What's new in 0.1.5:
Quote
First release of primecoin core wallet based on latest bitcoin 0.16.0 code
Full MacOS X support

This is full-featured wallet compatible with current Primecoin network (no any soft forks implemented), you can begin use it now instead of old Primecoin 0.1.2. How you can begin work with this wallet:

1. Synchronize from network.

2. Use bootstrap http://primecommunity.org/bootstrap.7z

Put bootstrap.dat file to data directory, no any difference with other Bitcoin-based wallets.

3. Use old client directory.

Client ask you about reindexing database, usually it takes 4-8 hours depends on hardware.
WARNING: index database format incompatible with old client! If you want continue use old Primecoin 0.1.2, backup your data directory with blocks, chainstate, index and wallet.dat!

About intermediary nodes.

Primecoin 0.1.2 cannot be block source for Primecoin Core wallet, to solve this problem was created intermediary wallet version 0.1.3. If you want support primecoin network, you can create intermediary node based on sources https://github.com/primecoin-ng/primecoin-intermediary (binary releases coming soon). Current release contains 5 hardcoded nodes for bootstrap, other nodes will be placed here.

Pool mining:

Miner uses custom binary protocol first time implemented in xpmclient (Primecoin GPU miner). Working pool instance: http://coinsforall.io/#!/coin/ZCASH

To start mining:
 - Put your T-address to config.txt (need ZCash client installed, online wallet or exchange with ZCash support).

Quote
server = "coinsforall.io";
port = "6668";

# Your ZCASH payout address (t-addr)
address = "t1ZsLopJKzyuaqmeC2Y6cx1351G13st2sWN";

 - Configure your GPUs (edit corefreq, memfreq, powertune and fanspeed parameters)
 - Run zcashgpuclient in Linux or zcashgpuclient.exe in Windows
 - Put you address to 'Your Address' field on web site for monitoring workers and payments

Pool system: PPLNS (Pay Per Last N Shares); accounting procedure uses all your shares received during last hour. Payment delay: 1 hour or less.

To start mining:
 - Put your addess to config.txt:

Quote
server = "xpmforall.org";
port = "6666";

# Your XPM payout address
address = "AMgtSW8ge2mvqxaiWo11GqTKx6rQ2J57yA";

 - Configure your GPUs (edit corefreq, memfreq, powertune and fanspeed parameters)
 - Run xpmclient in Linux or xpmclient.exe in Windows
 - Put you address to 'Your Address' field on web site for monitoring workers and payments

Pool system: PPLNS (Pay Per Last N Shares); accounting procedure uses all your shares received during last hour. Pool fee is 4% now. Mining calculator included!
If you want to help decentralize primecoin mining and support open source, welcome!

Solo mining:

Quote
The solo-mining server code is at: https://github.com/madMAx43v3r/xpmserver

The solo-mining server binaries can be downloaded at:
For Windows: https://mega.co.nz/#!hRAmGRAQ!cbYlm-meXprzImw-vQ5COnBQiWtgPFXJeJtTs-041AI
For Linux: https://mega.co.nz/#!NZAHWC6b!FyeF6aKZ32KPs_Ns0NwZsEGaOWkNAlwfSz76hO-Dg_k
Note: The windows version crashes on shutdown, have not been able to fix this.

The binary zips also include a README.txt you should check out to get started.

EDIT: If you have dynamic ip: There is a bug somewhere in the bitcoin network code that can cause the server to loose all connections to the network after your external ip has changed. It will still show 8 or more connections but if you look in debug.log you will no longer see new blocks or transactions. In this case you need to restart the server.
The chance of this bug to happen is around 50%. So be careful, if your external ip changes and you don't check the server and the bug has happend you will produce 100% orphan blocks.

Difficulty target switching F.A.Q.

Quote
Why my CPD dropped so much after switching to target="11" in config.txt?

Primecoin proof-of-work certificate is a Cunningham chain https://en.wikipedia.org/wiki/Cunningham_chain, rational part of difficulty is a chain length (for example, difficulty 10.991 means that PoW certificate contains Cunningham chain of 10 prime numbers). Target option in config.txt is target Cunningham chain length.
CPD (chains per day) shown by miner is not absolute, it strongly depends on chain length configured by "target" field! 15 CPD with target=10 and 0.59 CPD with target=11 is same speed.

Quote
Miner shows 30 times less CPD, will my profit be 30 times less?

No! If you use calculator and put CPD with target="11", check difficulty field, it must be 11 or more. Look these screenshots.



Quote
When I need change target in config.txt to 11?

Now switch point is 10.994!
First, switch point was at 10.991, but too few miners updated their xpmclient to 10.2 or manually changed target to 11. For properly work, all miners on pool must use new target settings, but in practice itís not easy.

Quote
What miner I need to use ?

Most recommended miner is xpmclient 10.2.2 http://coinsforall.io/distr/xpmclient-10.2.2-beta.tar.gz with target=auto and width=auto settings.
Also you can use previous versions and manually setup target and width in config.txt.
xpmclient 10.2 with target="auto" not recommended now, because it uses difficulty 10.991 as switch point.

Quote
What happens if I will use invalid target settings?

You will get less profit:
* difficulty < 10.994 and target="11": miner will generate less amount if shares.
* difficulty > 10.994 and target="10": big amount of shares will be marked as invalid.
