Feathercoin 0.8.7.0 released
The NeoSrypt UpdateIt has been a long time in the works but we have finally got NeoScrypt and a GPU miner so we can now release the Feathercoin 0.8.7.0 client with NeoScrypt set to replace Scrypt on block 432,000, this should happen on the 26th October 2014. There is a Twitter countdown to the hard fork available here.
NeoScrypt uses stronger components than the Scrypt we are familiar with. A key element of Scrypt is Salsa which adds memory complexity, the problem is that the version of Salsa in Scrypt is weak and has been broken by differential analysis which is why we see cheap and powerful ASICs. NeoScrypt uses a blend of Salsa and its successor Chacha set to a higher level of strength. In theory these two should not be broken for at least a decade, this gives better protection than simply adding hashing functions.
However the goal is not simply to avoid ASICs forever as this may not be possible though ideally we want to stay in reach of as many people as possible without the need for expensive mining equipment. As the majority of people buying Scrypt ASICs are not doing so to mine Feathercoin and the fact that some very large ASIC suppliers will be releasing products soon it seems sensible to move algorithm now before we face the challenges that hit many SHA-256 alts when the SHA-256 ASICs hit. We are moving to a new tier of hashing where Feathercoin can be the leading coin.
Please be aware that after the update your Scrypt mining setup will no longer work. You will need to use the new GPU miner that we have been developing for several months now. Not only do miners need to upgrade their software but pools do as well.

Fantastic news thanks bush.
Gotta start the count down to the 24th :) -
Thank you Bushstar. I hope you will fully recover from your disease soon.
-
Looking good everyone! Where almost there!
-
Awesome!
-
Hurray!!
-
Brilliant
-
Thank you Bushstar. I hope you will fully recover from your disease soon.
For anyone that’s wondering I got something flu like that totally kicked my ass which was then followed up by a stomach bug just when I was recovering. It has been a rough month but I’m finally back and on form.
Time to add the CPU and GPU miner binaries as downloads to this post, the GPU miner needs to be compiled first which is my first mission of the day.
-
Cool work Bush - glad to hear you are feeling better.
-
I have now posted this over on BitcoinTalk. A bump now and then would be useful to make sure that people see it.

Has cryptsy updated?
Is anyone notifying pools?
-
List in the team section of who has been notified, don’t think Cryptsy has been officially notified yet, but they are on the list
-
Awesome work Bush!
-
great work guys!
-
What does the feathercoin.conf look like for solo mining now?
_server=1 _
_rpcuser=*my_user_name* _
rpcpassword=*my_password*
_rpcallowip=127.0.0.1 _
rpcport=9337
port=9336Is that correct? Cheers!
I think that looks right to me but remember we are still using scrypt until block 432,000.

pool.ftc-c.com had supported neoscrypt , Now you can mine PXC and FTC-t.
-
How to use LOCK/UNLOCK wallet Menu on 0.8.7 , who can give me a guide ? :-[
-
thanks for update :) I hope that neoscrypt will really help to FTC
-
great work guys !
just a little announce on the website here:

Coinotron will be switched to neoscrypt mining on block 43200
