bug: uploading to the newly reset network many chunks have been carried over from the previous network

[happybeing]

I'm uploading lots of files that I previously uploaded, and after the recent reset most/all chunks are still there from the previous network.

[maqi]

chunks are still there from the previous network.

the nodes of previous network that owned by us will continue run for couple of days more to allow some statistic data to be collected.
or some other node owner's node forgot to reset and still stay with previous network.
In that case, if your client try to connect to previous network, then there is chance the connection will be established, and fetch some chunks back.
This itself shall not be considered as an issue.

However, if you mean your client is connected to new network, but can fetch some content that blongs to previous network, then that could be an issue.

Could you clarify the detail of this reported issue? thx

Yes, this is what I mean. I've seen this effect both with my client built for the new network, and with safe files upload using safe -V -> 0.95.0. @aatonnomicc also reported this when he was uploading BegBlag to the new network.

looks like there are some node owner did upgrade instead of reset for this time.
this will upgrade the node and allows it connected to new network meanwhile bring old records into new network

half the file already existed on the current network - hard to believe someone uploaded half of the chunks for me in advance

oh - stupid me ... @maqi already did diagnose it ... but somehow this still feels strange doesn't it? should this really be possible? ... that data was not paid for on this network ...

[rid-dim]

but @maqi you say this like it would be expected behavior ... isn't this highly problematic ...?

I could self encrypt my data and just start a specialized uploader node to upload it instead of paying for uploads… (or a uploader process that mimics a node for just enough seconds to do the uploads)
...or I could generate data, upload it to the network, shut my node down again - and repeat ...

Bringing data into the network for free opens the gates to gaming the system and for attacks ....?

[maqi]

it would be expected behavior

I don't mean it's an expected behaviour, just try to explain what happened :)

just start a specialized uploader node to upload it instead of paying for uploads

That node must to be close to the data generated.

Meanwhile, I have raised this as a concern and we are discussing the options to prevent that.
