Post Re: Warning: OpenSSL Consensus Bug
Can anyone provide stats on what fraction of v3 blocks are being orphaned in past 24 hours due to building on v1 blocks?

@Cassini, you should be able to notice once F2Pool activated the nuke when only version 3 blocks show up, right?

Last 100 blocks (242409 to 242508):
Code:
74 DiscusFish V3
10 slush V3
13 eligius V3
3  bitminter V3

Last 1000 blocks (241509 to 242508):
Code:
0   DiscusFish V1
684 DiscusFish V3

0   slush V1
101 slush V3

96  eligius V1
43  eligius V3

15  bitminter V1
3   bitminter V3

43  unknown(ghash.io?) V1
0   unknown(ghash.io?) V3

8   EclipseMC V1
0   EclipseMC V3

0   mmpool V1
1   mmpool V3

6   mined by unknown miners

By the way, the last V1 block was block 242312, mined by unknown(ghash.io?).


From this it looks like at most 6% of hashpower has not yet updated. So my guess is: 6% of the blocks from these miners get orphaned.

ghash.io/CEX told me they have updated. Orphans of pools to the standard version should now be less than 2%. It was a rough ride but for now things look ok. :mrgreen:

It still is. The last 18 blocks as follows:

Awesome. Thanks for the great work guys. Looks like we'll get through this mostly unscathed, without too much disruption for end users.

Another 100 blocks have arrived, 242609 to 242708:

64 DiscusFish V3
12 eligius V3
12 slush V3
7 ghash.io V3
4 bitminter V3
1 EclipseMC V3

Looks pretty good. No orphans during the last 100 blocks as far as I can tell.
EclipseMC already mining V3 blocks.
The hashrate graph shows only a small dent during the last few days:

A majority of Namecoin hashrate is going to begin enforcing BIP66 circa Monday (2015-08-03). This means that all mining pools who don't want their blocks rejected after Monday MUST upgrade to Namecoin Core. Either 32-bit or 64-bit will be fine after BIP66 begins enforcement. (Before that point, we still recommend 32-bit). We apologize for the short notice here.

Do not trust transactions until further notice. Do not purchase new names until further notice. If you have a name that is expiring very soon assume that transactions may be delayed unexpectedly, so renewing those names before the last minute is advisable.
If all goes well things will be mostly working again from Tuesday on (2015-08-04) but you will need to wait for six confirmations (more for important transactions).

(edited as per Biolizard89's suggestions)



1. Links above are "quoted", but from where?

2. Three weeks later, the home page still tells people to use the old version (http://namecoin.info/?p=download). I assume everyone remembers there's a download link on the home page, so why is that link still there?

Can this transition be a bit better managed?

This is certainly a good point. The website is undergoing a transition, and redoing the download page completely is on the to-do list. For the record, now that BIP66 is enforced by all miners, the only people who absolutely need to be using Namecoin Core are the miners. End users can keep using 0.3.80 for the moment, as long as they wait for confirmations. Namecoin Core will be more secure than 0.3.80 since it won't need to wait for as many confirmations, but it doesn't have an integrated name management GUI, which is a problem for some users.

I'm not sure what you mean by "links above are 'quoted'", can you rephrase?

Maybe somename is asking where the binaries we posted came from (i.e. who built them), not realizing that (in the case of the Linux binaries) because of the reproducible builds, who actually provided the binary is not significant. And I guess it isn't apparent that Phelix built the Windows version just because he was the one that made the forum post about it.

Ah, ok. For the record, the Linux binary was reproduced by Joseph, Luke-Jr, and midnightmagic. Phelix built the Windows version using EasyWinBuilder (it was not built reproducibly). I would not recommend using the EasyWinBuilder binary for anything critical (we'll try to get Gitian Windows and OSX builds out sometime). The Linux binary is safe to use, and is being used by a significant number of miners.
