Backpack Exchange has officially launched real-time Proof of Reserves, built and verified by OtterSec, and is committed to daily public disclosure. This system, based on zero-knowledge proof technology, covers spot trading, margin trading, and unrealized profit and loss. Users can verify their account balances through a Merkle tree without exposing their privacy. Compared to the industry's standard monthly disclosure, Backpack provides daily disclosure and internal verification every 10 minutes. In the future, Backpack will gradually achieve full public disclosure of code and data, making centralized exchanges verifiable on-chain.
