Solo mining ethereum cryptogram
A brain wallet implementation is still under development and testing. I have updated github repo throughout the week and Fuzzy started publishing some test builds. Primecoin github reaches 9. Setup You need the Qt4 run-time libraries to run Primecoin-Qt. Steemit is now Enterprise Source, meaning anyone can make a Steemit type website enterprise just Copying Primecoin and renaming it, and changing whatever they want to change. Please invest only what you can primecoin to lose, thanks!
Weekly Update Excoin https:. Weekly Update Peercoin 0. No need to upgrade if you don't use this feature. The Amsterdam bitcoin conference this coming week is cancelled due to lack of attendance. Release schedule is now fixed as following: A brief read of the its pre-launch description indicates that the proof-of-work is now a slight variation of Primecoin's proof-of-work, searching for a specific type of prime constellations instead of Cunningham chains. It serves as a template for running crypto ventures or businesses, also known as DAC's.
The biggest limitation of the official Zcash software is enterprise it only takes advantage of your CPU to mine. We do not intend to run github marketplace websites as it's not our area of expertise. Each extension will effectively process an additional set of numbers github the sieve relatively cheaply. I have done another community interview this enterprise, transcript here: The software primecoin capable of data extraction, processing, data modeling and analysis.
Primecoin newsletter 1 published:. The vulnerability has been known to us for a while and I have spent quite some time to formulate an improved hash protocol. Proper review and implementation of the new protocol would take some time, and that's why I stress the importance of responsible disclosure as not all vulnerabilities can be fixed and patched in a day or two.
The schedule of implementing the new protocol is tentatively planned as following: Yes the protocol change would be a hard fork and all clients are required to upgrade within weeks after the release. Merry Christmas to all! December 31, , Weekly Update 19 Total money supply surpassed 15 million coins this week. This week saw the debut of freicoin on the bitcointalk forum actual release was the week before on Dec.
I don't see the benefit of the concept of demurrage except for being more honest than the inflation tax, but alas, with even fellows at the Federal Reserve becoming fans http: Weekly Update 20 Release 0. Given the current progress and to ensure the quality of the protocol upgrade we might extend the testing period by weeks before final release. So that means the release would be around end of January. Our seed nodes infrastructure recently experienced frequent outages.
So for new nodes or nodes trying to redownload block chain you might experience connection issues. Running nodes shouldn't have these problems as those can always connect to other operational peers. I am trying to check the seed node status everyday so generally if you cannot connect as a new node just wait some time and it should be able to. Have a fun week! Weekly Update 21 Release 0. First round of unit testing has been completed.
Over this week testing on testnet is being prepared. Over the next two weeks we plan to migrate the seed nodes. Short periods of down time no connection is possible for new nodes and nodes attempting a redownload of block chain. Existing nodes shouldn't be affected. Due to exchange rate drop proof-of-work difficulty dropped below We remind investors and traders be fully aware of the experimental nature of the project and the volatility in market, and manage risks accordingly.
With ASIC release looming the bitcoin difficulty is expected to rise quickly in the following months. Further volatility of exchange rate is expected due to this. Weekly Update 22 Testing continued with 0. I expect testnet testing on protocol switch to be initiated some time this week, when the core code is considered reasonably stabilized. The transition for users should have minimal impact as there is no effect on existing wallet balance, transactions and minting related protocols of the network.
The new protocol replaces the current proof-of-stake difficulty in the role of stake modifier inside the proof-of-stake hashing computation not to be confused with proof-of-work hashing, which remains unchanged. The stake modifier is a part of the hash inputs to scramble the computation so nodes cannot compute the future stake from a coin when the coin is first confirmed into block chain.
The new protocol generates the stake modifier from roughly 10 days of future blocks from when the coin is first confirmed into block chain. This should reasonably resolve all currently known vulnerabilities regarding stake generation. Due to the technical nature of implementing and switching a core part of the protocol, we feel it's prudent to thoroughly test it before 0. Meanwhile, I am also contemplating releasing an unpolished gui build with 0. Weekly Update 23 0. Testing continues on the release and I have just started testing with testnet protocol switch.
The hosting provider for our seed nodes infrastructure is undergoing some migration pain and the recent support has been less than stellar. I would need to look for alternative providers next week preferrably accepting bitcoin, recommendations are welcome. Meanwhile some downtime is expected over next few weeks, for new nodes and nodes redownloading the block chain. Existing running nodes shouldn't be affected.
If I manage to still have some extra time I might start looking into qt build for the release. Weekly Update 24 The seed nodes have been successfully migrated this week. The new servers have been running smoothly the last couple days.
Also thanks for Andy and xchrix for volunteering their nodes. Hopefully the seed nodes would now have better availability for block chain download.
Testnet has been successfully switched to the new v0. The new code looks to have stabilized and I will continue testing on test network this week. I will also test building qt client in our official build for possible inclusion in the 0. The official build of ppcoin adopts bitcoin's verifiable build system gitian-builder. This system allows developers to verify the integrity of the final release binaries.
In theory users can verify the build too by following the same build procedures but currently the process is quite involved. This is part of the reasons why we haven't supported qt in release build yet. We believe that delivering trustable executable files is very important to our users.
The first ASIC miner has been delivered on the market. Another milestone in the young history of bitcoin and cryptocurrency. Weekly Update 25 Testing of 0. System has stabilized and no significant issues have been found this week. Windows Qt build testing is successful this week, and works have been done so it is now confirmed that Qt begins support in 0.
Current plan is to have a final week of testing. Barring further issues, v0. Weekly Update 26 v0. Qt UI begins support in v0. Release is expected to be published in the next few days. This is a mandatory upgrade release and deadline for upgrade is scheduled for March 20th.
This week the first ppcoin fork known as novacoin has been released. The network hash rate of novacoin rose quickly, it's difficulty peaked over Despite the controversy surrounding its release and the subsequent DDoS attack on btc-e, market response seems quite enthusiastic. Please note I am not involved in novacoin in any way, but I am happy to see other developers valuing ppcoin design and forking from it. Recently we have also seen another project known as ripple released, with its own currency called 'Ripple' or XRP.
Even though I am yet to be convinced that the technicals are sound I will keep an eye on this interesting new development. Weekly Update 27 v0. Upgrade should be performed before protocol switch on March 20th.
A block chain re-download is necessary for the upgrade. The blocks are grouped and 64 blocks are selected based on a 'selection hash'. Then each selected block contributes one bit to the modifier.
The purpose of stake modifier is to prevent stake owner from manipulating future stake generation at the time the coin is confirmed into block chain. Two other protocol changes are made: Overall I think the 0. Qt UI is now available in official build and supported from v0.
User who prefers UI would enjoy the release I think, and I did give you a good treat by making the splash artwork myself and hope you all like it v0. An RPC command 'sendtoidentity' would allow users to send ppcoins to names instead of addresses.
