🪙 Vitalik Buterin wrote an article about obfuscation — one of the most powerful and complex tools in cryptography, which allows a program to be run such that the result is visible, but its internal logic remains hidden (under the hood).

In theory, together with blockchain, this could provide almost a "trustless trusted third party" — private voting, complex protocols without committees, and new cryptosystems.

But for now, the main problem is very severe — secure obfuscation already appears mathematically possible, but it works so slowly, that Vitalik calls it almost a "galactic" level of cost.
