The CTF concept is dead on Solana.
You search for CTFs on Ethereum, and you find tons and tons of CTFs waiting for you to solve:
1. BuidlGuidl CTF
2. Capture the Ether
3. OpenZeppelin Ethernaut
4. ChainShot
5. Security Innovation Blockchain CTF
6. Damn Vulnerable DeFi
7. Paradigm CTF
Then you search for CTFs on Solana, and you find this:
An outdated Neodyme CTF from 5 years ago that's so old the dust will damage your eyes just looking at it.
Nothing else. Zero up-to-date CTFs.
I think CTFs are the main training ground for security researchers to practice, learn, and enjoy the game. On @solana, there's something off about that.
