The raven coin is a good coin regard with the thing they wana do : asset transfer on blockchain
But I have to say x16r is not ASIC resistant.
As we all know , DASH asic miner is produced. The difference between X16R and X13 is : the hash order in
X13 is fixed and X16R is changed according to the previous HASH value.
But unfortunately , in ASIC , this change is so easy to implement. The brief solution is :
reg [4*16-1:0] hash_val;
always @( posedge clk)
if ( one_of_16_hash_done)
hash_val <= hash_val <<4 ;
and the asic implement all 16 hash. The process likes as flows:
when hash_val is x(for example, first 4 bit value is 0) , blake hash start to run,when black hash done ,it responds to above code
hash_val shift to next four bits, and the hash_val is y(for example , first 4bit value is 1) , then bmw hash start to run,when done ,it responds
to above code ....
---------------------------------
And the dev has to change the 16 hash algro to fight back, but in this way, it can't say this algro is anti-asic, as X13 can also change its 13 hash algro, or just like XMR does, change the code.
------------
But I have to say the X16R algro is one of the feature of RVN, RVN's idea of assets is great. Just x16r is not really resistant-ASIC
Someone else mentioned something similar and I have an inkling is it is the Pigeoncoin dev.
Do you know why DASH hasn't hard forked?
Do you know if it is chip per algo or an ASIC can be programed to do all?
I suppose it is the threat that is there and possibly easy to change and the current Devs are saying they will change and have plans they are keeping to themselves.
How about the scenario where the ASICS are detected (or guessed) on the network and the algo is changed to hex digit (N)+1 unless N=F which then will be (F)-F = 0
I suppose They could make a controller that is updatable.
Then do they need a chip for all 16 algo (or more) to cover an algo swap. How many chips will they need to cover all known algos?
Add more memory intensive algos - the ASISC would be limited on the speed of the memory. I think it is still debatable that Mem ASICS can be created or am I still behind the times???
So the threat to change it is there and it may put them off a bit.
Also the consumer market is scared to buy the ASICS due to the threat so that would be a risk if they wanted to release to that market.
