Feathercoin 0.8.6.2 Released - Hard fork on block 204,639
-
I thought that the time had shifted a little :)
Glad about that as I have to go to the office for meetings today, and wanted to be here when it happened to see what was going on.
Ahh just remembered another wallet that needs upgrading…

Here’s a direct link for the Zipped Feathercoin.

So 173 blocks to go, that should be about 7.2 hours at 02:30 UTC. Alerts are still ticking on 0.6.4.4 to the 0.8.6 releases and I have sent one last round of messages on social media. I can still see quite a lot of old clients connecting to the network. We’ve even spotted some 0.6.3 clients that stopped being compatible months ago so no idea what those guys are doing on the network. We can expect a fair few support requests tomorrow.
Clients not updated will still subscribe to the autocheckpointing node so they will get told to connect to blocks that are incompatible with the client. There is a chance that after updating they will have database errors. This is the problem we experienced last time with BDB. If this is what gets reported the solution is to stop the client, go to the data directory and delete the blk0001.dat, blkindex.dat, blocks folder and chainstate folder and then start the client again. The blockchain will have to download but the client should work fine at the end.

We’re currently at 6:39 per block, but we’re close to a difficulty adjustment. Block time’s are going to drop soon.

Looking at the block explorer, someone has got a plenty of easy blocks when the difficulty has dropped from 199 to 1.4 in less than half an hour.

There was no special case to take care of the 2.5 minute blocks calculated into the average after the change so were regarded by the new algo as being too hard. We now have enough history under the new algo for things to behave like expected. We have been tested only a little so far, some fast blocks were seen, the difficulty went up, the blocks got a little long and then the difficulty came swiftly down. It will not be long before some of the larger players try to abuse our new solution. This is very interesting to watch.
As long as everything is good with our new solution then we should look toward our new solution post haste.
For those who do not know, Ghostlander is working on his idea called NeoScrypt, the fastest and most efficient version of Scrypt so far that will not be broken by differential analysis for at least a decade it is imagined. I think it is a genius idea like the light bulb, something that seems obvious now but before it took a genius to figure it out :)

I am truly excited in every sense of the word.
This is partially what crypto’s are about.
It’s the grand social experiment of the 21st century. -

I have analysed the preliminary results from the hard fork change over in greater detail.
Handling the change over to one minute transaction blocks took about 130 blocks. Between 13:18am and 13:35am or about 15 mins. 25th/04/2014. By 02:00 the block transaction time had settled to 1 minute for 60 block average. The block times are still settling down as it come fully in.
If any other coins attempt such a change over I would recommend including a period where both cases apply. In this case, for say the first 200 blocks, the data for calculating the new difficulty should have been based on a special case of old look back times (2.30min) divided by the 2.5 to convert old data look back times to 1min equivalents.
This would mean the Block time would have moved gradually move from one value to another. Our change over was a bit sudden.
That’s also a lot of extra software programming and testing for a once only event, so more to go wrong and all miners at the time benefited from the lower difficulty so it wasn’t “unfair” to any one particular interest.
Considering the severity of the swerve, I’m very relieved to see we’re still on the road.
Well done team!

Unless the two profitability calculators I tried are wrong, I am slated to get less FTC per day mining than I was before the hard fork :-/

The statistics calculations are probably are wrong, and will need a slight tweak, due to the block transaction time change.
Wellenreiter did some updates for p2pool. Even so the graphs on that pool are per block, so they show the proportional value of a block.
The transaction time as gone down so you will be paid smaller amounts but more often.
You should get the same payment per 2.5 mins, if not more, as the dust settles from the hard fork…

More than 3 weeks after the fork , could we please have an(y) update (at all) on the next fork for the hash algo change? Bush hasn’t been very vocal lately.

What algos are being considered? CoinDesk released an article yesterday with a few lines about X11, here is the relevant excerpt:
The Rise of X11:
In recent months, innovations have come out of the altcoin community that have pushed new mining approaches and algorithms into the fore. From Scrypt-N to Groestl, more advanced systems for veryifing transactions within the coin network are reshaping the altcoin landscape.
According to a created by pool operator SuchPool.pw, X11 provides a very efficient way to mine coins. The algorithm does not pose the same power needs as other proof-of-work digital currencies, results in lower heat ranges and and greater hardware longevity as a result.
Pioneered by darkcoin, X11 has slowly gained traction in terms of new coin implementation. Darkcoin, along with Hirocoin and québecoin, are perhaps the most notable examples of X11 coins. Additionally, the algorithm has been integrated by some elements of the multipool community, with several pools offering X11 as a mining option.
For altcoin miners, X11 presents an interesting alternative that could become more prominent within the ecosystem. Those hoping to increase the lifetime of their mining rigs may want to consider this new algorithm as a viable option.

We have NeoScrypt coming in soon…
