Ok, so I can just rent a standard Blake256 rig on launchday, right? 8 or 14, who cares anyway?

Please give me some tips. How do I mine at launch day. I'm getting a bit frustrated and i'm kinda drooling all over my fucking keyboard of excitement and anger.

You can't rent to mine decred. There are no rentals that would support decred mining.

Nice Java GUI wallet beta released by SG-O, for those that don't like to work in command line
https://forum.decred.org/threads/java-gui-wallet.382/

Some of features implemented are:
- Show balance
- Show a certain number of transactions
- Lock and unlock wallet
- Sending Decreds to an address

This version has only been tested on Windows 7
Tanks to SG-O for the effort, users community rocks and i'm already loving this coin 

Pretty cool effort. I like the idea, especially when I could use it on any operating system that supports Java (which makes it kinda like portable) Decred just keeps on giving and giving. I can't wait for the mainnet launch.

Everyone using my builds should update to the latest one here for Win64:

https://ottrbutt.com/miner/downloads/decred-cgminer/wolf-decred-cgminer-02042016-win64.zip.sig
These are based off of the official Decred CGMiner GitHub sources found at https://github.com/decred/cgminer - branch 3.7, commit c172a7a62455fae62afdc7995021f5c046aab9d7 with small modifications to get it to build with my set of Win64 tools. As before, it should require no DLLs other than what ships with Windows to function. Failure to upgrade may result in rejected/duplicate shares when pool mining, and/or other bugs.

Thanks!

Nice, a pool is already up. Rented some hashes to test but pool (suprnova) doesn't seem to work. Probably because it's some new algo, right? It's hard for a pool to implement new features, but i'm sure you will get it done before launch.

You cannot rent hashes for this algo yet.

Suprnova is working perfectly fine

EDIT: OK NVM this from Wolf now works perfect - no rejects at all! -> https://ottrbutt.com/miner/downloads/decred-cgminer/wolf-decred-cgminer-02042016-win64.zip

OCminer any ideas why I have 24% reject ratio of shares after running 30mins? I am using Wolf compiled win64 cgminer from your source code... Is this working perfectly fine? I am pretty sure I will get banned from your pool because of so many rejected shares no?

me too had so many shares rejected while testing a pool with that same miner in 7950 card, not sure whats wrong.

[DanWalker]

yes, me too just rejects and (time-to-new)

[thefix]

Very interesting project, unfortunate that Nvidia miners are not getting the same love as AMD

Do we need to crowd fund to get something valid released?


Maybe we just do not have enough Nvidia miners to Justify our existence.

Really, you're not being as picked on as it seems - CUDA is great when it comes to more complex algos, or algos that can benefit from Nvidia-specific optimizations that the compiler is unable to find by itself, but this is not the case for Decred. Really, you're talking about a minor bump I would guess, at most. The algo is dead simple - I've made the miner a few percent faster on AMD - but we're talking single digit percentages... and low digits. The Nvidia OpenCL compiler would really have a hard time fucking it up.

I appreciate the clear explanation

The small percentage gain with AMD will even out with lower power consumption on Nvidia cards.

If AMD gets the power consumption down this year on its new line it may be time to Jump ship or at least diversify my rigs

[ocminer]

Be sure to use the latest version of cgminer - it's tagged 0.0.2 from decred official or compile directly from github:

https://github.com/decred/cgminer

I'm unsure on which version Wolf's compile is based on.

Earlier versions had two (severe) errors:

roll-work was broken - this means the ntime of the work done was incremented at the wrong end of the hex string, the years where incremented, not the seconds. The work was done for shares in the year 2525 or somewhere then - which of course then are rejected by the daemon. So the pool rejects those shares (time-too-new). This is or at least should be fixed in the latest version.

duplicate shares - those are also fixed in the latest version.


If you still get those errors with the latest versions of the miners, let me know with the workername and i'll check in the logs what you've submitted.
