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!  Cheesy

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.

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.

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). Did your blockchain re-download work?

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