ProgPOW implementation in WebGL

This repo will contain a ProgPOW implementation in WebGL.

TODO

• Keccak256 + Keccak512
• Make cache
• Agg. data (FNV hash)
• Dataset calculation
• Hashimoto loop
• PoW setup

I think we can make the cache size constant, let's say, 1 GB, to make it accessible for all GPUs. For example, I have an intel GPU with only 1536 MB of VRAM :)
