1) At the lowest layers, blake2b and siphash are used as hashing and PRNG
algorithms that are well suited to common 64-bit CPUs.
- 2) A custom hash function, HashX, uses dynamically generated functions that
- are tuned to be a good match for pipelined integer and floating point
- performance on current 64-bit CPUs. This layer provides the strongest ASIC
- resistance, since a reimplementation in hardware would need to implement
- much of a CPU to compute these functions efficiently.
+ 2) A custom hash function family, HashX, randomizes its implementation for
+ each new seed value. These functions are tuned to utilize the pipelined
+ integer performance on a modern 64-bit CPU. This layer provides the
+ strongest ASIC resistance, since a hardware reimplementation would need
+ to include a CPU-like pipelined execution unit to keep up.
3) The Equi-X layer itself builds on HashX and adds an algorithmic puzzle
that's designed to be strongly asymmetric and to require RAM to solve
efficiently.
