Another nightly build for win32 is available

Another nightly build for win32 is available.

Changes list:

  • Randomization of NTP sampling interval. Instead of static delay, current implementation of NTP client is choosing a random delay between 1 and 6 minutes in case of error or 1-6 hours in case of successful synchronization.
  • GetAdjustedTime() function uses p2p offset correctly if amount of NTP offset samples is unsufficient.
  • Additional NTP servers were added, new amount of servers is 162.
  • getinfo RPC call now provides you additional data about your system clock offset against NTP and the p2p median time.
  • Some irrelevant changes in the proof-of-stake miner.

Support for automatic time sampling over NTP

Support for automatic time sampling over NTP has been added into main sources tree. Now client tries to check whether there is ntpd running on current machine. And if it’s not, creates a time sampling thread in order to maintain better accuracy of timestamps which are given by GetAdjustedTime() function.

Now client supports automatic selection of optimal source of time between NTP, median of p2p clocks and system time.

New libraries

Few weeks ago Balthazar have published a simple client implementation of Stratum protocol.

https://github.com/CryptoManiac/StratumLibrary

Currently working on pure C# implementation of basic NVC protocol features.

https://github.com/CryptoManiac/NovacoinLibrary

While libraries are far from being complete, this code already may be useful for block or transaction parsing, generation of addresses etc. The goal is to implement a minimum which is required to create our own implementation of Electrum client.

New build 0.4.4.6u4

NovaCoin client update 0.4.4.6 u4 has been published.

It’s the mandatory update which should be applied before 20 Aug 2014. Database format is compatible with recent 0.4.4.6 builds, so you don’t need to re-syncronize the blockchain.
CoinsDB engine isn’t stable enough for now, so I suppose that 0.4.4.7 branch will be frozen for indefinite time. But its experience will be used in the 0.4.4.6 branch.
