Worldcoin has been released to the world for about 3 months. We designed WorldCoin to be fast enough for day to day transactions but still very secure. Full confirmations occur in about 60 seconds or less. However, it has come to our attention that there is an issue with orphans, and we would like to address this.

Today the v6.4.1 patch has been released to address this issue. Block times, reward, and confirmations have been modified. NOTE: the amount of WDC created per day has stayed exactly the same.

1. Block time changed from 15 to 30 seconds.
2. Block reward changed from 32 to 64 coins (to maintain the same number of coins/hour).
3. Confirmation amount changed from 4 to 2 (to maintain current 1 minute confirmations).

There are a few other changes as well:

1. The current coin reward will not halve at a certain block any longer. Instead, the reward will gradually decrease 1% every week.
2. If the reward reaches 1 WDC, it will not decrease any longer, but will stay at 1 WDC/block for the life of the coin.
3. The difficulty will update a maximum of 10% either direction every 120 blocks or ~1 hr (vs the current 400% per ~8 hours).


Specifications

Block Time: 30 Sec.
Confirmations: 2
Difficulty Retarget: About 1 hour (120 blocks)
Block Reward: 64 coins, reduced 1% every week (20,160 blocks)
Coins: 265,420,800

A year after the patch, we estimate the reward to be be around 38 WDC/block, or about a 41% decrease during that time period.  After 8 years, it is estimated that the reward will be at 1 WDC/block.

This patch will take effect around August 30th, or at block 600,000. All users should update their wallets and daemons to the new version by block 600,000-older versions won't work after this point.

I know a lot of people have really been anticipating a patch change.  Make sure to update before block 600,000!  :D

I'm pretty excited about this. I think it will greatly reduce the orphan rate...

The 1% decrease a week sounds good. Should still give enough time for new miners to get a lot of coins.

any nodes?

the client is on the old algorithm until aug 30th so I'd assume you can keep using same nodes...

Hm.. interesting. I may stock pile some coins.

edit: This client indefinitely hangs for me. Even after the blockchain has been downloaded.

Hmm, I wonder why that could be. Are you running the windows version, or on linux/apple? Have you tried deleting everything but your wallet.dat?

Windows 7. I've got about 12 clients on this computer and all work fine.

I think I'm going to get the previous version and have it download the blockchain again.

edit: Hm.. this one is hanging too. I'm going to try to use the worldcoind.exe to download the chain and then run the QT when that's done.

Git source will not compile on Linux. Attempted on two systems (CryptoCoin Explorer server (Ubuntu 13.4) and local development system (Mint 15 KDE)

Daemon compile errors out with :


QT compile errors out with:

Fair patch, I like it

Ahh, yes. We were running into this error as well. It was due to the obj dir not existing in Worldcoin/src with full permissions. That is currently being added to the git repo. Thanks for pointing that out.

Edit: This has been added to the repo and a fresh download from github has been confirmed to compile worldcoind and worldcoin-qt.

Interesting. I have the client up and running on windows 7 x64 (https://i.imgur.com/aWfXh1H.jpg (https://i.imgur.com/aWfXh1H.jpg)). Did your blockchain re-download work?

same problem

in src dir "mkdir obj"

Awesome news, and great work! Very sensible changes which will help WDC come along.

Will update my client next time I'm home.

I figured it out. It's been a long time since my yacoin client has prevented other clients from starting. That was it.

Updated without a problem, thanks (windows 7) :)

K.

sounds like a good patch, updating my client as soon as i get home :)

This part is and always will be up to the vendor. Whether or not it appears as confirmed for regular users after 2 blocks is irrelevant to a vendor who will no doubt be using getbalance <account> 6 at the very least for any coin.

2 confirmations is too low. Any vendor has to use at least 5-6 confirmations.

Err, what about that PDF that was promising halving the reward after 3 months ?

That proposal had too drastic of a change.  There's a good chance we might have killed off the coin doing so.  Losing all miners in 7 months at that rate.  This was discussed with many dev's and miners, and the consensus was a more gradual inflation schema was the best thing for the coin and the community.  This patch is not meant to be a get rich quick scheme for all the current holders, it is here to help address the orphan issue and help inflation changes to happen gradually.

Thank you for clarifying situation.

No problem! :D



NerdCustoms

This is a much better patch then was originally announced. Good job team!

omg...we're at 750 mh WITHOUT multipool. Go hash! :D

Awesome i have waiting this Announcement! for week! now its true!
Good Job!

make sure all of your libboost dependencies are installed and git clone from here ...

https://github.com/worldcoinproject/Worldcoin

not here ...

https://github.com/worldcoinproject/Worldcoin.git

Agreed, good point.

Has everyone upgraded to 6.4.1?

I am getting an error when closing. It says shutdown unexpectedly. I am using on Windows 7.

I am unable to replicate this issue in windows 7.   Can you maybe give more details?  How do you exit...file > exit, or just X out.  These shouldn't matter, just trying to narrow your problem down.  Do you have UAC settings enabled in win 7?  Are you waiting for the wallet to fully close before clicking on other apps.  Any errors in event viewer (start > search type event viewer)?  Do you have other wallets having the same problem?


NerdCustoms

I did through exit and it gives a message saying the application has requested the runtime to terminate it in a unusual way. I did again and it happened again.

You might try running windows updates and make sure everything is updated.

also, as I mentioned before, please look in Event Viewer at around the time this happened.  There should be errors that help narrow the problem down.

Have you tried running your computer in safe made to see if the problem persists? etc..  I find it helps to take notes when troubleshooting. You may have an underlying hardware or driver issue as well. I can't stress this enough, Event Viewer would be the best place to narrow this down further.

Please keep me posted.

That's all great and I agree with it but just as with UNOCS you fucked up lot of people that invested based on stuff you are advertising and promoting.

Keep your fucking mouth closed before you release something or let the other people do the job you guys are doing because you are obviously shit in doing it.

I'm not even sure what you're trying to say here, or how people have been screwed over from this patch?  If you would like a better response, please explain in more detail and less cursing.  Perhaps you're just reading the patch wrong. 


NerdCustoms

People have been screwed as many of them have invested in WDC after you advertised the patch with seriously less coin generation. I completely agree it was a risky approach and this patch is generally much better one but what I don't agree with is that you keep missing to do what you promised before and make people that invested based on your promises to look like idiots after you fail to deliver.

So, stop fucking games with investors  and stop announcing pre-releases you'll fail to deliver, and stop fucking playing with WDC public image as some of us have spent a lot of money investing in it and supporting it when there was no signs of patches or unocs things. If you don't know what you are doing, then do consultations before you announce stuff with fancy PDFs just to do it on completely different way.

Blasphemy!!

Who doesn't like fancy PDFs??

Please note that community leaders changed since that first announcement. There were formal announcements on the Worldcoin forum about community leadership changes.  This might be why you are upset, and I do apologize if that is the case. I personally think you would be more upset if the original patch had gone through. Worldcoin would probably have lost all miners inside 6 months, thus opening us up to easy 51% attacks.  There are quite a few of us investing in Worldcoin as well!  Myself included.  I'm sure a super fast inflation change would have been awesome if prices doubled every single month to keep up with it, but that's just not realistic, and that is DEFINITELY not a good enough reason to patch a coin.  Patches should not be made with greedy intentions.  I hope you find that the current patch was made with the best of intentions for the coin and the community as a whole.  We will try to be more transparent in the future.

The current prices you see dropping are not just in Worldcoin, look at most of the alt coins.  They are dropping because they are tied to BTC and BTC moving averages show us we're in a down trend.  Down trends = sell off.  People get out of altcoins, back into BTC, and sell off into fiat.  This happens nearly every time BTC drops in value. Current price drop has nothing to do with the patch and your anger should be directed elsewhere.  

Best Regards,

As I said, I don't mind change in patch design, it's fairly better than original one, what I care about are nontransparent changes and non-delivered promises.

I don't care about price drop apart from not being able to pick more coins as I went all in after another failed promise - unocs one.

But what I care about and hope to stop seeing is this level of unprofessional treatment of investors. Things must be much more professional in the future, moves and changes well thought to stop nontransparent changes and inside trading and any pre-announcement completely cut off if there is 0.0001% chance of non delivering.

Wut is there promises? not seen anything ^^ i promise that if u start mining WDC u never want stop mining it  ;D
i trust WDC Its coin from future!  :-*

lol well said StatusD :D

I might be the biggest WDC holder out there or at least one of the bigger few so please don't talk to me about trusting it ...

I'm definitely not the biggest fan of the way WDC stuff is handling out things though.

http://wdc.ltcoin.net has upgraded.
welcome to mine here

Yeah, after thinking about your clarification, I concluded that this patch has fcked up some people.


I know 3 individuals all investing into coin hoping that the patch will deliver halving of the reward, each holding 500k+ of coins. I'm pretty sure your patch made the coin go wrong way. Instead of expected uptrend the buy orders were removed and coin value dropped from 0.00008 to around 0.00007.

The prior inflation scenario, would have essentially turned this coin into a premine scam for everyone who currently held coins. Instead of a couple of you complaining right now, we might have 50 people yelling premine scam.  Which is worse?

I don't know.

I don't hold that many wdc to make it worth arguing/possibly making enemies. So I can just wish you best luck. The 500k+ holders will have to express themselves for themselves, if they want to.



ps: I also edited the part of my last message. I was too agressive with the suggestion.

Too bad none of you complainers backed me up the other month when I complained loudly and articulately why it was a bad move for Worldcoin to join UNOCS without any form of prior public debate or transparency.

Same shit has happened again with this patch and now some of you are finally starting to cotton on why it's bad that a couple of people get to pull all the strings behind the scenes and make the decisions, with no public debate or transparency beforehand.

Good job I sold my coins back then, I advise you all to do the same.

You're fine, you've been polite and level-headed with your responses. Nothing wrong with constructive criticism and intelligent debates.


Thanks,


NerdCustoms

Confirmation amount changed from 4 to 2   ....why change to 2 ??? ,i dont think so its  Transaction Security

Cannot download the lastest patch, get "could not connect to worldcoin.unocs.com"

Please advise, tks.

I cant download it too. Please reupp and make it in your website. Please write the correct md5hash from the original binary exe for windows.

I am having the same issue. Devs - please fix! :)

Also, can someone tell me why wdc.epools.org is producing SO MANY orphans currently? Is this a network-wide issue or just this one pool?

because difficulties has dropped and so profitability is very high => miner rush,multipool switch ... => block time even lower (7 second) => orphan

Thank you, lucazane ! I am still learning all the nuances of this stuff, and I appreciate your help  :)

We the people still need a working link to the new client, devs!  :-\
