OKX Introduces zk-STARK Technology to Proof of Reserves, Monthly Snapshot Shows $10.4B in BTC, ETH, and USDT

·

In a major leap for transparency and user trust in the cryptocurrency industry, OKX has unveiled the most significant upgrade yet to its Proof of Reserves (PoR) system. By integrating zk-STARK zero-knowledge cryptographic technology, OKX now empowers users to independently verify the exchange’s solvency with enhanced privacy and security. The latest monthly PoR report reveals reserves totaling $10.4 billion across Bitcoin (BTC), Ethereum (ETH), and Tether (USDT)—a 39% increase since January 2023.

This advancement underscores OKX’s commitment to setting new standards in exchange transparency, offering real-time, trustless verification tools that put control directly in users’ hands.

What Is zk-STARK and Why It Matters

Zero-Knowledge Scalable Transparent Argument of Knowledge (zk-STARK) is a cutting-edge cryptographic protocol that enables one party to prove the validity of data without revealing the data itself. In the context of Proof of Reserves, this means OKX can demonstrate it holds sufficient assets to back user balances—without exposing sensitive account information.

Unlike traditional audits or simple balance snapshots, zk-STARK provides mathematically verifiable proof that:

And crucially, no individual account balances are exposed, preserving user privacy while ensuring full transparency at the aggregate level.

Enhanced Reserve Transparency with Real-Time Verification

OKX has long been a pioneer in exchange transparency, publishing tens of thousands of wallet addresses as part of its Merkle tree implementation. With this latest update, users can now leverage trustless tools to cross-check their own balances against the global reserve ledger—anytime, anywhere.

The current reserve ratios stand at:

These figures confirm that OKX holds more than enough assets to cover all user holdings in these major cryptocurrencies, providing a critical buffer against market volatility.

Expanded Asset Coverage: Now 21 Cryptocurrencies Verifiable

For the first time, OKX has extended PoR verification to 18 additional cryptocurrencies, bringing the total number of supported assets to 21. This expansion significantly broadens the scope of transparency beyond flagship tokens.

The newly included assets are:

This means holders of these tokens can now independently verify that their assets are fully backed by on-chain reserves—using open-source tools and public Merkle proofs.

Why Proof of Reserves Is Essential for Crypto Trust

Following high-profile exchange collapses in recent years, Proof of Reserves has emerged as a cornerstone of responsible crypto platform operations. It addresses a fundamental question: Can users trust that their funds are actually held by the exchange?

OKX’s approach goes beyond static reports. By publishing PoR monthly and enabling real-time verification through zk-STARK-powered systems, the platform fosters continuous accountability.

Lennix Lai, Chief Commercial Officer at OKX, emphasized:

"Proof of Reserves is an indispensable way to demonstrate transparency and guarantee solvency. It builds user confidence and trust in the industry as a whole. OKX is committed to leading the crypto space by empowering users to verify reserves and liabilities in real time using trustless 'future tools' like Proof of Reserves."

How Users Can Verify Reserves Themselves

Verification is simple and does not require technical expertise:

  1. Visit the official OKX Proof of Reserves portal.
  2. Locate your account’s Merkle leaf within the published tree.
  3. Use the zk-STARK verifier to confirm your balance is included in the total reserve.
  4. Cross-reference the on-chain wallet addresses holding OKX’s assets.

Because zk-STARK proofs are publicly available and independently verifiable, no third-party auditor is needed—just math and transparency.

Industry Impact: Raising the Bar for Exchange Accountability

OKX is one of the few major exchanges to release monthly PoR reports with full technical backing. While some platforms offer occasional audits or partial disclosures, OKX’s combination of frequency, scope, and technological sophistication sets a new benchmark.

By embracing zk-STARK and expanding asset coverage, OKX reinforces its position as a leader in Web3 infrastructure innovation—not just as a trading venue but as a builder of trust-minimized systems.

This move also aligns with growing regulatory expectations worldwide for greater financial transparency in digital asset platforms. As regulators seek clearer oversight mechanisms, solutions like zk-STARK-based PoR offer a path forward that balances compliance with decentralization principles.

Frequently Asked Questions (FAQ)

What is Proof of Reserves (PoR)?

Proof of Reserves is a cryptographic method that allows cryptocurrency exchanges to prove they hold sufficient assets to cover all user balances. It uses Merkle trees and on-chain verification so users can confirm their funds are backed by real reserves.

How does zk-STARK improve PoR?

zk-STARK enhances PoR by enabling private, scalable, and trustless verification. It allows OKX to prove reserve accuracy without revealing individual account data, offering stronger privacy and security than traditional methods.

Can I verify my own balance?

Yes. Using the public Merkle tree and verification tools on OKX’s PoR page, you can check whether your account balance is included in the total reserves—providing direct, independent confirmation.

Why is 103% reserve ratio important?

A reserve ratio above 100% indicates that OKX holds more assets than user liabilities. This buffer helps ensure solvency even during periods of high withdrawal demand or price fluctuation.

Are stablecoins like USDT and USDC fully backed?

According to the latest PoR report, both USDT and USDC reserves exceed user liabilities at a 103% ratio. Independent verification tools allow users to validate these claims on-chain.

How often is Proof of Reserves updated?

OKX publishes its Proof of Reserves report monthly, making it one of the most consistently transparent exchanges in the industry.

Looking Ahead: The Future of Trustless Verification

As the crypto ecosystem evolves, so too must the tools that uphold its integrity. OKX’s integration of zk-STARK into Proof of Reserves marks a pivotal moment—where transparency is no longer dependent on trust in intermediaries but verified through code and cryptography.

This shift toward self-sovereign verification empowers users, strengthens platform accountability, and paves the way for broader adoption of decentralized financial systems.
