Where I can find detailed description of x16 algo? What the exact difference of X16 from X11 or X13? I have browsed the website, but didn't find clear descriptions of X16 algo.
x16 is asic immune and a mixup from another algos :
The X16R hashing algorithm consists of 16 hashing algorithms operating in chain
fashion with the ordering dependent on the last 8 bytes (16 nibbles) of the hash of the
previous block. The algorithms are as follows:
0=blake
1=bmw
2=groestl
3=jh
4=keccak
5=skein
6=luffa
7=cubehash
8=shavite
9=simd
A=echo
B=hamsi
C=fugue
D=shabal
E=whirlpool
F=sha512
