Memory-bound trapdoor proof of work

  a memory-bound graph-theoretic proof-of-work system (by tromp)

Non-Solution #8: Cuckoo Cycle https://github.com/tromp/cuckoo Why: At least a few people have looked at it, and any attacker is far more likely to directly attack the blockchain itself, than my server (which doesn't get involved with the blockchain) Why not: The "mathematical specification" https://github.com/tromp/cuckoo/blob/master/doc/mathspec is woefully inadequate, their "C spec" focuses more on ASCII art than actual readability https://github.com/tromp/cuckoo/blob/master/doc/spec and as https://handshake.org/files/handshake.txt points out, cannot be easily adjusted in difficulty. Also, I would need to implement it from scratch, but I guess I'll have to do that anyway.

• Atomic

  1 4 0.0 C++

  denis bider's Atomic library (C++, for Windows) (by denisbider)

Non-Solution #10: Busy Beaver (64kb random instructions) https://denisbider.blogspot.com/2015/05/busybeaver-key-derivation-function.html Why: Has a public JS implementation, neat! Why not: Not well-documented, only available as a zip, or I could rip it out of this (abandoned?) repo https://github.com/denisbider/Atomic , apparently hasn't really been cross-checked by anyone it seems.
