Team Guncoin is releasing a mandatory security patch upgrade - GUN Core V1.5.1. This is required due to a recent Bitcoin Core Team announcement of a vulnerability that was discovered last week in 0.16.0. As a result, Bitcoin Core is now at 0.16.3 and that includes the patch to eliminate the risk of the vulnerability to be exploited. https://bitcoincore.org/en/2018/09/20/notice/If you are running 1.5 and have already synced past the block with the illegal TX then you will need to start 1.5.1 with reindex=1 in your conf file, remember to remove that line before the next time you start. We have had Cryptopia to put GUN in Maintenance mode UNTIL the majority of the blockchain is on the new code. We will also update the seed nodes and the GUNCOINPOOL.com mining pool as well. We will be updating website and OP here shortly. https://github.com/guncoin/guncoin/releases/tag/v1.5.1All wallets have now been updated and are available on the website as well as from the GitHub link above. Please upgrade as soon as you can. Ok, that is one ugly bug, and a quick response!! Upgrade done.. Yes, it was and still is for all the Bitcoin Core based altcoins. We have completed and published all the updates - please pass the word to all. The Guncoinpool.com mining pools should be running the new code by Wednesday or Thursday. Once that is done and we see the blockchain results that we are expecting, we will have Cryptopia take us out of maintenance mode and do their update as well. Thanks for your support. We thank Bushstar and many others for VERY prompt action in getting this issue resolved quickly. |

Let me try and describe what happened to GUN on Cryptopia a few days ago and why we requested them to halt our trading and put GUN in Maintenance mode until further notice. Over the past week, GUN and many other coins who follow the Bitcoin Core technology were attacked when someone found a latent vulnerability in the BTC Core code and exploited it on several exchanges including Cryptopia. This was NOT a 51% attack, we have code to protect against that. It was a vulnerability exploit in the Bitcoin Core code that has existed since Bitcoin Core 0.14.0 (up to 0.16.0).
The attack created an illegal block, GUN V1.5 accepted and checkpointed it, GUN V1.4 rejected it. GUN V1.5 checkpointed the illegal chain. The attackers sent more than 400M in one illegal transaction, that's more coins than we have to date. Bitcoin Core 0.16.0 (GUN V1.5) thought there was nothing wrong with that unfortunately due to the exploited vulnerability. This bug had been present since Bitcoin Core 0.14.
So Bitcoin Core 0.16.3 was released to solve the problem and protect against further similar attacks. This is what we have included in GUN V1.5.1 which we highly recommend upgrading to immediately. That being said, it will take a LONG time to sync as it is checking each transaction - that takes a while.
As to what was lost by Cryptopia or our GUN traders who were in the middle of the mess, the outcome is still in question. Cryptopia froze BTC transfers, but not sure when and how much was saved. In reality, those transactions should be reversed within a few days. If the BTC was saved by Cryptopia, it will be returned. If not, you will get nothing as they have a disclaimer protecting themselves against a loss of this type. Likewise, since the code came from the Bitcoin Core community, there will be no liability on their part either - they published the update and we got it out within hours of discovering the issue.
Our Guncoinpool.com is being updated now as are a few other pools. Once this is done and we see clean blocks being mined, we will have Cryptopia start trading GUN. Again, we thank our programmers and team for getting the word out quickly and the fix in place as soon as possible.

They will have it fixed, when they get to it. We have given them the notice to upgrade the wallet, but they also have other coins. We are on the list. |

Cryptopia has acknowledged receiving our new code and will be updating us on their exchange as soon as they can. There are other alt coins that had the same problem and Guncoin is in the queue to get upgraded. |

Wait, so we need to resync the chain, since the current one has been exploited?
edit, using 1.15.1.0, it's not syncing, getting this
"ERROR: CSyncCheckpoint::CheckSignature() : verify signature failed"

That message is the old checkpoints still being passed around and rejected, that's the expected behavior. |

Ouch, just checked the cryptopia chart, looks like 25000000 were dumped on the 25th.

In reality no - that is one of the reasons for the recent code update. |

I understand that, these trades have been made though, or was there some kind of alarm triggered that halted everything? If so, props to cryptopia. Hope the culprits didn't run off with that big buy wall.

It is unclear to us as what if anything Cryptopia or users lost there. The new code prevents it from happening again and makes the coin that much stronger. |

We have over 60% of the community running GUN V1.5.1 now. We need the other 40% to upgrade their wallets from V1.4 or V1.5 as soon as possible. Please makes sure you re-index as required.

Im think that everyone who can see should fix this announcement in big red letters in the first message. So that immediately upon entering the first page where all the information above was this advertisement. Otherwise, even update 90% will not be achieved. |

in a week or so, you should simply release another update that refuses to connect with wallets older than v1.5 that 40% will never know to update because they will never read bitcointalk or other channels until things stop working for them. |
