A16z upgrades Jolt zkVM and introduces zero knowledge support

A16z Crypto stated in its latest blog that some zkVMs do not truly achieve zero knowledge privacy and only have "simplicity", leading to the generalization of the "ZK" tag. On the same day, A16z introduced the NovaBlindFold folding solution for the open-source Jolt zkVM, achieving native zero knowledge support to prevent information leakage. The upgraded proof generated only increased by about 3KB compared to the original non-zero knowledge version.
