Cryptocurrency exchange OKX has released its sixth proof-of-reserves (PoR) report, reinforcing its commitment to transparency in the digital asset industry. First initiated in November 2022 in the aftermath of the FTX collapse, this ongoing initiative aims to build trust by publicly verifying that customer funds are fully backed.
As of the latest audit, OKX holds over $8.9 billion in Bitcoin (BTC) across its reserve holdings. The exchange reports reserve ratios above 100% for major assets: 103% for BTC, 103% for Ethereum (ETH), and 102% for Tether (USDT)—ensuring that for every user deposit, there is a corresponding on-chain asset to back it.

Enhanced Transparency with Public Liabilities Disclosure
A significant advancement in this latest PoR report is the public disclosure of total user liabilities—the aggregate sum of all customer deposits. While previous reports focused on proving asset holdings, OKX now provides a more complete picture by revealing liabilities, allowing external parties to calculate reserve coverage ratios independently.
Despite making aggregate deposit data public, OKX ensures user privacy is preserved through an innovative technical solution: splitting and shuffling account liabilities using splitting leaf nodes within the Merkle tree structure. This method allows transparency at the system level without exposing individual account balances.
This dual verification of assets and liabilities marks a pivotal step forward in exchange accountability, setting a new benchmark for what users should expect from responsible crypto platforms.
Growing User Engagement and Trust
Lennix Lai, Managing Director of Global Institutional at OKX, shared with Cointelegraph that over 300,000 users have actively verified their balances or explored the exchange's reserve data within the OKX ecosystem. This level of engagement highlights increasing user awareness and demand for verifiable financial integrity.
Lai also confirmed that OKX plans to integrate zero-knowledge proofs (ZKPs) into its PoR framework in the coming weeks. This cryptographic enhancement will allow the exchange to prove solvency without revealing sensitive data, further strengthening both security and privacy.
The move toward ZK-based verification aligns with broader industry trends. For instance, Binance recently upgraded its proof-of-reserves system on February 10 to support zk-SNARKs, a form of zero-knowledge cryptography that enables efficient and private validation of reserve holdings.
Why Proof-of-Reserves Matters in Crypto
The importance of proof-of-reserves surged following the collapse of FTX, which exposed critical vulnerabilities in centralized exchange oversight. In response, major platforms like Binance, Crypto.com, and Bybit have adopted Merkle-tree-based PoR systems to independently verify their asset reserves.
Unlike traditional finance, where audits are often delayed and opaque, blockchain-based proof-of-reserves enables real-time, on-chain verification. Users can check whether their funds are truly backed—anytime, anywhere—using publicly accessible data.
This shift empowers users with unprecedented transparency, turning trust from a blind assumption into a verifiable fact.
However, it's important to note that not all regulatory bodies view PoR reports as sufficient. The Public Company Accounting Oversight Board (PCAOB) in the U.S. has cautioned investors, stating that such reports “do not give any meaningful assurance to investors or the public.” Their concern stems from the fact that PoR only confirms asset existence at a point in time and does not verify operational soundness or long-term solvency.
Still, within the crypto ecosystem, PoR remains a critical tool for building confidence—especially as users grow more sophisticated and vigilant.

The Broader Push for Financial Transparency
The demand for greater transparency isn't limited to crypto. The failure of Silicon Valley Bank (SVB) intensified global conversations about financial accountability across both traditional and digital sectors.
In traditional finance, audits are typically conducted quarterly or annually, leaving long gaps between verifications. In contrast, crypto-native solutions like OKX’s PoR offer near-instantaneous validation powered by blockchain technology.
This contrast underscores one of crypto’s core value propositions: trustlessness through technology. Instead of relying solely on institutional promises, users can rely on cryptographic proof.
As regulatory scrutiny increases and user expectations evolve, exchanges that prioritize openness—not just compliance—are likely to lead the next phase of industry growth.

Frequently Asked Questions (FAQ)
Q: What is proof-of-reserves (PoR)?
A: Proof-of-reserves is a cryptographic method used by cryptocurrency exchanges to prove they hold sufficient assets to cover all customer deposits. It typically involves publishing a Merkle tree that allows users to verify their balances are included in the total reserves.
Q: How does OKX protect user privacy while sharing liabilities?
A: OKX uses a technique called splitting leaf nodes to shuffle and divide account liabilities in the Merkle tree. This allows the total deposit amount to be public while keeping individual user data private and secure.
Q: Why is a reserve ratio above 100% important?
A: A reserve ratio over 100% means the exchange holds more assets than customer deposits—indicating strong liquidity and reducing the risk of insolvency. OKX’s ratios (103% for BTC/ETH, 102% for USDT) demonstrate robust backing.
Q: Can proof-of-reserves prevent exchange failures?
A: While PoR cannot guarantee an exchange won’t fail due to operational or strategic issues, it significantly reduces the risk of fraud or misuse of funds by providing transparent, real-time verification of asset holdings.
Q: What are zero-knowledge proofs (ZKPs), and why are they important for PoR?
A: Zero-knowledge proofs allow one party to prove knowledge of certain information without revealing the information itself. In PoR, ZKPs enable exchanges to verify solvency without exposing sensitive financial data—enhancing both security and privacy.
Q: How often does OKX publish its PoR reports?
A: OKX has been publishing its proof-of-reserves reports regularly since November 2022. The latest release marks its sixth edition, reflecting an ongoing commitment to transparency and user trust.
