Jump-Oriented Programming(JOP) on EVM is like ROP in Ethereum smart contract. It can be used in smart contract honeypot to hide backdoors, and probably can be utilized in other ways at other platforms.
It's been implemented first during Realworld CTF 2018 World Final, the Acoraida Monica challenge, designed by me.
Special thanks to @peter50216, from team 217. He's the only one solved this challenge during the 2-day Realworld CTF, which makes this challenge complete.
Special thanks to @liveoverflow. He made a great video serial to explain his approach and throughts about this challenge:
