Feathercoin Fork
-
There seems to be some disagreement between different versions of the Feathercoin wallet. It may be sensible to downgrade to the 0.9.3 client but 0.11 wallet.dat files are not compatible, you would need to export private keys from 0.11 and import them into 0.9 to downgrade. The following has been reported to me and I am trying to contact the Feathercoin team with this information.
0.11.2 are not able to process block 1114311

Hope you can find a solution quickly.

It was reported by us (https://give-me-coins.com). I suspect that all the remaining pools need to downgrade to 0.9.3. At least until 0.11.2 is patched.
-
Exactly that’s needed to to.
Upgrade/downgrade to 0.9.3.Versions 0.8.7 and 0.11.2 are stuck at block 111410
Version 0.8.7.1 may work, but we have no proof if it is working or not, so the saffest way it to go to the latest release version, which is 0.9.3 -
@Wellenreiter Can someone walk me through this please so i don’t mess anything up. My technical knowledge is very basic. I’m on 8.7.1 and I cannot sync. I’m also on a mac. How do I upgrade? Should i upgrade? Thanks so much!

I dont know for sure about a mac, but I would think you can just replace the featercoin-qt file with the upgraded version.
-
@AmDD Thanks, sounds easy enough. Im just a little freaked out to do it. Anybody know for sure?..I also did a backup from the wallet and I’m backing up my entire hard drive.
-
@bsotnikow You should upgrade as fast as possible.
Unfortunatelly I’m no familiar with Mac so I can’t help very much
What you should do in principle:
-
backup you private keys
- first option:
- min your 0.8.7 wallet go to help-> debug->console window
- enter dumpprivkey “feathercoinaddress” for all of your addresses
- write down or copy/paste the provate key returned to a safe place
- second option:
- copy your wallet.dat file in the %appdata% directory (windows terminology, sorry) to a safe place
- first option:
-
download and install 0.9.3. For mac it is just the binary.
- restore your private keys
- open console window and enter importprivkey “feathercoinprivkey” for all of your noted private keys
- For the last one add ‘rescan’ at the end of the line
- or copy the saved wallet .dat back to %appdata%
- open console window and enter importprivkey “feathercoinprivkey” for all of your noted private keys
- restore your private keys
-
restart your wallet and let it sync
I hope that someone more familiar with Mac can give a more detailed description what to do

If you make a good wallet backup then you should be fine. Just install the 0.9.3 over the old version and if it doesnt display your FTC, shut down the wallet and replace your wallet.dat with the one you backed up and then open the wallet again.
-
@AmDD Thanks to you both. I’ll give it a go once the hard drive has backed up too, I want to be extra sure.
-
There is currently no Mac 0.9.3 wallet available, we are currently working on it but it may take some time
-
@all What makes you think v0.9.3 is correct while v0.8.7 and v0.11.2 are not?

good question!
-
@ghostlander
more or less because 0.9.3 is up to date with blocks, while 0.11.X is stuck at a block with time stamp 2016-03-04 01:18:53 -
What’s the current version of the ACP master?
-
good question
it’s on 0.8.7
I just got the login
will upgrade now -
Restart your v0.8.7 or v0.11.2 or whatever clients with -disablesafemode to get past block 1114310:

}BTW, I think it’s a nonsense to disable RPC in safe mode.

If most pools and exchanges follow v0.8.7 and v0.11.2, maybe it’s better to follow this fork and investigate incompatibility with v0.9.x. When BTC forked in 2013 due to differences between LevelDB (v0.8) and BerkeleyDB (v0.7 and earlier), they reverted to the v0.7 chain.
-
I’ve got my 0.8.7 node back up
-
@uncle_muddy Thanks. OK. Is it best I just wait, don’t open it and worry about it when its resolved? Or should I try disablesafemode? . . .I would need someone to walk me through exactly how to do that.
