Technical Breakdown: How Proof of Reserves Works
The zk-STARK Verification Process
Our system uses Zero-Knowledge Scalable Transparent Arguments of Knowledge (zk-STARK) to:
- Protect user privacy while proving asset holdings
- Create tamper-proof records via encrypted Merkle trees
- Automate validation through three core constraints:
| Constraint Type | Verification Purpose |
|---|---|
| Total Balance | Confirms sum of all account balances |
| Non-Negative | Ensures no negative asset positions |
| Inclusion | Validates every account's inclusion |
Wallet Verification Methods
- Signed Address Confirmation: Each OKX wallet contains "I am an OKX address" message
- Open-Source Tools: Available for public verification of ownership and balances
- Third-Party Audits: Compatible with external blockchain analysis tools
