It's really sad ... I got the my coins out but I still have 2 unresolved deposit issues open.  Support keeps trying to close the tickets but I keep telling them I don't see the deposit.  I've even included the transactions details on the blockchain.

It's under 1,000,000 grain.  Not too much to loose...  Just have to write it off...


BTW,  My private pool still running.  PM if interested.

FYI - I received all remaining Grain from Swisscex.

I'd like to see a updated updated wallet with coin control and checkpoints.   Any plans for the near future.

Looks like Grain should still be around? Great! Though I could use some nodes to sync up... I'm coming from an OLD wallet Smiley

Let me know? And congrats for keeping Grain alive!

I have sent a request to the guys from Cryptopia to add this coin to their exchange.  Actually, I am waiting for the coin review, but am sure they will add it to their voting page.

( quotes edited for readability and presentation )

@TillKoeln,

    Yes, good work. Indeed they have added GRA to their voting page. Today, I have registered and voted for us to be added to the exchange. Thanks for doing this in January and sorry we took so long to respond. I have been mining the blockchain this past week to catch up since I last was mining Graincoin in January and my CPU has been staking at 100% for more than 4 days straight ( in addition to solving new blocks ).

For Grain at Cryptopia today!
Note: At the end of each weekly round the votes are reset.

Here are the only two full nodes on the network which I have found to peer with presently -- when I discover more I will update this post to share so others will be able to sync more easily in the future.

addnode=204.45.207.186
addnode=73.44.156.111

If you find this information helpful, please register at Cryptopia using my Referral Link

Kind Regards,
-Chicago

Anybody wanna join me in minting some Graincoin tonight?

    The chain is moving, there are the two peer nodes mentioned above both online and you should be able to sync without issue.

    I have a small ASIC ~28MHash/sec pointed at it presently.

----------

    If you're not mining Grain is it because you would prefer to find a pool?

    Please advise.

Kind Regards,

Hello,

    I found it weird this happened as for more than a year Grain has had no trouble remaining connected to peers.
    At present, the only node which has a connection with me is Miner-TE and no one-way connections.

    I'm doing some mining now in an effort to ensure if there is a fork, I remain on the chain with the most work. If you are connected to Miner-TE or 73.44.156.111 you will also be on the correct chain.

Kind Regards,

Chicago

Why does Grain run at 100% CPU 24x7 while staking?

If there were more people on the network running full nodes would my CPU usage be less?

I think the efficiency will be getting better because more people help the network, your CPU usage has the minimum usage of 1 % - max around 97%. you can tweak how many priority it can have or the amount of processors you want to work on the GRA -QT with taskmanager. Now I m also running the QT again because low diff but it all have to stay in balance for the best results.

Version 1.6.2 Released. Download links for Windows Client and source in github are updated. To save your time and resources the separate link for blockchain data is provided in downloads section.



Please vote Graincoin for being added to exchanges:
For cryptsy:

A grain is a unit of measurement of mass that is nominally based upon the mass of a single seed of a cereal. From the Bronze Age into the Renaissance the average masses of wheat and barley grains were part of the legal definition of units of mass. However, there is no evidence of any country ever having used actual seeds or cereal grains. Rather, expressions such as "thirty-two grains of wheat, taken from the middle of the ear" appear to have been ritualistic formulas, essentially the premodern equivalent of legal boilerplate.

- from Wikipedia




Graincoin (GRA)

Graincoin is a PoW/PoS coin that is designed to be the unit of cyber-coin. It has a total of 50 billion unit to be released, through a fair p2p mining process. It is fast, secure and have sufficient coins for circulation so it can be used in real daily shopping.

Graincoin is from the family of PPCoin/Novacoin with latest available algorithms that fixed various problems in the PoW/PoS coins. As compared to the PoW only coins, the proof of stake coins are more resilient to 51% attack. Also it is a long term energy-efficient crypto-currency since not all coins are obtained by mining.

Each graincoin block provides random 1024 - 2048 grains initially. It also provides rare superblocks. The coin uses hash-based algorithm to determine superblocks based on the number of 9s in the previous block hash. It works as follows:

- the hash contains six 9s or less: regular block
- the hash contains seven or eight 9s: 8 times the regular block (about 5% chances)
- the hash contains nine or more 9s: 64 times the regular block (about 1% chances)

Premined 1% as reserved bounty and reward for developers, giveaway, pool, explorers, etc. Graincoin also provides 5% annual interest on the grained held. The interest will be paid about every 2 weeks.





Specifications

   - scrypt
        - 30 seconds block target
   - 1024-2048 grains per block for normal blocks
   - 8 times or 64 times the regular payout per block for super blocks depends on the number of 9s in the previous hash
   - Difficulty retargets every block
   - mining payout will be halved every 90 days (259200 blocks)
   - minimum payout per block 1 coin
   - Total grains will be 50 billions
   - 6 confirmations for transaction
   - 50 confirmations for minted blocks
   - PoS interest 5% yearly
   - PoS min age 10 days
   - PoS max age 30 days

   - Ports: 11054 (connection) and 11055 (RPC)

To save your time on synchronization or reindexing the blockchain, download the blockchain.zip file and unzip its content into %APPDATA%\Grain folder on Windows systems or into ~/.Grain on Unix/Linux systems. If you choose this possibility and have existing wallet then start the grain-qt/graind with '-rescan' option for the first time after unpacking the blockchain files.


Mining Configurations


Sample Config File (grain.conf):

Quote
listen=1
daemon=1
server=1
rpcconnect=127.0.0.1
rpcuser=**Yourusername**
rpcpassword=**Yourpassword**
rpcport=11055


How to Solo Mine

1. Start up grain-qt, wait for it to load, then exit.
2. Put grain.conf (see sample file above) in your c:/users/**yourcomputername**/AppData/Roaming/Grain
3. restart grain-qt, and you should connect and sync.
4. For solo mining, launch cgminer or the mining program you use and begin mining.
      cgminer ex: cgminer.exe --scrypt -o localhost:11055 -u **yourusername** -p **password** (without **)


Here is the link to original GrainCoin thread for historical purposes.
