2019-09-27 12:54 - Nova Controlled Shutdown - Update on fees

Dear Nova Trader
The Board of Directors of the parent company has decided to set a new course for Nova and reshape the value 
offer into a new crypto trading experience.
This means that on Monday, October 7, trading on Nova Exchange will cease and close. At the same time the 
Nova API will be deactivated.
The Nova Exchange terms & conditions are terminated. New terms & conditions are announced and will come into 
effect automatically 30 days from today's date (September 26, 2019) 

The most important part of this message is this: 
1. This is purely a Business Decision.
2. There has been no hack. 
3. There has been no fraud. 
4. There has not been any wrongdoing of any kind whatsoever.
5. Nova Exchange will not assume responsibility for swaps or forks starting from today onwards.

这是继2017年 同域名交易所因网站运营权易手关闭后（后新管理层于2019年初重新上线交易所服务）第二次结束交易所服务。

据通告内容所说，结束交易所服务后，网站将转型成为 分享数字资产交易经验的内容类网站，继续在币圈贡献光和热。

重生不逢时啊，最初入圈的时候对这个交易所的印象还不错的，可惜了。

名称: Team Red Miner v0.5.3

参考社区网友反馈

Yeah, not the best summer algo. I’d clock down those Vega 64s a bit, doing ~2.9 MH/s at maybe 1200 cclk, 500 memclk. If you have the time, check the MTP_MINING.txt in the release package.

简单翻译就是 vega64和 1080ti性能相当，发热和功耗爆炸(核弹实至名归)，网友降频后算力稳定在 2.9M/s 左右。

性价比而言，天平略微向AMD倾斜。可以预见一大波AMD矿工正在向XZC涌来，XZC的未来行情仍是未知数。

祸兮福所倚，福兮祸所伏

CRDS节点升级后提示无法启动MN,

查看状态提示

root@mn:~/.credits# credits-cli masternode debug 
Not capable Masternode: Invalid protocol version

解决方法如下

  1. 确保节点端已经同步良好
root@mn:~/.credits# credits-cli mnsync status    
{
  "AssetID": 999,
  "AssetName": "MASTERNODE_SYNC_FINISHED",
  "Attempt": 0,
  "IsBlockchainSynced": true,
  "IsMasternodeListSynced": true,
  "IsWinnersListSynced": true,
  "IsSynced": true,
  "IsFailed": false
}
  1. 重新 genkey
root@mn:~/.credits# credits-cli masternode genkey
5iyTrgYL************2AXDm84YvDjSyLakZtNcDfmCihz
  1. 把得到的key 更新到vps钱包的 credits.conf 的 masternodeprivkey 及本地主控钱包的 masternode.conf 中。
  2. 重启本地及VPS钱包。
  3. 在本地主控钱包启动远端节点
root@mn:~/.credits# creditsd
Credits server starting
root@mn:~/.credits# credits-clWarning: Make sure to encrypt your wallet and delete all non-encrypted backups after you verified that wallet works!


root@mn:~/.credits# credits-cli masternode debug
Node just started, not yet activated

root@mn:~/.credits# credits-cli masternode debug
Not capable Masternode: Masternode not in Masternode list

root@mn:~/.credits# credits-cli masternode debug
Masternode successfully started

分别是VPS节点刚刚启动，节点同步完成，本地远程启动节点 后的三个状态
搞定

zcoin官方发推更新了他们的mtp ccminer, 考虑都我近半年一直在用 CryptoDredge 0.16 未曾更新，所以更新看看效果如何

测试设备
GTX 1070ti
24G DDR4 ECC 内存
驱动 nvidia CUDA 10.1 dev kit (由于ccminer仅支持10.1所以升级了)

不废话直接上结果

原数据

CryptoDredge v0.16.1

平均算力: 2.2M
TDP: 80%
温度: 73℃
fee: 2%
驱动要求： CUDA 9/10/10.1

现测试数据

CryptoDredge v0.20.1

链接 https://github.com/technobyl/CryptoDredge/releases

平均算力: 2.5M
TDP: 103%
温度: 78℃
fee: 2%
驱动要求： CUDA 9/10/**10.1**

mtp ccminer v1.1.19

链接 https://github.com/zcoinofficial/ccminer/releases

平均算力: 2.55M
TDP: 103%
温度: 78℃
fee: 0.25% (可以加 --no-donation 参数手动选择不给)
驱动要求：**10.1**

结论：性能差不多，但都是牺牲 温度提升 TDP 换取的 算力，自己取舍值不值得上。为了考虑寿命和安全，我决定继续跑在 80% TDP...
