Short info about Cryptonight Adaptive algo

Nerva (XNV) GPU and ASIC resistant Cryptonight Adaptive POW algorithm.

CN-Adaptive-v2 strengthens the solo CPU mining goals of NERVA, by making it a requirement to have a local blockchain copy and strenthens the concept of ASIC resistance via dynamically adjusting the hash algorithm. v1 created 1024 different algorithm variations. v2 expands that randomization by orders of magnitude. Consider that 32 out of a possible 1,048,576 scratchpad bytes are changed, with each byte changed in one of 8 possible ways, by one of 256 potential operand values. Furthermore, each of those possible combinations can be performed up to 64 different ways via the variable AES iteration count.

The cost of this however is sync speed. A node blockchain must be synced one block at a time, so that the previous block hash can be read to generate the required information to randomize the scratchpad. CN-Adaptive-v2 must therefore be accompanied by a bootstrap method of chain synchronization to speed up synchronization times and improve the end user experience.

It is also important to distinguish that CN-Adaptive-v2 is not exactly a modification to the CN Variant 1 as used by Monero.

CN-Adaptive-v2 creates a secondary algorithm which generates a random dataset that is applied to change the scratchpad buffer to change the resulting hash produced by Cryptonight. As a result, CN-Adaptive-v2 could be applied to any cryptonight variant that may seek to promote Solo CPU mining as it's method of distribution.
