[ANN][PWC] Project buried

TL;DR All blocks mined with NWO's orginal client after block 109680 can't be traded in Coins-e because this was a hard-fork, and those coins are in obsolete chain. Without updated client you can't send any prior coins either.

I've been interested in innerworkings of coins for sometime, after getting a "go ahead" from NWO (orginal powercoin dev) I decided to give this coin a closer look. What I've mostly done so far is that I updated coin parameters towards nowadays requirements. As some of you might remember this coin was "killed" with 51% earlier so I added something little to ensure more secure chain. This is initial client update, and I couldn't do much more without breaking compatibility to NWO client. In the next update I have more tools, because everybody is using this client

new block setting in summary:

45 second blocks (compared to old 30s), less stales is better imo.
3hr (240 blocks) retarget interval (old 12hr / 1440 ), faster retarget = less stalefest / stuck at high diff.
6x retarget limit (old 4x), diff adjusts better compared to hashrate changes.
60 PWC per block (old 40 PWC), I want that "new" coins have same value than "old".
same coin cap.

added more checkpoints.
added external checkpoint file, no need to download/compile new client just to add checkpoint.

- Users can add checkpoints into external file at
  C:\Users\'USERNAME'\AppData\Roaming\Powercoin\checkpoints.dat
  ~./powercoin/checkpoints.dat

  format is:
  blockheight hash

  example (which is actual checkpoint) is provided in the package, copy it in to the data directory.
  checkpoints from the file are added on the fly. If the checkpoints doesn't match your current blockchain client tries to hop into right blockchain automatically.
  Removing checkpoints requires client restart (you need to first remove it from the checkpoints.dat).

  I'll provide checkpoints at this thread, to ensure we all work on same chain. You need to manually edit checkpoint.dat (I'll add functionality for it to commandline/UI later)

lil tweaks to irc settings, new channel and prefix. I wanna take PWC more apart from LTC, as they share some common parameters (It was possible to   connect powercoin client to litecoin client. It still is but now were closer to remove that).

client is available at:
http://ge.tt/api/1/files/87ZDP2n/0/blob?download
win32 binaries only, sorry.

rest have to use source:
https://github.com/urpoapina/powercoin.git

example powercoin.conf:
rpcuser=user
rpcpassword=password
listen=1
server=1
testnet=0
rpcport=9863
port=9862
addnode=94.237.84.48

pools:
p2p -
http://94.237.84.48:9777 (1% fee, mine, damn ugly but supposed to work, supports +0.00xxxx, stratum)
http://next.afraid.org:8113/static/ (updated)

conventional-
http://94.237.84.48:9900 (1% fee, used for giveaways etc...)

http://silverwolf.ath.cx/pwc/ (old client, dont mine here)
http://pwc.minepool.net/ (old client, dont mine here)
http://pwc.cryptcoins.net/ (old client, dont mine here)
I have contacted these pool operators with no responses....

exchanges:
https://www.coins-e.com/exchange/PWC_BTC/   (using our chain)

blockchain explorer:
http://94.237.84.48:9902

this is a Mandatory update.

btw my motivational / dev fund is at pLWX8axRvcf4TLPHqAKjQUzNYCER22ZLJ2

If you notice that you're client says that youre 200k+ blocks behind you have also connected to litecoin network.
Go download updated client, issue has been taken care of until I can separate us from litecoin network for good.
fixed in v1.011

Other
 - Fix mining with QT (low priority)
 - Blockexplorer / pools, other supportive stuff (altcha, silverwolf... Im looking at youre way )

[jasonslow]

This great news +1.

[mercSuey]

how about your marketing campaign?  will my eyes explode if I download the new client?

[minerapia]

I let my coding do the marketing, I have some ideas tho... 
btw. UI is the same.

I thought the attacker had lots of coin waiting to be dumped. Not sure if it is good idea to resurrect the chain.

[minerapia]

Theres over 400k 4M coins mined anyway, so I would trade with caution. I dont have exact details how many coins attacker did get

[jasonslow]

I thought the attacker had lots of coin waiting to be dumped. Not sure if it is good idea to resurrect the chain.

The powercoin trading was not stopped after the attack. The trading was transferred to coins-e. If the attacker didn't deleted the wallet he could dumped it already. I think the attacker has 10% of all total pwc now.

If someone has debug.log from the time all that happened I would be interested to look at it

Is it possible to add proof of stakes to powercoin?

[minerapia]

I havent really even considered it, because it wouldn't be "fair" to add it when some ppl have alot of coins allready.
I have some somewhat similar ideas tho...
Suppose nothing is impossible when holding the source, but it could possibly require step-by-step implementation and it could possibly reflect into future blocks only.

I think security is more important. What if the attacker attack again. You can make the interest very small in the first month like .1% second month .2% and so on. Once the price go up and down I'm sure pwc will change hands many times.

[NWO]

Fantastic work minerapia! You're a really talented dev, you have my full confidence and well wishes in resurrecting PWC.

[Hydroponica]

Why the hell, would you choose a dead coin, that was attacked, and nobody likes. There's lots of failed coins to choose from

[mercSuey]

I'm willing to bet BigVern at cryptsy has a debug.log file stored somewhere.

[minerapia]

updated qt client with small ducktape and glue patch which stops fetching blockchain from litecoin.
sorry for inconvenience, I prolly spent too lil time on QT as I were busy testing settings change fuctions.

[simichent]

is there any reason i would get a weird block reward 43.80 ?

[minerapia]

Thanks, tho I smell a scent of sarcasm here

Why the hell, would you choose a dead coin, that was attacked, and nobody likes. There's lots of failed coins to choose from

Maybe this was a wrong coin, I am bit of a noob and had no bad wibes from this coin (as I werent altcoiner back when this was launched).
Reasons I went on this was:
 -allmost dead coin = I can run some tests in mainnet without messing other ppls mining.
 -allready listed, very low value = No need to "sell" this to exchanges, not much money involved if I **** this up
 -cought my eye in coinchoose
 -I really didnt want to launch new coin, I'm not that much into marketing.

maybe I could have found better candidate, but I'll stick with this for awhile.

[minerapia]

theres prolly 3.80 PWC fees included in the block. which hash?
