Could someone please tell me where I can get the latest version of the windows QT client?  The upgrade command just crashes the current wallet and i'm on v2.1.0 I believe I need something with a 7 in it. 

The one on the website is out of date

The twitter post about an upgrade didnt have any links for download, besides the link someone posted above which is still not the latest version.

- Ive been relying on my cryptocointalk PMs to keep me up to date - I apologize if I missed people PMing me from BTCTalk; but my contact@gridcoin.us email went down and I had no idea these emails were bouncing.  Ive been developing for the last 7 days til midnight, so I have not had time to visit BTCtalk on a regular basis.

- Chiz, Ive posted this numerous times, and Im tiring of posting the same info each time.  The Version on the gridcoin.us was NEVER out of date.  The issue is you have to uninstall gridcoin before reinstalling.  Id appreciate it if you could read all the posts instead of spreading slanderous information.

- If your upgrade fails, you either need to take ownership of your directory, or run it as admin first.  It works for EVERYONE ELSE.  That's a clear indication that you personally are not able to upgrade in your situation.

- Whomever is accusing me of not doing enough work on the website, it was rolled back after the DDOS attack, but the MSIs were not.

For anyone who wishes to Beta-Test the new CPU Miner feature scheduled to go live in 7 days:

(Note this is for TESTNET not production:)

CPU-Miner Release Notes:

[2.1.0.8]/95/9.8:

 

 

 

1.  Processor Cycle Conservation: Since Gridcoin is focused on conserving processor clock cycles for Boinc, the internal PoB miner will sleep when

    the last block was a CPU block.  You will see the Processor Utilization rise when your miner should be mining. 

    Do a getmininginfo and view PoB HashesPerSec to find if you are currently cpumining.

    Also, when all of your CPIDs have been exhausted, the miner will scale back utilization.

 

2.  All threads work on the same eligible project until one thread solves the block for that project, then gridcoin will calculate the next eligible project, you can view that in getmininginfo.

 

3.  The next viable project is selected by checking the chain for unsolved CPID+Project applicable to your instance within the dynamic lookback period (IE PoB Difficulty).

 

 

4.  Dynamic Difficulty:  Gridcoin divides the total network 'CPID:Projects' by 576 to arrive at a difficulty level.  This is equivalent to distinct project days.

    Example:  If we have 10 miners working on 50 projects, difficulty is .08, since 12* that amount could potentially solve blocks in one day.

    If we have 1000 miners working on 5000 projects, difficulty is 8.68, since it would take approximately 8.68 days for one individual to solve a project/block.

4b. The getmininginfo command will show PoB difficulty as calculated in days.  The higher the number the harder it is for PoB to solve the block.

    The calculation is based on total network project count divided by 576, giving amount of blocks that can be solved by CPUs in the lookback period.

5.  Execute "listitem network" to see total network projects.

6.  Look at getmininginfo "hashespersec" to see how many hashes your PoB miner is working on.  It will be very low when you are either waiting for a gpu to solve a block,

    or when all of your projects have been submitted/solved/in the chain.  It will be around 10k per sec when working at max speed (reference avg 8 core processor).

 

7.  Payment:  The Network Project RAC Avg over 14 days is divided by your submitted project RAC, and that percent is multipled * 150 to arrive at the block subsidy.

    Example:  If you submit a WCG project for 1500 RAC, and the net avg is 3000, the block reward is 75 grc.

 

8. Setting up the config file for testnet:  Note: This beta release ONLY works in testnet.  Some of these features "show up" in prod, but it is impossible to turn

   the miner on or generate a Block Type 2 in Prod, since we will all go live together at the same time.  Also, most of the config keys do work in the %appdata%\gridcoin\testnet\gridcoin.conf

   directory, however some keys only work from the %appdata%\gridcoin directory.

8b. Setting the config file for CPUMining:

    gridcoin.conf:

    cpumining=true

    threadlimit=4

    The cpumining key must be set, the threadlimit key is optional.  Threadlimit is the amount of threads gridcoin will use for cpumining. 

8c. Validity of CPIDs:  Later in the instructions you will find Gridcoins new CPID verification system does not require the GRC address on the public web site.  In order to

    implement that feature, we must hash your boinc e-mail address (This is never shared in any block, and is not shared outside of gridcoin).  However, you must provide the exact

    e-mail address in the config file in order for boinc to give us the validity of the CPID (which will save a lot of hassle for everyone regarding set up).  If you provide the

    wrong email address in your config, we will hash it, then hash that with the block solved, and we will compare that to the CPID solved, and find it to be INVALID, therefore you will not

    be paid, also 3rd party verifications will fail! 

    email=myemailaddress@mydomain.com

    You can always set up a new boinc account and transfer credits if you do not want to share it, but it must match boinc and will save a lot of time in the future.

8d. Copy these config settings in both gridcoin.conf and \testnet\gridcoin.conf to ensure the settings will be read when you launch testnet.

9.  To launch gridcoin in testnet mode: gridcoin-qt -testnet

10. Connecting to other nodes in testnet:  Testnet is hard to connect to unless we have a lot of nodes.  Add addnode=www.pgp.mx.  Also, turn on the gpu miner, as that seems to help.

     Once you are connected you can shut off the gpu miner if you prefer.

     I am bringing a testnet node online now to help start team testing.  Seed node www.pgp.mx (port 32759) listening on testnet.

 

11.  Corrupted block error: Since we have added many new fields, you may receive Corrupted Block Errors during boot.  This should only happen once.  The code will copy and reindex the blocks automatically.

12.  To see if the block you solved is a cpu block, we added "BlockType".  Do a getblockhash <blocknumber>, copy the hash to the clipboard, then do a getblock <hash>, and look for blocktype.

     For example, if the high block on testnet is 1150, do a :

     getblockhash 1150 <enter>

     Copy the hash to the clipboard

     getblock <blockhash>

     The block contains the submitted CPID, MultiAlgorithmSolution (IE Skein+Groestl+Cubehash+Scrypt), ProjectName, and RAC submitted for the project.

     To prove the CPUMiner submitted a valid CPUMined block, the "PobCalculatedHash" must match the Block "HashPoB", not have a CPID in the chain within the lookback period,

     have a valid cpid (Ie IsCPIDValid true), and the prior block must be a gpu block.

13.  To find the PoB difficulty, do a getmininginfo.

14.  To check the output of the credit check node system, execute :

listitem cpids

CPIDs that are valid and third party verified will have the Verified RAC value populated.

 

15.  New Automated Project Setup for CPU Miners:

     It is now possible to mine any official boinc project including WCG.  There is no specific set-up required, and now, you do not have to populate your Gridcoin wallet address in the

     web project as your username.  Gridcoin is now able to work with boincs internal public keypair to determine if the boinc CPID is authentic AND was submitted by the OWNER of the CPID.

     Another words, if a miner were to

     steal a previously solved CPID from the chain, it would not be possible to submit it as a block solution, and in addition, when a 3rd party makes an attempt to verify it, it will fail

     due to the publickeyhash+boinchash+cpidhash not matching the originators hash.  Additionally, if you try to copy the hash, that will fail since each block requires a new hash, and

     each cpid root of each block is new, so old hashes cannot be used to determine new hashes.

 

     During 3rd party credit check operation, the node will verify the validity of the cpid, the origination of the cpid, the hash of the root of the cpid, and then call out to the 3rd party

     check node (netsoft-online).  It will then memorize the RAC per CPID, and verify the RAC.  If our credit check nodes are down, gridcoin will attempt to verify the RAC via the blockchain.

     If that fails, Gridcoin will still stay up via the GPU miners, and CPU mining will fail *on certain projects* but the network will continue to operate.

     Projects that are found in the chain in history will succeed, in order to keep

     gridcoin running during widespread outages.

16.  Some of the things we will want to test:

16a. Verify rules are enforced: CPUMiner cannot mine two blocks in a row, cpuminer cannot mine blocks already in chain within lookback, diff rises on cpuminer side, gpumining is

 regression tested, Payment amounts are verified, 3rd party nodes work as planned, read debug file to verify result codes are equivalent to expected codes, etc.

 

17. Backwards Compatibility:  Blocks and Tx are backwards compatible.  Test the ability to close out of testnet, and resume mining in Prod with the same beta version.

 

18.  Download:

Regarding Linux & Mac:

The new cpuminer version that is coming out in 7 days is almost completely cross platform with native Linux/Mac compatibility.  Im working hard to remove windows features and make the new versions cross compilable.

In the mean time, you can download the windows MSI and run it on Linux in wine with "wine gridcoin.msi", after it installs, run the shortcut, and you should be able to mine with that version.

Excellent, great to hear man! : D

On another note, anyone who is interested in beta testing gridcoin and participating in the test network should visit this thread on how to connect to the testnet & how to report issues:

Thanks for the update, but as I mentioned I had uninstalled it and deleted the folder before the last time I downloaded it.  I was able to get a working copy from someone else here on the forums.

Still have a transaction for 9827 gridcoins sent from the exchange that never confirmed.  Do you have any idea how we could track down if they were from a fork or whatnot?  Did you have any information on who was the network attacker?  It's actually worth like .2BTC and I don't really want to be at fault for covering it so it would be nice to find out what was up with those coins.

Thanks

Looking for the best exchange? -> https://bittrex.com

Lots more miners will be able to join once they can run natively on linux.

are you an update your primary website to make it seem as if this coin is still active? Come on guys.. If you need some help ask and the community and/or I will help out. The coin has a USP. I just worry about the marketing, website and if the team is truly committed to making grid coin a success.. Your feedback would be greatly appreciated!

I double this question, Twitter account seems dead, and atm the dev speed is as important as keeping website fresh, and keep visiting here (by far the most visited forum for cryptos).

Just my suggestion, keep up the good work guys Smiley

I double this question, Twitter account is basically dead, and atm the dev speed is as important as keeping website fresh, keep visiting here (by far the most visited forum for cryptos), and keep posting on Twitter.

Even once you'll develop all, you'll get no result if you did not tease before, pushed marketing, count downs to release day, creating the buzz.

I love the idea of this coin but original dev team should be as preset in developing as much in marketing even if that means slowing down developing a bit. Loads of ppl know about GRC, many doubt about because of the silence on Twitter.

Just my suggestion, keep up the good work guys but try putting as much of it on marketing Smiley
What's important is getting it working, and you're looking completely over the fact that this could move all of the gpu miners to boinc under gridcoin and greatly help the development of cures for diseases etc.
Sure the website is a bit lacking, but it's on the to do list. The twitter feed isn't dead, it regularly posts updates.
And this coin is still very young, only like 5% of the coins have been mined thus far.

Hi,

Tying to mine this with a 6 GPU rig...Do I have to use the Mining Module? Do i need 1 instance of cgminer for each GPU?
BOINK is open but im unsure if its supposed to be SUSPENDED or not?

Im still confused, can someone help?

Thanks

Thanks alot for not answering any of my doubts :/
That tutorial does not answer any of them.
Is it mandatory to start cgminer through Mining Module?
Do I have to use 1 instance per GPU?

Why do I get a blank page on the GuiMiner tab?

It is not mandatory to use the built in miner. Just start cgminer like you start it with other coins. If you use the built in then you need to make intance for each card but like I said it's not mandatory.
