Yes the latest chain async is the same issue we experienced with the version before. Investigation will surely need 1-2 more days. Anyway we are quite optimistic and sure that this issue is the only major bug in the software since we did not faced any other problems since many days. The chain itself does not get "really" asynchron. Only the hash value of the block is invalid somehow. The block's content is the same on every node.
Initially we thought it's a problem with a caching stage for hashing stuff. Then it turns out now with 0.59.4 it's not the case unfortunately.
The mining process also does not create any problems.
Since everything else seems to work fine and even the "chain async" only leads to different hashes but not to different block content the problem itself could be considered to be a small one (general syncing and building works). I'm quite sure that we would have to change only a few lines of code.
I'm flying to a foreign country this weekend, however, we (including myself) will continue to work to bug this out. But I might not answer 1-3 days.
There will be a final beta test once we finished the issue and we integrated something more. So 0.6 will be the next version and the launch version and it will be open beta tested for something like two days before the launch. Assuming we manage to bug this out until 31th and can integrate some missing stuff until 3rd (2 guards against attackers + finalize proxy software against DDoS + minor things like addressbook) then starting the final test on late 4th or 5th we could have the launch on 6th or 7th June. Please don't nail it down to this date but it is a realistic timeline. All depends on how fast we can fix the issue.
I am really sorry for any delay. I just want to emphasize again: It is simply really hard to estimate the needed time for developing software. A troublesome bug can take days to get fixed and cannot be forecasted. Besides, the reallife job sometimes causes much work (normally: milestone work in projects so there are times with less work and times with much work even for the evening/nights) and the daily life also must have a place to exist. So there are many factors which caused unexpected delays and hard-to-tell timelines. Many of you have told us to take the time we need and that it is ok, but there are also many people who cannot understand the delays over delays. I ask you for a bit more patience - and we won't launch with a partially buggy client - thank you ;-) Also, yes, it is right, we could have made more marketing so far. We do not have the manpower to do it properly, but we will have more time for that after 0.6 is out. It is early enough to create more buzz around exo after everything is launched. And: any article about eXocoin (well - positive ones are preferred) help to increase the attention of eXocoin. Many celebs use negative buzz to increase attention successfully
The wiki content will be updated after finishing 0.6. The logo vote can start on 1st June or similar.
