-------------------------
Hello from Bitcoin Gold Organization, here is an RC of the updated core wallet for the hard fork.

https://github.com/BTCGPU/BTCGPU/releases/tag/v0.15.1-rc1

Code:

This is a Mandatory Upgrade. Everyone must upgrade your full node to v0.15.1

Changes:
   Equihash-BTG (144,5)
   LWMA difficulty adjustment algorithm
   Mainnet hardfork height: 536200
   Testnet-v3 compatible

Upgrade guide: #331

This is the RC1 version for v0.15.1. The current version is produced from Gitian build phase 1. 
The release are verifiable, reproducible, and signed. 
However the Windows and macOS binaries are not code-signed (for shutting up the complains from the OS).

When we receive enough Gitian signatures (>3) we will continue to finish the full build process.

The checksums of the binaries are signed by h4x3rotab (PGP: 0x38EE12EB597B4FC0). 
Please verify the checksum and the PGP signature before using.

Here is additional info:

Great news! I was starting to worry about the coin, but now it's gonna be okay. I'm hoping for this fork result. These constant hacker attacks were very angry, the network was down and my coins could not be used. Also, the price fell very much. Does this mean that all coins using this algorithm now require an update? I think so.

[Admkng5]

Why new theme?
But old fork was with big prenmine, trojan in official wallet and hidden fee on the pool. Is this fork also made to make a huge premine on new algorithm?

[kaigeta]

The forks are coming, the forks are coming!

[Admkng5]

Be careful with this fork, maybe viruses in this programms.

[BitcoinGoldHQ]

Please share feedback and bug reports here, on our discord or telegrams, thank you!

The code is signed with my PGP key. The precompiled binaries are also signed with my PGP key. I'm legally responsible if the wallet contains any malware.

Suprnova is updated and will support that fork on a new port

Thank you!

Well friend, thanks for letting us know, but I'm not experiencing any inconvenience in using

You know, viruses was in early versions of your wallet.
What can you say about huge premine? About hidden fee in your pool from start? And users mined more then day after start and got nothing. Be careful with it.

You really know a lot about BTG's history! Looks like misunderstanding of BTG is very common. But we know that it's never too late for us to realize and begin to fix it

1. Our GitHub account was once hacked and the released binaries were replaced by a hacker. It doesn't come with any typical virus but added a very clever backdoor. We have never seen this kind of attack before. Fortunately we have finally solved the problem before the coins are hacked. Here's the analysis:
https://github.com/BTCGPU/BTCGPU/wiki/Replaced-Windows-Wallet-Problem-Analysis-(Nov-26th)
And the announcement after the accident:
https://medium.com/@btcgpu/vulnerable-wallets-and-the-suspicious-file-82cae0c48a48

2. The community endowment (or, premine as you said) is 0.5% of the total supply. We don't know any other altcoin with this tiny amount of premine. The endowment is mined by the miners by their willing. All the endowment are in 4-of-6 multisig with time-lock to ensure it won't be dump by any team member. The use of the endowment is totally for the development and community, as described in our FAQ (currently our website is under attack but as soon as it's recovered I will put the link here).

3. In principle, the pool z-nomp was developed by one of our core dev (Martin) and it hasn't once been included as a part of the official BTG project. It's his right to include any fee in the software (just as miners, but the pool is an opensource project). Some of the pool ops who had read the code have removed the fee and some had kept the fee. However one operator didn't read the code and complained on social medias. Then Martin admitted it's his fault for not addressing the fee everywhere in the documentation. And finally he returned all the fee to that pool, and donated the remaining to charities.

4. On the first day of the launch the partnered pool "pool.gold" has encountered some problems which caused it in an incorrect chain. Technically it was not a chain split because pool.gold itself produced a wrong chain. It ends up the pool lost some blocks. The pool finally 100% refunded all the miners according to the accepted shares in the database.

Hope you are happy with my answers.

[Admkng5]

Why need to change the algorithm?

Why need to change the algorithm?

Hello, the reason for this decision was because of Bitmain's release of the Antminer Z9 mini (Equihash ASIC). BTG's vision has always been ASIC resistance so there was no discussion to be had about this, we had to act.

Our new algorithm is a collaborative effort, we are using a variant of Equihash that is quite a bit more memory hard (2.5GB per thread), this should be sufficient to invalidate this batch shipment.

Cheers.

You don't need to do anything. Just avoid sending or receiving BTG near the fork height.

Hope you are happy with my answers.

so:

1. 51% attack and 388k coins stolen, being dumped on Bitfinex now;
2. what about that February Xapo coins that are being dumped on exchanges and not via OTC? How many coins do they have? like 700k I guess?

You are down 95% from ATH. It is a well known fact that even small Bitmain GPU farm can make 51% attack again on your chain. Nice exit scam tho. Selling ATH like Charlie Lee did ) I think this is an asian thing.
