Finally we got a good block explorer for GRC!

Block Explorer is now up and running!

GRC was number 1 several days ago on the mintpal voting. It had over 100,000 votes.  Now it is number 12 with 38,000 votes? What happened?

Hi,

it was GRS - GroestlCoin and it got listed.

are you sure was GRC and not a coin with a similar name like GDC?

Yeah, as someone who votes almost everyday, I can confirm we did not get to 100000.

PS. don't forget to also vote on Cryptsy.

If we can add our own custom Boinc projects like 3D rendering that can be very exciting for the community. There is so much potential there I can't even begin to imagine. I really can't wait for the CPU mining to come back, I was really enjoying it before.

I was just reading through the Gridcoin Reddit page and there was a very interesting suggestion to have custom Boinc projects like 3D rendering and have miners getting bonus payments for participating. I think this would be very entertaining for all GRC miners and would strengthen the community quite a bit.

http://www.reddit.com/r/gridcoin/comments/22k6cs/what_are_some_of_the_first_places_that_might/
This is a good idea, and on that front, I made some progress.  I have tested the creation of our very own boinc project, for the Gridcoin Foundation, thay may include humanitarian voting buttons, a Gridcoin Police module, and a stock-option analyzer.

The Gridcoin Boinc project can be cpu-mined like other boinc projects.
Also, our future extensibility allows users to "plug in" whitelisted boinc projects into gridcoin, without an app update.  All network stats are re-tallied automatically.

Also, if we add in 3d farm rendering, we can plug that into the foundation as a windows application.

This is not "pie in the sky" either, Im very serious, and our devs (that is my helper and I) have already created an actual boinc project, so this is very exciting for our future.

Cpu mining
Traderman was asking about the status of the CPU Mining release (which does contain the heartbleed fix).

We've been working hard on the cpu miner version, focusing on testing it properly for the last 3 weeks, and we are running a little behind schedule due to a few technical problems.

However, I would like to announce this version is better than we expected, including new features that were only possible to be included while the body was on the O/R table.

For example, we added ASIC resistance, requiring GPU miners to post boinc CPIDs/RAC/Project Name/BoincAuthkeys along with getwork() requests, thereby forcing our miners to run boinc.  Also, we added in CPU PoB algo resistance to slow down the ability to port the Cpu miner code to a GPU.  We did that by adding in a brand new algo to the coin:  AES512 encrypted blockhashes.  Since each CPU hash must make a round trip after being skein hashed, then AES encrypted, it will be much harder to port AES to a GPU due to the large code footprint and business logic requirements to shift the RAC inside the Skeinhash to the proper positions in order to test the validity of the AES hash.

The code is now 95% tested, and we are in the burn-in phase.  I envision testing for a few more days, and then as we get closer to the weekend, announcing the exact block number for cutover and date to allow the exchanges to be ready to switch.  If I were to take a guess, I would say within 7 days.

Best Regards,
Rob

downloaded client from grid coin.us
can't sync .....
added nodes from https://cryptocointalk.com/topic/9199-gridcoin-supernodes/

re installed 3times rebuild block chain nothing worked....
google says GRIDCOIN is more likely fail coin... how many forks have there been every 2post is about sync Problems or forks...
can someone please make an FAQ how to instal this wallet or sync it...
Thanks

Have you tried upgrading from the console?
Also, that's weird but going in option > network and unchecking the two boxes made it work for me.
Good luck; the client is indeed rough around the edges, but a coin that contributes to science is a unique concept that is worth supporting and has lot of potential.

All, if you have problems syncing after downloading the "Prod" MSI, please upgrade like Andrew suggested.  I believe we have an older MSI sitting out there, and I will fix it asap, but the version should be "2.1.0.7" in order to sync.

The command posted above worked to get my other rig working/mining but I think I may just switch those other two back to potcoin and sell that to buy some GRC Smiley  The mining process is pretty resource intensive and the biggest issue is running the GPUs and the CPU at 100%, cpu at 100% lowers the gpu speed but also draws a TON of power, I have a 1300watt platinum psu in some of these rigs and w/ 3-4 gpus + cpu its just to much.

Seems like its faster to mine something else and just buy the coins from you guys Smiley
Chiz,
Whats the status on your gridcoins?  How many did you mine so far?  Ill chip in a few thousand to help cover the loss.
BTW, I was able to add that command you requested from BlackCoin, but it wont be out until we release CPUminers release, and re-open our code repository with a new checkout-compile system.
So, if you can wait a couple of weeks, you can try resending that tx to the user.

Cryptanalyst castrated by his government, 1952
I'm getting an "untrusted connection" message from the usual https c-cex link right now. Anyone know what's up?

Edit: it's normal again now and the site has a new look. I guess they were just in the middle of maintenance. Probably heartbleed jitters on my part.

I was wrestling on this in the past couple of days. In the end, it appears I have memory leak or something.
I ended up restarting the computer and surprisingly my hash rate is back to normal.

Much appreciated for the help, BenHur and Traderman.

John

My Scrypt Sleep level is 80.46%,now in 68th.

Sometimes the video drivers got error,and the mining speed can't reach normal speed.
Uninstall the old one with amd cleanup util and reinstall the new video driver may help.

I had that same error with my 7950 rig, once i added more ram i could increase the intensity and everything was running fine.

Thanks, Benhur.
I used the following cgminer.conf for 7970 and got 230KHPS.
I was using "gpu-threads" : "1", after changing to 2, the performance improved from 110KHPS.
But no matter what I do next, it is capped at 240KHPS. I can not increase the intensity either as the HW error increase dramatically if I change it to 14 or 15.

What is your Scrypt Sleep level?

I use external cgminer,and it always works fine about three months.

After update the wallet software yesterday,the speed is just like before.
Here is my cgminer.conf,r9 280x got 700~720kh/s,7950 got 520kh/s:
