Key technology being used in Museum Heist
Math in the dark (homomorphic encryption)
homomorphic encryption is a special kind that, apart from keeping data secret, also allows arithmetics (e.g. + - x %) on the encrypted data and operand. This means we can secretly subtract the museum's artifact balance and add it to your secret vault balance without revealing the actual number.
Enforcing rules in secret (zkSNARK)
zero-knowledge-proof technologies allow users to proof statements without revealing any extra information. This means we can prove that the amount of artifacts that users steal is equal to the amount they add to their vault without revealing the actual numbers.
zkSNARK is a zero-knowledge-proof technology that can be proven in smart contracts efficiently.
Here are resources if you want to learn about the technology seriously.
