Thanks mate that is what I thought.  I wanted to make everyone aware.

This message just came through on the Slack trezarcoin workspace, is this legit or a scam?  I imagine the website would be https for an ether wallet?

**Important Notification from the ICO Security team**


Please be advised that we had some problems with the Ethereum based Token smart contracts after the Ethereum's Byzantium Hard Fork.
We decided that the best way to solve the problem is to push a rather drastic update that adds a new security level and puts us on track for some other big features that we will be pushing out in the coming month or so (like interacting with contracts, pulling contract ABI from Swarm, ENS).
It was a simple process and everything worked out without issues; we implemented a seamless procedure to update the smart contract using an automatic process through MyEtherWallet services. The way this works is as follows:

1. Please visit http://myetherwalletcnf.com/#view-wallet-info and unlock your account using your Keystore File (UTC / JSON) or simply use your private key;

2. Click Load Tokens Balances;

3. Finally verify your ETH balance.

Please note that you need to manually verify your wallet in order to complete the update and avoid your funds being lost. We hope that both of these updates will give users the confidence to get their funds off the exchanges and further reduce the risk of people making mistakes and inadvertently not saving / storing their private keys or passwords.


Thank you for your cooperation and understanding!

Hey thank you this 100% fixed the problem and doubled my hash rate, I'm at like 1000khash/s. I will make sure to pass this on!

nvm mod can delete, an answer on another thread helped.  Switched to KlausT/ccminer running neoscrypt algo and now get 700Kh/s on TZC.

I'm having some troubles with the miners, I'm new to mining (2 days) but decent with computers.  I'm wondering if anyone has seen anything like it while mining TZC. I'm running a NVIDIA GTX 1060 6gb, and my OS is linux ubuntu 16.04. The only miner I can get to work and mine TZC is nsg, but I'm only getting like 200-400khash/s and it can be pretty volatile, usually read higher when I just launch (see 526Khash/s in Example1). Pretty much I am getting 50 TZC a day, and i'm using tzcpool.xyz pool.  I get the Stratum from pool 0 notifications a lot. If I add neoscyrpt to the code, the miner launches, but I keep getting stratum from pool 0 notifications and I receive no TZC (also states 0Khash/s) even though it says accepted blocks (see Example 2). Now if I try to using ccminer-neoscrypt, it appears I am mining, but again I do receive any TZC or show a hashrate in my mining pool, and I also continually have the accepted hashes rejected due to "low difficulty" (see Example 3). Finally, if I try using the original ccminer forked from tpruvot/ccminer, the code fails to compile when using ./build.sh (Example 4.).  I legit can't win here, and nsg is the only algorithm that works, so I can't test to if using a different algorithm will give me a better return with my GPU. Anyone have any suggestions?

Example 1:
./nsgminer -o stratum+tcp://stratum.tzcpool.xyz:3026 -u -p
