Can anyone explain please:
- Why we need a hardfork (or not)?
- What about the scratchpad ?
there are gpu miners for wild keccack now (which is used by bbr).
as this coin is intended to be cpu only there is a scratchpad needed for mining (just as a added memory requirement).
a gpu dev figured out how to store it effeciently: so we are talking about a hardfork to change the size of the scratchpad (or to change anything else we want to)
to be more correct - wild keccak scratchpad is increasing with each block. Now scratchpad is about 7Mb. It will grow about 90MB per year, and, since at this moment scratchpad is not big enough - it is possible to use gpu textures cache to mine it faster, as i know.
But according to dga calculations gpu miner is about 2.3 times more cost-effective than cpu, since big advantage gives only expansive cards.
PS: Probability of that i'll do hardfork is less than 1%. Now we focused on optimizing miner and implementing stratum pools.
Basically GPU miners currently have an advantage, but it's not such an extraordinarily large advantage (And this advantage will decrease over time) that it's not worth it to hard fork for this reason, right?
