Even though ePT algorithm is SHA-256 there is wip for spow, meaning any of "old" claims of being asicable are not valid. Further studies took us to the conclusion we would need indeed a "CPU-only" algorithm to keep us "CPU-only", however, we all know this is only temporary. You can "watch" for instance XMR evolution which aims to keep itself CPU-only mineable. Spow comes in, spow disallows any sort of "temporary" CPU algorithm. For legendary members to understand, where you would think ASIC would be possibility it simply won't. This is a complex problem, cause we are not only trying to solve adoption by minorities with less expensive hardware such as IoT devices but are also concerned with "banning" botnets and pool-mining. The aim is to keep it CPU, however we concluded GPU is also a possibility within core. Making ePT a "solo-gpu" coin even though using SHA-256. This is however sad on our eyes, cause let's face it, we want "less-expensive" (IoT) devices to be allowed along with expensive CPUs. For us to keep fairness extra measures would have to be taken ( such as a "limiter"), RAM is a possibility to "kick" out not-so-expensive GPUs (e.g. add a 32gb scratchpad loaded within RAM).     

CryptoNote started as Bytecoin CryptoNight algorithm, a L3 cache bounded structure, and evolved to ASIC's, meaning measures have to be taken along time to keep either up or against ASIC manufacturers.

Seen options:

1. Keep it CPU/GPU minable along a big-sized scratchpad loaded in RAM.
2. Ditch spow idea and go SHA-256 mineable with ASIC's. ( pool-mining)
3. Any other

Our aim is / would be to keep SHA-256. However in 1st option to "kill" old gen/not so expensive GPUs we are also "killing" IOT devices. We strongly believe there should be an option along a fast algorithm as SHA-256 is.

Ideas are welcome.
