After the FTX collapse, everyone has been asking: is the money I keep on exchanges actually safe? Is the exchange misusing user funds? Binance introduced Proof of Reserves so users can verify for themselves.
If you're still deciding whether to use Binance, you can review the Proof of Reserves first. After registering on Binance, you can check whether your assets are included. Download the Binance APP and find the entry in the security section.
What Is Proof of Reserves?
Proof of Reserves (PoR) is an audit mechanism proving that an exchange holds crypto assets no less than the total of user deposits.
In plain language: if you deposited 1 BTC on Binance, Binance needs to prove its wallets contain at least your 1 BTC (plus all other users' assets).
This prevents exchanges from secretly misusing user funds or becoming insolvent.
How to View Binance's Proof of Reserves
Viewing overall reserves:
- Visit the Binance official website
- Find the "Proof of Reserves" page (usually linked in the footer or announcements)
- View reserve data for each token
- Includes: user net balance, Binance reserve balance, reserve ratio
A reserve ratio above 100% means Binance holds more assets than total user deposits.
Verifying your own assets are included:
- Log into your Binance account
- Find "Verify My Assets" on the Proof of Reserves page
- The system generates a Merkle Tree leaf node for your account
- You can verify your assets are indeed included in the overall proof
Technical Principle: Merkle Tree
Binance uses Merkle Tree technology for Proof of Reserves:
- Each user's assets are hashed as a leaf node
- Leaf nodes are paired and hashed upward, culminating in a root node
- The root represents the sum of all user assets
- You can verify your leaf node truly belongs to the tree
- Other users' asset information remains private
This approach achieves both privacy protection and verifiability.
Which Tokens Does Proof of Reserves Cover?
Binance's PoR covers major crypto assets including:
- BTC
- ETH
- BNB
- USDT
- USDC
- Other major tokens
Binance continues expanding coverage to include more tokens.
Is Proof of Reserves Enough?
PoR is an important transparency measure, but not a cure-all:
What it proves:
- At a specific point in time, Binance's on-chain assets are no less than user deposits
- Your assets are within the audit scope
What it doesn't prove:
- Whether Binance has undisclosed liabilities
- The continuous state outside of snapshot moments
- Binance's operational risk and compliance risk
So PoR should be combined with other information for a comprehensive assessment — audit reports, regulatory compliance status, operational track record, etc.
What Other Security Measures Does Binance Have?
Beyond Proof of Reserves:
SAFU Fund: Secure Asset Fund for Users. Binance sets aside a portion of revenue as an emergency fund to compensate users in extreme situations.
Hot/Cold Wallet Separation: Most user assets are stored in offline cold wallets, with only a small portion in hot wallets for daily withdrawals.
Multi-Signature: Large transfers require multiple authorized signatures, preventing single points of failure.
Insurance Partnerships: Collaborating with insurance companies to provide a degree of coverage for user assets.
Regular Audits: Engaging third-party audit firms for financial audits.
What Should Users Do?
- Regularly check PoR: Make it a habit to periodically review Binance's reserve data
- Diversify risk: Don't put all assets on one exchange — spread them out
- Consider cold wallets for large amounts: Long-term holdings not being traded should go into your own hardware wallet
- Stay informed: If negative news about any exchange surfaces, promptly assess the risk
- Verify your assets: Use Binance's tools to confirm your assets are included in the reserves
Do Other Exchanges Have Proof of Reserves?
After the FTX incident, multiple exchanges began offering Proof of Reserves, with varying implementation levels. Binance was among the earliest and most proactive large exchanges to push PoR.
When choosing an exchange, whether they provide verifiable Proof of Reserves should be an important consideration.
Proof of Reserves represents an important step toward transparency in the cryptocurrency industry. While it can't eliminate all risks, it gives users an objective basis for judgment.
