block.version=1 blocks will all be orphaned soon

[eleuthria]

Has anything interesting happend on TestNet as a result of this change?

I discovered the change on TestNet when first designing my custom pool code (before Stratum was announced).  At that time, Testnet had started requiring V2 blocks, and all my V1 blocks were rejected.  So it behaved as expected as far as I could tell.

Blockorigin has been fixed too.  So we're now still at 16.90% v1 blocks...

I do like your site kinlo.

This has puzzled me for a while though, the block counts don't usually add to 1000, and hence the percentages don't add to 100. For example now:
"only the last 1000 blocks are used. We are currently at 162 out of the latest 1000 blocks on version 1 (16.20%) and 822 out of the latest 1000 blocks on version 2 (82.20%)"

I assume that it is because the balance are orphan blocks?

Deepbit has switched over tonight but as eleuthria points out we will still be short of the 95% supermajority.

Well this is unexpected.  Looks like either I'll have to kill getwork this weekend with Ozcoin, or find a way to get PoolServerJ to work with v2 at that time.  I do not want to be the one holding back this change.

Some blocks are not identified as v1 or v2, so they are not counted at all  Not that many tough, I'll investigate why.

BTC Guild has potentially hotfixed v2 support into getwork servers.  It's running on the primary getwork server now after successful testnet blocks.  If it does work, we should see supermajority on V2 very soon now that Deepbit has also started moving to v2 and ozcoin is disabling getwork entirely.

[slush]

Two days ago I fixed my getwork backend to produce v2 blocks.

[eleuthria]

BTC Guild confirmed at making v2 blocks on getwork successfully.  All servers should be updated now, but a little nervous that I may have missed one or not restarted one.  Watching closely, but as of right now I think all of them are now on v2.

Up to 89% now. Not long to go.

There was a new version-1 from ozcoin a short while ago at block     227377

All the other big pools seem to be producing v2 now.

Ozcoin is going to shutdown their getwork servers today.  This means that *after* today they won't produce v1's anymore, but today they still might...

Coinlabs and BTC Warp are the only pools with no recent V2 block.
Hopefully they are looking at v0.8.1 now...

They will have to if they want to mine valid blocks.  It seems now it's just a matter of time before that 95% threshold is met.  The variance should make the probability of hitting it in the next 5000 or so blocks very high.

About to hit 91%. I think we will hit the v2 within the week.

[Graet]

Ozcoin has shutdown ecoinpool and setup stratum proxy for getwork miners to continue and create v2 blocks

So long and thanks for all the bitcoin Deepbit?

I am missing something, is deepbit not compatible with the updates?

Please fill me in!

It is now When that post was made it wasn't compatible.

Deepbit updated to v2
coinlabs and  btcwarp are the only vulnerable pools now

FYI, as of 227743, counting v1 blocks backwards puts the 50th version=1 block at about 226930.

That means, at 227930 (assuming no more v=1 blocks), there will be 950 of the last 1000 and a 95% supermajority.

That's roughly 185 blocks from now.  24-30 hours.  It should be all over in time for breakfast in the US on Monday morning.

Of course, there's probably going to be 5-10 more v1 blocks so I'm guestimating 227940.

Edit: 24-30 hours is wishful thinking given the spike in hash rate.  Probably < 24 hours now.

Thanks for doing this analysis!

Just before 1pm EST: We are currently at 62 out of the latest 1000 blocks on version 1 (6.20%) and 938 out of the latest 1000 blocks on version 2 (93.80%)
