Feathercoin 0.8.6.2 Released - Hard fork on block 204,639
-
Feathercoin 0.8.6.2 is now released and is available to download from the front page of this website. The changes are already live on GitHub in the master-0.8 default repository. This update is mandatory and involves a hard fork on block 204,639 which will happen roughly at 12:00GMT on the 24th April. The new release uses the latest version of OpenSSL so has the fix against the Heartbleed vulnerability. This vulnerability will only affect those who use the rpcssl command line option. It also affects the request payment feature in the Bitcoin 0.9 Qt client but this feature is currently disabled in Feathercoin.
The aim of the new version is to limit the effect of multipools, they are currently mining Feathercoin in such a way that leaves no room at all for people who want to solely mine us. Our last effort to fix this issue worked for a while but the multipools figured out a way to use the last change against us and manage to mine us without moving the difficulty as much as they should but leave the difficulty higher overall. Considering this Wrapper and Wellenreiter have put months into analyzing our current difficulty and multipools including how they mine other coins, not just us.
Wrapper and Wellenreiter have made simulations to see the effect of multipools on us and can see how bad their impact on us is.They have also been able to use these simulations to work out the best possible defense against these pools. After months of analysis the best possible solution was chosen and we have spent the last month running this on the testnet in various forms to gather as much data as possible. The testnet showed that the changes performed exactly as the simulations predicted and that the difficulty closely follows the network hashrate. This is a sign of quality in the simulations that were created, we have powerful tools for developing Feathercoin.
After block 204,639 the following changes will come into effect.
- Block time reduced to 1 minute. We handle more transactions and reduce the window for double spend.
- Block reward is reduced to 80 coins a block to maintain the same inflation model. 80 coins * 2.5 minutes = 200 coins
- Retarget every block compared to every 126 block currently
- Use combined average from 15, 120 and 480 block averages with .25 damping
The new Mac client has been built with QR code support.
EDIT: This release was 0.8.6.1 and as now been updated to 0.8.6.2 which provides a fix for the full chain sync issue reported by several users.

The other thing is to make sure there is support for any changes Any help keeping an eye on the “Support thread” would be great. While we work through any release issues.
xonar, Can you post what AVG free says in the support section? and help us diagnose your fault…

Is there a wget link I could use to update my p2pool server with the new 0.8.6.1 Linux Binary?
-
I have the new Feathercoin up and running. Synking right fine, albeit the blockchain is the one from the old wallet…
Thx guys for the timely release!

Installing Fresh .0.8.6.1 on pc and getting stuck on block 33,582?
Have reinstalled twice today but keeps stoping at this block and will not go further any ideas?
Thanks
Same problem as others - stuck at block 33,582
I have done all the usual tricks to get it moving and all have failed. I have asked my Feathercoin group and everyone that re-installed the client is stuck here as well.

Do you sure that feathercoind need to reinstall ? FTC pool must git and compile code again ?

There seems to be a problem with the links on the homepage.
Until this is fixed you can find the pre-compiled Linux binaries here:
http://software.opensuse.org/package/feathercoin
There are binaries for several Linux distributions, not just Opensuse ones on this server

Only binaries available for Linux?
I was pulling from the git repo but I’m getting the 0.8.6.0-beta. Where are the sources for the 0.8.6.2?
Thx
