Hello!

This is a formal announce of yacoin: yet another coin based on novacoin sources. Hash algo is changed from scrypt(1024, 1, 1) to scrypt(N, 1, 1). Parameter N increases over time making HW or GPU implementation more and more impractical (but yet possible).

Using scrypt(N, 1, 1) means that only solo cpu mining will work until someone will fork mining pool software or implement GPU miner. All existing miners aren't compatible.

The core idea is that we have to use and to try different hash algos to make cryptofinances more secure and stable.

Note:
Incrementing N will lead to immediate hashing speed decrease. Difficulty will reflect these speed changes (i.e. difficulty will decrease after N++) with lags. As soon as block reward depends on difficulty the reward will increase also and more miners will be motivated to join after N++.  It's not easy to predict now but we can be sure that some waves will happen on each N++ event.

Release and all details (ports, links to sources and binaries etc) will be available here in 24 hours.
No premine is planned: the blockchain I use now for testing will be deleted before release.
