- Proof-of-work difficulty reached a new record of 43120 at block 19080. Currently proof-of-work difficulty stays around 33000 and proof-of-stake difficulty is about 2.1.
- Not much else to report on this week. Lots of people are probably busy preparing for the holidays. So relax and have some fun after a productive year!

Weekly Update #17
Weekly Update #16
- Proof-of-work difficulty continued to rise this week and is currently over 36000. Proof-of-stake difficulty is currently 1.28, gradually rising from the minimum difficulty of 1.
- Christian (xchrix) is now running a new website cryptocoinsend.com, becoming the first payment processor supporting ppcoin.
Weekly Update #15
- The mint rate halving of bitcoin at bitcoin's block #210000 caused ppcoin's proof-of-work difficulty to ramp up as some miners switched from bitcoin mining. This week's peak difficulty is a new record at 30677 at block #17333.
- The exchange rate on bitparking seems to be fairly stable throughout the halving event when difficulty was rising fast.
- I am happy to see more people discussing ppcoin designs on the forum. I hope more and more people gain deeper understanding of the design, which is important to the future of ppcoin and proof-of-stake designs in general.
Weekly Update #14
- Proof-of-work difficulty continued to drop this week, currently at over 16000.
- Please be aware that in a few days bitcoin mint rate halves from 50 btc to 25 btc per block. This may cause high volatility in alt coins including ppcoin. So please limit risk exposure in the market accordingly.
Weekly Update #13
Have fun and next week!
- Proof-of-work difficulty broke new high this week. The new peak is at block #14952 with difficulty 25020.
- v0.2.2 has been released. This release has made some improvements to the qt gui for stake transactions. Although official gui builds are not yet supported, those users who build qt gui themselves should find the new version much more usable.
- Vircurex has started ppcoin support this week, becoming the third ppc exchange.
- Bitcoin mint-halving date is approaching soon (in about ten days). This event could cause high volatility in ppc (and other altcoin) exchanges. We strongly caution investors and traders to fully evaluate and limit their risk exposure.
Have fun and next week!
Weekly Update #12
Have fun and next week!
- Proof-of-work difficulty surpassed 20000 this week and briefly approached all time high yesterday.
- v0.2.2 release is under final testing and build. Improvements to the qt gui code have been done and qt can now properly display stake and coinstake transactions. However official build of gui would not be supported yet in this release. Gui users can either self-build or obtain community-released gui builds. v0.2.2 is expected to be ready some time next week.
- Regarding network hash rate, since ppcoin is designed with variable spacing target for proof-of-work blocks, you cannot directly compare network hash rate to other block chains based on proof-of-work difficulty. To estimate network hash rate you would need to first get an estimate of current proof-of-work spacing target (in seconds), by counting the number of proof-of-work blocks in the last 24 hours for example. The formula to calculate the total network hash rate is: hash rate = difficulty * 4G / spacing target.
Have fun and next week!
Weekly Update #11
Have fun and next week!
- Proof-of-work difficulty stabilized over 16000 this week.
- Proof-of-stake blocks account for more than half of the blocks in the past several days. It is expected in the next month or two proof-of-stake blocks would reach the 10 minute spacing target and proof-of-stake difficulty should begin rising above the current minimum of 1.
Have fun and next week!
Weekly Update #10
Not much else to report on this week. So have fun and see ya all next week!
- Proof-of-work difficulty temporarily peaked at 15732 at block #11509 this week following some buying strength on the Bitparking exchange.
- There was some effort to figure out the memory leak encountered with mining pools. So far it appears to be an elusive bug.

Week Update #9
Have fun and next week!
- ppcoin has passed block #10000 this week at 10:41:39 UTC on October 15, 2012
- Proof-of-stake difficulty has dropped to 1. Last couple of days the frequency of proof-of-stake blocks has reduced compared to last two weeks. This is because 30 days ago the proof-of-stake blocks just started appearing so most coins eligible have already participated in block generation, causing a lack of eligible coins currently. The average size of stake generating blocks are expected to become smaller in the next couple months and proof-of-stake frequency will become more stable and start pushing up difficulty from it's minimum at 1.
- Due to my heavy schedule around the end of the year, work on the client is slowed down. There will be a delay for the next release.
- There was some complaints that bitcoin 0.7 rollout wasn't smooth. I don't know the details so if there is something to take note, welcome to message me about this topic. I would probably wait a while before reviewing bitcoin 0.7 and planning for a merge.
Have fun and next week!
Weekly Update #8
Have fun and next week!
- SatoshiRoulette introduced PPC games this week, becoming the first (non-exchange) website that accepts ppcoin payments.
- Andy Rossy has provided a raw transaction rpc patch for those who needs the patch to run a service.
- This serves as a reminder that ppcoin is experimental software that I do not make any guarantee regarding its security. Users must evaluate risks on their own regarding the security of ppcoin and I can only say I will try to do my best to make it more secure.
- Some miners like to jump between currencies to maximize their profit, this is normal. Often we see ppcoin proof-of-work difficulty oscillate a bit as miners switch and this is expected. My observation is that mining difficulty tends to follow exchange rate. This phenomenon is universal to other bitcoin forks as well, as we saw some chains had problems recovering from miner withdrawals due to long adjustment intervals. For ppcoin it appears to recover from miner withdrawal reasonably well due to the continuous adjustment design. This type of oscillation has less negative impact on ppcoin network for two reasons. First proof-of-stake block generation is independent of the proof-of-work difficulty. And secondly the proof-of-work mint rate design somewhat dampens the oscillation effect.
Have fun and next week!
Weekly Update #7
Have fun and next week!
- This week the total network money supply surpassed 10 million coins at block 8186.
- Work is under way for v0.3.0.
- Proof-of-work difficulty appears to have bottomed at block 8409, with difficulty 8116. A fairly strong reversal pushed difficulty past 12000 today due to (maybe temporary) strength in exchange rate the last two days. Proof-of-stake difficulty dropped to around 6.
- Andy has added a lot more charts besides the PPC:BTC price chart to his website. Nicely done and now I find myself checking the charts regularly. I like to look at the difficulty chart a lot, it resembles a beautiful mountain range. Looking forward to seeing higher and higher peaks as mining technology progresses.
Have fun and next week!
