Not written in pure lua... pretend this is pseudo-code
Was written for the ROBLOX Platform to see if distributed Bitcoin Mining through a video-game that allowed scripting capabilites was possible, as well as for fun and profit.
Turn's out it kinda is! Most of the code is snippets from other people, such as the Bit operations, SHA256 in Lua, and Knuth RNG.
