Proof-Of-Stake Info

Graphene utilizes Proof-of-Stake (POS) mining that generates more Graphene when you retain your coins for 10 days. When the coins from a
particular transaction become 30 days old, they will be used by your wallet to perform Proof-of-Stake mining that will generate new coins if you solve
the block.  Just like a normal Proof-of-Work block, these POS blocks require 200 confirmations.  Once the POS block has reached 200 confirmations,
 your staked coins and the reward will be made available again in your wallet.  These coins will then be required to age another 10 days before they can
 be used in POS mining. The PoS is not very CPU intense and there's no need to set anything in order to mine PoS. It's done automatically.

It is important to note that when your coins are staked (reach 10 days of age and are used for a POS block), these coins will be owned by you but
unavailable to transfer until they are fully confirmed.

For those who want to exclude a certain amount of coins from Proof-of-Stake mining, you can run the client with the -reservebalance
argument.  This argument allows you to specify a certain amount of coins to withhold from using as a stake.

GRAPHENE PROOF-OF-STAKE GETTING STARTED

By default, out-of-the-box, the wallet will submit coins for staking (refer to above for how this works). If you opt to encrypt your wallet (this is strongly advised) then staking will stop - as encrypting the wallet means no coins can be sent without entering a passphrase. If you opt not to encrypt your wallet (do so at your own risk) then staking will work fine, out of the box, with no extra configuration needed. There however is the ability in the Graphene wallet to "unlock" the wallet - keeping it encrypted and allowing coins to be staked.

"Unlocking" the wallet allows coins to be sent and received for the purpose of staking. Unlocking the wallet is not the same as decrypting the wallet - as the wallet passphrase must still be entered to send coins to another wallet (as per normal if you encrypt any cryptocoin wallet). Unlocking the wallet allows coins to stake whilst keeping your coins safe.

To unlock your wallet, enter this command in the Graphene-QT wallet client debug console located under help menu:

Code:
walletpassphrase thisismypassphrase 99999999


Replace "thisismypassphrase" with your encrypted wallet passphrase. This will unlock your Graphene wallet for staking for 1157 days (99999999 seconds = 1157 days). Upon restarting your client you will need to re-enter this command, as it is not saved.

By entering this command and having your wallet encrypted, you will be able to stake your coins whilst having a properly encrypted Graphene wallet.

How to mine

To solo mine using the wallets, you can add gen=1 to the graphene.conf file. You can also enable solo mining in a wallet by going into the debug console
and entering setgenerate true or issuing that command via a RPC connection. Due to the coin's current difficulty, it is not suggested that you solo mine this coin
at this time. Instead you earn more coins by contributing your computer's hash power to a pool.

As this coin is uses the Scrypt-Jane algorithm, you will need to use a miner that supports it. When mining with scrypt-jane miners that do not have presets
for Graphene, you will need to use the following parameters:

Code:
nfMin = 4
nfMax = 30
nTimeStamp = 1395744444

Supported miners include:

CudaMiner

CudaMiner is a miner developed and optimized for Nvidia cards that has built-in Graphene mining support.

Example CudaMiner command:
Code:
cudaminer32.exe --algo=scrypt-jane -o http://url:port/ -u <username> -p <password>

Windows Binaries can be found in the first post of the CudaMiner topic. For those using Linux, you will need to compile from source.

CGminer

Robert Davidson has taken version 3.7.2 of the popular CGminer and patched it include support for scrypt-jane.

Example CGminer command:
Code:
cgminer.exe --scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1395744444 -o http://url:port/ -u <username> -p <password>

You can download CGminer with Scrypt-Jane from the url: https://sites.google.com/site/rmdavidson/.
The recommended Windows download is:  https://sites.google.com/site/rmdavidson/cgminer-3.7.2-sj-0.02.zip?attredirects=0

For Linux users, you can compile from source using these instructions.

do x11 darkcoin algo, is much better, gpu run cooler less consumption

far better than scrypt-n

all devs should adopt x11 for their coin, or the heavycoin algo

And why in the topic is not specified percentage per annum with PoS mining? Or is it classified information?

Code:
walletpassphrase thisismypassphrase 99999999


Replace "thisismypassphrase" with your encrypted wallet passphrase. This will unlock your Graphene wallet for staking for 1157 days (99999999 seconds = 1157 days). Upon restarting your client you will need to re-enter this command, as it is not saved.

By entering this command and having your wallet encrypted, you will be able to stake your coins whilst having a properly encrypted Graphene wallet.


I am pretty sure the correct code is walletpassphrase thisismypassphrase 9999999 true

Got to put the true in there to make it work.

No the true flag is for something else, maybe unlocked for minting only? Either way it certainly does work without it on other pos wallets.

Sound very interesting.
(May-be it would be better if you could delay the launch by a couple of hours because of the launch of blitzcoin ?)

Regarding cudaminer, what you have written on the announcement page won't work unless you are using the same timestamps as Yaccoin (and I hope not)

The correct syntax should be cudaminer --algo=scrypt-jane:???????????:4:30  where "???????" is the timestamps
