package on and test with a saved resources.log
Which is what I should have done all along instead of asking you lot to keep nodes running – sorry…
Avanti!!!

There a lot of potential ways to do it. Both with or without a queue as you suggest. However, the simplest way to approximate Mitchell’s Best Candidate Algorithm (see below) may be to use a queue and select the node that is farthest in xor from the close group. This is also referred to as “blue noise” sampling instead of purely random “white noise” sampling.

Hope to get it on the next testnet, as this one seems to be winding down 
.
Definitely read through all the posts and updates on this RewardNet test run!
Loving the overall progress, and feedback between Maidsafe and the community!
Keep up the good work everyone!

Haha, it is going to be a few days as we get in a wee bit more work that we’ll be testing out.
@Toivo @storage_guy @Southside et al! Thanks for trying to carry the torch! 
I was wondering when we’d see that .
(It probably is very unlikely to survive though when maidsafe has such a high percentage of nodes… down the line we’ll have a look at a smoother wind down, I suspect. That’ll be easier once we have some more of the metrics work in).

Though if we shrink it in a controlled way down to…hmm… 10 nodes, and accept the data loss, maybe we can re-grow it back up, and start uploading again.

I’ll be able to add quite a few nodes once they get hole punching worked in. Probably several hundred, at least.

Adding to @dirvine’s response, so the attack described by Vitalik isn’t relevant for the current safe network implementation but sybil remains a relevant threat and how can that be defended against? Well, the sybil issue relevant to safe network actually affects ethereum and ipfs too. And there’s a lot of work being advanced to guard against it, some already being implemented into libp2p (which ethereum, ipfs, filecoin, etc. all rely on). Here’s an example: https://arxiv.org/pdf/2307.12212.pdf. So through libp2p, safe network inherits / will inherit those sybil defense mechanisms being evolved by the field.

Nice find @Bogard I have been working on the side with a few more ideas, but this paper is really encouraging and avoids us having to persuade libp2p to take on our sybil defence mechanisms. Best of all, we all get to share the anti sybil attack work here. Great news all round

My node shut down in the morning by accident 
Are anyone else still connected?
iv still got some nodes trying to do something this one is still alive from my nodes log but isent one of mine

OOps! I forgot I’d said I would keep my nodes running and stopped them all!
But I’ve started up 1 just to see if it’s still alive. I used:-
export SAFE_PEERS="/ip4/38.102.87.158/tcp/4717/p2p/12D3KooWDHJGVRrXJsUna8aZ7tTPfkhSVbpBnbfMkB97TzozjYoh"
that @neik found worked to start mine up.
So here is mine:-
export export SAFE_PEERS="/ip4/54.88.136.70/tcp/12000/p2p/12D3KooWGM9BE31WuvVyUkdvT7YVykXZg7chQwNtz16dHvPztEGA"
and I’ll join this futile endeavour and leave it up until the next testnet.
My node got the max 2048 records for 669MB which suggests there is a large deficit in resilience the system is trying to rebuild.
I’m showing 84 nodes connected to this one. Is that the total size of the network? It’s not looking good considering that there were around 380 when the network was officially up.
Oh go on then, I’ll start up an Instance with 50 nodes. In for a penny, in for a pound. Let’s face it, I spend more on chemical entertainments per day than this will cost. I begrudge giving Bezos any more money though. Maybe now he can do us all a favour and buy some larger cycling shorts.

I don’t know what you mean about that, and I’m pretty sure I don’t want to know (no pics, thank you). If only tech moguls would invest as much in solving the midlife crisis as they do in trying to live forever I feel we’d be in a better place.
I tried to upload some chunks.
Sadly Not enough store cost quotes returned from the network to ensure a valid fee is paid.

If anyone wants to have a go at plotting their rewards distribution over multiple nodes duringthe next test @Southside has done a great job of simplifying the process. 
It is also possible that if anyone wants to log their rewards, we could pool them together and generate a single chart to get a bigger picture.
