[BUG] multiple new_signage_point spam, looks like malicious network attack

See original GitHub issue

Describe the bug Every ~10 seconds I should be getting a new signage point to test my plots against it. Usually it works fine. But sometimes I get tens (10x+) signage points at the same time with no apparent reason. It leads to extra load and lookup timeouts.

To Reproduce Steps to reproduce the behavior:

Enable log level DEBUG
Start farming
Notice sometimes signage points appear not one-per-10sec, but extra in bursts
Usually it will lead to multiple WARNINGs “Looking up qualities on … .plot took: 35.1394734382629395. This should be below 5 seconds to minimize risk of losing rewards.”, even though everything is fine with plots and disks

Expected behavior Signage points should come one at a time, not in multiple bursts.

Additional context I have created a Discussion post https://github.com/Chia-Network/chia-blockchain/discussions/4803 , investigated it from “maybe my drives are slow” into this current state “full node is sending bursts of signage points with no apparent reason”.

Currently it kind of looks like a malicious attack on network, maybe one or some of my peers or their peers are sending this. Maybe there’s something with distinguishing unique messages? (doesn’t look like it, since this messages of a burst batch trigger different “plots filter passed”, different plots).

Discussion mentioned got exactly zero replies, but now my investigation came far enough to warrant a bug. It looks not right at all, and it also looks like I have no way to influence it, multiple new_signage_point (queries to check my plots) just happen to come in bursts sometimes. I would think it’s signage points I’ve missed, but it’s not the case, timings do not match. It’s just some extra malicious signage points.

Please investigate and help. Most probably this is happening not just for me.

I also see this problem, and like you it causes a metric ton of proofs in a very short space of time, which also locks up new proofs from working properly.

We discussed it in this thread: https://github.com/Chia-Network/chia-blockchain/issues/1796#issuecomment-842004212

Anecdotal evidence suggests that the times of the problems are the same for more than just me, which suggests a central issue of some kind. I agree this could be a malicious attack vector.

Not seen a single comment from a developer on preventing this though, it could be worked around by caching all recent signage hashes and not attempting one it’s already done, that won’t prevent the signage spam, but it would prevent it from actually responding to it.

I also did see those spikes coming in my logs, couldn’t find any hard evidence for a specific issue so i just assumed it comes from forked chains -> where you get alot of signage points from the past seconds/minutes where a parallel chain reaches you. At least this is the conclusion i came to, might be wrong tho, so let’s hope it gets fixed or at least improved in the next patch 😃

Ps. It would be nice to know in the logs for which specific block the signage points are for(logging also the block hash for example)
