So if I keep minting on the wrong fork, the worst case scenario would be that I would lose 2 weeks worth of block reward? That is not nearly as bad as the case with peercoin where I have withdrawn tons of coins from BTC-E during the past couple of months. If BTC-E was on a wrong fork I have probably lost everything and there is not much I can do, right?
The worst case scenario for you individually is if you buy coins from someone on the un-updated fork after an attack has occurred. From a shareholder perspective, in the event of a fork the difficulty for the correct fork will drop drastically and it is better to have as many shareholders on the right fork as possible. Still, you are right that the most important thing is that the exchanges upgrade.
Compiling from source (nud and bcexchanged) on RaPi worked flawless. But interestingly the stripped nud has exactly the same size as the old one. I had to compare checksums to of nud-2.0.1 and nud-2.0.2 to find the difference

the attack occurred on 9/11 ! holly moly, now i see the date!
i lost 3 days of PPC minting only. it could be worst 
OSX builds are compiling right now. Iāll post them as soon as they are signed.

Iām out of time right now, so I havenāt had a chance to move it to the wallet download section of nubits.com site yet, but hereās Nu 2.0.2 for OSX (Qt) linked from the Nu repository:
Nu 2.0.2 for OSX
sha256: 9a35f380d3af361aaf99cfc568774877040d5e4aabbbdfaf3f86ebbb5e8ef9a8
B&C Exchange for OSX ā Compiled, but Iām holding it back until a follow-up test can be run. I had an issue initially starting it up (required that I clear out my block index before restarting it without an issue). Unclear as to why it threw the error initially so I want to be sure itās safe for public consumption before I release it. Apologies for the delay.

Updating my rpi minting machineā¦ Will update the unoffical build for rpi asap
I canāt compile a working bcexchanged on my RPI 2.
pi@xxx:~/nu/bcex/src/src$ ./bcexchanged --datadir=/xxx/.bcexchange
B&C Exchange server starting
pi@xxx:~/nu/bcex/src/src$ bcexchanged: kernel.cpp:475: unsigned int GetStakeModifierChecksum(const CBlockIndex*): Assertion `pindex->pprev || pindex->GetBlockHash() == hashGenesisBlock' failed.
I can provide a dump file of the make process over pm if required.
After I compiled 3.0.1 I didnāt delete any files in the datadir and bcexchanged started right away.
Did you compile 3.0.0 on the same machine?
Or did you use an unofficial build, maybe @desreverās?
@desrever can you confirm that the unofficial nud build for ARM uses BerkeleyDB 5.1?
If you compiled both versions yourself - with what BerkeleyDB version did you compile 3.0.0 and 3.0.1?
Iāve made both with 4.8, but donāt know whether that can have to do with this error message.
both 3.0.0 and 3.0.1 on the same Pi. No berkely updates.
Iām still not sure whether that has to do with BerkeleyDB, butā¦
Did you export the libdb path before compiling?
Typical path would be:
export BDB_INCLUDE_PATH="/usr/local/BerkeleyDB.4.8/include"
export BDB_LIB_PATH="/usr/local/BerkeleyDB.4.8/lib"
They symlinks are available after a restart, but I think the exports arenāt.
You know https://docs.nubits.com/nu-raspberry-minting/, right (thereās a BerkeleyDB section)?
Maybe I bark up the wrong treeā¦
Nud unofficial for raspberry pi compiled and pushed to github
get with
$ sudo wget https://github.com/desrever-nu/nu-raspberry-unofficial/raw/master/latest/nud
and
$ sudo mv nud /usr/bin/nud && sudo chmod a+x /usr/bin/nud
Can you build one for bcex as well please? 
File corruption related, https://bitbucket.org/JordanLeePeershares/nubit/issues/221/assertion-pindex-pprev-pindex-getblockhash
You will have to re-download the blockchain. The binary is fine.
Iāll try that, thank you.
Is there a trusted nud 2.0.2 for OS X compiled? Iād appreciate someone pointing me in the right direction for how to compile one otherwise. Would a previous nud work as well when the intention is for FLOT usage? I would still need to acquire it somehow.
Scroll upā¦[quote=āBen, post:27, topic:3022ā]

Thatās only the GUI application unless I missed nud somewhere.
