Do you know something we don't? Smiley

Looks like we are up to 60 mhash and difficulty has definitely risen past few days.

http://explorer.gridcoin.us/

yes, it hits 69M earlier today. Tomorrow it will break 70M.

what do you mean? Smiley

Hi, Grid:

If I understand correctly your new SQL based p2p crypto-exchange mechanism can be used as an effective Proof-of-Stock mechanism.
This may be even superior than Datacoin where they allow storing of some amount of data in the blockchain.
Can you shed some light on the differences?

John
I'd like to roll out SQL in phases:
* Client synchronization for standard data, blocks, tx, leaderboard - existing information that we can use for transaction auditing - all info can be harvested from the existing chain
* Full p2p distributed ledger: In the future, the ability to roll out data structures that are fully replicated and synchronized among our p2p network automatically.
* PoW (or PoS) based on the dissemination of the data itself.  Useful for CPU miners and for validating the integrity of the data (rejecting any injected data not approved by the network)

We have partially finished #1- you can query blocks and credit information from boinc.
#2 and #3 requires an expanded SQL spec; replicating the schema is fine, but Im working on the mechanism that secures the synchronized "official" ledger state.

From a high level, I think if we roll out a cryptographically strong formula that locks each row to a block key and block time and rowhash, and prunes old data, it would work.
The process itself of creating the rowhash may be the key to the PoW required for SQL replication; For example, if it takes time and effort for a client to generate the rowhash for new data, that is part of the PoW required to add info to the sql tables in order to be accepted by the network.

Yes, in theory, the SQL future features may not only be able to store useful data for the coin (such as the data you referring to) but we may even be able to set up pointers to
  web resources to store things like files that everyone can download - obviously to resources that have no point of failure and no central authority; etc; but Id like to focus on the SQL replication first.

Thanks,
Grid

Just upgraded the web site to HTTPS:
https://www.gridcoin.us
 
Working on the issue where chrome showing a malicious download and I have found a path to resolution but its going to take a few days (at least):
* Site must be HTTPS (SSL) for the download - Done
* Sites owner's Org (gridcoin) must sign up for google webmaster tools - Done
* Site must find what virus ever existed and flagged in google database - Done (was cgminer.zip, extracted contains password cracker which as we know is really a miner)
* Site removes the malware (done... cgminer_base64 is not flagged as a virus, tested)
* Site must re-apply for evaluation from google (done)
 
Now we wait a couple of days to see if they clear the warning for gridcoin.msi
 
Best Regards,
Rob H.

yes, please all reply to the topics. GRC needs everybody.

Voted.

TribalBob: We'll keep working on ways to fix the heuristics issue; I'd rather not have the problem to begin with.

I want it to stay low Wink

I just checked the block explorer, it is @ ~ 1.7!

difficulty is finally more than 4 because more Chinese know this coin.



Hashrate the first time reach 60M, towards 70 today.

It hits 4.7 this morning, you can check the chain history.

DGbet.fun - Crypto Sportsbook
New Version Available:
Release Notes : 1.1.4.9/50/6.7.2: Install from MSI: Yes

Please delete c:\program files(x86)\gridcoin\*.* before installing; install from the MSI (our upgrader has been modified).

1.  Added capabilities to the auto-upgrader to upgrade any file in gridcoin
   & provide the ability to add new files & the ability to upgrade the upgrader.  
   Designed to remove the necessity to install from the MSI in complicated circumstances.
   The Upgrader will now try to upgrade each file up to 6 times before failing (HTTPWebFailures).
2.  Moved the SQL database to the Data\SQL directory to avoid ReadOnly issues.
3.  To attempt to remove the heuristics cgminer failure, we now include cgminer_base64.zip as a base64 version of
   cgminer.zip.  Gridcoin will decode the base64 file before using it when creating a new mining instance.
   Note: You may replace cgminer.zip with your own preferred version of cgminer: Place it in the DataDir.
4.  Added checkpoints.
5.  Added homogenized utilization breakdown for easier tech support.  The "Breakdown:" value is located in the
   mining console near the bottom right.
    The first component is the processor/thread utilization and the second component is the avg_credit calculation.
6.  Modified the boinchash to include the necessary leaderboard fields: boinc_project_hostid,
   boinc_project_avg_credits, boinc_projectid, and boinc_project_name.  Also added the SQL table Leaderboard, so that reports can be written with the
        gridcoin network and boinc credit information.  The chain has been modified to store 3rd party security verification by one of the 60 public boinc APIs for future avg_credit verification.
7.  Added Copy-Paste capability from Query Analyzer and the leaderboard.
8.  Added the Leaderboard to the client (Main menu: Leaderboard).  This screen is designed to:
    * Collect global network project average credits so that we can calculate factors
        per project (done in a dynamic way, so the factors are not hardcoded in the client)
    * Compile a list of Boinc Leaders per project (GRC Address project_credits sorted desc)
    * Provide a report for visibility of the Global Network Statistics per Project and Public Factor values
    * Provide a report of GRCAddress Leaders for the network
    * Provide a report of GRCAddress Leaders per project
8b.  Note: The leaderboard contains test data; we will need to wait 14~ days for users to upgrade to this version and blocks to be solved and new data to be stored before we can start using the feature.
8c.  Anonymity Statement! : If you are feeling we are desregarding your privacy by creating the leaderboard please read the following statement:
   * The network avg credit factor per project is required for us to develop future enhancements to the subsidy algorithm: That is because the official boinc project credits vary wildly;
   therefore we need the network avg per project to implement future algorithms.
   * The Public GRC address in the leaderboard is stored so that we can apply 3rd party credit verification checks through the Boinc APIs (by other GPU miners),
   for the benefit of the integrity of the coin and exchange value.
   * The leaderboard does not collect or store any other information in the chain other than the extensions added in release note 6.
        As always your privacy is fully respected and we will not add any new features that disclose private information without being discussed and voted on that may result in positive benefits for the survival of gridcoin!
9. Updated the SQL replication engine to sync blocks faster (since we need the blocks to be synced to successfully test the leaderboard).
10. TribalBob, will you please test the virus scan again to see if the issue is resolved?  Thanks!
11. LennStar: CGMiner Invalid Count is already being updated: Mined Block number on the gui is not yet available.

Thanks and best regards testing,
Rob Halford

PS Removed the Git binaries.


PS II: If anyone downloaded 6.7.1 between 8PM-10PM CST (1/1/2014) please do an "upgrade" to 6.7.2. from the command line - bug fixed.  MSI updated: v6.7.2 is the latest...

The download is still marked as malicious by Google Chrome, I think the best solution is going to be having a notice near the download links informing people to expect the warning, inform them why the warning is happening and perhaps offer a version of the download that does not include the packaged miner and allow people to download and add their own miners...

Either way, it will be important to keep the source code on github current and have the md5 hashsums available so people can review the code themselves and compile their own binaries if they so desire.

i have an other question: is it normal that if i use BOINC with 100% occupation CPU, my hashrate decrease of 15/20%?

pls, it's important Sad


My hashrate decreases only 5% at most. Try to decease BOINC processing power a little bit and try. Find a balance point.

I love the idea of Gridcoin. I had this idea and considered to create a altcoin by my own. Then I googled a little bit and found Gridcoin. Glad, that this idea has already been realized. Great job and good luck for the coin!
