argon2d is anti-GPU
It is no longer true, there are many miners that allow GPU mining using argon2d. More explanation here:
https://www.reddit.com/r/garlicoin/comments/7wf3m6/argon2d_is_gpu_resistant/dyrir63/?utm_source=reddit&utm_medium=web2x&context=3Currently, the most GPU/ASIC resistant functions are probably yescrypt-based. But in reality, there is no such things like "ASIC-resistance". People are not building ASIC machines for such algorithms, because now it is not profitable yet. But when some altcoins will be worth more, they will be created sooner or later. And the only defense in all such cases is changing an algorithm, but it possibly leads to creating a new coin.
GPU resistance is regularly broken on many algorithms, because it is easier to get some GPU hardware and write some code than create some ASIC device from scratch.
you just did some quick googles and jumped to a false conclusion.
Luck uses argon2id (not argon2d) with heavy parameters that makes GPU almost equivalent to CPU. To be detailed, memory cost is 64mb, parallelism cost is 4, time cost is 2. Other argon2 projects can be mined by GPU because they use lightweight parameters, such as memory cost is only 1mb. You can test it for yourself, or ask a real expert about this.
Plus, for mining a block the miners have to do 3 rounds of argon2id. So GPU miner is definitely unrealistic here.
It's dead. It's monopolized by a few miners.It's not luck at all.
I analyzed the 2POW protocol.
In the early days, everyone used CPU mining, as the more nodes, the higher the luck value.
However, since some time, some GPUs have participated in mining, and the power has increased by about 1000 times. The CPU can no longer mined blocks at all, and luck is not so important. Because in the design of 2POW, there is a basic assumption that when the power of all nodes is almost equal, blocks are mined by luck. However, GPU has a performance advantage of 1000 times compared with CPU, this is equivalent to only a few scattered GPUs in the system mining blocks.
Although the system has been monopolized by several GPU miners, I believe that as the number of GPUs increases, the importance of luck will come.
same reply as above. No GPU here. I myself only mine with 4 x i7-6700k and have blocks everyday
