The core purpose of the Security Fund is to absorb the shortfall created by "bankrupt positions."When a position is forcibly closed (liquidated), the system attempts to execute the trade in the market. If, due to rapid market movements and high volatility, the executed price is lower than the account's bankruptcy price, the resulting deficit (the excessive loss) is covered by the Security Fund.

It takes 3 hours on a single 10-core machine, compared to previous version's 36 hours using nine 64-core machines. This speedup is due to the usage of the Plonky2 framework, which compiles Rust-coded circuits into efficient machine language instead of using slower Python scripts. We also enhanced Plonky2 to run some computations on GPUs, reducing the time by an extra 30%. Better auditability: With Version 2, we use a high-level framework that handles complex cryptographic details for us.
