Weekly Update #56
Have fun!
- Mikael released hp11 with further xpm miner improvements.
- mtrlt opencl miner released to public testing.
- 13-primes found at block 159217, press release at https://github.com/primecoin/primecoin/wiki/Primecoin-Reaches-13-primes-Milestone
- Sean's outpost, a spirited charity for helping the less fortunate now accepts PPC and XPM donations. Thanks to Jason for the excellent work and good luck to Project Satoshi Forest! http://seansoutpost.com/
Have fun!
Weekly Update #55
Have fun!
- Dan Roseman published a good introduction to primecoin on Let's Talk Bitcoin (http://letstalkbitcoin.com/primecoin-primer/)
- Crypto-trade begins PPC/USD trading.
- Primecoin difficulty remains steady at around 9.86. PPCoin difficulty is now around 1.5M.
- Mikael's XPM charts page at http://muuttuja.org/primecoin-dev/charts/
- PPC v0.4 requires some more time. I expect code to be completed in 1~2 weeks, then followed by a couple more weeks of testing before release.
Have fun!
Weekly Update #54
Have fun!
- mtrlt's xpm gpu miner released for private beta.
- Mikael's high performance client is now linked directly on primecoin home page.
- Primecoin difficulty reaches 9.85, rising steadily throughout the week despite heavy exchange rate drop against BTC.
- PPC v0.4 is still under development. I will give some updates on its progress next week.
- Coin Payments temporarily suspended PPC and XPM support, before a popular request for them to resume support. Coin Payments is the first payment processor supporting multiple cryptocurrencies, even though currently shop selection is still limited, I believe it is important to help such payment processor to grow. So I would encourage both PPC and XPM supporters spend some coins to test purchasing goods and services through Coin Payments. If you have plan of opening stores supporting PPC and XPM, feel free to discuss your plan with Coin Payments, and enable PPC and XPM payments with your coin selection on Coin Payments.
Have fun!
Weekly Update #53
Have fun!
- Mikael released v0.1.2-hp10 with miner improvement.

Weekly Update #51
Have fun!
- Primecoin difficulty rises this week and reaches 9.7, following performance improvements in the new release version hp9 of mikaelh.
- Primecoin records as of this week stand at: 12-primes: 99-digit bi-twin (#111414), 11-primes: 140 digit Cunningham chain of first kind (#95569), 10-primes: 138-digit bi-twin (#85429). There have been now three 12-primes seen in the block chain. At this rate we probably would see the first 13-primes this year.
- mtrlt's opencl miner appears to be close to private beta.
- Crypto Street (a new exchange) is considering adding XPM support.
- Vitalik from Bitcoin Magazine interviewed me on ppcointalk.
Have fun!
Weekly Update #50
Have fun!
- Primecoin v0.1.2 is released. Users can now use the new listprimerecords to check the most up-to-date records inside the network. A new performance metric chainsperday is introduced to help performance tuning.
- mikaelh joins primecoin core dev team. Mikael's work with his high performance releases has been top notch and will share responsibilities with me in future development and maintenance of primecoin. (announcement: https://bitcointalksearch.org/topic/xpm-ann-welcome-mikaelh-to-primecoin-core-development-team-266329)
- mtrlt has made further progress on his opencl miner. (https://bitcointalksearch.org/topic/xpm-working-on-a-gpu-miner-for-primecoin-258540)
- ypool is gaining momentum with peak block rate of the week reaching 25% of the network.
- Primecoin difficulty dropped to 9.2 earlier in the week and has been climbing up steadily.
- DailyBit.net is accepting primecoin payment. (https://bitcointalksearch.org/topic/ann-dailybitnet-now-accepting-primecoin-xpm-267068)
- PPCoin v0.4 development resumes this week. Tentative target release date in early September.
Have fun!
Weekly Update #49
Have fun!
- Primecoin has made a lot of progress in 3 weeks. I am so happy with the level of development support accross the cryptocurrency community. So here I would like to thank all for your hardworking in something we believe is a worthwhile cause!
- Primecoin network has claimed the 10-prime, 11-prime and 12-prime world records in simultaneous primes, on top of the Cunningham chain records and bi-twin chain records we hold. The simultaneous prime records count prime tuplets and arithmetic progressions in addition to prime chains. On this record GIMPS currently holds the 1-prime (single prime) record, while primecoin now holds three!
- On the development front, v0.1.2 release should be ready soon with additional miner improvements and other features. Users of mikaelh's version should continue to watch his builds as I think his build would remain the best performance builds for a while. mikaelh is an excellent developer and has earned the trust of the community. Meanwhile both gpu projects are still under development by mtrlt and primedigger.
- Starting next week I would resume ppcoin v0.4 development. I would make some announcement later on regarding the plan.
- Crypto-Trade now supports XPM/USD and XPM/PPC trading pairs. To have exchange support of direct XPM/PPC trading is part of our strategic goals. Thanks neotrix and team for the support!
- Due to the recent volatility in xpm trading I am obligated to once again remind investors of the high risk associated with cryptocurrency investment. Please invest only what you can afford to lose, thanks!
Have fun!
Weekly Update #48
Have fun!
- Primecoin continues to surprise and this week we saw difficulty broke through 9! On block #74722 primecoin network finds its first prime chain of length 12, another new world record of course. Meanwhile by its second week primecoin has sweeped all length 10 and 11 Cunningham chain and bi-twin chain world records.
- Primecoin also surprised in capital market by reaching 1 million dollar market cap, now supported by 5 exchanges, helping several relatively new exchanges to reach record high trading volumes. On the highest day of the week it reached over 2000 BTC combined volume on the exchanges.
- Highest market cap rank of the week is #5, right behind ppcoin. Currently primecoin ranks at #6 and having a close match with NVC.
- At least two gpu miner projects are under development, one for opencl by mtrlt (https://bitcointalksearch.org/topic/xpm-working-on-a-gpu-miner-for-primecoin-258540) and one for cuda by primedigger (https://bitcointalksearch.org/topic/xpm-cuda-enabled-qt-client-miner-for-primecoins-source-code-inside-wip-258982). mikaelh continues to improve on his optimizations of built-in miners. Meanwhile ypool became the first mining pool of primecoin with its own cpu miner. I am very happy to see the level of mining development for primecoin. Primecoin is designed to sustain a vibrant and competitive mining market.
- Media continues to show interest and praise in primecoin. For example, it is reported by The Register that DigitalOcean was hitting capacity problems after 18000 new registrations for mining primecoin. So now we understand why the block rate was going crazy last weekend. Some media credit primecoin as 'solving the energy waste problem'. To be fair I think ppcoin should be credited as such. ppcoin is designed to be energy efficient, while primecoin is designed to be energy multi-use. They are a two-prong approach to the energy consumption problem of cryptocurrency.
Have fun!
Weekly Update #47
Have fun!
- Primecoin made a big splash in the first week of its debut, with enthusiastic mining participation we managed to break multiple world records including 1CC0a, 2CC09, 2CC0b, TWN0a, and still besting our own records many times. Not only that, the race toward improving miner performance has already begun. Primecoin is designed to sustain a long-term prosperous mining industry, so I look forward to the constant improvement of algorithms and hardware advances by market participants.
- Many people ask about the scientific value of finding these prime chains. I have already delved into this topic in my design paper. The prime chains are believed to have infinite existence for every length, and a distribution law similar to those of prime number theorem. So it is connected to the deeper mysteries of prime distribution, a lineage from the first breakthrough at Riemann's time. Yet for the most simple case - the twin prime conjecture - no one can yet prove their infinite existence (some breakthrough with this earlier this year), let alone the distribution law. Primecoin network would provide further experimental data and spur the research and development of advanced algorithms in searching these chains that may provide possible clues to this phenomenon, in my opinion one of the top wonders of arithmetic.
- Primecoin has been reported by Bitcoin Magazine with 2 excellent technical articles and now supported on 4 exchanges. Our market cap ranking is now right outside top ten looking for a match with DGC and FRC.
- At the weekend peak there were about 1000x mining power in primecoin network compared to the first day of the release, due to a combination of improved miner and heavy growth of mining participation. The network has started cooling down a bit as of now. Difficulty broke through 8 yesterday, currently still marching toward 9 (right now 8.85) but somewhat stabilized.
- On the ppcoin side, the logo project lead by Sentinelrv has been completed and a nice new logo is selected by the community. Congratulations to the team!
Have fun!
Weekly Update #46
Cheers
- Primecoin is released! I am happy to announce the second innovative cryptocurrency design has now joined ppcoin as our advanced technology portfolio in the highly competitive cryptocurrency market. Primecoin design and development took a better part of 4 months since March, I am relieved that it is now released to public. I hope this work would further advance cryptocurrency field and inspire other scientific computing proof-of-work types to emerge.
- In addition to the design effort, I have also put a lot of work into organizing the design paper as well. Hope you all enjoyed it.
- The currency symbol of primecoin is chosen as the greek letter psi. This letter is chosen as a tribute to Riemann, as its shape symbolizes the Riemann zeta function (there is a graphical rendering used in primecoin windows setup screen). The horizontal bar is not only a standard currency symbol convention, but also symbolizes one of the highest jewels of math - Riemann hypothesis.
- Primecoin network now will complement ppcoin network to strengthen our overall competitive position in the market.
- In the next week I will watch primecoin network closely to ensure it is operating as designed.
- Meanwhile this week the ppcoin logo design project lead by Sentinelrv is proceeding to the final design round. Thanks to all who have participated in the design and voting!
Cheers
Weekly Update #45
Have fun!
- Primecoin prerelease: https://bitcointalksearch.org/topic/xpm-ann-primecoin-prerelease-announcement-introducing-prime-proof-of-work-245953
- I am happy to launch another innovative cryptocurrency design soon. Primecoin project was under development since March. It was meant to complement ppcoin in our technology portfolio. Primecoin introduces the first non-hashcash proof-of-work, prime number proof-of-work, the first proof-of-work in cryptocurrency that not only provides minting and security, but also provides additional potential scientific values. This advancement will pave the way for future proof-of-work types with diverse scientific computing values and uses.
- Primecoin is currently tentatively scheduled to be released next week (July 7th). Please visit the prerelease thread for updates.
- Primecoin network would complement ppcoin network to strengthen our strategic position in the highly competitive cryptocurrency market.
- My weekly updates will from now on cover both ppcoin network and primecoin network.
- PPCoin v0.4 development was recently delayed to speed up the primecoin release. Once primecoin release settles, ppcoin v0.4 development would resume and take priority.
- A reasonably good article from Daniel at The Mises Circle: http://themisescircle.org/blog/2013/06/24/the-proof-of-work-concept/
Have fun!
Weekly Update #44
Have fun!
- A new exchange coins-e.com now supports PPC trading.
- Captcha requirement is reduced on the ppcoin.org marketplace (http://ppcoin.org/market) to help users trade, also the rating thread and rating format is now up.
- Several new coins have been added to the marketplace for trading including onecoin and sifcoin, two latest cpu altcoins.
- I see peer-to-peer trading as an important part of cryptocurrency community in the future. As we can see recently, the political environment for the exchange operators are not very amenable. The goal of PPC Marketplace is to experiment in this area and gain some experience for me, while keeping its scope limited so that I can still focus on development and operations.
Have fun!
Weekly Update #43
Have fun!
- Recently a few product/service websites start taking PPC as payment, including fendlestick's coingas, and Petr1fied's cryptoblackjack. Most of these new websites accept multiple cryptocurrencies. I expect this trend to continue as the market starts recognizing the benefit of competition in cryptocurrency.
- New Mercator Advisory Group published an analyst report on alternative currencies which mentioned ppc. http://www.researchandmarkets.com/research/s5f5c3/alternative
- Recently we have seen intermittent 51% attack on feathercoin network and other new cryptocurrency networks. This was one of the top reasons that ppcoin's checkpoint system was originally designed. The recent attack on feathercoin network indicates that the attacker is quite resourceful, controlling maybe upward of 2gh/s scrypt mining (meaning thousands of highend GPUs). The phaseout of ppc's checkpoint is planned for later this year but will be gradual. Eventually the checkpoint would become user enabled and by default not enforced. In this running mode, the checkpoint system still acts as a safety mechanism that can be utilized via community consensus in the event of persistent 51% attack on proof-of-stake or other emergencies.
Have fun!
Weekly Update #42
Have fun!
- A new exchange Crypto Trade (https://www.crypto-trade.com/) now supports PPC trading.
- Please vote for PPC support on mtgox feature request: https://support.mtgox.com/entries/21676064-Please-Add-Peer-2-Peer-Coin-PPC-
- We were mentioned in a Tom's Hardware article (http://www.tomshardware.com/reviews/bitcoin-mining-make-money,3514-9.html). As to the mining market of PPC, D7 now controls the majority of the network hash rate. However unlike pure proof-of-work cryptocurrencies, security is not threatened with 51% attack when a single pool controls a majority of mining power in the PPC network. Also, when the pool runs into technical issues, the network still mainly relies on proof-of-stake blocks so the impact to transaction processing is minimized.
Have fun!
Weekly Update #41
- ppcoin.org marketplace is now live (https://bitcointalksearch.org/topic/ann-ppc-ppc-marketplace-trading-ppc-xpm-224012) with minimum features. This marketplace helps facilitate trading between forum users. It is intended to encourage trading with PPC as currency. We do not intend to run commercial marketplace websites as it's not our area of expertise. In my opinion our development resource is better spent elsewhere. So we look forward to community created auction/retail market websites. This marketplace will serve as a good exercise for us to web-of-trust rating system.
- Not much else to report on this week. So have a fun week!
Weekly Update #40
Have fun!
- A new exchange 'cryptsy' has started ppcoin support.
- Two tip bots currently support ppcoin, first being cointip which can be used on bitcointalk, the other ALTcointip can be used on reddit.
- A market feature will begin trial on ppcoin.org later this week. The client refresh to bitcoin 0.8 is scheduled afterwards for later in June.
Have fun!
Weekly Update #39
Have fun!
- A new exchange 'Coin Market' is in the works that supports PPC.
- Another ppc fork called 'bitgem' launched this week.
- I will introduce a trading section on ppcoin.org to help seed the market in using ppcoin as currency. The scope of the work is limited but it will have some advanced features. It's important work for the longer term in my opinion and it is currently taking higher priority than the next client release.
Have fun!
Weekly Update #38
Have fun!
- A new exchange 'Crypto Street' is in the works and is planning to support ppcoin. Crypto Street will support 5 national currencies at its release. Counting RUR from btc-e and CNY from bter, there would be 7 currencies convertible with PPC on exchanges.
- dreamwatcher (Robert) contributed seednodes and dns for our seednode infrastructure.
- Another PPC fork called Yacoin (YAC) has launched this week. PPC now has 3 forks NVC, BTB and YAC.
- Bitcoin has introduced a default minimum output value, although it does not enforce it in protocol. This action confirms our opinion that block chain is not suitable for micropayments (ppcoin output value must meet 0.01PPC minimum).
- The graphics team continues to put out great designs! I noticed that Arstechnica even included Mjbmonetarymetals's earlier designs for a redub of Wired UK article on altcoins.
- TheSeven did great work for PPC pools, but his own pool is underutilized right now. It has great features with support of 5 different types of payout systems. I hope more of our miners give his pool some help to get it into reasonable hash rate (http://theseven.bounceme.net/~theseven/pool/).
Have fun!
