Great work guys, can't say how grateful I am for the work you're doing. I have a question though: Zero-confirmation transaction vulnerability: accepting zero-confirmation transactions (transactions that have not yet been included in a block) from somebody you do not trust is still not recommended, because there will always be ways for attackers to double-spend zero-confirmation transactions. However, this release includes a bug fix that makes it a little bit more difficult for attackers to double-spend a certain type ("lockTime in the future") of zero-confirmation transaction.
I assume this means only transactions sent from 0.8.0? So that an attacker can just keep using the older version for his purposes, regardless of if the receiver has the latest version. Not saying that it still isn't a very important fix to have for the future. Also, yesterday I saw some very quick confirmations on a lot of transactions, even no-fee transactions were generally confirmed in less than 10 minutes, which is very good for business. Does that have something to do with this update or is it just a coincidence?

What are all the sst files for? Also you might want to post what can be cleaned up after the install since the install does not do it. Also during install it would be nice if you could let the user specify the datadir rather than using a command line flag.

Just a coincidence. ASIC miners are rapidly coming online, which increases block production until difficulty changes to compensate.

What can I safely delete? I highlighted in bold and color what I think can be deleted. Can someone confirm this?
You can safely delete those that you highlighted. As the new files is in the "blocks" directory. Easiest way for you to check is to close the bitcoin client, move those files to another directory and then start the client again and check if it starts downloading the blockchain again.

Too bad bitcoin-qt can't use your GPU to accelerate re-indexing the block chain. It's already using multiple CPU cores if they're available.

You are in a maze of twisty little passages, all alike.

Reindexing helps me getting closer to the end of the chain. But it's slow as hell ![Cry](https://bitcointalk.org/Smileys/default/cry.gif) One step forward, two steps back. Edit: going back to 0.7.2. Hope future releases take care of this problem.

Re-indexing the block chain is unusually intensive. If there are minor faults being introduced by your HDD then most apps probably wouldn't detect them for a long time but Bitcoin is very sensitive to it. If it's not hardware related why are you seeing signature check failures (can only be caused by bad hardware, pretty much) and other machines are working fine?

I agree with Mike Hearn that this is likely the cause. The PC I had this problem with is a 5 year old laptop which just might be breaking down slowly but surely. It's not a problematic PC otherwise but I guess LevelDB is intensive enough to be problematic if there is even a small flaw with the HD. Maybe I need a new laptop. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

I agree with Mike Hearn that this is likely the cause. The PC I had this problem with is a 5 year old laptop which just might be breaking down slowly but surely. It's not a problematic PC otherwise but I guess LevelDB is intensive enough to be problematic if there is even a small flaw with the HD. Maybe I need a new laptop. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Or take it apart and clean out five years worth of lint and fuzz and put new thermal compound on the CPU cooler: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fwww.logonfixit.com%2Fimages%2Flaptop_vent%2Finside_view.jpg&t=665&c=QL_fbxWm6KFULQ)

I'm running Ubuntu 12.04, all upgrades applied, in a VirtualBox. Almost all networking is IPv6. The VirtualBox has 512 MB (<--small, I know) RAM. The host machine is a dell Optiplex GX620, XP-SP3, 4 GB ram, 3.00 GHz pentium 4
I created a new virtual machine, created a disk specifically for bitcoin, and mounted it on ~/.bitcoin. I used ssh to copy the ~/.bitcoin directory over from the 0.7 installation.
My bitcoin.conf file includes connect=<my 0.7 installation address> onlynet=IPv6 logtimestamps=1 server=1
At startup, 0.8 seemed to index about 10-15 blocks / second. I started it mid-day and the projections were that it would finish by 8PM last night.
At about 6AM this morning, it was still about 2,000 blocks from being indexed. The speed had slowed to about 10-12 seconds / block.
With block 223,261 now onboard and everything current, and after erasing the old blockindex.dat file, du . shows 6,842,184 bytes. This includes some logfiles that include timestamps.
One thing I notice is that the menu (File, Help, & such) does not seem to display if the program is shut down, and then restarted. If the window is maximized, these items show up again.

I try to be respectful and informed.

Congrats on running a 11 month old OS, on a 11 year old OS on a 10 years old computer (P4 3.0GHz release April 2003). There weren't many people trying to use a 1991 computer (pre CD-ROM) in 2001 (post-Google). ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fsphotos-a.xx.fbcdn.net%2Fhphotos-ash3%2F553919_10150909576738222_2001448042_n.jpg&t=665&c=je4R8T7niT7m1Q) Is this progress or a lack of progress?

If the window is maximized, these items show up again. You are not the first to report strangeness with Unity (the bastard pile of MacOS wannabe move-the-menu-to-the-top bs that Ubuntu slapped on Gnome in order to keep up with Windows 8 in the stupidifying of GUIs). There is an official issue here: https://github.com/bitcoin/bitcoin/issues/1242 where you can add your steps to replicate on 0.8.0. The workaround is sudo apt-get install kubuntu-desktop.
