Hi @PascalCoin,

I figured out, I missed some Blocks

here

and here

Got the same behavior in Version 1.4.3 ... mining on the wrong block

as you can see here.

Sometimes I even thought, Supernova Pool was one the wrong block, according 2 dashboard.

When I take a closer look at the Payload/Operations of some blocks, and their time,
my guess is sombody (powerfull) tries 2 freak the System.

Many Pascalcoin clones started as I see. Pascal Lite, Turbo pascalcoin... Undecided

I had to stop mining on Nanopoool because it takes too much time for it to show the miner stats, so I think I am mining to nowhere. In the case of Suprnova, the cpu load for SGIminer is too high, so, at this time I am not able to mine in any pool.

Any chance to mine on Suprnova using other miner?

sgminer-5.5.0-pascal-1-windows-amd64

Hi, thank you for your response. Is that a command to be used with sgminer?

Command: sgminer.exe -k pascal -o stratum+tcp://pasc.suprnova.cc:5279 -u Weblogin.Worker -p WorkerPassword -I 21 -w 64 -g2

my cpu is running at no load

Edit: I have used the Sgminer already, but it demands too much from the CPU. It takes CPU'S activity to 100.

these are the code changes nanopool made: https://github.com/nanopool/PascalCoin/commit/f6949c4d16b43b4ffc567c4ed5bc67b48d0ac65c

I see them trying to mess with timestamps and adding an office. Is that not clear enough?

has anyone figured out yet how to use sgminer to solo mine ?

i'm sure ocminer will have a solution pretty soon.

let's see how things goes.

btw the link works now, on latest wallet 1.4.3.

** PascalCoin miner ** Version: BETA 0.3 FOR SUPRNOVA TESTING ONLY

thats the latest miner that comes with the latest wallet. so it's meant only for suprnova or can we use it to solo ?

Also to everyone shitting on Pascal Lite:

This coin launch uncovered a major flaw in Pascalcoin, you should be happy that it wasn't abused in a serious way on Pascalcoin and that it was quickly fixed. From my understanding one also needs way less than 51% to perform a 51% attack when abusing this flaw.

Instead you go: "Hurr durr it's a fake!11!" Roll Eyes

Looks like ocminer discovered the exploit and he was getting attacked.

Sounds like it was one or more parties trying to game the system, not Suprnova.

The dev may know the answer, but I'm siding with Suprnova.

The exploit was found when Pascal Lite launched, at least two miners got lots of blocks with this technique and caused many miners to not being able to submit their valid blocks.

That makes sense, thanks for speaking up.

Suprnova 4 hours running with no block. Who's really the bastard here? Nanopool?

Failure to suprnova
Supernova 59216, blockchain 59236

who are you,the miner abc_ is my solo rigs,now i change the name

You're right, this is a coincidence

Looks like someone is trying to make abc_ as the culprit here.

I saw blocks being found by nanopool and by ABC1. That's what I'm saying. Nice exploit guys!

You would say that because you were able to find some blocks..are you coordinating with nanopool?

There seems to be an attack going on ... I was ddosed and while I was ddosed I noticed blocks with "high" timestamps which subsequently reject my blocks with the correct time:

02-02-2017 10:27:10.151 TID:E5496700 [Error] Sending Error JSON RPC id () : Error: Invalid timestamp (New timestamp:1486027668 last timestamp (58999):1486027790) payload:SUPRNOVAROXXXXXXXXXXXXHXpLc/------ timestamp:1486027668 nonce:1303498590

I'm investigating what is actually going on exactly...

Frontend will be fine in a few moments, the DDoS ended.

OK, there are several nodes sending valid blocks with higher timestamps:

02-02-2017 10:45:18.259 TID:F0977700 [Error] Disconecting 89.249.254.45:50962 > Invalid remote timestamp. Difference:227 > 180

Thus making my blocks "invalid" through to too "old" time even though my clock is correct:

02-02-2017 10:44:59.041 TID:F0977700 [Error] Invalid new block 59002: Invalid timestamp (New timestamp:1486028696 last timestamp (59001):1486028710)
02-02-2017 10:44:59.041 TID:F0977700 [Error] Sending Error JSON RPC id () : Error: Invalid timestamp (New timestamp:1486028696 last timestamp (59001):1486028710) payload:SUPRNOVAROXXXXXXXXXXXXRkmq4------- timestamp:1486028696 nonce:3038414114

What those guys exploit is an old bug which was fixed in bitcoin years ago. They send their blocks with a maximum "drift" ahead ..

Example:
It's now 11:30:00 and blockchain is at height 59000
Max Drift is 30 seconds

So they say they solved Block 59001 at 11:30:30 even though it's just 11:30:00 and now my pool finds the next block as 11:30:20 which is BEFORE 11:30:30 so the blockchain rejects the block and says "Nope, your clock is wrong (even though my clock is right!) and I reject your block because the block before was discovered later"...

We need the dev here to fix that..
