MindBreed is a CryptoKitties powered Brainfuck interpreter.
Brainfuck is an esoteric programming language with eight instructions (>, <, +, -, ., ,, [, ]). Using these eight instructions, you can run programs that produce output.
MindBreed is a special type of Brainfuck interpreter that doesn't understand text input - only the fur patterns on CryptoKitties. Instead of simply typing out instructions, you must sacrifice an innocent kitty to the EVM for each added instruction.
Here are the equivalent instructions:
| Fur Pattern | Instruction |
|---|---|
| savannah | + |
| selkirk | , |
| birman | - |
| koladiviya | . |
| bobtail | < |
| pixiebob | > |
| cymric | [ |
| chartreux | ] |
You can only add instructions onto the end of your program. You can pop instructions off the end, but you don't get your kitty back. Every MindBreed contract comes with a bounty - if you execute the right program, you get that bounty. Happy sacrificing.
This project makes use of the Brainfuck interpreter written by Greg Hysen for the Solidity Gas Golfing Contest.
