first neoscrypt block mined
successfuly switch to neoscrypt

Dev said via pm that the diff was supposed to reset.

But I'm throwing about 120 kh/s at it via gpu, so if that is the issue, I'll hit it eventually..

cryptominingpool is still scrypt

p2pool wont connect, solo mining wont work

cryptominingpool, not accepting any shares

The pow is neoscrypt but the diff hasn't been reset. (switch pow @ block 65999 & diff reset @ 66000) IMO.

It apparently did not..  

The wallets report still block 65999, yet the neoscrypt mining software is reporting rejected blocks about every 5 minutes, while no "new block detected on network"..

i have a feeling everything did not go fine this time..

D-day...

About 1 hour to switchover..

Here is a pool that is already setup for mining IPC using the Neoscrypt Algorithm.

FYI, we have 133 blocks more to go before the changeover.

New updated wallets for Linux.....

   Linux (64 bit Ubuntu): http://www.imperialcoin.org/wallet/linux/IPC-ubuntu-14.04-x86_64.zip

We only have 530 blocks to go until ImperialCoin (IPC) switches over to the Neoscrypt algorithm. Please update your wallets ASAP.

Thanks for your support.  By our calculations, the switchover to the new Neoscrypt algorithm will occur in about 3.6 days from now or late Tuesday (EST).  At this time, we have updated our seed nodes, the block explorer (http://blockexperts.com/ipc), the website and notified all the pools and exchanges. They will all get reminders from us in a few days if we have not heard from them.  We will be working to get Linux and Apple wallets for you this weekend.

In regards to mining IPC, we have seen some recent spikes in hash rate - most likely with ASICs trying to get the most out of them before the changeover.  After the switch, you will need to use the CPU miner mining software specially modified for Neoscrypt or a new beta version mining SW for GPUs. We will add these to our Neoscrypt links page as we get them.  FYI, one of the pools (https://ipc.theblocksfactory.com/) has a good write up on mining Neoscrypt coins.  Again, we thank you for your support of ImperialCoin.

OK, we have updated the new source code into our GitHub account and updated all the links on our website and this thread.  In regards to the fork, please note that we have also included a built in miner, so that the wallet is now self-contained.  You can solo or pool mine with the new wallet.  Prior to Block 66000, the miner will mine Scrypt normally. From Block 66000 forward, when the Neoscrypt algorithm begins in use, you will be using a Neoscrypt type miner.  Please let us know if you have any questions.  We have put links in the this thread and on our website relating to Neoscrypt and Neoscrypt mining.

We have finally completed our upgrade of Imperial Coin (IPC) from the Scrypt algorithm to the Neoscrypt algorithm. While this was not an easy choice as there are so many options out there now.  It has become clear to us that Neoscrypt will most likely be one of the next generation proof-of-work (PoW) algorithms designed to replace Scrypt. It consumes a lot less memory than Scrypt, but yet is more memory intensive and stronger cryptographically. The Neoscrypt algorithm combines the power of Salsa20/20, ChaCha20/20, BLAKE2s and FastKDF into a very secure ASIC-resistant solution. It is a VERY solid, well-designed and well thought out algorithm which we feel represents the next generation of coins that will now include Imperial Coin (IPC).

NeoScrypt has been running successfully on Phoenixcoin (PXC) since late July and will be on Feathercoin (FTC) starting in late October also. If you remember, the hashing technologies used by the Scrypt algorithm starts with PBKDF2-HMAC-SHA256 key derivation, and ends with 8 rounds of the Salsa20 cipher as its mixing engine. However, it has since been shown that only having 8 rounds of Salsa20 can be broken through differential cryptoanalysis - not as secure as we all thought.

So the Neoscrypt creator designed NeoScrypt to be compatible with Scrypt, but to have functional differences which provide significant advantages over Scrypt. With Neoscrypt, he has written a custom key derivation algorithm which is much stronger and faster. NeoScrypt's mixing engine employs 20 rounds of Salsa20, followed by 20 rounds of ChaCha20. Not only is this combination faster and more secure than standard Scrypt, but it only takes 32KB to 64KB of memory, compared to the 128KB of memory used by Scrypt.

We are thoroughly convinced that NeoScrypt based currencies are set to become the best option for those who have a low to medium budget for mining equipment and therefore cannot afford ASIC rigs. With the adoption of NeoScrypt by Imperial Coin (IPC), we ensure that our loyal miners, small businesses in need of payments systems and newbies everywhere will always be able to viably mine IPC by never having to compete against miners who have bought the next generation of expensive Scrypt ASICs.  Without and algorithm like Neoscrypt, the smaller hobbyist miner will have no place left to mine anything on Scrypt-based coins, just like GPUs have no place on Bitcoin any more. Only those with deep pockets can mine Bitcoin and this will end up being just a few large companies or well-funded individuals. In our view, this does not make a good case for decentralization and not where Imperial Coin (IPC) needs to go.

We thank you for your patience while we upgraded our algorithm and went through some minor programming difficulties causing some delays.  It is running now on several machines and on our seed nodes and has a delayed switchover that will make the switchover to the Neoscrypt algorithm on Block 66,000 - in about 3-4 days.  At that point, everyone will need to be switched over to the new version and be mining with either a CPU or GPU as your ASICs will cease to work properly with Imperial Coin after Block 66,000.

We still have much left to do in getting everyone alerted and switched over as well as our wallets and websites updated.  At this time, ONLY the Windows wallet is available as well as the source code for IPC V1.3.0.6 available from the links below only. Please upgrade to the new code as soon as you can and do not forget to backup your wallets first!

Quick status update.......

1) We just had our 700th Twitter follower yesterday!
2) Our fork is complete and appears to be working.  Another day of testing and we will announce it soon.

You are correct - we do not need all the alt coins out there right now.  Only the coins, who upgrade and stay current with coin technology will survive.  IPC is one like that.  Our upcoming fork, will make IPC a very competitive and technologically sound coin.  Thanks for your interest and comments.

there are thousand of Crypto Currency say that they are make for the 21st Century

  oh really ? why we need so much

Just a quick update on our fork status here.  We basically decided to start over on the fork and push it out a few weeks....what we had, seemed to work, but was not as stable as we would like it to be.  Pushing the fork out a week, will allow us to work on a few other minor bugs and do a little more thorough testing.  Meanwhile, we see a lot of hash power on IPC and good numbers on all the exchanges - hopefully, this will continue. Thanks for your support of IPC.

We are disappointed to report that we have to delay our planned hard fork that was planned for Block 60,000 by at least a week.  So if you had grabbed our source and done the Linux upgrade all went well for you.  But the Windows wallets had issues and most would never sync.  We have identified what the issues are and need to do some more work on the source code to solve this problem. We request that you all should revert to version 1.2 until we can get the problem fixed.  This is a stable version that we rolled out a few months back and has been running fine for everyone.  Right now, do not use any of the wallets on our website and please make sure you are using V1.2 and not the beta V1.3.

We apologize for the inconvenience.  But a fork of this nature is never easy and when all the Linux wallets synced properly we thought all was in good shape, until we tried the Windows wallets and had these issues.  We will get them fixed this week and get the new wallets out as soon as we can in time for a fork at around Block 64,000 - 65,000.  Thanks for your support of Imperial Coin (IPC).
